First time using a roofing company so it was very daunting. I must have shopped around for about five different companies. In the end Greater Boston Roofing had the most competitive price, best warranty (GAF certified) and they replaced our old roof (4500 sq ft) in two solid days (under more than 90 degree heat and cleaned up afterwards). That’s just incredible! Fingers crossed for the next fifty years… I don’t have to worry about my roof anymore in my lifetime.
