You should have measured the backside of that sheeting behind the black and behind the Puter to see what the temperature was behind each color.
Five to 6 degree difference doesn't seem like much, but it really is. The difference between white cement tile roof and a terracotta colored roof is about 15 degrees! Again, it doesn't seem like mutch, but it is.
It may seem like a small temperature difference if it's 5 or 15° but you got to realize that that is a consistent temperature difference throughout the day it compounds and adds to quite a bit of extra heat in the home
@patrickzavas very true
The real question is what would the temp be in the attic.
That is a great question. This is just a surface test. I’d love to have some kind of attic test where I could control the variables.
@@roofingtips Cool! Can’t wait to see if you do. It’ll be interesting because I have a dark roof now and I was always under the assumption the darker the color. The more heated the attic would be inside.
I have recorded temps in the attic in Florida 155
I just got a brand new GAF roof.. charcoal, the darkest there is. I like
@justaskmike4602 that is insanely hot!
I’m a roofer in Oklahoma.
There’s zero difference in attic temperature from a white roof to a black roof.
The owner of a the white roof just has extremely bad taste. *That’s the difference*
I've done test on this with roofs and attics and the color really as no different on single ply roofs. But when you have multiple layers what happens is it take alot longer for the roof and attic to cool after the sun goes down. 25+ year's experience in East Bay Area California.
Thanks for the comment
That’s exactly right
It’s mostly alol about ventilation.
If you want to mitigate attic temperature further putting down a radiant barrier under the synthetic felt application would be the first step followed by spray foam.
But what do we know? Let them have an ugly white roof.
I live in Florida it’s very hot am about to change my roof are you saying the black and dark grey colors make the house hotter ?
i have the same shingles in dark brown....i just painted them white...i took a temp reading...in full sun at 81 degrees the brown shingle was 150 degrees... right beside that reading i had painted one coat of white roof coating, by Lanco the painted shingle was 118 degrees, 32 degree difference with just one coat of paint... big difference in heat transfer to the living areas. I spent $620 for a 1500 sq ft house 40 gal total for 2 coats of paint citrus county Florida, house is in full sun all day...I should have painted the roof years ago, I didnt know it would make such a difference
That’s wild! I have heard of roof paint, but never actually seen it done. Is it designed for shingles specifically?
I have measured black shingles (CT Moire Black) at 199 when 100 degrees temp. Houston tx.
That is insane
@@roofingtips Black synthetic felt hit 203 that day!
Pretty good experiment. Comparing a light gray shingle with a black shingle would be interesting to see the diff
I’ve got another comparison coming up soon that will be a cool rated shingle, compared to a standard shingle
Parents went to black on a single story house and what a mistake! Had to add more roof vents and insulation in attic! Neighbors next door did the same and was just like a parking lot added next door outside my bedroom window!!!
Like I said in the video, any roof needs to have good ventilation, otherwise it’ll cook!
Try a white shingle. Try wearing a black t-shirt in the sun and then try a white t-shirt. Hugh difference. I just had a white shingled roof installed compared to a dark brown shingle and what a difference. Much cooler in the house.
This is very good information. I ordered Onyx Black shingles. Thank you!🖤
I’m glad it helped you! Onyx black is a nice design!
Thinking of the onyx black too. You like it?
@@kristinwilliams9779 yesss I love it
you should do a comparison with the solar reflective shingles too
That’s a great idea. Thank you. Stand by!
This should be measured on 2 different stands/plywood boards. Then you'll see
Wish you would have put up white shingles because I am doing research and comparing. But I can definitely appreciate the research.
the white would be about 32 degrees cooler...I tested it in Florida at 1 pm 81 degrees dark brown shingle 150 ,, shingle right beside it with one coat of white paint was 118 degrees
@josephfitch1 check out one of my newest shorts about the white roof coating I just did. It was nearly 40 degrees cooler. I believe you man. It’s crazy. How do you keep it clean?
Im curious to know if adding spray foam insulation to the back of one of the roof material colors would actually increases the heat of the shingles.
What about an even lighter colored shingle? Like light brown color? Should be even cooler right?
Slightly, but it doesn’t make enough of a difference to really justify picking a color simply for the cooler temps. The moral of this video is pick the color you like and make sure you have good ventilation.
Hold on…are you saying that you believe brown is lighter on the color wheel, then gray???? Let me guess, you have a masters degree from Devry?
🧑🏻🎓
But what about the light’s color like Shasta White or Amber?
Stand by! I will be shooting a video this summer with some new “cool” colors by Atlas
Too ugly to test.
I would have preferred you to have used more contrasting colors a much light color than the pewter. I used to have charcoal colored shingles and but switched to a sand color and it seems to me cooler by electric bill.
I wanted to use a very popular color. Sand is a pinnacle Sun color, so it’s designed to be cooler by around 20%.
My goal was to use two shingles from the same class or model and compare them.
If you have ridge vent and soffit intake at the correct ratio, there's no need for any other kind of ventilation. In fact, if you add any static vents in addition to ridge vent it will work against the Venturi effect. This would apply to powered vents or solar vents when they're not running. One type (static, solar, powered, whirly bird etc.) or the other (ridge vent) but not both 👍
But ridge vent is SO ugly.
Nothing beats good rear facing box vents for aesthetics and performance
@@h2w25 What do you mean "rear facing"? (do you mean a gable end?) To each is own.... they do a pretty good job hiding the ridge vent (with shingles in some cases). I guess some would think off ridge / static vents are ugly as well. However, depends on where you live. Here in Florida, we want the LEAST wind resistance (to prevent hurricane damage and water intrusion) and good static air flow. The ridge on a hip roof wins in those areas. On the old fashion "gable" roofs (still common in old FL homes) box vents and even powered gable fans can be a good thing when done right. However, hip roof with soffit / ridge should never have a powered fan yet many unsuspecting home owners here buy them everyday.
But I replace a roof, and make sure the ventilation system is on the backside of the house so that you don’t see it from the street
That’s what I mean by rear facing
I don’t see the point of this… Why pick a dark gray shingle that’s nearly black? Either compare to the lightest color shingle out there or paint one side with white oil based primer and see how much cooler that is. It makes a big difference externally as well as inside the attic.
When would you ever paint a shingle? I don’t see the point of that
LOL. The backside of the shingles is what should be measured. You only measured heat reflectivity. Also, that temperature gun you're using has to be calibrated for the surface you are measuring.
I see The comments keep getting dumber the further I scroll.
@@h2w25 Please explain.
I was expecting a much bigger temperature difference
YEAH! Pretty crazy how the results turned out!
Good video Brent I was thinking more like 15+ difference. We get this question a lot also, and we suggest that it’s generally not worth sacrificing picking the color based on temperature because after we get the ventilation working correctly . Its going to be so much cooler in the house than before. Afterwards homeowners are amazed how much less their a/c is running then before the new roof. 💰💵💸 in their pocket
@@shawnyork2083 thank you for watching and commenting. It’s always great to hear from you bro! I expected there to be a huge difference. You are right about ventilation. The darkest shingle on a well ventilated roof will hold up better than ANY unventilated roof shingle
Isle of that adds up own a hole roof.
I went from dual grey to dual black on my roof don’t notice any difference. Tires and power lines are black.
Yes!
Thanks. According much of the great depression era logic I see here, the F117A Nighthawk, D-21, SR-71 Blackbird & other black aircraft should've combusted on the runway in the Nevada desert before taking flight or shortly thereafter.
You mean the generation who built those birds? @@natas9
Great video! I wonder what the Shasta or Pearl colors would read?
Id love to get some white shingles and re-test. Atlas used to make a color called Oyster that would be great for this, but I think its discontinued
@@roofingtips I did an Atlas Pearl roof this year, pretty close to white. I might have to re-create this video with some sample boards.
Pearl is the one I was thinking of! So those can still be had?
Love the black what brand and colour pls
Those are Atlas- pristine black
I have a black roof and black Hardie siding. Perfect for winter near Canada. Not so great mid summer.
I’m 55… need to plant trees that grow very fast.
Yikes. Make sure you have good insulation and attic ventilation
@@roofingtips I’m a “net zero” certified builder. We insulate well.. attics are balanced ventilation systems or un-vented assemblies.
There isn’t s noticeable difference in temperature in the home. Mid winter snows seem to melt very slow so this home seems to be pretty well sealed
5 degrees is good. That is 85F to 80F.
109°F to the hotter black 114°F
What is the temperature in the attic?
No attic for this test. This tests surface temp
@@roofingtips a surface test is irrelevant. A test in the upstairs of a home or attic would be a more realistic test as well as AC usage due to a darker roof and electricity usage difference.
The attic space is in direct correlation with the surface temperature of the roof.
This is like a card game with my brothers kids, everyone just talking about stuff they have no idea about
what about white?
White shingles used to be readily available. There aren’t nearly as many white shingles out anymore. However, white shingles have always been regarded as cool colors
We don't care about the shingle temp only the attic temp.
Now do a white shingle.
Your video needs to be taken down and re-done. Please consider the following:
#1: 5 degrees may seem small and may not be a big deal to those watching You Tube. However, set your thermostat 5 degrees higher tonight before you go to sleep. I bet you will wake up in sweat and make the family unhappy. There is a big difference in 88 vs 93 degree summer temps here in Florida. That difference in the roof also translates though the sheeting to the attic and through the insulation reducing the benefits of said insulation / R factor. now your AC has to work harder to keep the living space at the same temp and it takes longer at night for the roof and all layers underneath through to living space to cool. Look up how much energy is saved for each "degree" one raises their thermostat... I run hot (hot sleeper) so keep my air at 73 and pay a larger power bill for that desired temp. If I raise my thermostat by just 4 degrees, our power draw in the summer goes down to what would equal approx. $100 off our power bill each month (running at 77 vs 73). So yea....a few degrees makes a big difference in the real world and may matter to people. (You should not spin it so it is not a big deal)
#2 There are MULTIPLE engineering studies and it is common knowledge today (within the building community) that solar fans or any attic fan in a properly ventilated attic (soffit and ridge) is a big negative for two reasons A: You interrupt and block the static air flow path between the powered vent and the section above to the top (at the ridge) along with with the surrounding area. You also cut off the vacuum / venturi effect between soffit to ridge that will leave hot air pockets in many places throughout the attic space. This will result in both hotter (sections) of the attic and potential damage to the sheeting for improper air flow, moisture build up, and other issues. B: By adding the additional pressure to the static airflow of a soffit / ridge vented attic, you will pull cool air from the living space no matter what as no house is perfectly sealed (it cannot be or your would have mold) as it needs to breath. Insulation does a good job keeping the cool air in the living space and hot air in the attic separate based on the engineering and static air flows from a soffit / ridge system. However, if you add pressure (or air getting sucked up form a powered fan) you are going to also pull cool air into the attic space resulting in the AC working harder to keep it cool.
No doubt the ignorant homeowner (and roofer who does not know what the heck they are doing) will "feel" that the attic is cooler with a powered fan (solar or otherwise) giving you a false sense it is a good thing. That is based on the area "below" the fan (often the attic access which is a small section) and is often partially due to the cool air from the living space getting sucked up. My dad was a pro builder in the 1980's and use to argue with people about this. Today (here in Florida) most every GC and professional in the biz will fully back what I am saying since it is now taught and in the books. This knowledge was not in the books in the 1980's but it is today. Every building engineer, architect, licensed AC pro, and GC's who were licensed in the last decade or so would all agree. Please stop using your Opinion based on assumptions that have no basis to sell an idea to those less informed. I like the look of black shingles, however, there are serious negatives you tried to cover up and dismiss.... I believe due to ignorance not due to intentionally trying to mislead people.
You can’t use ridge venting along with powered fans. We install both, but never on the same home.
@@roofingtips ahh good to know...he did not specify that in the video. agreed
100/1 you're a baby boomer.
100/1 you're not@@natas9
So, black shingles and dark gray shingles are both terrible and you should never use these on your house. Got it. Also, that bit about being taught from a young age about high albedo surfaces is called science class.
Yeah sl
That's not black. That's gray and dark gray 😂😂
Haha, that’s pretty much what black shingles look like. I don’t think there’s a true “black” anymore.
Asphalt is just a DUMB idea. I would never put that antiquated heat blanket on my home😂😂😂
What would you use?
@@roofingtips metal ALL day. I have a white metal roof with 1/2 isolated insulation and the backside deck temp is 80° on a 100°F day
Racist😂😂😂
We all know the lighter color is the way too go!!!
😎
Yeah, for trailer parks and modular homes
