Asphalt Shingle Roofing in Baldwin, Maine

Census estimates put Baldwin at about 634 housing units, with a median year built of 1979. About 15 percent predate 1940 and roughly a quarter predate 1960, the farmhouses and village homes of an old mill-and-orchard town. Another 26 percent went up between 1960 and 1979, and about 28 percent have been built since 2000. Around 80 percent are single-family detached houses, and about 89 percent of occupied homes are lived in by their owners. The town's draft 2025 comprehensive plan counts about 15 percent of homes as mobile or other types, the highest share among its neighbors, and notes that population grew 29 percent in the 1970s alone. Seasonal homes are a small slice, roughly 96 units, far fewer than in lake towns such as Sebago. The oldest survivors include Valley Lodge on Saddleback Road, built in 1792 by one of the first settlers.

Baldwin is inland and upland, so salt is not the problem here; snow, cold and a long freeze-thaw season are. The nearest long-term record, from the National Weather Service office in Gray, averages about 84 inches of snow a year for 1991-2020. The south and east of town are fairly flat, topping out near 600 feet, but the north climbs into the Saddleback Hills, where Bald Mountain reaches about 1,200 feet, Winn Mountain about 1,255 and Douglas Mountain about 1,380 on the Sebago line. Homes on those slopes and ridge roads are more exposed to wind and hold their snow longer into spring. Along the Saco, Breakneck Brook and the town's roughly 2,490 acres of wetlands, low ground and wooded lots keep north walls, roofs and decks damp.

Building permits come from the Baldwin Code Enforcement Office at the town office, 534 Pequawket Trail in West Baldwin. The town's application lists deck or porch as its own use type and asks which district the lot is in, from Village Center, Rural and Highland to Shoreland, Resource Protection and Floodplain, with setbacks measured to water, wetland and resource protection lines. Work must begin within 18 months; the permit expires after two years. Shoreland zoning adds a Stream Protection district 75 feet from streams and 250-foot Resource Protection buffers around qualifying wetlands. Within 500 feet of the Saco River, the Saco River Corridor Commission requires its own permit.

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
