It is technically not a (local) supplier, rather the manufacturer.

I have a friend whose shingles were replaced. She said the manufacturer called her while she was on vacation. The call was from the national headquarters of the manufacturer which I think is in Pennsylvania. They said that her shingles were a bad batch and they reroofed her house, this was last year.

The name of the manufacturer is Owens Corning if I remember correctly.

They owned up to it and fixed it.
