I've had a couple of roofers out to my place. Both are long-time well-respected firms. One a father and son family business, the second a well-respected partnership. I know each will do a good job.
Roofer A says that nowadays, in our mountain region, very wet, fairly windy, infrequent snow, that he has pretty much gone to architectural shingles and that is all he recommends nowadays.
He also pushes that fact that his roofs are all hand-nailed by about as stable as a crew as you can have in the roofing business, which he admits isn't necessarily saying much.
Roofer B wants to do three-tab and is warning that since I have a tongue-groove roof deck, that he may HAVE to do a plywood overlay, but can't tell until he gets the roof stripped.
Roofer A wants $4700 for the 30-year architectural, touting the superior shingle and the hand-nailing. Roofer B sez $2800 for three-tab, power nail guns, and a possible $1200 surcharge for a "maybe" plywood overlay.
Anything obvious here. Is hand-nailing that superior?
