I am waiting for my roofer to confirm a date but he is backed up.
My questions is - when is it too late to install shingles in Massachusetts? I know it is all weather related and from GAF’s website it looks like 40F-90F is the optimum install range, but at what point might you be concerned about shingles laying down/sticking, and push off the job to next spring/Summer? In October?
No major rush on my end - GAF architectural, HD shingles if that matters.
