Any roofers in here with some tips? I got a quote from my future bro in law for $3000. He was quoting materials and $1000 for labor. I was at Home Depot last night and while I was there, I figured, "Hmm, lemme see how much materials would actually cost". All said and calculated, my entire back roof will actually cost around $170 in materials. Including weather watch, building paper, new flashing, tar, and cobra ridge vent. So weather permitting, I'm going to attempt to do my roof this weekend. I'm thinking I'm going to do a skylight while I'm at it, since I'll be saving $2700... Any tips from a pro in here to keep me from doing it again in 5 years?
