[GWN7]

I have to shingle my garage, the back shed and my other house in the country.

I'm going with metal for all three.

The garage was re-shingled 17 years ago with 3 tab shingles. I increased the insulation and the heat cooked the shingles.

The other house was re-shingled with 3 tab shingles 15 years ago and the sun cooked the shingles (they were 25 yr ones).

The back shed is rolled roofing that is past it's end of life.

I believe global warming had something to due to my failure of the two roofs. Each had 3 tab from two different manufacture's so I'm not sure how the 30 or 35 years shingles will hold up any better.

With the steel roof I won't have to worry about it for longer than I will be alive. Each manufacture has different ways of installing it so read/watch their videos.
