Cedar Siding & Shingles for Harpswell homes

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.

How a Siding Wall Assembly Works

  1. Sheathing — the structural wall surface everything else attaches to
  2. Weather-resistive barrier — a wrapped membrane that stops bulk water while letting vapor escape
  3. Rainscreen gap — a drainage and drying space between the barrier and the siding
  4. Siding — the visible cladding, fastened over the furring strips
  5. Window flashing — tucked under the barrier above and lapped over the siding below, so water never gets behind it

Harpswell housing at a glance

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.

Weather and exposure in Harpswell

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.

Permits and design review in Harpswell

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.

Codes & Permits for Cedar Siding in Harpswell

In Harpswell, exterior-work permits come from the Town of Harpswell Code Enforcement Office (263 Mountain Rd, Harpswell, ME 04079, (207) 833-5771 (main) / (207) 387-8833 (direct)). With 5,031 residents, over 4,000, Harpswell is required to enforce the Maine Uniform Building and Energy Code (MUBEC).

  • Maine's adopted 2021 IRC (R703.5) covers wood siding: a water-resistive barrier is required per R703.2, fasteners must penetrate a minimum of 1.5 inches into studs or blocking (R703.3.4), and horizontal lap siding needs a minimum 1-inch overlap (0.5 inch if rabbeted) per R703.5.3. up.codes
  • Beyond the code minimums, a vented rainscreen gap behind wood/cedar siding is common installation practice in Maine's cold, wet coastal climate to let cladding dry and reduce moisture-driven rot — this is standard trade practice referenced in building-science guidance, not itself a numbered MUBEC/IRC mandate, so it should be described to clients as a recommended practice rather than a code requirement. up.codes
  • Maine's Shoreland Zoning Act creates a regulated shoreland zone extending 250 feet (horizontal distance) from the normal high-water line of any great pond, river, or coastal wetland, and 75 feet from certain streams; the Act's stated purposes include protecting buildings and land from flooding/erosion and controlling water pollution, and it governs deck and other structure setbacks and the expansion of nonconforming structures within that zone (specific setback/expansion rules are set at the municipal-ordinance level under the state's model guidelines). maine.gov
  • By Maine law (25 M.R.S. §2373), 'the code must be enforced in a municipality that has more than 4,000 residents' (per the most recent federal census); municipalities at or below that population are not required to adopt/enforce MUBEC but may opt in locally, per the state's own program page: 'All municipalities with a population greater than 4,000 are required, by statute, to enforce the MUBEC. Municipalities with a population under 4,000 may choose to enforce the MUBEC.' mainelegislature.org

How Cardinal Exteriors Handles Cedar Siding in Harpswell

  • With 5,031 residents, Harpswell is over Maine's 4,000-resident line, so the town enforces the statewide Uniform Building and Energy Code (MUBEC) on top of its own permit process.
  • With 29% of Harpswell's housing built before 1960, a real share of that stock predates 1978 as well, which means EPA lead-safe containment is part of cedar siding and shingles on an older Harpswell home more often than not.
  • Harpswell's shoreline, lake or river frontage falls under Maine's Mandatory Shoreland Zoning Act, so we check setback rules before work starts near the water.
  • We file for cedar siding and shingles permits at the Town of Harpswell Code Enforcement Office before work starts, not after.

What cedar siding and shingles involves

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.

Signs it is time

  • 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

What affects the price of cedar siding and shingles

  • 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
