This contractor put new roof shingles (including water/ice shield, underlayment and new drip edge) and rain gutters on my house over a two-day period. The finished work exceeded my expectations by including such items as new vents colored to match the shingles. All the materials used were high quality and the workmanship appears to be excellent. The roof appears leak-free and intact after two storms with heavy rains and winds. I had not used Mt. Desert Roofing and Construction before and their estimate was the lowest of the estimates I received. Therefore, I was a bit apprehensive about the quality of their work but I doubt that another contractor could have done a better job. There were delays in getting the job started but once started the work went well.
