Other than hiring myself, a couple of my friends and family, I don’t know.
Here’s the second roof in a year I’ve looked at because shingles are falling off. The shingles were not very old on either roof, they were just installed incorrectly. I feel bad that some homeowners have paid / are paying for very poor quality work.
My older brother asked me the other day, when he buys a house – how does he hire a contractor to work on it ? Word of mouth was the best thing I could think of. Get recommendations from other homeowners, and ALSO ask lumber yards who they hear good things about. This probably won’t work at a Menards or Home Depot, etc…the big chains, but if you are in an area with a small lumber yard – they know who pays their bills, and who has a good reputation to them anyway. Most of all, Ask if how the contractor is about honoring their warranty? Does their warranty cover 30 yr Shingles that fall off the house within a couple years ?
I hope everyone is able to find the contractor they like and can work with, who does quality work!
