Metal Roofing in Chebeague Island, Maine

Standing seam metal suits a place where a roof has to survive years of wind and salt with nobody around to check on it. Concealed fasteners mean nothing to back out, panels shed snow instead of holding it, and a well-installed metal roof often outlasts two asphalt roofs. Metal shingles give a similar lifespan with a texture closer to traditional roofing, which can suit an older house where a smooth panel would look out of place.

Coating choice is the first question here. Near salt water, panels with a marine-grade finish and aluminum or coated steel hold up far better than bare galvanized metal, and dissimilar metals in flashing and fasteners should be avoided. The second question is where the snow lands. A metal roof releases its snow all at once, so snow guards belong above doors, walkways, decks and any heat-pump units installed along the eaves. Panels are long, so delivery to the island has to be planned with the barge, and the longest runs may need to be ordered with that 43-foot deck in mind. Sheds and outbuildings are also good candidates for metal.

Census estimates count about 554 housing units in the town, and the median year built is 1938, which makes Chebeague one of the oldest housing stocks in Cumberland County. Roughly 51 percent of units predate 1940 and about 57 percent predate 1960. Building slowed sharply after that: only around 9 percent went up between 1960 and 1979, while about 20 percent date from 2000 or later. Nearly 97 percent of units are single-family detached houses, and about 71 percent of year-round households own their home. The defining number is seasonal use: about 263 units, close to half the total, are held for seasonal or occasional occupancy. Expect wood-frame capes and farmhouses from the fishing and stone-sloop era, cottages and former boarding houses from the summer-hotel years, and a newer layer of homes built since 2000.

Great Chebeague sits in the middle of Casco Bay, about 10 miles northeast of Portland, with open water on every side and no mainland ridge to break the wind. Nor'easters push rain and spray straight into east- and north-facing walls, and salt settles on siding, flashing and fasteners well back from the shore. The nearest long-term weather record is Portland International Jetport, where 1991 to 2020 normals put average snowfall at about 69 inches a year. Winters here swing across freezing again and again, so water that gets behind trim or under shingle tabs freezes, expands and opens the gap further. The town's own site keeps a disaster-relief page for the December 2023 and January 2024 storms, a reminder of how hard winter storms hit.

Building permits come from the Town of Chebeague Island Code Enforcement office, which posts its monthly permit reports online. The town's zoning ordinance says no building may be erected, structurally altered, enlarged or moved without a permit from the Code Enforcement Officer, and a new or enlarged structure needs a site plan showing the lot, buildings and yards. The town fee schedule has a separate category for decks and sheds, and fines for building without a permit start at double the fee. Shoreland overlay districts cover the waterfront, with setbacks set by the town's Shoreland Zoning Ordinance, and a dozen small islands in the town are entirely Resource Protection.

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
