How Much Does a New Roof Cost in New Hampshire in 2026
No survey measures a New Hampshire roof alone. Zonda Media’s Remodeling 2025 Cost vs. Value Report (www.costvsvalue.com) gives $35,701 as New England’s asphalt-shingle roof replacement average, drawn from Boston, Hartford and Portland, Maine. Granite State roofers earned $30.69 an hour in May 2025 (U.S. mean: $27.95), and no state license exists for them.
A New England number with no New Hampshire city behind it
That survey spans 28 projects in 119 markets nationwide. Its New England page names three sample cities: Boston, Massachusetts; Hartford, Connecticut; and Portland, Maine. Manchester, Nashua and Concord are absent, so read these as a regional yardstick, not a local quote.
Asphalt-shingle roof replacement, New England: job cost $35,701, resale value $22,346, 62.6% recouped. The same project’s national average is $31,871 (67.5%). Metal roof replacement, New England: job cost $56,282, resale value $21,904, 38.9% recouped. National: $51,865 (50.1%).
Both are the report’s own defined projects; neither captured page says how big the priced roof is or which shingle it uses.

Granite State roofer pay, May 2025
The Bureau of Labor Statistics’ May 2025 occupational survey counted 270 wage-and-salary roofers in New Hampshire. Their mean pay was $30.69 an hour ($63,820 a year); the median was $28.76. For the whole country the mean was $27.95 ($58,140) and the median $26.65. Self-employed roofers are left out, and this is pay, not a price: labor is one input of a bid.
No license to check, and a study committee due to report November 1
The Attorney General’s office put it plainly in a March 10, 2022 consumer alert: “In New Hampshire, contractors do not need to be licensed.” The same alert lists warning signs, among them a contractor who “asks for a down payment that is over 50% of the final cost, or asks for full payment before the job is completed.”
That may change. Senate Bill 523, now 2026 Laws chapter 258 (approved July 2, 2026, effective the same day), created a legislative committee to study “a statewide registration system for residential builders and contractors.” Its findings are due “on or before November 1, 2026.” Until a law follows, there is no state roster to search.
What you can verify is insurance. In a February 19, 2026 advisory the New Hampshire Insurance Department told owners to ask for a certificate from the contractor’s insurer or agent and to call that insurer to confirm the policy is in force. It added that “Contractors with one or more employees are required under New Hampshire law to carry workers’ compensation insurance.”
A contract signed at home: RSA 361-B
If a roofer sells you a job of $150 or more anywhere other than the seller’s permanent place of business, RSA 361-B:2 lets you cancel “any time prior to midnight of the third business day after the date of this transaction.” You cancel by written notice mailed to the seller (the statute prefers certified or registered mail) or by handing back the goods in person. Under RSA 361-B:2, I(b) the seller then has 15 days to return every payment, any trade-in and any note you signed.
The part that matters for roofing is I(b-1). If the crew has already done work that “physically altered the property” inside that window, you still get back all the money, and the seller “shall not be entitled to deduct the value of such services or work.” Where the house can reasonably be put back, you may demand full restoration instead of the refund. A violation counts as an unfair or deceptive practice under RSA 358-A.
When the new roof leaks: a 60-day notice comes first
RSA 359-G covers defect disputes between homeowners and residential contractors. Before suing, you serve the contractor with a written notice of claim “no later than 60 days before initiating an action.” The contractor has 30 days to offer a settlement, propose an inspection or reject the claim. If it stays silent, rejects the claim outright, or will neither repair nor settle, you may sue at once; the two sides may also agree in writing to a different process. A suit filed without the notice is stayed, on a party’s application, until you comply.
The state code changed on July 1, 2026
New Hampshire has one building code, and under RSA 155-A:2 it governs the “alteration, renovation, rehabilitation, repair” of existing buildings as well as new ones. House Bill 1159, enacted as 2026 chapter 49 (approved May 8, 2026, effective July 1, 2026), rewrote RSA 155-A:1, IV so that it adopts the International Residential Code 2024 in place of the 2021 edition; the energy code stays at the 2018 IECC. For six months after a new code takes effect, a permit applicant may show compliance with the old edition or the new one, “but not a combination of the 2 codes.”
Permits and fees belong to the municipality. RSA 155-A:2, III reserves them to towns and cities that have set up local enforcement, and RSA 155-A:3, II bars local changes to the code’s technical requirements. Where a town has no enforcement agency, the state fire marshal may enforce the code only “upon written request of the municipality.” Call your town’s building official before the tear-off starts.
Questions New Hampshire owners ask
Can I look up my roofer’s state license?
No. There is none to look up; chapter 258 of 2026 only set up a study of registration. Ask for the certificate of insurance and confirm it with the insurer.
The crew started the day after I signed at my kitchen table. Can I still back out?
Yes, until midnight of the third business day. Under RSA 361-B:2, I(b-1), work already done does not reduce your refund.
My house is in a historic district. Does the state code override the district’s rules?
No. RSA 155-A:2, VIII says buildings must also comply with local land use restrictions, naming “historic district laws or ordinances” among them.
Can my town write its own roofing standards?
Not technical ones. RSA 155-A:3, II states: “No amendments to the technical requirements of the state building code are permitted.” Towns keep the permit process and the fees.
