Roof Replacement in Brunswick, Maine

Snow, ice dams and wind drive most roof replacements in Brunswick. Winter snow near the coast often gets heavy and wet, and heat escaping from poorly insulated attics in older houses melts it from below, so water refreezes at the eaves and backs up under the shingles. Steep gable roofs on the Federal and Greek Revival houses shed snow well but are hard to work on, while the low-pitched ranches and split-levels from the 1960s and 1970s hold snow longer and show leaks sooner.

A full tear-off lets the roof deck be inspected and replaced where it has softened, and it is the time to fix ventilation, which is the underlying cause of many ice dams. Houses on Mere Point and the bay shore also need attention to edge metal and fastening against wind. Downtown, some older commercial and mixed-use buildings have low-slope sections that need membrane rather than shingles. Ask the Planning and Codes Office what paperwork a re-roof needs before the dumpster arrives. Cardinal's owners measure the roof in person and give a written fixed-price proposal for the chosen material.

Census estimates put Brunswick at roughly 9,500 housing units with a median year built of about 1982, so the typical house here is younger than in Portland but the range is wide. Close to one in five units dates from before 1940 and about 31 percent from before 1960, including the houses of the downtown and the Bowdoin neighborhoods. Another 16 percent or so went up between 1960 and 1979, and roughly 27 percent is from 2000 or later. About 71 percent of occupied homes are owner-occupied, and only about half of all units are single-family detached houses, which reflects the apartments, student housing and multi-unit buildings near the college and Maine Street. Seasonal homes are a small share, about 165 units. Expect clapboard Federal, Greek Revival and Colonial Revival houses in the historic districts, and vinyl-clad capes, ranches and colonials farther out.

Brunswick is coastal on its south side and inland on its north. Mere Point, Maquoit Bay and Middle Bay put houses in the path of salt air and wind off Casco Bay, while neighborhoods near the Androscoggin and out toward Durham feel more like an inland town. The Portland Jetport, the nearest long-record National Weather Service station, averaged about 69 inches of snow a year over the 1991 to 2020 normals, and Brunswick's own climate table shows roughly 51 inches of total precipitation. Winters swing above and below freezing many times, which works water into clapboard joints, cracked caulk and shingle edges. Nor'easters drive rain sideways into the east and north walls, and the shore points take the hardest wind.

Building permits in Brunswick go through the Planning and Codes Office at Town Hall, 85 Union Street, on paper or through the online permit portal. Maine's building code moved to the 2021 International Residential Code on April 7, 2025. Much of the historic core lies in the Village Review Overlay District, where the Village Review Board issues a Certificate of Appropriateness for alterations; the town notes that replacing windows, facades and ornamentation with identical styles and materials is not subject to review, and staff can approve minor work not visible from a public way. Waterfront lots within 250 feet of tidal areas also fall under shoreland zoning.

A roof replacement strips the old roofing down to the deck, repairs what is underneath, and rebuilds the whole system: underlayment, ice and water protection at the eaves and valleys, flashing at chimneys and walls, ventilation, and the new roofing itself. Maine roofs carry snow for months and see ice dams at the eaves, so the parts you never see do most of the work. The site covers architectural asphalt shingles, metal, cedar shake and flat or low-slope roofing.

• Old roofing is torn off to the deck and hauled away, with the yard and plantings protected.
• Soft or delaminated sheathing is replaced before anything new goes down.
• Ice and water shield goes at the eaves, valleys and penetrations; synthetic underlayment covers the rest.
• Drip edge, step and counter flashing, and pipe boots are installed new.
• Ridge and soffit venting are balanced, then the new roofing is installed and the site cleaned with magnets.

• Curling, cracked, or missing shingles and granules in the gutters
• Ice dams along the eaves or water stains on ceilings after thaws
• Daylight or damp sheathing visible in the attic
• Sagging roof lines or spongy spots underfoot
• A roof at or past the age its material was made for

• Roof area, pitch and complexity: valleys, dormers, skylights, chimneys
• Number of existing layers to remove
• Sheathing repair found after tear-off
• Material: asphalt, metal, cedar or low-slope membrane
• Ventilation and flashing upgrades
