Cedar Siding & Shingles in Topsham, Maine

Census estimates put Topsham's median home built around 1980, with about 12 percent of the housing predating 1940 and roughly 26 percent predating 1960. The town's oldest houses cluster along the Androscoggin River near downtown and in the Pejepscot village area, where mill-era homes date back to the 1800s. Away from the river, Topsham's housing spreads into a much larger share of capes, colonials and contemporary homes built from the 1970s onward, as the town grew alongside Brunswick and the Route 196 commercial corridor into a broader mid-coast residential center.

The Androscoggin River, the Cathance, Little and Muddy Rivers, and Merrymeeting Bay give Topsham a lot of river and tidal frontage for an inland town, and low-lying areas near that water see higher humidity and occasional flood exposure that a house further up the hill doesn't face. Winters bring the usual Maine freeze-thaw cycling and snow load, and older, less-insulated homes near downtown and Pejepscot are prone to ice damming at the eaves in a hard winter. Topsham's location, a few miles from the open coast, means less direct salt-air exposure than towns like Bath or Harpswell, though wind off Merrymeeting Bay still matters for riverside properties.

Building permits in Topsham go through the Code Enforcement Office, a Division of Planning at Town Hall on Main Street, covering siding, roofing, window and deck work. Topsham maintains its own Historic District and Commission, separate from Code Enforcement, and any exterior work inside the town's local historic district near downtown needs that commission's review before work starts. Properties along the Androscoggin, Cathance, Little or Muddy Rivers, or near Merrymeeting Bay, fall under Maine's Mandatory Shoreland Zoning Act, which can affect how close to the water new construction or rebuilding may sit.

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
