Best of best resource I have ever found online during my 3-day research on shingles! You did an outstanding work! I was struggling among OC Duration, GAF Timberline, and CertainTeed. Now you are the ONLY one giving out non-BS info/data. THANKS!
Yeah curious who did you go with. I'm in the same boat. Need to decide by next Friday lol. Between GAF timberline hdz Owen's corning duration cool and landmark Solaris.
I've made the decision to switch to CertainTeed Landmark, I've installed Tamko for the past 5 years, this video really helped back up my decision, thank you.
Very good information, I am a roof consultant and my first goto shingle is always Malarkey, I wasn't surprised by your results. This is a good reminder to my clients who are looking for good roofs not more problems.
Excellent review comparison! Today just had Owen Corning Duration installed and this review confirmed my wise choose. The driftwood color is beautiful. The Polish roofing company I used strongly recommended OC Duration, and they (and you) were right!
Great informational video. I discovered an apartment building I own in North Idaho needed a new roof unexpectedly. I needed to educate myself on roof shingles and their installation process. I really enjoyed your information and presentation. Your comparisons have certainly helped me pinpoint my contractor and materials. Please keep it up and we need to get a Directorii contractor in North Idaho.
Thanks for posting this video. I am getting ready to sign a contract with a roofer and they suggested Malarkey as the better option and Tamko as the cheaper option. I had never heard of either shingle. Your video hellped reinforce my decision. Be well.
Great info!!! One point given for all comparisons. Highest priorities for me are: sealant Pull test Nail zone Granule loss Warranty Performance, durability and performance. Thanks
I think a wind test would be fun. I love what you do you inspire me to run my company the best way possible. Which is why i have the best reputation in my area, and keeps us booked months out all year long!
They all pass wind test when brand new. Harder to do it when it’s one year on the roof. Because it’s this year test, wind test would be last years lol. But will keep thinking about how to do it
Top 3 make perfect sense, all good quality. I would be curious to see a real life audit of 5 to 10 year old installs. Sample several as you travel the country to see how climate and age impact performance and appearance. There are clearly fans of various brands represented in the RI community. As always, great video for contractors and homeowners.
I would be one of those salespeople! Based on everything I learned OC is my choice because of the high score and overall look. Thanks for all you are sharing!
I just had Corning Duration shingles installed on my bungalow in Canada. I chose Onyx black and they look great. I picked a small piece off the ground when they were Installing and could not break it. I could see the fiberglass in there. Great underlay too. i'm glad I went with the corning.
Thanks for your vids...very informative. More people should watch them before they make uninformed decisions. Its like buying a car..you can't return it. Thanks again.
I agree with you on Granule Loss rating. My roof is eleven years old IKO Cambridge Architectural Shingles, I still have to clean the rain gutter twice every year due to high granule loss. I won't use the product again. I recently found a tap of the shingles at an edge blown away due to high wind.
Thank you for the video! This coming Tuesday I have one of your guys in your directory coming out to give me a quote on a sheathing removal and re-roof with O.C Duration. I'm in Illinois so we'll see how it goes. Thank you for the directory too! Keep educating us.
"We believe that if the shingle has major problems with the granule loss in the beginning, most likely in the lifetime, it's also going to be the case." Would you say that granule loss reduces the longevity of a shingle? If so, then from a homeowner's perspective, this is a very important rating category. Perhaps it should be weighted higher than some of the others. Perhaps you should have more than one overall rating system: one for the shingling company and another for the homeowner. Or maybe add a rating system based on overall durability of the shingle, using the factors that contribute to that. Thanks again for this video. Very well done.
If manufacturers cant keep granules on shingles immediately after install how can we trust they will stay later? We trust those who made granules to stay out of the box more, just common sense
Yeah, I think nailing flange and granular lost should be more weighted in the total, as they are big issues that the companies don't end up covering, and you end up fighting with them to get no where.
Excellent review 👏 👌 👍 🙌 Excellent, thanks a lot, if I new or so read this I would be having a piece of mind. I just got Tamco, on my roof 😐, I will get ready for legal action if needed. S.....hit, I'm scared 😱 😨.
As a @malarkeyroofingproducts certifed installer, no surprise to me. No surprise on the Shamko rating either, pure garbage. Great job! Thanks for the effort!
Thanks for feedback! Roofing shingles look similar, but only certified installers who deal with shingles daily can tell the real difference between Malarkey and Tamko. Yet many roofers still will tell you that "all shingles are the same"
GAF's lack of a backbone to be reviewed and compared to other shingle manufacturer's products, automatically takes them out of the running for my re-roof job coming up. So, take that GAF!!!! I'm also looking for a Green color, so that knocks others out of the contest too!
So informative. I want a blue shingle which is very limiting. Malarkey and Atlas are out. I was leaning toward the Iko Dynasty, but now I'm second guessing that. OC Duration might be the winner. Although it seems a lot of roofers are fans of Certainteed. I hate making grown up decisions.
I don't have a problem with how you did your testing and I have my opinion and I rely on what our roofers say since they install these products every day. They rate the OC Duration way above the Landmark and I'm a CT fan or at least used to be. I was one of the top sellers of the Malarkey products since 1992 in the Denver Front Range area up until 2013 when the contractor I sold for had a negative bias for Malarkey but they were a cheap minded company. The tear test is an interesting test, I would like to see more of that alone and can it be done differently, probably. Wind tunnel tests would be a good video to produce. Thanks for all your effort none the less.
Great info, at the end of the day the product is only as good as the installation and 2 roofs with the same shingles can have very different lifespans based on instillation which is always gonna be the wild card!!
You reviewed IKO Dynasty, but for the 1 star granule loss section you said it was for Cambridge. Did you just misspeak on that? I recently ok'd my roof to be done next month with IKO Dynasty. The Cambridge line gets a bad rep and I think that blends into why the online reputation is bad for IKO too. Cause it's based on Cambridge. Everything I've read and watched, including some of your prior videos, suggest Dynasty is a pretty solid product. Thanks for taking the time to make videos and pass along information. You really helped a small common homeowner like myself make a decision a few weeks ago!
I believe that was a misspeak. I also don't believe the granule loss category makes sense. The excess "carrier" granules in a bundle are overspray and didn't come off the shingle. They were never on there to begin with. The shingles themselves are completely coated. Probably money lost by the manufacturer, but its not granule loss. That can happen, but its after years on the roof. It shows as shiny spots on the roof when so many stones come off, you can see the fiberglass mat.
Malarkey has always preformed well. I have lost 1 Malarkey shingle in 36 years, the winds exceeded 130 mph just after installation. Certainteed is the only shingle i have seen blow off twice in 2 years and both roofs were installed excellently, i had to go back later and hand tab the entire 60 square roof after Certainteed bought the home owners a brand new roof.
I have not used this shingle yet. I have used other "solar shingles" . They were a little cooler but the color was frosty and muted. Malarkey only makes shingles and roofing underlayments . I trust them and their products , their tech support is excellent. Thanks for the reply.
@@chrisginoc for what its worth, I had a roofer bring by some full sized shingle samples so I could examine them.. a certainteed, malarky vista and ecoasis.. I tried the roll up test on all of these, rolling them tight, tar side out, like a burrito.. then unrolling and examining how well they held up...the certainteed cracked in alot of places and showed damage when unrolled on the granule side as well as on the black tar side... the ecoasis also cracked when rolled up..not good and Not like any tests ive seen online where they were damage free... lastly, i did the vista..it felt noticeABLY more flexible than the other 2 which seemed similiar in granules and construction but the vista seemed a different animal... more flexible, granules adhered much better and it had the least damage, almost none,when unrolled... In the shingles defense, I did the test in about 70 degree temps...I have a feeling, the online tests where done by leaving the shingles out in the sun to get hot, then folding them...my tests were torturous to those shingles...after rolling up, i stood on them, then unrolled... painful for the roofer to watch and he was impressed with the results... me, less so becuz I was expecting No damage at all... he said any normal asphalt shingle would break under that test.
I called Erie metal roofs. When they came instead of selling me a metal roof. They brought two guys out to gang up on me, to pressure me into buying there Asphalt roof. The cost for the asphalt roof was almost 10 times as much as my original roof 21years ago. And they were putting a second layer. Without a Tear off!
THANK YOU SOOOO MUCH!!!! 🙌 Your video helped me make my decision on which Company to choose for my roofing job on my home 😁 Excellent Presentation 👏👏👏 Well Done!
Hey you are doing great job educating homeowners and contractors roofer’s, please keep informing the public , many homeowners do not check the product before buying , Thanks for your information 👏
Thanks so much for the information, decisions, decisions but your work certainly is making it easier. Thanks so much. We just had a roofer start a quote for us today, he generally goes with Tamko or Atlas, makes me slightly nervous to hear he uses Tamko after seeing your review but maybe it's a 3.7 meal vs the 4.6. If the price is the same I'll probably God willing be going with the Atlas indeed. Thanks so much. He's been doing it for years and mentioned how much grit comes right out of the bags of the GAF and mentioned that he wonders how much stays on the shingle and that it is also dangerous which I believe I heard you mention in either this video or a previous one. Thanks again, great, great stuff. One thing that seems to be a big up seller at least around here and I'd love to hear your thoughts and comments on it is 15, 30lb felt vs ice/water shield over the entire roof etc, one area the roofer didn't think was worth it with architectural shingles for the most part which I appreciated his honesty. Hopefully he is right. Yikes, lastly he didn't really suggest adding a "roof vent, we do have a gable attic fan but I'm wondering if it's really enough and if a ridge vent really might be worth it. Thanks again, great, great job!!
How can Tampko score a 5 on granule loss? A 7 year old Tampko shingle will look like its been pummeled by hail when there has been no storms at all. IKO shingles have the weakest seal strip in the roofing business, 90% of my wind repairs are IKO shingles. OC runs about 93% of a square per 3 bundles and have become a lighter shingle since they have become a big box store staple. CertainTeed Landmarks are built like tanks.
We live in the SW US and GAF is by far number one in sales. However, both Malarkey and PABCO are gaining ground because lots of folks have had a poor experience with GAF. TAMKO is sold here but it is used mostly for commercial construction like apartments as well as new construction. We had a 100 year hail storm in 2016 and literally everybody got a new roof at the exact same time. My neighbor and the guy across the street each bought Class IV GAF Timberline. I bought PABCO Premier 40 which are still on the roof. My neighbor and the guy across the street have since had to replace the GAF Class IV from a few very minor hail storms; they both bought GAF's cheapest Timberline 30 year AR shingle to replace a 3 year old GAF Class IV. How many times do you have to be hit in the head to know it hurts??? . If I had to do it again, I would buy PABCO or Malarkey. Haven't heard anybody complain about either of those. A neighbor that bought ATLAS Class IV in 2016 has also had pretty good luck.
Malarkey is really thin like gaf where pabco has hardly made any changes except granule cut an adhesive all shingles these days after about 90 degrees the seal strip sticks to the plastic on the back of the shingle
Make sure you invest in the Owens Corning DURATION. I used it and is much better than the normal Owens Corning fyi. Lasts longer better wind resistance
@@arcticwo1fee122 Yes, we did and it's a cool roof. Looks great! The old owner put a heavy concrete tile on the roof and we found out our roof wasn't built for tile and could have caused it to collapse.
Hey guy, Great video, lots of valuable information about different roofing products. The rating system was very interesting. I had no idea there were so many things to consider about roofing shingles. I wish I knew all this stuff 2 weeks ago when I had my new roof put onto my home in eastern Ohio. My question to you is how do you like Everest 42 roofing shingles?... I believe the shingles are from Canada. The color was Autumn brown AU2RS1137. Thank you in advance for your time and attention to my question. Have a great day. I enjoyed your video so much. I gave you a thumbs up and I am a subscriber. I can’t wait for the next video. Take care and stay well...
So I just had the CT LANDMARK PRO MAX DEFINITION installed by a reputable roofing contractor. I love the looks and it comes with a great warranty, how would it have performed in the same rating system/test? I watch alot of your videos and have learned alot of great best practices while doing so, THANKS
Thanks for the education. Too bad GAF isn't on your list. It's what I have overhead now. However, a hail storm and Google search brought me here and I think I'll choose either OC or Malarkey for my next roof. One other category you might consider for next time is "Value". Is an upgraded nail zone worth the upgrade in price? Perhaps Tamko may get another star for striking a good balance between cost and quality. I saved $5000 because I chose not to get the sunroof and wheel upgrade option on my truck. It wasn't worth it to me.
Hey my man. Just found your content and you got a new subscriber. I have a roofing company in New York and would love to see that same pull test with a sealed shingle system. I’m an Owens Corning mostly exclusive company but jus trying to use the best product at an affordable cost Thanks again
it's been almost five years now, seeing "someones" driveway covered in granule from every heavy rainfall, i'm thinking their shingles have no life left in them. Thanks for the info. this might come in handy within the next ten years. cheers!
Funny to get this recommend. Just had my roof teared up and replaced. About 17sq with gaf timberland for 9k in the North East. Every tells me i got an amazing deal.
I don’t think you guys should tell the, they got a bad deal as a roofer I hate someone making assumptions before there’s any details how many layers were on roof, was decking in good condition, were there any skylights, etc... I’d say between 7k-10k depending on work performed is fair anyone doing it for less than 6k is either a weekend warrior or starting off in roofing also possibly super broke.
Dimitry, Love your videos and learned alot so far. Live in Northwest Ohio (don't judge me, I'm not from the area),1st time homeowner, have some repairs needed to roof, and looking at replacing shingles on entire roof. Have two quotes for roughly same amount from different experienced contractors/brands. Question is for approx same price, should I put on Altlas Pinnacle pristine (with Signature Select System, no ridge vents) or Certainteed Northgate (with ridge vents and 5 star warranty)? Pinnacle is not class 4, with Northgate is class 4 impact resistant. Your video shows Pinnacle better than Landmark, but is it better than Landmark Pro , Landmark Premium and Northgate? Which manufacturer has better roofing system (underlayments, ice/water protection)? I have areas/valleys that don't get sun in winter... snow accumulated in past, iced and melted and leaked into garage. Discount for impact resistance for me is only $120/yr, not really seeing the benefit. Reviewed severe weather history in my area, and shows mostly penny-quarter sized hail , with winds up to 70 mph...Pinnacle shingles upto 130 mph, while Northgate only warranty up to 110mph (130mph with upgrade). Algae resistance/warranty is important to reduce maintenance down the road. Atlas with lifetime* AR, while Nortgate with only 15 year warranty for AR. Leaning towards Atlas Pinnacle based on your testing, but see benefits to Northhgate's SBS shingles for weather . What else did I miss or need to consider? I'm looking to the best shingle for the value, not cheapest, but not most expensive.
@@RoofingInsights3.0 the only thing I can think of: I would find some way to quantify the sealing strips. (Best guess keep them in an oven for the same amount of time and turn the pull test around.) My thought here is that every time I have trouble with collecting an ITEL sample... It's TAMKO. The damn things bond so well I've taken to making my own shingle seperation tools to get around it.
@@RoofingInsights3.0 The only problem there is that you're testing in reverse... is a hell of a lot more difficult for wind to lift the front lip than someone to pull up on the back of the seem.
Fantastic review. Thank you! I am a first time contractor/builder on our current home build. I am on the search for top grade materials and installation details.
Dmitry, will you please test high end SBS+class 4 rated shingles? A lot of opportunities for sales upgrades here and these products are a LOT better than the standard stuff.
Thank you for this video, I live in Canada and I have to do my roof again after 18 years. The contractor was using the IKO shingles on my roof and I was told that the product has 25 years of warranty, however the shingles on the sunny side started to fall apart already after 18 years. I have contacted IKO and they are offering me the warranty reimbursement. My question is what is the normal lifespan for the shingles in general?
Depends on the market honestly. Weather affects shingles differently. Texas sun destroys, dfw is also one of the highest rated for hail events is 5 to 15 years. 5 if hit with a storm.
Im going to guess that the only shingle that sealed indoors within 1 day was OC. Their sealant is super sticky. I've had a few occasions in the past where a customer adds a tankless water heater or something else a few weeks after roof replacement and when I go back to cut in and slide in the vent, both OC and Atlas are stuck solid and take a little extra effort and care to pull up. Most other brands are well sealed, of course, but come right up with an easy hatchet swipe.
@@justinomora6678 I've only ever used Vista AR from Malarkey but their sealant is great. If I remember correctly, Vista and their other polymer modified shingles were the only shingles around that could be installed below 40°F. This mostly has to do with being polymer modified I'm sure, but they must be doing something right with sealant as well.
This is an outstanding video. However, not sure why you need GAF to respond to you. Wouldn't you just evaluate them against the others independent of their contact? Main reason I came here was to see your opinon on GAF vs Certainteed. Those are the two main brands used in my area by roofers, followed by Owens-Corning.
I live in the Space Coast area of Florida and I am trying to decide between OC Duration and Certainteed Landmark as they are the main brands most contractors in my area install..I like the weight of the Landmark, the warranty of the Duration. This is not an insurance claim roof replacement and it is not my forever home. Thoughts?
Can you recommend a roofer in the Atlanta Ga area? Thank you for the video I am a home owner getting quotes on a new roof and you have been very helpful and I really appreciate it! Nice Work!
Thank you for the shingle evaluation. It has been very helpful as I try to decide which brand and contractor to go with. In the South, shingle streaking from algae is a problem. The Atlas Pinnacle Pristine has a lifetime algae warranty. Some of the others only warranty against streaking for ten years. Why did you not rate resistance to streaking?
Really liked your review. The only thing that would have helped me is if you weighed the different categories. In other words, for example if weight would be weighed 70% while online ratings might be weighed 30%, if could change your final rating.
I have to replace my roof due to Hurricane Laura and the roofers I have spoken to are all installing OC or Certainteed. Should I reach out to manufacturers to find installers of Malarkey or Atlas?
What happens to the overall ranking if you rank them in each category? E.g. if company A outperforms all competition in granule loss they get a 5 but they're on par with everyone else in pull test they might still get a 5. It seems like ranking in each might add weight to certain elements where a company can drastically outperform its competition. As usual, great insight from you. Keep it up!
Thank You For your hard work.. Malarky is not available here. Atlas is.. OC contractor here , I installed my first New atlas shingle last year. Before Atlas Chalet Shingle Failed miserably here.
I have Duration on my roof for almost 11 years. Three hurricanes, Irma, Elsa, and Ian. Elsa was not too powerful, more rain than wind. I have not lost a single shingle, not even during Ian eventhough my home was flooded out by storm surge. My only complain is granule loss. There is tons of it, and you can see the shingle color change due to granule loss. It is so bad that I don't see the roof lasting another 5 years. There is no blistering or hail damage to blame.
Well was going to go with the dynasty, but after watching this I’ll Definitely go with malarkey, especially since they are only made a couple hours away 👍
I will hand it to this gentleman he did cover a lot. He also missed a lot as well. The test appears to be missing many other aspects of the shingle and its performance. I'm familiar with most and have had installed most as well. Region has a lot to do with performance or the lack there of. First question for my friend at Insight is in the weight category. Why are we testing per bundle when we are talking per square weights? Lets redo the test and randomly pick bundles from different pallets of material and maybe different manufacturing dates. 2nd question is in the nail zone category. I see wide zones and I see narrow zones. If we look at the profile of the shingle especially where the shingle is mated or overlapped (where its to be nailed for manufacturers warranty to be valid) we see various overlaps (some small and some actually as wide as the front nail zone which appears). Some manufacturers add a tape strip to help with uplift which contractors are selling as better with high winds? I'm not so sure. Corpus Christi's storm of 2017 didn't discriminate on what shingle was installed. In your opinion Mr. Insight whats a better system? Hand nailed or pneumatically nailed. Maybe give me a few reasons why or why not. What is a pull test supposed to prove again? I see a lot of 3-tab roofs(supposedly inferior) that I'm sure would fail pull tests but are still performing quite well. What are we really testing here? I feel some manufacturers have skewed or manipulated our understanding of what a roofing shingle should do. Maybe this is why GAF didn't respond. Let apologize for that last comment. I'm sorry. Lets move on to count and consistency. Tell me if I'm wrong but why are the manufactures selling squares of material (list above tested)in 3 bundles per square instead of 4. The inconsistency could be eliminated. When I break something into thirds it doesn't work out evenly. Are we educating the public or shoveling ____? Moving on to granule loss. How many months or years in fact has this test been in affect for your results? I hope that opening up a bundle and inspecting what was left in the plastic bag wasn't what you used for this test. Why is this test even relevant? Maybe lets test the granules (Algae version, Solar reflective) themselves or maybe the bonding adhesive. Do all manufacturers use their own components or do they sell to other manufacturers. Lets test the fiberglass mat and the differences each manufacturer uses. Lets test the asphalt and who uses the most filler so they need gimmicks to sell their shingles. I'm sorry again for running my mouth. Why should the consumer pay for an additional warranty? Some manufacturers are going directly to the roofing contractor and offering some sort of ridiculous status as a Super Duper roofer that can offer a Super Duper warranty that the consumer must pay for. Don't the manufacturers believe in their product and think that their standard warranty will hold water? Most consumers move before the warranty is over. Wait did I just figure out what some Roofing manufacturers are BANKING on. Why can't the manufacturers place a warranty on the roofing shingle installed no matter how many occupants? Mr. Insight I appreciate all your dedication and insight. I do feel your service is good and could be better. Keep up the good work! A former roofer.
Iko granular loss is so bad that it’s very slippery and dangerous to install. Gutters are full of granules by the time an install is done. Granules are also what protects your shingles from the sun. So yes it is a relevant thing to test for. Read into how malarkey shingles are made and you will see why it is number one. This test is spot on.

Best of best resource I have ever found online during my 3-day research on shingles! You did an outstanding work! I was struggling among OC Duration, GAF Timberline, and CertainTeed. Now you are the ONLY one giving out non-BS info/data. THANKS!
Thank you so much for great feedback!
Who did you go with?
Yeah curious who did you go with. I'm in the same boat. Need to decide by next Friday lol. Between GAF timberline hdz Owen's corning duration cool and landmark Solaris.
You should include a price category. I feel like that would help a lot when trying to make decisions as a customer.
Pricing is very competitive between these brands.
I've made the decision to switch to CertainTeed Landmark, I've installed Tamko for the past 5 years, this video really helped back up my decision, thank you.
Great to hear! Thanks for sharing!
Very good information, I am a roof consultant and my first goto shingle is always Malarkey, I wasn't surprised by your results. This is a good reminder to my clients who are looking for good roofs not more problems.

Glad it was helpful!
Great info!!!
One point given for all comparisons. Highest priorities for me are:
sealant
Pull test
Nail zone
Granule loss
Warranty
Performance, durability and performance. Thanks
Nice to see confidence in manufacturers who choose to participate.
Indeed
I think a wind test would be fun. I love what you do you inspire me to run my company the best way possible. Which is why i have the best reputation in my area, and keeps us booked months out all year long!
I would like to see wind test too!
They all pass wind test when brand new. Harder to do it when it’s one year on the roof. Because it’s this year test, wind test would be last years lol. But will keep thinking about how to do it
IKO would score a zero in a wind test.
Top 3 make perfect sense, all good quality.
I would be curious to see a real life audit of 5 to 10 year old installs. Sample several as you travel the country to see how climate and age impact performance and appearance. There are clearly fans of various brands represented in the RI community.
As always, great video for contractors and homeowners.
Thanks for feedback
very much appreciate all the effort. Confirmed my decision in an unbiased fashion. Thanks for the straight talk
Thank you for your feedback! Much appreciated
Great Video bud keep it up knowledge is power! Certified Malarky installer here in Tx and we love them Great product and great company!
💯
Awesome thank you! Thanks for comment!
This is really a terrific video . Every salesperson should watch start to finish!
Thank you! We agree, sales guys often don’t have knowledge on products they sell
I would be one of those salespeople! Based on everything I learned OC is my choice because of the high score and overall look. Thanks for all you are sharing!
Very informative video, appreciate your efforts. Even more informative and insightful has been reading all the comments, Thank you all!
Glad it was helpful!
Woo! Thanks for the rating! We need more like this
I just had Corning Duration shingles installed on my bungalow in Canada. I chose Onyx black and they look great. I picked a small piece off the ground when they were Installing and could not break it. I could see the fiberglass in there. Great underlay too. i'm glad I went with the corning.
Thanks for sharing!!! Owens Corning is definitely a good choice for roof shingle!
Thanks for your vids...very informative. More people should watch them before they make uninformed decisions. Its like buying a car..you can't return it. Thanks again.
What a great news for me. I just chose Onyx Black from OC. Hopefully mine looks good too. Thank you
I agree with you on Granule Loss rating. My roof is eleven years old IKO Cambridge Architectural Shingles, I still have to clean the rain gutter twice every year due to high granule loss.
I won't use the product again. I recently found a tap of the shingles at an edge blown away due to high wind.
Very well done and informative. Been using your videos to educate myself before getting the roof done. You can tell that you enjoy your field.
Thank you for generous compliment! Glad you found it informative!
Great video. Need to get my roof redone and your videos are very helpful. Thank you!
Thanks for feedback!!! Let us know if you need help finding contractor, we have plenty of good guys to recommend!!!
Thank you for the video! This coming Tuesday I have one of your guys in your directory
coming out to give me a quote on a sheathing removal and re-roof with O.C Duration.
I'm in Illinois so we'll see how it goes. Thank you for the directory too! Keep educating us.
Thanks for feedback! Let us know how it goes with our contractor!
Get a quote on Certainteed Landmark. They are 100 % better looking and higher quality. 3000 happy customers under our belt that would agree.
"We believe that if the shingle has major problems with the granule loss in the beginning, most likely in the lifetime, it's also going to be the case."
Would you say that granule loss reduces the longevity of a shingle? If so, then from a homeowner's perspective, this is a very important rating category. Perhaps it should be weighted higher than some of the others.
Perhaps you should have more than one overall rating system: one for the shingling company and another for the homeowner. Or maybe add a rating system based on overall durability of the shingle, using the factors that contribute to that.
Thanks again for this video. Very well done.
Yeah, just wrote a comment saying the same before reading this. A weighted system does seem needed.
If manufacturers cant keep granules on shingles immediately after install how can we trust they will stay later? We trust those who made granules to stay out of the box more, just common sense
Excellent well researched video. Covers all the important parameters to assess shingles for value and quality. Awesome job!
Glad it was helpful!
Definitely agree with the Tamko nailing flange they should be a one-star on their nailing flange
Yeah, I think nailing flange and granular lost should be more weighted in the total, as they are big issues that the companies don't end up covering, and you end up fighting with them to get no where.
Excellent review 👏 👌 👍 🙌 Excellent, thanks a lot, if I new or so read this I would be having a piece of mind. I just got Tamco, on my roof 😐, I will get ready for legal action if needed. S.....hit, I'm scared 😱 😨.
Very Informative! Thank you.
As a @malarkeyroofingproducts certifed installer, no surprise to me. No surprise on the Shamko rating either, pure garbage. Great job! Thanks for the effort!
Thanks for feedback! Roofing shingles look similar, but only certified installers who deal with shingles daily can tell the real difference between Malarkey and Tamko. Yet many roofers still will tell you that "all shingles are the same"
GAF's lack of a backbone to be reviewed and compared to other shingle manufacturer's products, automatically takes them out of the running for my re-roof job coming up.
So, take that GAF!!!!
I'm also looking for a Green color, so that knocks others out of the contest too!
Nice! I went from installing OC to Atlas. This was great to see, good job 👍🏼
What made you do the switch? How do you like Atlas Shingles?
21 per
Guess I never paid attention that a good topic because I've went back for one bundles many times
So informative. I want a blue shingle which is very limiting. Malarkey and Atlas are out. I was leaning toward the Iko Dynasty, but now I'm second guessing that. OC Duration might be the winner. Although it seems a lot of roofers are fans of Certainteed. I hate making grown up decisions.
Really informative Dimitri. Especially appreciated the breakdown of the rating system you use.
I don't have a problem with how you did your testing and I have my opinion and I rely on what our roofers say since they install these products every day. They rate the OC Duration way above the Landmark and I'm a CT fan or at least used to be. I was one of the top sellers of the Malarkey products since 1992 in the Denver Front Range area up until 2013 when the contractor I sold for had a negative bias for Malarkey but they were a cheap minded company. The tear test is an interesting test, I would like to see more of that alone and can it be done differently, probably. Wind tunnel tests would be a good video to produce. Thanks for all your effort none the less.
Thank you for great feedback! We have been taking notes and will improve testing in 2021!! New roofing shingle guide is coming in 6 weeks!
Great info, at the end of the day the product is only as good as the installation and 2 roofs with the same shingles can have very different lifespans based on instillation which is always gonna be the wild card!!
True, that’s why finding good contractor is as important as finding good shingle. We can recommend both!!!
@@adebiyiawolaja2241 I've been looking, here as well.. longmont
You reviewed IKO Dynasty, but for the 1 star granule loss section you said it was for Cambridge. Did you just misspeak on that? I recently ok'd my roof to be done next month with IKO Dynasty. The Cambridge line gets a bad rep and I think that blends into why the online reputation is bad for IKO too. Cause it's based on Cambridge. Everything I've read and watched, including some of your prior videos, suggest Dynasty is a pretty solid product. Thanks for taking the time to make videos and pass along information. You really helped a small common homeowner like myself make a decision a few weeks ago!
Last year it was Cambridge with same problem. Dynasty is actually worse. We post numbers on our website
I believe that was a misspeak. I also don't believe the granule loss category makes sense. The excess "carrier" granules in a bundle are overspray and didn't come off the shingle. They were never on there to begin with. The shingles themselves are completely coated. Probably money lost by the manufacturer, but its not granule loss. That can happen, but its after years on the roof. It shows as shiny spots on the roof when so many stones come off, you can see the fiberglass mat.
Malarkey has always preformed well. I have lost 1 Malarkey shingle in 36 years, the winds exceeded 130 mph just after installation. Certainteed is the only shingle i have seen blow off twice in 2 years and both roofs were installed excellently, i had to go back later and hand tab the entire 60 square roof after Certainteed bought the home owners a brand new roof.
Thanks for sharing
Any thoughts on the Malarkey Ecoasis NEX solar shingle?
I have not used this shingle yet. I have used other "solar shingles" . They were a little cooler but the color was frosty and muted. Malarkey only makes shingles and roofing underlayments . I trust them and their products , their tech support is excellent. Thanks for the reply.
@@chrisginoc for what its worth, I had a roofer bring by some full sized shingle samples so I could examine them.. a certainteed, malarky vista and ecoasis.. I tried the roll up test on all of these, rolling them tight, tar side out, like a burrito.. then unrolling and examining how well they held up...the certainteed cracked in alot of places and showed damage when unrolled on the granule side as well as on the black tar side... the ecoasis also cracked when rolled up..not good and Not like any tests ive seen online where they were damage free... lastly, i did the vista..it felt noticeABLY more flexible than the other 2 which seemed similiar in granules and construction but the vista seemed a different animal... more flexible, granules adhered much better and it had the least damage, almost none,when unrolled... In the shingles defense, I did the test in about 70 degree temps...I have a feeling, the online tests where done by leaving the shingles out in the sun to get hot, then folding them...my tests were torturous to those shingles...after rolling up, i stood on them, then unrolled... painful for the roofer to watch and he was impressed with the results... me, less so becuz I was expecting No damage at all... he said any normal asphalt shingle would break under that test.
One of my shingles used is BP Everest
Another excellent video. Congratulations
Thank you sir
Thanks for this very informative video. Very helpful.
You're very welcome!
I called Erie metal roofs.
When they came instead of selling me a metal roof. They brought two guys out to gang up on me, to pressure me into buying there Asphalt roof. The cost for the asphalt roof was almost 10 times as much as my original roof 21years ago. And they were putting a second layer. Without a Tear off!
Awesome job guys!!
Great reviews. Thank you guys.
THANK YOU SOOOO MUCH!!!! 🙌 Your video helped me make my decision on which Company to choose for my roofing job on my home 😁 Excellent Presentation 👏👏👏 Well Done!
Glad I could help!
Review should also include number of color choices
What a great video, not least of which because my two go too products were # 1 and 2 on the list.
Thank you for feedback! Glad you liked it!
Hey you are doing great job educating homeowners and contractors roofer’s, please keep informing the public , many homeowners do not check the product before buying ,
Thanks for your information 👏
Thanks so much for the information, decisions, decisions but your work certainly is making it easier. Thanks so much. We just had a roofer start a quote for us today, he generally goes with Tamko or Atlas, makes me slightly nervous to hear he uses Tamko after seeing your review but maybe it's a 3.7 meal vs the 4.6. If the price is the same I'll probably God willing be going with the Atlas indeed. Thanks so much. He's been doing it for years and mentioned how much grit comes right out of the bags of the GAF and mentioned that he wonders how much stays on the shingle and that it is also dangerous which I believe I heard you mention in either this video or a previous one. Thanks again, great, great stuff. One thing that seems to be a big up seller at least around here and I'd love to hear your thoughts and comments on it is 15, 30lb felt vs ice/water shield over the entire roof etc, one area the roofer didn't think was worth it with architectural shingles for the most part which I appreciated his honesty. Hopefully he is right. Yikes, lastly he didn't really suggest adding a "roof vent, we do have a gable attic fan but I'm wondering if it's really enough and if a ridge vent really might be worth it. Thanks again, great, great job!!
Thanks for feedback, glad you like it!
Ive been roofing for years do not use atlas or tamko,worst shingles out there.Certainteed and Owens Cornings are the best.
I did not read all comments but is there a washing directions on shingles
Thank you for posting this!
We have 2021 guide out!
Love Tamco Heritage. Color selection is beautiful
Wait 5 years. You won't love it anymore
Excellent video.
How can Tampko score a 5 on granule loss? A 7 year old Tampko shingle will look like its been pummeled by hail when there has been no storms at all. IKO shingles have the weakest seal strip in the roofing business, 90% of my wind repairs are IKO shingles. OC runs about 93% of a square per 3 bundles and have become a lighter shingle since they have become a big box store staple. CertainTeed Landmarks are built like tanks.
Great review.
Glad you enjoyed it
We live in the SW US and GAF is by far number one in sales. However, both Malarkey and PABCO are gaining ground because lots of folks have had a poor experience with GAF. TAMKO is sold here but it is used mostly for commercial construction like apartments as well as new construction.
We had a 100 year hail storm in 2016 and literally everybody got a new roof at the exact same time. My neighbor and the guy across the street each bought Class IV GAF Timberline. I bought PABCO Premier 40 which are still on the roof. My neighbor and the guy across the street have since had to replace the GAF Class IV from a few very minor hail storms; they both bought GAF's cheapest Timberline 30 year AR shingle to replace a 3 year old GAF Class IV. How many times do you have to be hit in the head to know it hurts???
. If I had to do it again, I would buy PABCO or Malarkey. Haven't heard anybody complain about either of those. A neighbor that bought ATLAS Class IV in 2016 has also had pretty good luck.
Malarkey is really thin like gaf where pabco has hardly made any changes except granule cut an adhesive all shingles these days after about 90 degrees the seal strip sticks to the plastic on the back of the shingle
TG! I picked the right shingle. We are just doing our roof now with Owen Corning.
Make sure you invest in the Owens Corning DURATION. I used it and is much better than the normal Owens Corning fyi. Lasts longer better wind resistance
@@arcticwo1fee122 Yes, we did and it's a cool roof. Looks great! The old owner put a heavy concrete tile on the roof and we found out our roof wasn't built for tile and could have caused it to collapse.
Nice job man, I had no idea of the science behind to roof shingles. 👍 🔨
Thanks Juan!!!!roofing shingles are not easy to make!
Hey guy,
Great video, lots of valuable information about different roofing products. The rating system was very interesting.
I had no idea there were so many things to consider about roofing shingles. I wish I knew all this stuff 2 weeks ago when I had my new roof put onto my home in eastern Ohio. My question to you is how do you like Everest 42 roofing shingles?... I believe the shingles are from Canada.
The color was Autumn brown AU2RS1137. Thank you in advance for your time and attention to my question. Have a great day.
I enjoyed your video so much. I gave you a thumbs up and I am a subscriber. I can’t wait for the next video.
Take care and stay well...
So I just had the CT LANDMARK PRO MAX DEFINITION installed by a reputable roofing contractor. I love the looks and it comes with a great warranty, how would it have performed in the same rating system/test?
I watch alot of your videos and have learned alot of great best practices while doing so, THANKS
Certainteed are the best shingles I have used, was a 12 year OC installer, been with Certainteed for last 7, and yes they are built like tanks.
Thanks for the education. Too bad GAF isn't on your list. It's what I have overhead now. However, a hail storm and Google search brought me here and I think I'll choose either OC or Malarkey for my next roof. One other category you might consider for next time is "Value". Is an upgraded nail zone worth the upgrade in price? Perhaps Tamko may get another star for striking a good balance between cost and quality. I saved $5000 because I chose not to get the sunroof and wheel upgrade option on my truck. It wasn't worth it to me.
Hey my man. Just found your content and you got a new subscriber. I have a roofing company in New York and would love to see that same pull test with a sealed shingle system. I’m an Owens Corning mostly exclusive company but jus trying to use the best product at an affordable cost
Thanks again
We are trying to figure out how to do it
Excellent show.
Thanks
Great job as usual!
We are in Dallas Monday night, want to meet up?
Roofing Insights I should be able to...I’ll let you know
Good Job!!! I enjoyed the content
Thanks
Outstanding, I had to share your video. What is the best temperature for installing shingles. Approximate range. Thank you very much , Bob
Glad it was helpful! Minimum temperature is 50 degrees. Ideal 60-70.
it's been almost five years now, seeing "someones" driveway covered in granule from every heavy rainfall, i'm thinking their shingles have no life left in them. Thanks for the info. this might come in handy within the next ten years. cheers!
Why didn’t you review Everest?
Thanks - good job
Thank you
Fantastic presentation !!
Have seen that IKO has improved 2021 -2022 granule loss and nail strip.
thank you, very useful information.
Thank you!
We are trying to pick the best brand of shingles/roof! This helps a lot, thank you!! Great content 😻 Also subscribed
Thank you and welcome to the channel!
List seems pretty accurate to me. I'm actually not familiar with your #1 choice though.
Funny to get this recommend. Just had my roof teared up and replaced. About 17sq with gaf timberland for 9k in the North East. Every tells me i got an amazing deal.
17 sq of GAF in North East shouldn't cost more than 7K, IMO
You paid about $530 per square. Going rate for walkable roof is about $300-$450, what city are you in?
@@RoofingInsights3.0 out in long island
Friend in NJ said to overlay his 14 square two story roof was 5k and it was a semi DIY
I don’t think you guys should tell the, they got a bad deal as a roofer I hate someone making assumptions before there’s any details how many layers were on roof, was decking in good condition, were there any skylights, etc... I’d say between 7k-10k depending on work performed is fair anyone doing it for less than 6k is either a weekend warrior or starting off in roofing also possibly super broke.
Dimitry, Love your videos and learned alot so far. Live in Northwest Ohio (don't judge me, I'm not from the area),1st time homeowner, have some repairs needed to roof, and looking at replacing shingles on entire roof. Have two quotes for roughly same amount from different experienced contractors/brands. Question is for approx same price, should I put on Altlas Pinnacle pristine (with Signature Select System, no ridge vents) or Certainteed Northgate (with ridge vents and 5 star warranty)?
Pinnacle is not class 4, with Northgate is class 4 impact resistant. Your video shows Pinnacle better than Landmark, but is it better than Landmark Pro , Landmark Premium and Northgate? Which manufacturer has better roofing system (underlayments, ice/water protection)? I have areas/valleys that don't get sun in winter... snow accumulated in past, iced and melted and leaked into garage.
Discount for impact resistance for me is only $120/yr, not really seeing the benefit. Reviewed severe weather history in my area, and shows mostly penny-quarter sized hail , with winds up to 70 mph...Pinnacle shingles upto 130 mph, while Northgate only warranty up to 110mph (130mph with upgrade). Algae resistance/warranty is important to reduce maintenance down the road. Atlas with lifetime* AR, while Nortgate with only 15 year warranty for AR.
Leaning towards Atlas Pinnacle based on your testing, but see benefits to Northhgate's SBS shingles for weather .
What else did I miss or need to consider? I'm looking to the best shingle for the value, not cheapest, but not most expensive.
I would go with Atlas, dont like Certainteed and their support. Great shingle but I always go with brand that cares more about contractors.
@@RoofingInsights3.0 Appreciate the quick response...Thanks!
Can you have a manufacturer come out after a NEW install and see if the roof would be acceptable for warranty claim?
What’s up with GAF
Very informative thank you i needed that
Glad you can use it.
I wait for this video all year.
Any feedback?
@@RoofingInsights3.0 the only thing I can think of:
I would find some way to quantify the sealing strips. (Best guess keep them in an oven for the same amount of time and turn the pull test around.)
My thought here is that every time I have trouble with collecting an ITEL sample... It's TAMKO. The damn things bond so well I've taken to making my own shingle seperation tools to get around it.
@@RoofingInsights3.0 The only problem there is that you're testing in reverse... is a hell of a lot more difficult for wind to lift the front lip than someone to pull up on the back of the seem.
Fantastic review. Thank you! I am a first time contractor/builder on our current home build. I am on the search for top grade materials and installation details.
Glad it was helpful!
They had issues but did something about it and now they work better by far own Corning
Dmitry, will you please test high end SBS+class 4 rated shingles? A lot of opportunities for sales upgrades here and these products are a LOT better than the standard stuff.
We did one on class 4 shingles already
Atlas Storm Master seems to be the top dog in that one and took the top spot in the national testing and wind rating.
@@travisedwards9983 they are at the top
Thank you for this video, I live in Canada and I have to do my roof again after 18 years. The contractor was using the IKO shingles on my roof and I was told that the product has 25 years of warranty, however the shingles on the sunny side started to fall apart already after 18 years. I have contacted IKO and they are offering me the warranty reimbursement. My question is what is the normal lifespan for the shingles in general?
Depends on the market honestly. Weather affects shingles differently. Texas sun destroys, dfw is also one of the highest rated for hail events is 5 to 15 years. 5 if hit with a storm.
@@norsemenconstruction4606 here you go ua-cam.com/video/vaQKBjClKAA/v-deo.html
Thanks for sharing!
Im going to guess that the only shingle that sealed indoors within 1 day was OC. Their sealant is super sticky. I've had a few occasions in the past where a customer adds a tankless water heater or something else a few weeks after roof replacement and when I go back to cut in and slide in the vent, both OC and Atlas are stuck solid and take a little extra effort and care to pull up. Most other brands are well sealed, of course, but come right up with an easy hatchet swipe.
OC does seal incredibly!!! Even in colder temps. Great shingle all around
I am considering to start using Malarkey Highlander. How is their sealant compare with OC and Atlas?
@@justinomora6678 I've only ever used Vista AR from Malarkey but their sealant is great. If I remember correctly, Vista and their other polymer modified shingles were the only shingles around that could be installed below 40°F. This mostly has to do with being polymer modified I'm sure, but they must be doing something right with sealant as well.
Great Video!
Thank you
This is an outstanding video. However, not sure why you need GAF to respond to you. Wouldn't you just evaluate them against the others independent of their contact? Main reason I came here was to see your opinon on GAF vs Certainteed. Those are the two main brands used in my area by roofers, followed by Owens-Corning.
We already reviewed them
I live in the Space Coast area of Florida and I am trying to decide between OC Duration and Certainteed Landmark as they are the main brands most contractors in my area install..I like the weight of the Landmark, the warranty of the Duration. This is not an insurance claim roof replacement and it is not my forever home. Thoughts?
I would go with Duration
Can you recommend a roofer in the Atlanta Ga area?
Thank you for the video I am a home owner getting quotes on a new roof and you have been very helpful and I really appreciate it! Nice Work!
All our recommendations in Atlanta are in Directorii.com!
Thank you for the shingle evaluation. It has been very helpful as I try to decide which brand and contractor to go with. In the South, shingle streaking from algae is a problem. The Atlas Pinnacle Pristine has a lifetime algae warranty. Some of the others only warranty against streaking for ten years. Why did you not rate resistance to streaking?
it deserves separate video, it is cosmetic, many will argue its not important, but it is very hard to compare
great job
Really liked your review. The only thing that would have helped me is if you weighed the different categories. In other words, for example if weight would be weighed 70% while online ratings might be weighed 30%, if could change your final rating.
I have to replace my roof due to Hurricane Laura and the roofers I have spoken to are all installing OC or Certainteed. Should I reach out to manufacturers to find installers of Malarkey or Atlas?
OC and Certainteed are good, if you are getting good service and quality install you will be ok.
Thanks for the info!
You are welcome, hope it will help with decision
What happens to the overall ranking if you rank them in each category? E.g. if company A outperforms all competition in granule loss they get a 5 but they're on par with everyone else in pull test they might still get a 5. It seems like ranking in each might add weight to certain elements where a company can drastically outperform its competition.
As usual, great insight from you. Keep it up!
Thank you.
If you have to change your roof which would you choose between: GAF, OC Duration or CertainTeed and why?
Nice! GAF calling you out!! the largest roofing manufacturer with the [best] warranty. I hope you hear from them.
We hope so too
Thank You For your hard work.. Malarky is not available here. Atlas is.. OC contractor here , I installed my first New atlas shingle last year. Before Atlas Chalet Shingle Failed miserably here.
Atlas Chalet is a very old story and it did fail, Atlas paid many claims after. Most roofing brands have at least one line that has major issues.
I have Duration on my roof for almost 11 years. Three hurricanes, Irma, Elsa, and Ian. Elsa was not too powerful, more rain than wind. I have not lost a single shingle, not even during Ian eventhough my home was flooded out by storm surge. My only complain is granule loss. There is tons of it, and you can see the shingle color change due to granule loss. It is so bad that I don't see the roof lasting another 5 years. There is no blistering or hail damage to blame.
Well was going to go with the dynasty, but after watching this I’ll Definitely go with malarkey, especially since they are only made a couple hours away 👍
Dynasty is not bad shingle and Malarkey is good brand as well
Roofing Insights I bet they are, but malarkey is somewhat local to me so I gotta support them, especially wild they have quality products
Good video but I would have like to seen the price comparisons that should be part of it
Price is almost identical and not differentiator here
I didn't know that thank you
I will hand it to this gentleman he did cover a lot. He also missed a lot as well. The test appears to be missing many other aspects of the shingle and its performance. I'm familiar with most and have had installed most as well. Region has a lot to do with performance or the lack there of. First question for my friend at Insight is in the weight category. Why are we testing per bundle when we are talking per square weights? Lets redo the test and randomly pick bundles from different pallets of material and maybe different manufacturing dates. 2nd question is in the nail zone category. I see wide zones and I see narrow zones. If we look at the profile of the shingle especially where the shingle is mated or overlapped (where its to be nailed for manufacturers warranty to be valid) we see various overlaps (some small and some actually as wide as the front nail zone which appears). Some manufacturers add a tape strip to help with uplift which contractors are selling as better with high winds? I'm not so sure. Corpus Christi's storm of 2017 didn't discriminate on what shingle was installed. In your opinion Mr. Insight whats a better system? Hand nailed or pneumatically nailed. Maybe give me a few reasons why or why not. What is a pull test supposed to prove again? I see a lot of 3-tab roofs(supposedly inferior) that I'm sure would fail pull tests but are still performing quite well. What are we really testing here? I feel some manufacturers have skewed or manipulated our understanding of what a roofing shingle should do. Maybe this is why GAF didn't respond. Let apologize for that last comment. I'm sorry. Lets move on to count and consistency. Tell me if I'm wrong but why are the manufactures selling squares of material (list above tested)in 3 bundles per square instead of 4. The inconsistency could be eliminated. When I break something into thirds it doesn't work out evenly. Are we educating the public or shoveling ____? Moving on to granule loss. How many months or years in fact has this test been in affect for your results? I hope that opening up a bundle and inspecting what was left in the plastic bag wasn't what you used for this test. Why is this test even relevant? Maybe lets test the granules (Algae version, Solar reflective) themselves or maybe the bonding adhesive. Do all manufacturers use their own components or do they sell to other manufacturers. Lets test the fiberglass mat and the differences each manufacturer uses. Lets test the asphalt and who uses the most filler so they need gimmicks to sell their shingles. I'm sorry again for running my mouth. Why should the consumer pay for an additional warranty? Some manufacturers are going directly to the roofing contractor and offering some sort of ridiculous status as a Super Duper roofer that can offer a Super Duper warranty that the consumer must pay for. Don't the manufacturers believe in their product and think that their standard warranty will hold water? Most consumers move before the warranty is over. Wait did I just figure out what some Roofing manufacturers are BANKING on. Why can't the manufacturers place a warranty on the roofing shingle installed no matter how many occupants? Mr. Insight I appreciate all your dedication and insight. I do feel your service is good and could be better. Keep up the good work! A former roofer.
Thanks for detailed feedback!!! Notes are taken!!!
Iko granular loss is so bad that it’s very slippery and dangerous to install. Gutters are full of granules by the time an install is done. Granules are also what protects your shingles from the sun. So yes it is a relevant thing to test for. Read into how malarkey shingles are made and you will see why it is number one. This test is spot on.
