Asphalt Shingle Roofing in Gorham, Maine

For the thousands of Gorham houses built since the 1980s, architectural asphalt shingles are the most economical way to put on a roof that holds up to a southern Maine winter. Laminated architectural shingles are heavier and thicker than the three-tab shingles on many original subdivision roofs, and when nailed to the manufacturer's high-wind pattern they carry higher wind ratings, which matters when a nor'easter blows across open ground.

Under the shingles, the ice barrier does the real work in Gorham's snow. The 2021 International Residential Code, as adopted in Maine, calls for self-adhering ice-barrier membrane from the eave edge to at least 24 inches inside the exterior wall line, extended to at least 36 inches along the slope on roofs of 8 in 12 or steeper. Valleys, skylights and the joints around chimneys get the same membrane. Drip edge along eaves and rakes, new pipe boots and proper ridge ventilation complete the job. Shingle color is worth thinking about: darker shades absorb more sun and clear snow faster, while lighter colors keep attic temperatures lower in summer. The fixed-price proposal names the shingle line and every underlayment layer.

Gorham counts about 6,800 housing units in the 2020 to 2024 Census estimates, with a median year built of 1988. Roughly a third of homes, about 33 percent, were built in 2000 or later, and about 29 percent date from the 1980s and 1990s, so most of the town's houses are under 45 years old. The older layer is substantial: about 14 percent of homes predate 1940 and about 21 percent predate 1960, including the wooden 19th-century houses of the Gorham Village historic district. Another 17 percent or so went up between 1960 and 1979. About 80 percent of homes are single-family detached and about 82 percent of occupied homes are owner-occupied. The estimates show essentially no seasonal housing, so nearly every house here is lived in year-round.

Gorham is an inland town, about 200 feet above sea level, drained by the Presumpscot, Stroudwater and Little rivers, and out of reach of the salt spray that wears on coastal houses. What it does get is a full southern Maine winter. The Portland International Jetport, the nearest long-term weather station, averages close to 69 inches of snow a year, with seasons ranging from far lighter to far heavier. Nor'easters bring high winds and storms that often exceed a foot of snow, and roofs carry that load for weeks at a time. Spring and fall bring repeated freezing and thawing, which drives water into siding joints, window sills and roof edges, and heaves deck footings that were set too shallow.

Permits in Gorham are handled by the Code Division of the town's Community Development department, and applications are now filed online through the SmartGov system. The town lists a Building Permit for Minor Projects that covers decks, sheds and pools, so a new deck or a deck replacement is permitted before construction; ask the Code Division whether a roofing, siding or window job needs one. Lots along the Presumpscot and other rivers fall under shoreland zoning and need a Shoreland Zoning Permit for work in that zone. Gorham also has a Historic Preservation Commission, which issues Historic Preservation Certificates for designated historic properties and districts.

Architectural (dimensional) asphalt shingles are the most common roof in Maine for good reason: they are affordable, they come in many colors and textures, and a good system handles snow, ice and wind well. Several projects on this site used CertainTeed Landmark shingles. What separates a long-lived shingle roof from a short-lived one is mostly underneath: ice and water protection at the eaves, correct nailing, and balanced ventilation.

• Tear-off to the deck and sheathing repair where needed.
• Ice and water shield at eaves, valleys and around penetrations; underlayment over the rest.
• Starter strip and drip edge at the edges, then shingles nailed in the manufacturer's nail zone.
• Step flashing at walls, new pipe boots, and chimney flashing as needed.
• Hip and ridge caps over a ridge vent, balanced with intake at the soffits.

• Granules washing into the gutters and bald patches on the shingles
• Shingles that curl, cup, or lift in wind
• Leaks around chimneys, vents or skylights
• Moss or dark streaking on shaded slopes

• Roof area and pitch
• Shingle line and color
• Layers to tear off and deck repairs
• Flashing and ventilation work
• Number of valleys, dormers and penetrations
