New siding on a home in Cumberland County, Maine

Siding, Roofing, Windows & Decks in South Portland, Maine

South Portland's houses span more than a century, from the waterfront streets of Ferry Village to post-war neighborhoods and newer homes near the Maine Mall. About a quarter of the city's housing predates 1940, and the city puts extra steps in front of exterior work on those older buildings. Cardinal Exteriors, a family-owned siding, roofing, window and deck company based across the bridge in Portland, put this page together on what matters for South Portland homes.

South Portland homes and what they need

South Portland has about 12,800 housing units, and the American Community Survey estimates a median year built of 1968, two decades newer than Portland across the harbor. About 25 percent of homes predate 1940 and about 45 percent predate 1960. Roughly 16 percent went up between 1960 and 1979, and close to 19 percent date from 2000 or later, a larger share of newer construction than on the peninsula. Owners occupy about 58 percent of occupied homes, and single-family detached houses make up a little over half the stock, with apartments, condominiums and two-family houses filling out the rest. Seasonal homes are rare, only about 100 units. The older waterfront villages hold the city's early wood-frame houses, while the neighborhoods farther inland are largely post-war and later.

Weather and exposure in South Portland

South Portland faces Portland Harbor and the Fore River on its north side and Casco Bay to the east, so houses in Ferry Village, Willard and the streets near Spring Point take salt air and onshore wind, while western neighborhoods near the Maine Mall are more sheltered. The city shares its weather with the Portland International Jetport, whose main runway lies inside South Portland, and the Portland area averages about 69 inches of snow a year, with some winters far lighter or heavier. Nor'easters drive rain and snow sideways against exposed walls, and repeated freeze and thaw loosens caulk, paint and shingles. Near the water, salt speeds corrosion of flashing and fasteners.

South Portland neighborhoods and architecture

South Portland split from Cape Elizabeth in 1895 and incorporated as a city in 1898. Ferry Village is its oldest neighborhood, and Knightville, Mill Creek, Willard, Meetinghouse Hill, Pleasantdale, Ligonia, Redbank and Cash Corner each have their own feel. During World War II its shipyards built 236 Liberty ships. The shoreline holds Fort Preble, established in 1808, Spring Point Ledge Light from 1897, the Portland Breakwater Lighthouse known as Bug Light, and Willard Beach. Inland, the city is home to the Maine Mall, Rigby Yard and the oil terminals along the harbor.

Permits and design review in South Portland

Building permits in South Portland come from Code Enforcement, part of the Department of Planning and Development, which issues permits and conducts inspections for building, electrical and plumbing work. Applications can go through the city's online portal or by email. The city enforces the Maine Uniform Building and Energy Code, based on the 2021 International Residential Code, and a permitted project must make a substantial start within 180 days. Since 2019, a building permit for exterior work on a designated historic property or any structure built in 1940 or earlier may be delayed up to 90 days. Shoreland zoning applies along the harbor and bay.

Roofing in South Portland

  • Roof Replacement in South PortlandSouth Portland roofs take coastal wind, heavy snow and freeze-and-thaw cycles that wear shingles along eaves and ridges.
  • Asphalt Shingle Roofing in South PortlandArchitectural asphalt shingles cover most of South Portland's single-family houses, and for good reason: on the ranches, capes and splits built through the middle of the last century, they give a durable, cost-effective roof with more shadow line than the flat three-tab shingles many of those houses started with.
  • Metal Roofing in South PortlandStanding seam and metal shingle roofs make sense for several kinds of South Portland houses: homes on exposed lots near the bay where wind and salt shorten the life of shingles, low-slope additions and porches, and detached garages or sheds with simple roof lines.

Decks in South Portland
