Ok, I’m new…and not a roofer.
I’m either having a blonde moment here or am missing something obvious but I’m confused…ie I read somewhere that the cellaphane strips on the backs of shingles are just there to stop em sticking together in the package, and you dont have to remove em before laying the shingles ? How then will the shingle below adhere to the one above if the strip is left on :?:
Apologies if this is one of those much asked questions, I tried a forum search but it didnt help.
