Roof Replacement in Biddeford, Maine

Biddeford's median home dates to about 1952, with roughly 41 percent of the housing stock built before 1940 and 56 percent before 1960, among the oldest profiles of any town in this service area. That reflects the mill era: dense triple-deckers, duplexes and worker cottages fill the neighborhoods around the old Pepperell and Lincoln Mills downtown, many with original wood clapboard, early asbestos-cement shingle, or an aging vinyl overlay from a past renovation. Outside the mill district, West Biddeford and the areas toward Route 1 hold newer capes, ranches and colonials built through the second half of the 20th century, and Biddeford Pool adds a smaller cluster of coastal cottages and shingle-style summer homes.

The Saco River runs through downtown Biddeford before reaching the Atlantic, and Biddeford Pool, at the city's southeastern tip, takes ocean weather directly: nor'easters, wind-driven rain and salt air that accelerates corrosion of fasteners and flashing faster than it does a few miles inland. Winters bring the usual freeze-thaw cycling that works on old clapboard, paint and roof shingles all over the city, and older, poorly insulated mill-era attics are especially prone to ice damming at the eaves during a hard winter. Away from the water, exposure is more typical for coastal York County, but the age of the housing stock means storm damage often reveals problems that have been building for decades.

Building permits in Biddeford go through the Code Enforcement Office, which enters near the City Theater on Main Street, for siding, roofing, window and deck work alike. Maine's Mandatory Shoreland Zoning Act applies within 250 feet of the Saco River and Biddeford's Atlantic coastline, including Biddeford Pool and Fortunes Rocks, which restricts how close new construction and some rebuilding can sit to the water. Exterior work on buildings within the Biddeford-Saco Mills Historic District downtown can face added design review, though most residential streets in the city fall outside that district's boundary.

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
