eli5 why roofs aren’t made out of metal or something more durable than shingles?

963 views

Shingles need to be replaced every 10-30 year depending on wear and their type. It just seems so uneconomical and such a pain.

I get that metal conducts heat more easily, but couldn’t you just let a thin layer of moss grow on your metal roof and call it a day? Even if they dry out in the summer, I doubt metal + thin layer of dirt would conduct heat more than black shingles

Many roofs are made of metal, it’s much cheaper and more effective in places with heavy rain and snow. The average metal roof can last for 50 or more years and when properly installed on an insulated building they do not add any measurable increases in temperature inside the home. Shingles became popular due to the asphalt they are made from being an abundant waste product from various industries, many of which are no longer operating. Steel roofing with special paint can also be used in areas with high temperatures as the coatings can reflect much of that incoming sunlight and heat, they are also much cheaper and easier to install than shingles roofs. I’ve installed both and would never use shingles on my home, I have a steel roof because where I live we get 13ft of snow almost every winter and a shingles roof would hold all that weight and collapse my house, where as the smooth steel roof the snow slides right off.
