If I had only known how quick & easy these guys were going to make replacing my roof shingles, I would have hired them sooner!! They worked like a “well oiled machine” and completed both my house and garage roofs in less than one day!! I returned home to a beautiful new roof and zero mess…like they were never even there.

Straight Line Roofing and Siding did an excellent job putting a new roof on our 100+ year old New England style house! Ernie was very professional and responsive to all our questions and concerns! They stripped the old roof off and installed the new one in ONE day and left no debris behind! I highly recommend them!
