Now heres a frightening thought.
I'd never even thought of that. The roofers out here are crap. Two reroofs ago they tiled over a skylight. The last reroof, they sprayed on styrofoam. I wouldn't even be surprised if they blocked up my gas water heater vent. It's in the center of the house.
I you want a shabby roof job, get one in Vegas BTW.
I've had 5 roofs in 20 years. Not a very good average. And those guy, well, they do terrible work with little recourse to get back at them. They own nothing. They hire bums. Their bond is a joke. The Nevada State Commission fines them $120 for $200,000 of bad roofs with code violations. They pay and stay, or don't pay and open shop in Arizona for 5 years, then come back. It's a terribly bad deal for homeowners here.
