Cedar Siding & Shingles in Harpswell, Maine

Cedar shingles are the traditional skin of Harpswell. The Shingle style summer houses of the Auburn Colony, listed on the National Register in 1985, and generations of island cottages on Bailey and Orr's show how well a shingled wall weathers to silver gray in salt air. Cedar clapboard fits the other side of the town's history, from the 18th-century clapboard walls of the Harpswell Meetinghouse to the farmhouses along the Neck.

Cedar is not maintenance-free in this exposure, and it pays to be clear about that. Walls facing the water lose finish quickly, fog and shade feed mildew, and shingles on the weather side can cup and split without airflow behind them, so a vented rainscreen or breathable underlayment helps them dry. Fasteners must be stainless steel, since galvanized and plain steel can stain cedar in salt air. Owners who close a cottage for the winter may prefer natural weathering or a bleaching stain, which asks less of them than a painted finish. Pre-stained or factory-finished shingles and cedar-look fiber cement are options worth comparing on the most exposed walls.

Census estimates count about 4,300 housing units in Harpswell with a median year built around 1979. Roughly one in five units predates 1940, about 29 percent predates 1960, around 22 percent was built between 1960 and 1979, and about 19 percent dates from 2000 or later. More than 91 percent of units are single-family detached houses, and about 83 percent of occupied homes are owner-occupied, both far above most Cumberland County towns. The most distinctive number is seasonal use: around 1,440 units, about a third of the housing stock, are held for seasonal or recreational use. That means cottages and camps that sit closed for months, next to year-round capes, farmhouses and larger newer homes on the water, often clad in cedar shingles or clapboard.

Few towns in Cumberland County are as exposed. Harpswell's land area is about 24 square miles against more than 100 square miles of water, so much of the town sits close to the bay and the wind has a long open run to reach them. Salt spray settles on siding, glass and roof metal, fog keeps surfaces damp for days, and nor'easters push rain sideways into east- and north-facing walls. Snowfall at the Portland Jetport, the closest long-record National Weather Service station, averaged about 69 inches a year over the 1991 to 2020 normals, and wet coastal snow loads roofs and decks quickly. Repeated freeze-thaw cycles still split paint, loosen shingles and heave shallow footings.

The Harpswell Code Enforcement Office requires a building permit to alter, repair, renovate or replace any existing structure. Its permit guide specifically lists decks, even when built off-site, and window and exterior door replacement. The permit must be posted before work starts, review takes about 14 business days, and an accurate plot plan is expected. Structures must stay within the building envelope: in shoreland zones, 75 feet from the highest astronomical tide and 25 feet from boundary lines. Permits run one year, or up to five with a substantial start, and inspections include a final.

Cedar clapboards and shingles are the original New England exterior, and for shingle-style cottages, capes and historic homes nothing else looks quite right. Cedar is naturally rot-resistant and light, but it is wood: it needs airflow behind it and a finish that suits the exposure. Pre-finished shingles, such as the Maibec shingles on several projects shown on this site, arrive stained or primed on all sides, which cuts the upkeep and evens out the color.

• Walls are stripped, repaired and wrapped; where it helps drying, a ventilated or drainage layer goes behind the cedar.
• Shingles are coursed and laid out so exposure lines up at windows, doors and corners.
• Stainless or hot-dipped galvanized fasteners are used so they do not stain or corrode.
• Corners are woven or finished with boards, and trim is detailed to shed water.
• Pre-finished product is touched up at cuts; natural cedar is left to weather or finished as you choose.

• The house is a cape, shingle-style cottage or historic home where cedar belongs
• Existing shingles are cupped, split, missing or black with mildew
• A historic district or your own taste calls for real wood
• You want a natural finish that weathers to silver-gray

• Clapboard versus shingle, and grade of cedar
• Pre-finished versus natural or site-finished
• Coursing detail, corner treatment and trim
• Wall area, height and tear-off
• Any rainscreen or drainage layer behind the siding
