First they showed up 12 days late while the supplies layed on my driveway that long. Took 3 days to finish(only have a 1000 square ft house). Damage to an eavestrough and did not put back 2 roof vents so had to demand them back to fix problems. Sloppy appearance of shingles(not neat like normally should). Left a couple pound of old roofing nails spread in my lawn so had to run a magnet myself to clean them all up.
