What drives the price in Gorham

Farmhouses and capes in the village and along the older road frontages, large 1990s–2010s subdivisions toward South Gorham and Little Falls, and student-adjacent rentals near the university. The subdivision stock is now old enough to be hitting first-generation roof, siding, and kitchen replacement.

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 Gorham

Authority: Town of Gorham Code Enforcement Office

Building permit for additions, structural work, and decks, with zoning review on setbacks. Many properties are on private well and septic, so bedroom-count changes require septic capacity sign-off. Shoreland zoning applies along the Presumpscot and at Little Sebago.

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 Gorham

Exterior work runs April through November. Inland Gorham freezes a little earlier than the coast, so excavation and foundation work should be scheduled with October in mind.

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 Gorham 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

Roof replacement in Gorham — 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.
