Expert Roofing & Siding Construction

Massachusetts requires a building permit for roof replacement, reviewed by the Canton Building Department. State code requires ice-and-water shield membrane at the eaves, in valleys, and around penetrations — important given Canton's ice-dam exposure. A full tear-off to the deck is generally preferred over an overlay because it lets the roofer inspect and replace damaged sheathing and lay the ice barrier correctly; code caps roofs at two layers. Properties near the reservoir or the Blue Hills edge may have wetland-buffer considerations for staging and debris, though the roof permit itself is standard and reputable contractors handle it.

Canton roofing costs sit in the typical suburban range. A standard asphalt-shingle tear-off and replacement generally runs $8,000–$24,000 depending on size, pitch, and complexity — simpler subdivision homes land lower, older mill-area homes with steeper roofs higher. Flat or low-slope EPDM sections on porches and additions run roughly $7,000–$18,000. Standing-seam metal runs about $20,000–$45,000, and slate, found on some older homes, higher still. Steep pitches, multiple stories, and heavy flashing around chimneys and dormers add labor.

Massachusetts requires a written contract and a Home Improvement Contractor registration for most residential roofing work; ask for the registration number and check it before paying a deposit.
