Coulda, woulda, shoulda. You're Monday morning quarterbacking a
business owner's decision whether to risk having to pay guys for the
day if they get rained out. Not all construction workers are
salaried.

Light rain is not a problem. I personally don't like to work on a wet
roof, even a lightly wet roof.

It's done all of the time and rarely causes a problem. The biggest
potential problem is that the roofing paper will absorb water, wrinkle
and the shingles won't lay flat. Since it just rained and they were
essentially shingling at the same time, and since you are using
heavier architectural shingles, it's not a worry.

Shingles are waterproof - both top and bottom. Water won't hurt
them. If the bundles of shingles had been left in the sun, and the
sealing strips had glued the shingles together you'd have something to
worry about. Well, not really, since the roofer is probably supplying
their own materials you are not responsible for that either.

That is a perfect temperature for shingling. Too cold and they crack,
too hot and the roofers' boots chew up the shingles.
You seem to be nervous about this roofer and nothing you have written
indicates a real cause for concern. Is there some reason the
contractor makes you nervous?
