Shingle Roofs

When you get a Tile/Slate roof here-you would reasonably expect it to last 50 years for Roof tiles & possibly 80-100 years for slate & I personally know that my Torch -On modified Bitumen Roofs will last at least 25 years.
Is the heat in Summer a factor on Shingle roofs not lasting as long in US, as it seems to me they get torn off regularly.

1. How many roofers have torn off 3-tab shingles that were over 20 years old.

2. How many roofers have torn off dimensional shingles that were over 20 years old.

3. How many roofers have torn off either of the above types that were less than 15 years old.

Dozens of roofers replied saying they had done 1 & 3, one roofer replied saying they had done 2.

A lot of it depends on the weather, one good hailstorm or windstorm can be the beginning of a not-so-slow decline.

Properly installed in a four-season climate you should be able to get ten years out of a shingled roof if you take care of it and don't get unlucky.
