In Texas? Most of those shingles should be down after a couple of 80 degree days. Even if it's not "that" hot, the sun will help warm them up (surface temps) a lot.
Don't know what your pitch is, but on a lower slope roof the shingles will stand out more noticeably.
I wouldn't stress it. Even if it takes a couple of weeks. If your customers didn't give you any complaints, then you shouldn't worry either.
Hey, if you have any problems, at least you know where The Contractor lives!
:lol:
We've put on my roofs but I had my own home roofed by my best crew 1 week ago with a 30 year laminted shingle but noticed that the roof has not layed flat yet. I never noticed this as much doing other peoples roofs because I don't usually go back and check and have not had any complaints. My question is how long does it take for the shingles to lay flat and seal with the cooler temperatures that we are having here in the south.
