How White Roofs May Help Reduce Your Air Conditioning Bill

- As the world bakes in brutal historic heat, painting your roof white may be a way of cooling off Earth. Jon Parker of American Home Contractors in New Jersey says painting a roof white can cut air conditioning bills by reflecting the sun's rays. To try to tackle climate change, a team of scientists at Purdue University developed an ultra-white paint that is officially recognized as the whitest paint ever made. Scientists say it can reflect 98% of the sun's rays.
70 degree difference is impressive
Never paint or coat your roof

Why?
@@U.Odyssey it's not going to last long because you're going to damage the roofing material
Surface temp! You live 8-12 feet below that. And heat doesn't go down
@@justayoutuber1906Heat radiates though. If you have an attic that isn't ventilated the heat from the attic will cause your home to be hotter. Same thing with the heat from the roof.
That actually makes perfect sense. Everyone always says that metal will get the hottest in the sun, but it really all depends on the color as well. When I was at the park with my kids I noticed the blue metal was only warm in the direct sunlight when the black plastic was so hot it almost burned me. They should start using this idea to help the parks as well. A child is less likely to burn themselves if it was painted too. I know if I can get burned on it then it'll burn a child so they should keep that in mind.
It depends on the metal, too. Steel will get hot faster than titanium because titanium is a poor heat conductor, compared to other metals.
black roofs matter too inside edition is racist
@@kancelas bro ain't no park using titanium 💀
Well you're getting burned anyway
@@EikottXD that was just an example.
Fun fact: Wearing a white shirt also helps reflect white light so that you won't feel hot all the time.
Especially cotton. Not polyester. You'll sweat like a mofo
Yep
If you're a white person wearing white. Nobody can see you.
You can have more UV penetration though depending on the material
This is recently proven to be false, color does not matter
This is literally 9th grade science. It’s called albedo and white has a lot of it. It reflects the light. It also explains why when there is snow on the ground the ground seems so much brighter when the sun is hitting it. So yes the color white reflects sunbeams as well as heat
black roofs matter too inside edition is racist
What does sex drive have to with the color white?
@michaelg6455 that's burrito.....
I learned this is 2nd grade bud
@@6z0 And not proper spelling it seems
As someone who works in attics during the summer, this would be a dream come true
Lol it would still be hot inside. A white roof doesn’t block outside temperature, just reflects light.
I’m
Very surprised why people did not know this.. my roof been painted white for more than a decade.. I painted myself only because I knew it reduce the heat.
Ppl care about the look of there house but I’m sure most ppl don’t know
black roofs matter too inside edition is racist
You were ahead of your time.
@@mrbojangles9841 🤷♂️ I just think that people don’t want to spend time and money to do it.. which I understand.. it’s not something you can just do and finish in an hour..not everyone understand that there’s a bit of process to it, like it needs to be coated, primed, then paint and need to be right paint.. so yes this is why I think most people don’t do it.. as far as color..everyone knows that white color reflect heat.. but painting your whole roof with white isn’t just splatter any white paint on.. and that’s why people don’t bother.. however I do think the housing industry should start requiring all roof be white as standard.
Same. Cool seal
I live in Arizona and had a new roof (white) put in right b4 summer. I havent noticed a big difference, but it was 110 here last week and the hottest it got was 80 inside (with 1 swamp cooler running) Not bad for 70.00 electric bill in summer
This working. I swear. We have 1/2 year white -everywhere.
Hola from Finland 🇫🇮
Rest in peace, Steve.
Ordinary first name, Last moments of advice.
Nature took its course.
Make sure you use white roof coating which is siliconized and last about 25 years before you can coat it again
Why not sell white roofing shingles instead of having to paint them?
They do. This is just a cheaper option.
It made a difference in my house. My attic fans turn on less and my energy bill is less. I have white composite shingles.
My HOA would fine me every week 😂
Why would you buy property in an Hoa?
Why in the world did you even think of much less actually buying in a HOA????
Your worst mistake, keep suffering! Lol. I’ll be surprised if hoa changes the rules to accommodate healthier ways
@@gigiitsme7236 my HOA isn’t that strict, actually. I like an HOA, because it prevents property value deceases and keeps things clean and neat. I live in a half million dollar house. I don’t want neighbors ruining that.
@@RabbitWatchShop
I'd take a smaller house on private land....away from neighbors and where it's quiet and no restrictions
They do this in Greece, it is nothing new, not a big break through like inside edition desperately tries to make it.
Exactly, I thought is a common sense.
America lacks the sense...
Bro inside edition is not greek. It's a national news for the united states so of course it's going to be focused on what happens in the US.
What saves more money: painting your roof white to keep cooler in summer or leaving your roof black to heat your house when it's cold outside. Maybe a detachable white cover of some sort is a better option.
Excellent idea. Put white canvas on your roof in the summer and remove when weather get cooler
@@error-mc5xwGreat idea!
put the rainbow one in june!
Just wondering why that guy that died from the heat was wearing gloves, jacket and a hood. If its hot why would you wear that?
I believe some people might do it avoid getting sunburn if they have a skin condition. Though, wearing winter clothing in warm weather (especially desert heat) is highly unwise IMO.
I wear my heavy leather motorcycle jacket when riding in heat. It actually stays cooler inside for a few hours.
Why on earth would you want to be a tourist in Death Valley?? I’m from SoCal, that’s hell on Earth
“I see a red door and I want to paint it Black”
Idk but that quote “THR WHITEST PAINT EVER” hit different lol
I bet it purchases travel insurance every time it goes on vacation
(It's a Family guy reference for those not in the know)
@@ThePieMaster219 family guy has beeen irrelevent for a decade
Oh wow, a 70 degree difference is actually enermous
Just stop already.
I live in south Florida where the average for the past 3 weeks has been above 90 degrees. That doesn’t include the humidity which makes you feel even hotter, my houses AC is always set around 71-68 and I’m still sweating in my own house. This heat is unbearable, I start sweating just walking to my trash can to take out the trash
I'm in northwest Florida and it's miserable. I broke into a full sweat just running to the mailbox and back. It's way too hot!
Why don’t you just move ? 😳
@@cruzmalibu4361 cause i’m in college 😭
@@ender2617 …go to college in Alaska 😳🥶
That temp would freeze me. 🥶
77 is the lowest I can tolerate and even then I'm in bed under a blanket
Where I live all the houses have white painted roofs made to catch water with under house tanks, pump and pressure tank for supply.
As for hydration in the heat, that's why Liquid IV exists.
Roofs about to be noticeably dirty lol
It works. I heard some years ago about Los Angeles trying to paint some of their streets as an experiment to see how it would work. I doubt they bothered to keep it up though since I haven't seen any more of it.
Might be most of the money is going towards paying the homeless to be homeless
Probably because it's a stupid idea.. Reflected glare from the streets can blind/strain people's eyes causing more vehicular accidents to happen except if everybody wears polarized shades.
How many people automatically assume this is racist..?
I never understand the Death Valley tourism. So you drove all the way there just to get hot?
Yeah, let's all go to the digital thermometer at the DV Park and take our pictures there. Good idea until the car breaks down and they find themselves desperate for the next vehicle to come along.
You might meet the Undertaker
It's pretty nice in the winter.
ODK ..they know the risk and its on them to stay safe and not get heat stroke. I went to Death Valley just after Christmas in 1986 It was so cold I was layered in clothing. I would never go anywhere without checking on the weather conditions before I went.
What If you paint It Black?
The trouble is keeping them white. On roof it goes grey. I reckon cover your roof with solar panels better as they create electricity and shade on the roof. It's more expensive but in long run better.
Absolutely WILL bring down the cost in summer time.
Wow. Forecasters say that the high temperatures can continue well into August. So surprising for summer in the Northern Hemisphere.
Send that paint to Florida please! Where do i buy it?
Yes this is great it should be standard
Painting your roof white is not really that effective. If you have insulation in your attic and good roof ventilation, the surface temp of the top of your roof has very little to do with indoor livable space temp. Spend the money on a power vent or more attic insulation. Remember, you live 10-13 feet below your roof if you have an attic, and heat goes UP, not down.
In india its commonly seen ...it definitely reduces the heat and humidity inside the house for some amount
Literally has been the coolest summer in the past 5 years tbh I don’t know about this heat dome
But 48%-87% of heat gains comes from windows not the roof....this means blocking heat from windows is going to be more effective and also probably cost a lot less
Did this to my roof 8yrs ago. It does help.
what brand paint did you use and is it safe to use on shingle type roof
I remember learning this in high school lol people still won't do it.
Start passing laws. White painted roofs
They usually do that to metal
death valley ain't joking 💀💀
Does this work in a shingle room?
I’m sharing this as a reel on Facebook. Let’s all do this 🙌🏻
But is it legal to paint your roof?
@traybern the roof not the inside of the house. Here in the state you need a permit for everything
Actually i dont have to wait too long, its suppose to be 82 degrees on sunday here in californiq which is not bad.
@:43 seconds, points the infrared laser thermometer farther away from the roof….@:48 seconds, practically touches the roof with it. 😂
It doesn’t make a difference. It reads the temperature of the first surface the laser touches. He could be 20 feet away and it’ll still work the same and show the same numbers. Maybe a 1 degree difference
Need it in Phoenix and Las Vegas!
Is using a mirror better than white?
What about white shingles? Is there such a thing?
This is stuff you learn in 5th grade shocked not as much people know this
Why not reflective paint or material
It make the air around you hotter tho. Cool pavement failed in arizona for the same reasons
Heat tourist wouldn’t be out there if they worked in the heat. I work in the heat it suck’s.
Me too in tucson,az
They should try roofing or road work! Lol
Plot wist now people will paint themselves white.
next on inside edition:
how black roofs may help reduce your heat bill
I'll stay in the middle with a Grey roof! Lol
Greece has been doing this for along time. They even paint the trees white sometimes
Makes the house looks ugly!
Why was the 2 percent painted white in Africa?
I thought this title was fake until i read it over again.
Time to paint my roof white!!
Wouldn't it even out? In winter, you'd spend more for heating. I guess this is only a problem for northern states.
Another trick my dad used to do is spray the roof with water to cool down the house and it worked.
Water bill up!
Just paint it one time instead of continuing to use your water which at the end of the year would cost most than that little bucket of paint
@@gigiitsme7236 He would only do it once in the evening for like 10 minutes, it's not like he would stand there and do it day and night for hours on end. It's nothing more than watering the grass. If you can afford watering your front lawn through an automated system, you can afford to do it for a few minutes and your water bill won't take a significant hike. I understand your point that the paint method is more cost effective and efficient. However, if you live in an H.O.A. this may be out of the question, and even if you don't, who wants their roof to look all white? It's an eye sore.
It would be nice to have air conditioning budget does not allow
It works in India where they do this.
The sahara is allready white, why paint it?
Yes
100% right,
From
Pakistan
Did people just figure this out?😂
Ummm...the guy who died...why was he wearing multiple layers of clothes including a coat?? It's no wonder he died....
imagine wanting to experience the hottest place on earth before you die, and getting your wish.
When is the future that has domes over populated areas? We need domes now.
The word DUH comes to mind. NEVER NEVER NEVER use dark colors on a roof
It's nice when it's sub zero on a sunny day when your roof helps warm your house. It depends where you live. We need a black roof in winter and a white roof in summer. OR TREES like in the olden days.
I sometimes wonder why can’t I wear white after Labor Day
Cool roof.
I really want to try this
No really? Top notch reporting here
This isn’t really a new concept, look at a satellite image of Bermuda. There isn’t a dark colored roof in sight.
Well what about the heat in the winter
What would the paint do in the winter? Would it make it ❄️?
Nothing. Cold weather is dealt with by the building's insulation.
Wow the heat God work mysteriously AMEEN
Im glad i installed solar panels this year
Ok, but will your house be even colder in the winter?
Most likely not
But, Answer: Heater
I think no.
No
You can't see the paint with a foot of snow over it. Snow is white too.
@@chrishince8947Not every state or city experiences snow though, let alone several feet of it. Winter around America, even in cities _with_ snowfall, often looks like dark clouds, short days, severe freeze or rain, and varying degrees of ice. Here for example, we experience snowfall, but not the kind that packs or stacks, and winter just means "very cold" + ice or clumps of snow (that just devolves into ice).
It's also why I tend to wear white shirts, it reflects more light, therefore reflecting more heat.
Best part is the two morbidly obese park rangers in death valley posing with the sign. Thats healthy 😂😂😂
Yes, just like EVERY summer. It's hot. That's what summer does.
Every hot country in Europe: great idea, why didn’t we think of that
fire
Put foil on it even better
Meanwhile my whole room is painted Black
The whole island of Bermuda has been doing this for hundreds of years.
How'd you get up there
Reduces air conditioning bill, but increases the bills from the heating during winter.
This doesn’t help as soon as it rains it will wash away
You do realize that they paint it on times when it won't rain, paint will dry
Why is this news? Everything I buy is white. Even my car
i had been watching that Thomas and friends episode buckled track episode and they talk about the white keeps everything not hot but cool down I had been wearing white shirt when I working and surprisingly it didn’t make my arm pit sweaty
They've been doing this in Hawaii for years
That would be illegal because it causes planes to crash if light is reflected at them
Nothing will help humans will not change their ways, Good Luck Everyone . 🌏
