Why aren't white shingle or light colored roofs more common in the South and hot climates?

They are doing this in one of the big cities in Italy. Common sense. Drops the temperature around the city around 5 degrees. Will also in turn save money from not needing quite as much electric.

Not shingle, but the house I lived in while in the usvi had a white roof. Made sense to me.

Louisiana refuses to stop builders from putting six houses on an acre of land. No way will they require common sense lighter color roofs.

Because they will just turn black with mold/mildew within a year anyway.

houses/buildings in Flarda use lightweight concrete tiles in lighter colors. They do well and look nice, but look like shite after 5 yrs of dust, smog, mildew build up.

The home I grew up in the early 70’s had been built by a doctor in our town. It had a white roof that was some kind of a hard grout or something. It came in 5 gallon buckets and you spread it over the roof and it would dry hard. It was pure white. It seemed pretty durable because I would get on the roof pretty regularly to get stuff off of it or just for the shite of it. We did have to wash it yearly with bleach if I remember correctly.

It was chalky and you could break it though.

Galvanized sheet metal roofs in light colors should be more popular.

White sealant is pretty standard in the Caribbean. I’ve done some work on them with bi-facial solar and it’s pretty sweet.

It would need to be pressure washed every few years because of the humidity.

Just got a metal roof on our house and picked a lighter color


It’s made a difference. It’s not real light but not black either. Kind of tannish

White or silver metal roofs are very popular in coastal AL. Look sharp as well

Pre-Ida, my house has a white metal roof.
It now has a medium/light blue colored metal roof.

I did not notice a huge difference inside.

One of my former coworkers has a house trailer that he used as a camp in Dulac. He painted his whole shingle roof with white cool-seal. He said it dropped the electric bill.

Can you imagine how stained white shingles or roofs would get here in south Louisiana with all the dirt, dust, and pollen?

Getting Algae Off My Roof

Found the linked article while searching for the use of zinc to keep algae off of a roof. The zinc or copper needs to remain unfinished, not painted or coated.

Not mentioned in the article is to verify that the metal used is compatible with other metals or there will be galvanic corrosion. There are compatibility charts that can be found online.
