Metal Roofing in Casco, Maine

Census estimates count about 2,970 housing units in Casco, with a median year built of 1988, noticeably newer than Raymond's 1976. Only about 5 percent predate 1940 and around 18 percent predate 1960, while roughly 31 percent have gone up since 2000. About 76 percent are single-family detached homes, a lower share than in neighboring Raymond, and about 90 percent of occupied homes are owned by the people living in them. Seasonal use is large: roughly 1,210 units, about four in ten, are held for seasonal or recreational occupancy, from shoreline cottages to second homes. The town also runs a short-term rental registration ordinance, since many lake houses are rented by the week. The older layer is small but real, including a Federal-style house from about 1795 in South Casco.

Casco is inland, so the weather that wears on houses here is snow, cold and the wind off big water, not salt. Published normals from the National Weather Service office in nearby Gray show about 84 inches of snow a year for 1991-2020, well above the roughly 69 inches at the Portland Jetport. Deep cold and midwinter thaws alternate from December into March. Cottages on the north shore of Sebago Lake face miles of open water to the south, and Sebago rarely freezes over completely, so that exposure lasts through the winter. Houses on Pleasant Lake, Thomas Pond and the smaller ponds sit among tall pines, where shade and needle litter keep roofs and decks damp.

Casco's Code Enforcement Department, which the town calls its building department, works from the town office at 635 Meadow Road and meets by appointment. Since April 7, 2025 the town enforces the 2021 I-codes under Maine's uniform building code. The building permit application asks whether a lot is in shoreland, water body, wetland or resource protection zoning, wants a plot plan with roadside and lakeside setbacks, and records lot coverage. Permits are valid for one year. Work in the shoreland zone, within 250 feet of a great pond, uses a separate Shoreland Project Permit Application with photos before and after construction.

Metal roofs shed snow, shrug off wind, and outlast most other roofing. Standing seam panels run from eave to ridge with raised, concealed-fastener seams; metal shingle systems give a more traditional look. The site lists metal roofing systems among its roofing options. Because snow slides off metal in sheets, planning where it lands, over doors, walks, decks and lower roofs, is part of the design.

• Tear-off to the deck and repair, or preparation of the existing deck as the system requires.
• High-temperature underlayment and ice and water protection where needed.
• Panels or metal shingles installed with clips or fasteners that allow thermal movement.
• Trim, ridge, eave and valley flashings formed and installed.
• Snow guards placed where sliding snow would land on entries, decks or lower roofs.

• You want the last roof you put on the house
• Heavy snow loads and ice dams on a low-pitch or shaded roof
• A camp, barn or outbuilding where low upkeep matters most
• Repeated shingle blow-offs in wind

• Standing seam versus metal shingle, and gauge and finish
• Roof area, pitch and number of penetrations
• Tear-off and deck preparation
• Snow guard layout
• Trim, valley and flashing detail
