Asphalt Shingle Roofing for Sebago homes

Architectural asphalt shingles are the practical re-roof for most year-round houses in Sebago, from 1970s ranches to the homes built since 2000 on large lots along the main roads. The heavier laminated shingles look better and hold better in wind than the three-tab shingles many of these roofs started with, and they cost less than metal or cedar, which matters when a farmhouse, ell and barn all need roofing in the same season.

Winter decides whether a shingle roof lasts. The International Residential Code, on which Maine's building code is based, calls for an ice barrier underlayment at the eaves wherever there is a history of ice forming there, and given the snow Sebago gets, it is worth insisting on, along with membrane in valleys, around chimneys and at roof-to-wall joints. Because the town does not require a permit for roofing, nobody from the town inspects that detail, so ask to see it before the shingles go on. Drip edge, starter courses and the manufacturer's nailing pattern determine the wind rating the roof actually reaches. Low-slope porch roofs need a membrane rather than shingles.

How an Asphalt Shingle Roof System Works

  1. Roof deck — plywood or OSB sheathing the whole system is fastened to
  2. Ice-and-water shield — a self-sealing membrane at the eave, the spot most likely to see an ice dam
  3. Synthetic underlayment — a water-resistant layer under the shingles across the rest of the field
  4. Shingles — the visible, weather-facing layer, lapped to shed water down the slope
  5. Ridge vent — exhausts warm, moist attic air while a soffit vent below draws in fresh air

Sebago housing at a glance

Census estimates count about 1,520 housing units in Sebago, with a median year built of 1975, older than neighboring Naples. About 17 percent predate 1940 and roughly 36 percent predate 1960. Another 19 percent went up between 1960 and 1979, about a quarter between 1980 and 1999, and about 20 percent in 2000 or later. Some 85 percent are single-family detached houses, and about 89 percent of occupied homes are owner-occupied. Nearly 600 units are held for seasonal use. The town's 2006 comprehensive plan found that most homes along Sebago Lake, Peabody Pond and Barker Pond were seasonal while year-round houses sat away from the water, noted a steady conversion of camps to year-round use since 1991, and counted mobile homes at about 13 percent of the stock, mostly on individual lots rather than in parks.

Weather and exposure in Sebago

Sebago is inland lake and hill country, so salt air is not a factor; snow and cold are. The National Weather Service station in nearby Gray records about 84 inches of snow in a normal year, with roughly 20 inches in each of January and February. Elevation adds to the exposure here: Sebago Center sits about 450 feet above sea level, and homes on the slopes toward Douglas Mountain sit higher still. Along the shore, Sebago Lake freezes over completely only every few winters, so wind has miles of open water to build across before it reaches the west-shore camps, and the lake area is known for sudden weather changes in every season. Wooded lots throughout town keep walls and decks shaded and slow to dry.

Permits and design review in Sebago

Permits are handled by the Sebago Code Enforcement and Planning office at 406 Bridgton Road on Route 107, where the Code Enforcement Officer also serves as building inspector and is often out on site visits from noon to 3 p.m. The town's permits page lists building permits, shoreland zoning permits and permit-by-rule forms, and states that no permit is needed for roofing or exterior painting. Siding and window work should be confirmed with the office, and a new deck should be expected to need a building permit. Land within 250 feet of Sebago Lake or a great pond falls under shoreland zoning, which has its own permit form.

Codes & Permits for Asphalt Shingle Roofing in Sebago

In Sebago, exterior-work permits come from the Sebago Code Enforcement & Planning (406 Bridgton Road (Route 107), Sebago, ME 04029, (207) 787-2457). Sebago sits at or under the 4,000-resident line where MUBEC enforcement is a local option rather than a state mandate.

  • Maine's adopted 2021 IRC ice-barrier rule (R905.1.2) specifically names asphalt shingles among the roof coverings requiring an ice barrier extending from the lowest roof edge to at least 24 inches inside the exterior wall line (36 inches along the slope on roofs 8:12 or steeper), using two cemented underlayment layers or a self-adhering polymer-modified bitumen sheet. up.codes
  • Reroofing over existing asphalt shingles in Maine is capped at one existing layer before a full tear-off is required, per R908.3. 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 Asphalt Shingle Roofing in Sebago

  • Maine's code allows at most one existing layer before a full tear-off is required, so on an architectural asphalt shingle roofing job in Sebago we check what's already up there before writing the proposal.
  • Maine's ice barrier rule (R905.1.2) applies in areas with a history of ice damming, which covers Sebago — the membrane runs from the eave to at least 24 inches inside the exterior wall line on every roof we do here.
  • Because Sebago has coastal, lake or river frontage, Maine's Mandatory Shoreland Zoning Act may apply to work close to the water, which can affect setbacks on a rebuild.
  • Sebago, at 2,073 residents, sits under the population line where MUBEC enforcement is a state requirement — the town may still choose to enforce it locally, and the permit process applies regardless.
  • We file for architectural asphalt shingle roofing permits at the Sebago Code Enforcement & Planning before work starts, not after.

What architectural asphalt shingle roofing involves

Architectural (dimensional) asphalt shingles are the most common roof in Maine for good reason: they are affordable, they come in many colors and textures, and a good system handles snow, ice and wind well. Several projects on this site used CertainTeed Landmark shingles. What separates a long-lived shingle roof from a short-lived one is mostly underneath: ice and water protection at the eaves, correct nailing, and balanced ventilation.

  • Tear-off to the deck and sheathing repair where needed.
  • Ice and water shield at eaves, valleys and around penetrations; underlayment over the rest.
  • Starter strip and drip edge at the edges, then shingles nailed in the manufacturer's nail zone.
  • Step flashing at walls, new pipe boots, and chimney flashing as needed.
  • Hip and ridge caps over a ridge vent, balanced with intake at the soffits.

Signs it is time

  • Granules washing into the gutters and bald patches on the shingles
  • Shingles that curl, cup, or lift in wind
  • Leaks around chimneys, vents or skylights
  • Moss or dark streaking on shaded slopes

What affects the price of architectural asphalt shingle roofing

  • Roof area and pitch
  • Shingle line and color
  • Layers to tear off and deck repairs
  • Flashing and ventilation work
  • Number of valleys, dormers and penetrations
