re: 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

I read an article awhile back that said the small city decided to start planting trees in the median, around the parks, government buildings and encouraged residents to plant trees in their yards. This caused the temperature in the small city to drop by 5 degrees.
I wish I would have saved the article or link.

Baw will be doing a spider man impersonation on anything above 8/12.

They used to sell them back in 1975 ish. Used them on a house I helped repair the roof. Looked like puke 2 years later.

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.

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

---

Metal roofs should be standard within 100 miles of the coast and in any tornado prone areas.

They are better in every measurable way than asphalt shingles and I suspect insurers will start to push people that way.

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.

I live in a neighborhood with these on every house. You just have to chemical pressure wash every 3-4 years, cost around $300 (bout tree fiddy for the OT). But apparently homeowners carriers are starting to frick with the reimbursement because they are expensive to replace.

What’s the costs of a metal roof versus a typical shingle roof? 50% more?

How do you propose one should wash shingles without damaging them or shortening the life of the roof?

---

Do you even soft wash bro?

I don’t consider it that way. And I’ve never been a believer in global warming. But we just had the road in front of the house blacktopped. The heat reflected off it makes it unbearable to walk on. That made me think of the millions of miles of earth that has been concreted and blacktopped. That has got to be making a difference in earth’s temperature .
