This 40-yr. warranty is more than twice other roofing companies provide in Boston Ma. G.F. Sprague is able to provide a 40-yr warranty due to our extensive training, certifications, and experience. We are one of a few contractors who carries a DCAM License (#08-0165). The Division of Capital Asset Management (DCAM) is the state agency responsible for major public construction and real estate services for the Commonwealth of Massachusetts. The agency promotes quality and integrity in the Commonwealth's building construction and real estate operations. A DCAM certificate is the only one that qualifies a contractor for a specific trade, and a contractor must be recertified by DCAM every year ($ 10,000+). This makes it a good measure of the quality of a contractor. We also provide 24/7 emergency response for all roofing and storm damage repair work for the town of Boston Ma. You can reach us any time at 1-781-349-5673. As part of our inspection and assessment process, our technicians bring a ladder, a clipboard, and a camcorder with them to your home in Boston.
