Roof Replacement in Windham, Maine

Census estimates count about 8,700 housing units in Windham, with a median year built of 1985. Roughly 27 percent of homes were built in 2000 or later, and about 21 percent between 1960 and 1979, while only about 12 percent predate 1940. About 85 percent of occupied homes are owner-occupied and roughly 79 percent of units are single-family detached. Around 780 units are held for seasonal use. The town's 2017 comprehensive plan notes that many once-seasonal camps around the lakes are now lived in year-round, still reached by old gravel roads built for summer use. It also records that Windham's population held near 2,000 from 1830 to 1940, so most of today's houses belong to the decades of growth that followed.

Windham sits inland, so salt spray is not the main enemy here; snow, cold and lake wind are. Homes on Sebago Lake near Jordan Bay face a long reach of open water, and the lake region is known for sudden weather changes in every season. Houses on Little Sebago, Highland Lake and the town's smaller ponds sit among trees that keep walls shaded and damp. The Portland Jetport, the nearest long-record weather station, averages about 69 inches of snow a year on 1991 to 2020 normals, with January lows near 16 degrees. Frequent thaws and refreezes through the winter push water into siding laps, roof edges and deck framing.

Windham's Code Enforcement department, at 8 School Road, administers the town's land use, building, plumbing and electrical codes, and permits are applied for through the town's online portal. Decks are structural work, so check permit needs there before building one. Properties within 250 feet of Sebago Lake, Little Sebago, Highland Lake, the Presumpscot or the Pleasant River fall under shoreland zoning, which the town administers and which limits building near the water. Windham adopted a historic preservation ordinance in 1989, but its 2017 plan says no local historic district boundaries were ever put in place.

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
