Asphalt Shingle Roofing in Yarmouth, Maine

The Census Bureau's 2020-2024 American Community Survey estimates about 3,600 homes in Yarmouth, with a median year built of 1973. Roughly 17 percent predate 1940 and about 27 percent predate 1960, while the biggest share, about 39 percent, went up between 1960 and 1979; only about 11 percent date from 2000 or later. About 80 percent of occupied homes are owner-occupied and about 76 percent are single-family detached, with roughly 120 units held for seasonal use. The town's 2024 comprehensive plan describes the village core as mostly mid-19th-century wood-frame single-family homes, Greek Revival first and Italianate second. After the 1955 causeway to Cousins and Littlejohn islands and the 1961 arrival of I-295, conventional subdivisions spread along North Road, East Elm Street, Bayview Street, Princes Point Road and Granite Street, with condominium clusters following in the 1980s.

Yarmouth's building code writes its design conditions straight into the ordinance: a ground snow load of 60 pounds per square foot, a design wind speed of 115 mph, weathering rated severe, a 48-inch frost line, a winter design temperature of minus 5 degrees and ice shield underlayment required. The town fronts Casco Bay along White's Cove and Broad Cove, so houses on Cousins Island, Littlejohn Island, Princes Point and the points along the shore take salt spray and open-water wind during nor'easters. Portland, the nearest long-term weather record, averages about 69 inches of snow a year. The comprehensive plan flags sea level rise along the shoreline, including stretches of the Talbot Road connector on the islands, and the town publishes flood and coastal bluff maps.

Building permits go through the Yarmouth Code Enforcement Office at Town Hall, 200 Main Street. Chapter 301 requires a permit before any building or structure is erected, remodeled, demolished or relocated, and work started without one pays double the fee. The town notes that applications take about 30 days on average to review, and building permits must be mailed or dropped off rather than emailed. Inside the Upper Village, Lower Village and Royal River Manufacturing historic districts, all exterior changes go to the Historic Preservation Committee, whose review is mandatory but advisory. Shoreland permits apply near Casco Bay and the Royal River.

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
