I’m having my roof redone and on the roof where my roofer is going to install standing seam metal roof he put down Winterguard HT fastened with staples (because it was cold so it didn’t stick well).
The installation instructions say:
WinterGuard will not adhere to wet or cold surfaces. For cold weather tack down, use only roofing nails. Under no circumstances should staples be used with WinterGuard products.
I talked to my roofer and he said, “it’s fine, everybody uses staples.”
Should I make him redo it or is it actually fine?
