Roofing contractors in Scarborough, ME
Scarborough is the fastest-growing town in Greater Portland, and that demand shows up in contractor availability more than in hourly rates. Crews are booked deep, so the practical cost of waiting — or of paying for an off-season start — is often the real variable here.
Our Haus isn't a contractor directory. We give you the local cost math, the permit reality, and the paperwork tools — the scope, the proposal comparison, and the vault your records live in.

What drives the price in Scarborough
A wide spread: 1960s–1990s subdivisions inland, older farmhouse and cottage stock in Dunstan and Oak Hill, and coastal homes at Higgins Beach, Pine Point, and Prouts Neck that sit in flood and shoreland zones. Beach-area properties carry elevation, flood-vent, and salt-exposure requirements that inland quotes never include.
- Ice-and-water coverage
- New England code and good practice call for ice-and-water shield well past the interior wall line at the eaves. Some bids cover the first course only. That difference is invisible on a quote total and very visible in February.
- Pitch and stories
- Steep pitches over 8:12 need staging and fall protection, and a three-story house adds setup time. Both raise labor materially.
- Layers to remove
- Two or three existing layers mean more tear-off labor and more disposal weight. Ask whether the bid assumes one layer and what happens if there are two.
- Deck condition
- Sheathing replacement should be a per-sheet unit price in the contract, not a surprise. Older plank decking sometimes needs full re-sheathing.
- Ventilation
- Ridge vent plus adequate soffit intake is what keeps the roof deck cold and prevents ice dams. A bid that adds a ridge vent without confirming intake is not solving the problem.

Permits and rules in Scarborough
Authority: Town of Scarborough Building Inspections and Code Enforcement
Additions and structural work need a building permit plus zoning review. Coastal and marsh-adjacent parcels — a large share of the town — fall under shoreland zoning and FEMA flood-zone rules, which can dictate elevation and construction method, not just approval. Confirm the flood zone before design.
Maine contract and licensing rules
Maine requires a written contract for home-construction or repair work over $3,000. The contract must include the contractor's name and address, the work and materials, the total price, a payment schedule, start and completion dates, a warranty statement, and notice of the state's contractor-dispute mediation program. Maine does not license general contractors, so verify insurance directly with the carrier.
Timeline and season in Scarborough
Coastal exterior work concentrates from late April through October. Summer traffic and beach-season parking around Pine Point and Higgins Beach genuinely slow deliveries and crew access, which is why some contractors price shoulder-season work lower.
Typical duration: 1–4 days on site for a typical single-family.

What's included — and what usually isn't
A roof replacement in New England is as much about ice and water management as it is about shingles. The shingle line item is the easy part to compare between bids; the underlayment, ice-and-water coverage, flashing, and ventilation details are where bids actually differ.
Typically included
- • Tear-off and disposal of existing roofing layers
- • Deck inspection and replacement of damaged sheathing (usually a unit price)
- • Ice-and-water shield at eaves, valleys, and penetrations
- • Synthetic underlayment across the field
- • Drip edge, step flashing, and counter-flashing at walls and chimneys
- • Shingles, ridge cap, and ridge or static ventilation
- • Pipe boots and any skylight flashing kits
- • Site protection, magnetic nail sweep, and cleanup
Usually excluded
- • Chimney masonry repair or rebuilds
- • Gutter replacement, unless separately listed
- • Structural repair to rafters found under a rotted deck
- • Interior ceiling repair from prior leaks
What a complete Scarborough estimate spells out
- • Total roof area in squares and the number of existing layers assumed
- • Shingle manufacturer, product line, and warranty type (material vs. system)
- • How far ice-and-water shield extends at eaves and valleys, in feet or courses
- • A per-sheet unit price for sheathing replacement
- • Flashing approach at chimneys and walls — new step flashing or reuse
- • Ventilation plan, including soffit intake
- • Proof of workers' compensation coverage for a crew working at height

Check my quoteRoof replacement in Scarborough — common questions
How do I compare two roofing bids that are thousands apart?
Compare the underlayment and flashing lines, not the shingle brand. Ice-and-water coverage, whether step flashing is new or reused, the sheathing unit price, and the ventilation plan explain most of the spread.
Can a roof be replaced in winter here?
It can be done when a roof is failing, but asphalt shingles need warm surfaces to seal. Cold-weather installs generally require hand-sealing tabs and cost more. Schedule April through November when you have the choice.
