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"
