Roof Replacement Cost in Maine (2027 Price Guide)
Adjust the house size or the roof slope in Maine
Not sure of the pitch? Most ranch homes sit low; a roof you cannot walk on, such as 9/12 and up, adds safety gear and labor. This page starts Maine at 7/12.
Our model puts a new asphalt roof in Maine at $10,770 to $16,420, based on a typical 1,680 sq. ft. single-story house. The job we priced has 20.6 squares of roofing (2,058 sq. ft.) on a 7/12 slope; removing one existing layer, labor and materials are all counted.
Divide it out and the installed rate is $638.16 per square; a square is the hundred square feet roofers quote by. Thicker 50-year architectural shingles raise the job to $11,970 to $18,250, and the cheapest metal choice, steel shingles, begins near $23,180.

Price per Year of Roof
The real cost of a roof is price divided by the years it lasts. Hover a bar: metal costs more up front and less per year.
Service lives follow the climate-bell model above (asphalt peaks in moderate regions; metal assumes correct installation); prices are the Maine estimates above.
The Line Items Behind a Maine Roofing Bid
When two quotes for the same house are far apart, the gap is usually scope. Here is what each common variable is worth on the 20.6-square roof above:
- Old shingles. Removing the existing layer accounts for about $3,150 of the price. A hidden second layer adds roughly $2,040 more.
- Roof shape. When every side of the roof slopes down to a gutter (a hip design), add close to $1,300 over a two-sided gable. Plenty of dormers and valleys raise the add-on to about $2,200.
- Building height. Same roof, two stories up: about $940 more, mostly labor and safety staging.
- Skylights. Swapping or adding a skylight costs around $390 each at Maine rates.
- Bad wood. Damaged decking is the most common mid-job extra. Agree on a price per sheet before work starts.
- Trim items. Chimney flashing, pipe boots, ridge vents and drip edge may or may not be in a bid. Gutters usually are not - the gutter cost calculator prices them.
- Paperwork. Local permit fees and dumpster rental vary; ask each roofer to list them rather than add them later.

Figures cover the 7/12 roof above (2,058 sq. ft.) at Maine prices; add gutters, skylights and any deck repairs separately.
Ask each bidder to fill in the same list: tear-off layers, underlayment, ice barrier, flashing, vents, decking rate, permit. Gaps in that list explain most low bids.
How Maine Weather Ages a Roof
Region 1 on the map, Maine sees average summer highs near 79°F and winter readings from about 25°F by day to 6°F at night. Local terrain shifts these numbers. Below are the stresses that matter most for a Maine roof, and what to ask for because of them.
Ice dams. These form when a warm attic melts snow that refreezes at the eaves, trapping water that backs up under the roofing. Two fixes work together: self-adhering ice barrier at the edges and a well-sealed, well-insulated attic. Compare costs with the attic insulation calculator and roof heat cable calculator.
Heavy snow. Weeks of snow cover keep the roof wet and loaded. A sound deck, tight fastening and a steeper pitch all help; metal sheds snow fastest.
Coastal exposure. Salt spray eats ordinary steel. Stainless or coated fasteners and aluminum flashing last far longer within reach of the sea breeze.
Where Shingles Live Longest: the Climate Bell
Asphalt life peaks in the moderate middle (Region 3) and falls toward BOTH ends of the map above - cold regions destroy shingles with ice dams, hot ones bake them. Note the middle columns: shingles marketed as “lifetime” are good for about 25 real-world years at best - Maine is Region 1. Hover any column.
low pitch holds snow and ice - it costs the most years in cold regions
Planning figures from our climate model, for ventilation-correct installs - a baked, unvented attic can take years off any column. Pitch adjusts the asphalt columns only; metal sheds snow at any sane pitch.

Maine Metal Roof Cost
Most metal bids in Maine fall into one of the types below. Each line is priced for a typical 1,680 sq. ft. single-story house, the same way our metal roof calculator does it.
- Standing seam: $30,900 to $47,100. One panel covers the whole run from the ridge down to the gutter, so water has almost no joints to find. Roofers like it on low pitches and simple gables. The premium over architectural shingles here is roughly $23,080.
- Steel shingles: $23,180 to $35,330. Aluminum shingles: $25,630 to $39,070. The look of a regular roof with the life of metal. These pieces work on steep or complicated roofs. Steel resists dents; aluminum resists corrosion.
- Stone-coated steel: $31,550 to $48,090. Steel panels covered in crushed stone and shaped like clay tile or wood shake. The texture hides hail marks and softens rain noise.
- Copper: custom quote only. A copper roof is hand work by a sheet-metal specialist, and it is priced far above standing seam. It never needs paint and weathers to a green patina. Few homes cover the whole roof with it; dormers and entry roofs are the usual places.
Snow slides off metal before it can melt and refreeze at the eaves, so ice dams have little chance to form. No ice dam means no water backing up under the roof and no rotting eaves, which is a big reason metal lasts so long here. Add snow guards over doors and walkways.
Owners who stay put get the most from metal, because the long service life is where the savings sit. Want a firmer metal number? Try the metal roof calculator with your measurements.

Best Season for a New Roof in Maine
Cold winters (highs around 25°F) push most re-roofing into the warm months, when shingle seal strips can bond. Get bids in late winter to secure a spring or summer slot.
Pricing Low-Slope Roofs in Maine
A flat roof the size of this home's 1,680 sq. ft. footprint would run, in Maine:
- EPDM rubber: $14,680 to $19,070. Think of a heavy inner tube spread over the deck. The seams are glued, not welded, and over time they are its weak spot. It earns its place on small, simple roofs and in cold places.
- TPO, 60-mil: $12,640 to $16,410. The bright white membrane on many new commercial and home flat roofs. Hot-air welded seams turn the sheets into one skin. Pick it for a sunny roof over living space.
- PVC, 60-mil: $15,280 to $19,840. The premium white membrane: welded seams, a strong fire rating, and good resistance to puddles and chemicals. It fits roofs that carry foot traffic or hold water after a storm.
Price order in Maine: TPO first, PVC last, with EPDM between them. Both insulation board and old-layer removal are in the numbers. Per square foot, small flat roofs cost noticeably more than large ones. Water that pools and freezes on a flat roof opens seams over time. Re-roofing is the moment to fix low spots with tapered board. Run the flat roof calculator to match a specific membrane and drain layout.
Snow load and slow melt are the test in Maine. Any of the three can pass it if the seams are done right and the water has a clear path off the roof. Ask how the bid handles drains and low corners.

Maine Roofing Questions
How long does a re-roof take?
A typical 20.6-square asphalt job takes from one day to a few, depending on layers, pitch and weather. Metal and cut-up roofs take longer. Any section left open overnight should be covered.
Can I file an insurance claim for a new roof?
Covered: hail, wind, fallen trees. Not covered: age and wear. With asphalt at $10,770 to $16,420 in Maine, it pays to read your roof settlement terms now, not after a storm.
How do roofers measure a roof in squares?
Take the footprint (1,680 sq. ft. here) and adjust for pitch (7/12): about 20.6 squares, or 2,058 sq. ft., counting overhang and waste. Get the square count on every quote.
Is a roofing permit required in Maine?
Often yes. Most local building departments want a permit for a full replacement. The contractor normally handles it - ask to see it before work starts.
