Oh they do. It’s just the hot areas in developed countries that pretend they shouldn’t be using white paint.
Comment on Awnings: a simple cooling tech we apparently forgot about

I’m Suprised people don’t just paint everything white in really hot countries. I’ve always felt that would probably help a lot.
True it would probably look bad a lot quicker.

always been confused why roofing in the NA area is often black, or close to black, it simply doesn’t help anybody.

It’s cause they are built from petroleum

like most things in life, even the clothes on your back on made from petroleum.

I don’t know for sure but I assume of it is because light roofs require more maintenance to look as nice. Nothing shows up on a dark brown or black roof. A white or light grey would show dirt and debris. I don’t want to waste my time washing my roof because my HOA doesn’t like the way it looks.
KillingTimeItself@lemmy.dbzer0.com 5 months ago
i guess so? But a dark grey roof is already literally made from asphalt. It can’t look much worse that proto road material.
Even then you could easily do a brighter grey color. Doesn’t have to be white, but nearly every roof i ever see is either black, some variant of a dark color. Not a lighter grey or red, those are lot less common.

Also, the color doesn’t make that much of a difference. Like a percentage you can count on one hand. Much more significant gains can be had from ridge vents and other ways of getting the heat out of the attic, and insulation to keep that heat from going into the house.
At least according to my acquaintance in the roofing industry, and obvs this is regarding typical US/Canada SFHs

i could see the utility in it providing natural drafting for ventilation, but honestly, with the advent of modern homes moving towards insulated attics and loft spaces, that’s definitely the correct choice.

That combined with building materials, where I live we build out of Adobe and my house stays warm in winter and cool in summer, the outside looks like mud smeared on the walls.

I am going to upvotes this … But I won’t be happy about it…

If I could find it and it was as durable as regular paint, I would paint everything that white that converts visible lights into infrared that isn’t blocked by the atmosphere. Yeet that heat right the fuck back into space damnit!
Pirky@lemmy.world 5 months ago
That reminds me of the barium sulfate paint that was discovered a couple years ago. It’s so incredibly good at reflecting/moving heat that it could even cool whatever it’s painted on. I’ll have to find a source on this again…

NightHawkInLight has a bunch of videos on making it

That video was exactly what I was referring to. Lol.
