Attention Roofing Contractors, or people who know or work with one:?

Question

I know rain is somewhat a mixed blessing: rain is BAD in that it delays a contractor from working, yet it is GOOD because it wears on the roof making an otherwise good roof in need of repairs/replacement sooner (lengthens, yet increases, backlog).

In terms of heat (not so much extreme heat, but just hot weather): Is it good, bad, or mixed (as it is with rain).

Thanks in advance - I'm trying to better understand the moving parts of the industry... Please explain, and source for the "Best Answer"

Answer 1

Rain washes the protective granules off of the surface of the shingles exposing the asphalt impregnated mat to the sun and weather. The sun causes the unprotected shingle to dry out and crack, which leads to leaks.

Hot weather not usually a bad thing as long as you don't walk on the shingles and damage them when they have turned soft in the heat.

Good luck with your roofing education.

Answer 2

my boyfriend is sitting here so i asked him. he's done roofing for over twenty years...he said in his expierence when it is hot outside repairs can be held up due to shingles curling under foot.
