Not sure about the quality of the roof yet, as it was just installed yesterday, but these bozos left over 20 roofing nails in my driveway. luckily, I parked in the street last night because their dumpster was in the drive still. And luckily, I also pursued the driveway for nails today prior to pulling in because I know many roofers can sometimes be inconsiderate, so I MAY have escaped any potential damage to my tires. Fingers crossed. If you use these guys, make certain they do a «clean sweep» with a magnet sweeper upon completion.
