well...not exactly. You may be a good roofing "salesman" but i doubt you possess a roofing license. I have 25+ years in roofing as a state and city licensed, certified contractor. Felt is, principally, a vapor barrier NOT waterproofing. And that is why it is technically classified as such. You will (I promise) blast 1000s of holes through your fancy "waterprooof" felt when you nail your shingles through it. Still a "waterproof barrier"? Of course it isn't and you know it. The actual origin of felt usage is interesting - you should read about it but it had nothing to do with being a part of a "waterproof roof system" - suffice to say for decades roofers didn't even install it (I've torn off roofs with no felt and they were perfectly fine for the 30 year shingle service life). Felt was made for the homeowner to "dry-in" his roof when a father/son DIY'd it because it took them weeks - and it was a common thing back in early 1900s America. Basically - felt was a tarp but then the manufactures realized they could get everyone to "value-add" to the job and it became taboo not to install felt when everyone knew that in most cases, it was unnecessary. Kinda like the way "government" has become "necessary". If you install shingles properly, the felt is superfluous. Felt is rarely actually necessary - says so in most shingle application manuals in fact it used to not even be a warranty requirement until they realized they could force you to buy/use "their" branded product and spend even more on fancy stuff that was totally unnecessary. Yes, below 4/12 pitch you need to provide more than a vapor barrier because in the absolute worst storms, it is possible for a shingle system to be defeated but it is still rare even below that pitch and most homes are 4 or better. But these fancy peel n stick ice and water shields are BS and not necessary. You know and i know that the manufacturers are just creating expensive fancy products so you make your jobs "sound" better than the other guys and that's all fine - EXCEPT when you guys go and start saying that roofers are "cutting corners" by not installing this. No - they're saving their customer's money by not installing it. A shady roofer will say he is installing something when he isn't. A pro will not charge you for - and not install - something you don't need because he knows his roof does not need it in order not to leak - just like his dad's and his grandad's didn't need it. Bottom line is that there certainly all sorts of roof scenarios and sometimes you need something extra but any real licensed roofer can explain those. But don't run around trying to make other roofers out to be the bad guy, when you're just installing crap your customer's don't even need - because you might just get called out by a 3rd generation certified master. PS: I've seen installs you posted on YT; standard ridge on a dimensional? overspray and wrong paint code for flashing? one inch exposure at the eves? valley metal on normal pitch? all mistakes. Monkey see, monkey doo - someone taught you wrong.
Hi Dimitry - if I am having new shingles installed should the underlayment be from the same manufacturer? I think you mentioned in one of your videos ( Best Roofing Shingles?) that a consumer should check to make sure the accessories are the same so it doesn't cancel/compromise the warranty. If it doesn't void the warranty, I am looking to install Owen Corning TruDefinition Duration - what would be the best ice & water shield underlayment?
@@mrwhiteinca interesting, right now everyone wants to build the perfect house but is difficult to find someone that really knows about it.
So far I've learned the following (but I guess some of this information is wrong)
1.that the shingle needs to be light colored and sealed with clear acrylic coating
2. That the felt has to be waterproof
3. That a radiant barrier is needed underneath the plywood
4. That's mandatory to insulate and seal the inside of the roof with spray foam
5. That a vapor barrier and/or vapor retarder is needed in the inside as a final layer before the ceiling installation
6. Roof venting is always a must no matter the layers of insulation
7. Building an attic helps the owner to be aware of any damage
8. The roof framing with metal is better than wood
I'm not a professional as you can tell, but the above is what the so called experts teach online, maybe not everything is wrong.
@@mrwhiteinca I'm just trying to find out, if it's ok to use the tar paper under my metal panels to help prevent condensation inside my trailer instead of that expensive stuff?? And NO ONE will answer my question. I'm starting to think NO ONE KNOWS!! 🙄
@@eduardomaradiaga5868 the so called experts online, can not give me a simple direct yes or no answer as to weather or not, I can or can not, use the tar paper under metal panels to help prevent condensation inside my metal trailer roof. So I really don't think the so called experts online, know any more than the people that get online looking for a direct and honest answer!! 🙄
Thank you, I am having a roof installed and your video definitely educated me on what to get. Keep up the good work! --- Fred
Used Resito eves protec as first underlay and then a membrane underlay.
The eave trim is over the resisto and the membrane is overlapping the eave trim.
The Resisto acts to seal screws and do it's normal job.
I used a GE product to adhere the 3 inches of membrane at the eve trim.
Used Butyl tape for all seams and Gable trim.
Including valleys.
Bought large closures for the ridge cap.
Great video. Getting a new roof this summer and now I know what to ask for and when they talk about underlayment, I understand now. Very helpful and informative. Thank you, Mr Simmons.
Unless your in Alaska or a state that is minus 10 or colder winters lots of snow ect , you do not need to waste money on this stuff. Regular 30 pound felt has worked since the 1950s. This is all profit sales pitch for the contract
No problem! Glad I could help!
, would you recommend 40 # felt? I live in NW Florida, and it is very hot.
Awesome. Never thought of using base as an underlayment. Thanks.
Thank you for time stamps 🙏🙏🙏
Love the diamonds deck and interwrap
Thanks for sharing and to the point we are going to be putting a tin roof on our roof and would love to see a video on your high temp ice and water shield in I’m looking forward to seeing one of your videos
I was look for a simple was and cheep way to seal up a roof that I got to remove peel and stick and I heard you asking about the fiber glass under lay ment I have used for my torch down roof cover over &I used fiberglass under lament on a motel roof over ,the roof was the old style rubber mat style small pitch flat roof, it was wrong down but still in good shape it just need a top cover I used some cold process adhesive and used the fiberglass felt or under lay ment ,for the top cap ,the fiberglass mixed in whit the felt gives the rool a dark gray look with the white fiberglass , the tools are 36" wide so when I roofed and rolled the rool out over the adhesive ,I went over with a 30" sod roller then my over lap was 16 "All they way thru the roof were 16 " joints there a small pitch on the roof but all in all the fiberglass under lay ment is hela strong and seals what ever you use it on !!
Thank you for a very informative video
Very informative!!
Great info, subscribed
Learned a lot in 6 minutes. Thank you. Would this be the same for what is used for roofs that have tile installed?
did my whole roof underlayment in ice and water, in case i ever do solar ... great vid
I have shingled a few hundred roofs in my time, taken off shingles 30 plus years old tar paper under them was in amazing condition could have reused it(but did not) the huge benefit of the new underlay is the strength , it will not tear off the roof on a windy day if installed correct, tar paper tends to tear off. My experience.
Another issue with tar paper, is that if it gets water on it before the shingles go down, it gets all warped and bubbly.
Just had a new roof put on, pretty sure with adhesiive rain and ice underlay. Subcontractors took a shortcut and put it over bad wood on the garage. I can see the underlayment through 2 holes. What kind of repair is that going to involve - whole side of garage, bad section only? Just trying to be prepared if they BS me.
@@woodstream6137did you pay them to repair?
@@brianmcdowell7377 warranty covers it.
We use safeguard 30 it’s a hybrid underpayment it’s pretty good but it’s experience, it runs about $94.00 a roll and it covers 449sq ft.
Great information
Great video
Good info, thanks for the video!
Glad it was helpful!
We need to replace the roofing on a relatively small gazebo. We need 8 triangles and have available standard asphalt shingles. Trying to figure out the best way to tackle this small project. We are older but in decent shape to get up and off of ladders. The center hole is not large enough to get up into, so have to approach from the edges.
Licensed since 85…I tried the synthetic & liked them- but-a friend had “numerous” leaks with synthetic & determined that the synthetic was tearing at the nail, the synthetic didn’t hug the roof adequately & put to much pressure around the nail…I went back to Astm #30- 2 layers if the roof is a rock to composition conversation or under 4/12 pitch- always use peel & stick in valleys..If I’m going over 1x6’s some times I’ll upgrade to modified felt..
the issue is using just nails and not nails or staples with plastic caps as per specification on the install instructions from most, if not all the manufacturers
Been using synthetic for about 5 years, we've never had a single leak or tearing. Some synthetics are thicker than others, such as GAF's Felt Buster Vs their Tigerpaw. when using the Felt Buster, you need to pull it tight as you're rolling and Stapling with the Stinger caps at the same time.
It is a learning curve going from tar paper to synthetic
I just bought Fortress by roofing products. It is a 3 ft tall roll made of asphalt covered with a plastic cover easy to remove.
We are using storm guard in SW Fla on the sheathing then probably rolled rubber or shingles on top
That was interesting. We are manufacturing and selling those sticker type membranes for underlay along with the granulated on top for slow slope roof.
My house was built in 1980 and has a concrete tile roof and I'm not the original owner. However, the builders made the roof without any subroof ... just flat 1x6 horizontal slats under the tiles. You can easily see daylight looking out the attic space. Having my roof replaced because a couple edge tiles have broken off. Just deciding whether I want (concrete vs. ceramic) tiles or composite/asphalt roof (with a completely added subroof). Your recommendations? I live in California's central valley where we get winter lows in the 20's F and summer highs in the 110s. This video is helpful. Thanks!
That' was the standard for tile roofs back then! Called skip sheathing.
That one spot where you show the video of it raining and it looks like the problem I’m having, I just got new gutters and when it’s pouring out it looks like the water is coming out from the eaves where it meets the gutter
what do you think about Certain Teed Diamond Deck Underlayment????
I moved to Oklahoma City a few years ago and learned a new term: "ice damming".
Lately, we have also had some hail damage. Not enough to replace the roof yet but I can tell it's coming.
I intend my next roof to be ice and water shield under stone coated metal shingles.
Do you have a video comparing high temp ice and water shield to other underlayments?
Nice video any underlayment for torch-down roofing installation?
Use #28 fiberglass base, it doesn’t hurt giving it less exposure for flame protection…Dibiten is the best torch down period..they use imported crushed slate flakes from Europe..It’s not cool roof compliant in California but a cool roof coating can be applied once finished..Make sure there is an overflow on all seams and side laps, if not get the roofer back…in 30 plus years of installing 2 roofs a week I’ve yet to have one wear out…
Dmitry explain the importance of putting synthetic underlayment over ice and water shield so many don't and when we go back to tear off shingles their melted together and will not come off it's uninspected and crucial to reroofing a home
This was interesting. My wife spends her days on Instagram, I watch videos on roofing and other interesting stuff.
I watch beheading videos from the middle east
you have a broken wife... time to replace
social media is cancer
@@notimportant3686 😂
@@notimportant3686 my exact thought. What’s she looking at
Great information. I'm building new home and only have synthetic felt on right now. Heavy rain today and spotted some leaks. Spoke to the builder who check it out but is this common on a roof that doesn't have shingles on?
The entire point of felt is so your roof doesn’t leak before the shingles go on..If your roof is leaking as a result of the pipe flashing collar not being sealed or some other applicational error that’s not the underpayment fault but if the felt is tearing at the shank of the nail that’s the underpayment fault..In 40 years of roofing thousands of homes #30 ASTM felt has never been an issue..
CertainTeed makes the fiberglass felt paper. It's banded as Roofer Select. I hate using it, leaves me itchy for a day or two so where long sleeves and Pants if you're not use to handling it.
Don't get excited either, it tears just as easily as 15 & 30 ibs paper and if it gets rained on before you install, it wrinkles up and takes forever to dry flat again
Never going back to it since we've been bringing in Felt Buster and Tigerpaw from GAF, I couldn't imagine going back to Tar paper
Hey, how about those radiant barrier capability underlayment? Like Low-E Thermasheet. Looking forward a review on that...
Firestone makes some awesome rubberized underlayment. Its really expensive, but great stuff
And then you went on to describe base sheet...awesome stuff
We used the peel and stick flintastic stuff on our treehouse roof. It's confusing because as a non roofer I was thinking for a minute I had to put felt on tope of the flintastic underlayment. ~~ I guess I don't have to. It's not a crucial job and the hexagonal treehouse is open on two sides, but we still want a decent roof.
Good stuff!
New roof installed. Found out subcontractors didn't remove bad wood over part of garage. It has ridge venting and should have used some sort of adhesive underlayment like rain and ice. Went into the loft and you could see the underlayment through 2 softball size holes in the wood. Do they need to redo the whole side of the garage or can the rain and ice be merged with existing work so only the bad section needs replaced?
We're in need of a waterproof underlayment for our flat roof on top of the car port. We will also be putting an outdoor carpet on top of it that will be glued down. Do you have any suggestions for us ? Thank you for your response. Diane MacKenzie
Will the synthetic underlayment work for concrete storm shelters?
It would be good to talk about code requirements for ice barriers and where they are required to be used. I would also like to see you go over the correct way to install a drip edge on the eave and gable ends of the roof. A lot of roofers do not understand the concept of protecting a roof from back up especially if you have gutters. The membrane is taken over the edge and down behind the drip. Then the drip is installed followed by flashing tape to seal the leading edge of the drip.
Screw code. I just want my half mil dollar houses to last.
@@manictiger That is the very purpose of codes-with out them customers would complain consistently and demand something done with codes people complain they have to follow them-you can't win
@@jakefalasca1561
Right, but I tend to focus on how things are done by the pros first and what's "to code" second. Usually they line up, of course.
@@manictiger exactly I went from code to common sense and knowledge I gained from feeding shingles to installing them
@@manictiger Then watch the Build Show ha ha ha
Would like to see a review on ridge vent systems. I have a Cobra ridge vent. With the size of the vent slots It lets in tons of seeds and debre into the attic. Is there anything that can be done with these to prevent the debre infiltration?
Cut long strips of aluminum window screening and staple that down, then put the ridge venting down
Great info thx!! Question: is it same considerations for clay flat-tile roof? I was told that felt might be better for my tile roof because of breathability, but everyone I look incl your vid synthetic is more recommended.
do i put something between the peel and stick and the asphalt shingles ? Also do i put paper or synthetics between roof and peel and stick?
Thanks for your video on underlayment. I live in CT. and am having leaks over sunroom.I had solar panels installed on a roof with a 2/12 pitch. Should the solar Co. have recommended and or checked for an underlayment before installing my panels?
Absolutely, they should have inspected the roof before the solar install. I had solar installed one year ago and the installer did a thorough inspection on my concrete tile roof beforehand and also provided a roof penetration warranty for 24 months. I checked in the attic after the first rain and saw no evidence of any leaks. Check your contract for a similar roof penetration warranty. Good luck.
What is your opinion of Roof Max and Roof Renew rejuvination? Does it work?
Can I use the synthetic underlayment and top it off with the top cap of the brand of roll roofing you showed in this video..or do I have to get the base layer to it?
I have the underlayment that was like the first one you talked about…i have a small hole in it and want to know if I could use the water and ice self sticky underlayment to go over the hole of the torn underlayment to seal it and put the tile back on it?
I used zip system on my roof. Installing Epdm over it . The adhesive doesn’t stick to liquid flash and flashing tape. Going to try 3M™ Hi-Strength 90 which Huber says sticks to their product. Was considering blue skin in my scupper trough but will have to test this adhesive on that as well.
Unfortunately you used the wrong product. If you are using EDPM a ZIP System sheathing is not compatible. Also ZIP System sheathing should be used on a roof with a slope greater than 2/12. I hope this helps.
@@captainmo3064 Yes you are correct however . I feel confident it is completely sealed. Flashing and liquid flashing around all edges . No seams in the membrane. The 5/8ths zip roof sheathing was completely sealed as well with no leaks for about a month of storms before I got the membrane down.
I have a low pitch roof that has a granulated rolled roof here inHot Humid Florida. I want to upgrade to a shingled roof, but I don't want to remove the existing roof.
My question is, what type of underlayment can I use over the rolled roof?
Best underlayment for flat roof .We do get hot during summer ?
My 6 yr old roof bit the dust in Hurricane Ian in FL. My insurance adjuster said it was in good shape. I lost all the cap shingles and more. An independent public adjuster told me I need a new roof that the gutters are FULL of gravel or whatever you call it to not clean it out it’s evidence. We had 8 hrs of 150 mph winds for 8 solid hours. I’m trying to educate myself but so confused. I want to know what questions to ask when choosing a roofer. Probably 1 in 3-5 houses here are tarped or have a new roof. 😮
Can the "Base sheet" (at 4:50 on this video) be used as a stand alone underlayment in Arizona with concrete tile?
what is the brand of of high temp ice and water underlayment do you recommend?
Thank You Sir 👍
thanks for this educational video, author talked about ice and water shield which it directly stick to the decking then put the regular underlayment over it, but at time 3:35 why the ice and water shield put on top on the regular underlayment ? or it doesn't really matter the order. anyone know why ? thanks
What about best value and price ? What about albedo for energy efficiency?
I purchased a new enclosed trailer and underneath it is OSB board that would rot over time. I'm wondering if this sticky roofing membrane would work under there??
If I do any really steep roofs I like to use rhino synthetic underlay, it’s nice and grippy to walk on and shingles don’t slide on it as much
If I had extra blueskin SA, could I use that as an underlayment for a shed? It being slippery isn’t a big deal, it’s a small shed. I’m just wondering more about the shingles adhering. Actually they get nailed so it shouldn’t matter…. Right?? Lol
@@thefinaldispatch 💯 would be fine.. don’t even really need any underlayment especially for a shed but if you have extra blue skin forsure use it!

Thoughts on tiger paw?
what underlayment do you recommend in Florida?
I live in El Paso TX (79821) Its Very Sunny, Very HOT and Dry. Is there a thermal barrier that we can install between the underlayment and the Asphalt shingle?
Is doing the whole roof in base shield worth the cost over synthetic?
Thoughts on grip rite?
I had to use a red rosin paper in OK for a few gov jobs. It stands apart visually compared to old tar felt. But inferior to any synthetic
Red rosin on a roof job…😱🤯.
Can i use the synthetic underlayment just by itself? I watch a video where a guy said to place and ice and water shield under the Synthetic underlayment. is it necessary or just an added layer of protection? Thank you for the info.
Whats your take on Titanium UDL 25, 30, and 50? Synthetic underlayment. Also Titanium PSU 30 Ice and water shield?
Where can I find the current pricing per roll for this Malarkey Arctic Seal underlayment? Just had a new roof installed, and the contractor should have put the Malarkey Arctic Seal, but instead used GAF Feltbuster! This seems like a breach of contract. Would I have recourse to make the roofer do my roof again to put the Arctic Seal underlayment? I ordered the Malarkey Vista shingles too, and now I need to confirm those are the shingles on my roof (they had brought the Highlander shingles the day before, and I told them about the error).
💯What's the best options for under a metal roof in the midwest with snowfalls? Thanks for tips!

i used the "fiber glass paper" but it was a base sheet for cold glued bitumen roof and also had mineral grit so it was like a roll of sand paper if this is what you was talking about ?
Would you recommend Ice & Water vs Peel & Stick?
underlayment serves 3 purposes ...temporary roof until the roof is installed ....moisture barrier and prevents shingles from sticking to the decking
We use an ice and water shield that has fiberglass coating on top. Is that the same material that you showed? I think it was the high temp ice and water shield.
Any cons to using ice & water on entire roof decking? I've read its not recommended because it doesn't allow roof to breath but by code it us required on bottom edges and flashing tape is required on plywood seams so I don't understand how that is any different! Thanks
And seen fiberglass nailed down with cap sheet over top of it with only the drippage being nailed down from peeling the Band-Aid off the entire roof
I think base sheet and cap sheet are really good way to go until you have to remove it and replace a piece of plywood down the road
thanks for the info I live in a very hot place and want a better than tar paper with a tile roof. I have been wondering about a peel and stick. Not sure what's a good product. I was looking at roofnado or titanium or tech wrap, even tyvek what are your thoughts
Let's think about a re-shingle job on an existing house. What is the main importance or purpose of the underlayment? It' not put on primarily as a secondary leak stopper. It's put on because unless you are putting new shingles over the old, it is YOUR ONLY leak stopper, until the roof is finished.
I've heard of some underlayments that won't even hold water. What sense is that?
Is grace the best ice and water shield?
Thanks RI. Can you tell us more about the moisture permability of the underlayments?For example felt/tar paper will allow moisture to escape. If water vapor is not allowed to escape wont the wood sheathing eventually rot? Thats what I worry about with these new plastic underlayments.
I know that Malarkey makes a synthetic underlayment that is breathable. It is their premium grade underlayment. Find it on their website. Maybe others do too, IDK.
Please suggest which of these underlayment combination is best for Florida?
-1 layer of weather lock G Granulated Ice and water and 1 layer of Rhino synthetic
-2 layers of RhinoRoof synthetic underlayment and WeatherLock Specialty Tile and Metal for the high temp water barrier at all valleys, along walls, and around roof penetrations.
-1 layer of RhinoRoof® Granulated Self-Adhered Underlayment
Actually, the best in Florida at this moment will be SharkSkin Ultra laid at 3/4 exposure with a 6" grid spacing using 1-1/4" ring shank nails. System is Florida approved @ -210 psf and carries a 50 year limited manufacturer warranty. Oh and exposure is 1 year.....Ain't gonna find nothing better than that!
Is ploystick tu max a good option for tile roof in california?
Good video. I would think/like to have it explained in more detail about felt and synthetic felt why its required. Most people think vapor barrier and it is a fire code issue (slow down the burn if there is a fire) synthetic taking the place of both a vapor barrier and fire code vs felt just more so on the fire code. We use the HT (high temp) primarily only on metal roofing, some of the Best in my opinion is the Shark Skin underlayment
What do
You like about shark skin?
I’ve never heard of shark skin! It sounds awesome though, what makes it so special?
@@roofingtips We have only used it when doing metal roofing. When doing long panels you want the best grip on your feet I just feel as its not as slick as grace underlayment (who also makes a good HT ice shield) Iv never used it for anything else but the surface is easy and safe to work on and it provides a really good barrier.
@roofing insights
SharkSkin is the best!
Ive been researching this for months and can't get a solid answer. 2x6 fiberglass, conditioned attic, in NV zone5, (-10f with snow to 115f), high wind application. I want to install a metal roof with an air gap. my only question is, is it safe to install peel and stick (zero perm) onto entire roof deck? Im concerned that interior moisture could start adding up in the fiberglass. I like peel and stick for the benefit of sealing around penetrations.
I’d like to see a video of real world testing of underlayment. Putting 15# felt paper, 30# felt paper, synthetic paper and ice and water down then soak it with artificial rain aka a hose and see how protective it is and for how long. That’s a video I’d give a thumbs up to.
When the installer is preforming a demo with a synthetic underlayment. The roofers have to remove the shingles but not with pitch forks. That’s like picking up a vacuum sealed potatoes with a folk. For lack of a better analogy. They have to remove the pins from each place they were secure. safe to say the synthetic IS superior over felt. But I would be curious about. Is ice and water barrier cost effectiveness and how do you make the customers experience exclusive.
Great question 👍 its extremely hot in Texas. I’ll tell you what.
@@incubedinsight4940 that’s not true at all. Old synthetic falls apart and crumbles and a fork is easy to use
Recently I had to purchase new insurance for my house. The new company had me pay for a four-point inspection, $150.00. The inspector spent some time on my roof. He asked who put the roof on. I told him the roofing company's name and showed him all the paperwork and the permit. He seemed to be very impressed with the quality of the materials, especially the underlayment and workmanship. I also showed him a scrap piece of the underlayment material. At this point, he told me that I could expect to get a lower price on my new house insurance.
Interesting. I just installed a “top of the line” 50 year roof and the price of my insurance went UP, because the replacement cost of the new fancy roof is significantly more than the replacement cost of my old 20 year 3-tab shingle roof.
I expected a discount like you got, but it made sense from one perspective: If the house burns down it will cost the insurance company more to replace it.
I wonder how/why your insurance company approaches it differently?
How do you seal all the nail holes you make when you fasten the syntheic underlayment down? Doesnt seem like the seal would be as good as the one on the rolls with asphalt in them.
what is the preferred underlayment (vapor barrier) for a tpo roof?
What about synthetic underlayment like FT Platinum or Epilay Platinum?
How about the Therma Sheet underlayment?? My company uses it and we have great success
What area of the US?
Hello
thanks for posting this video
I'm having a roof installed on a flat roof in Brooklyn NY (house was built in 1847). The roofers are putting down a 2 inch ISO rigid insulation board then covering it with an ice barrier,, the roofing will go over that.The ice barrier has an adhesive on the back of it. They told me they are going to screw or nail down the ice barrier on top of the ISO insulation.
My question ... Is that OK? Won't the holes from the nails or screws cause leaks if water gets under the roofing. Please let me know what you think. Thanks
Any answers out there?
What about cost comparisons for all these underlayments? The paper-type (first one) is old school, and, a home owner, I would prefer something better! Thank you for vid! Very helpful to know about this, so that people can see if contractors/roofs would do a good job both at labor AND materials they charge the customers!
I'm an idiot at roofing and I Don't like ice and water barrier from Owens cornering. I do love their synthetic felt. I can tell you the synthetic felt held with cap nail until 60mph winds. The ice and water completely held in those wind without me really worrying about it much.
The reason I don't like the ice and water is if the nails are not fully sank it will protrude through your intended barrier. It says to use a fifty-pound roller I used a ten and it was a mess. Only one side will have ice and water barrier the other side I'm doing two layers of synthetic felt instead. Time will tell if it's a good idea or not
And I can give you the numbers on the current day cost on both
268 ft of like 4ft wide synthetic felt costs is $99.99 or less
Ice and water 70 ft about 4ft wide was $99.99 or less

0utstanding!👍 What's your thoughts on GAF Tiger Paw Synthetic Underlayment?🙏👀🙏
Look up safeguard 30..... hybrid, part polymer part asphalt, and it’s no joke, you can walk a 12/12 no problem. Just did one with it.
Their website claims it’s the best of both worlds. There’s an endless supply of one-off underlayment products. Cool stuff
I have a question I have Rhino u2 synthetic paper. And I was wondering if you can tar over Roofing paper I want to do it to my camper. Can you do it with the black Roofing tar or that white silicone Roofing sealant like tar that you buy at Lowe's or Home Depot. My answer is can it be done would it hurt would it help what is your opinion. What I was going to do is put the tar down and as I'm mopping tar on my roof roll out the Roofing paper so it sticks. Then after that go back an tar the top of the paper?!?!?!? Now remember this is for my camper in my camper has a sheet metal roof
High temp ice and water shield will that stick onto the asphalt shingles? Asking because I have a 20 x 20 room that has live 4 different leaks cause it's a flat roof on that section. I am gonna put a metal roof on that section of the roof over the shingles. Would you consider putting this high temp product over shingles along with pearlands and then the metal roof? Or how would be the best way to do it on a budget any help is greatly appreciated
