This guy Bill is a hand nailer!!! It’s a rare thing to find a roofer who doesn’t just want to get on your roof with an air gun and slap your new roof on real quick. If you don’t know the problems that air guns bring - do some homework... but no contractor will tell you anything since time is money to them and air gun gets the job done quick. This hand nailer charged the same as the other guy with the air gun but he took 4days to do the job vs the air gun company that say they would have it done in a day or two. Unless you are going to do it yourself with an air gun don’t let a contractor with an air gun go up there and slap roof on real quick. Get a hand nailer!!! Get Bill :)
