New Hampshire Roofing License Requirements
New Hampshire has NO state contractor licence of any kind - no general contractor licence, no roofing licence, and no state home improvement contractor registration. Only trades bearing directly on life safety (electricians, plumbers, fuel gas fitters) are licensed by the state through OPLC. Roofing is governed purely by local building permits and codes plus ordinary business registration with the Secretary of State.
Do roofers need a license in New Hampshire?
No state roofing license in New Hampshire
No state agency licenses roofers, and roofing is not covered by a broader state contractor credential either.
The rule in detail
- State-level requirement
- No state licence
- Licensing authority
- New Hampshire Office of Professional Licensure and Certification (OPLC)
- Class covering roofing
- No state classification — New Hampshire does not issue a roofing-specific credential.
- Dollar threshold
- Not applicable — there is no state credential for a threshold to apply to.
- Statute or rule
- No contractor licensing statute exists. RSA chapter 310-A, which covers OPLC-administered occupations, licenses professional engineers, architects, land surveyors, natural scientists, foresters, geologists, landscape architects, court reporters, home inspectors, septic system evaluators and doulas/lactation providers - it contains no contractor, general contractor, home improvement contractor or roofing provision.
- Bond
- None published at state level.
- Insurance
- None published at state level.
- Reciprocity
- No published reciprocity arrangement for roofing.
- Public license lookup
- No statewide lookup — check with the city or county issuing the local credential.
Local licensing and permits in New Hampshire
With no state licence, oversight is entirely local: roofers pull building permits from the building department of each city or town where they work, and a handful of municipalities impose their own registration or permit-holder requirements. All businesses operating in New Hampshire must still register with the Secretary of State, and New Hampshire does license electricians, plumbers and fuel gas fitters through OPLC - but roofing and general contracting are not among the licensed trades.
Permitting is a separate system from licensing, and it is almost always local. In New Hampshire, as nearly everywhere in the United States, a full roof replacement is treated by the adopted building code as work requiring a permit and a final inspection, while small repairs are often exempt below a threshold the local code sets. The building department for the city or county where the house sits is the only body that can tell you which side of that line your job falls on.
The two questions are not the same question
Licensing asks whether this contractor is permitted to sell roofing work in this jurisdiction. Permitting asks whether this specific job on this specific building may proceed. A contractor can be perfectly licensed and still be doing unpermitted work, and an unpermitted roof tends to surface at a sale, at a claim, or at a warranty dispute — years later, when it is expensive.
If you are hiring a roofer in New Hampshire
- ●Do not treat “licensed and insured” as meaning anything specific here. With no state roofing credential in New Hampshire, the phrase usually refers to a general business license, which any company can obtain and which says nothing about roofing competence. Ask what license, issued by whom, and check it with that issuer.
- ●Ask for certificates of insurance directly from the insurer or agent. General liability and workers’ compensation both matter, and roofing carries some of the highest comp premiums of any trade — which is exactly why some operators go without. An injury on an uninsured crew can find its way to your policy.
- ●Confirm who is pulling the permit. It should be the contractor, in their own name. An invitation to pull it yourself as the homeowner moves the code liability onto you, and is often a sign the contractor cannot pull it.
- ●Get the scope in writing before any deposit changes hands. Tear-off versus overlay, decking replacement priced per sheet, underlayment and ice-and-water coverage, ventilation, flashing, and who hauls the debris. Most roofing disputes are scope disputes wearing a different hat.
- ●Be careful after a storm. Door-knocking crews follow hail. Before signing anything that assigns your insurance benefits or commits you to a contractor contingent on a claim being approved, read it twice and check the cancellation terms.
If you are a roofing contractor working in New Hampshire
New Hampshire does not put a roofing credential in your way at state level, which makes the local layer the operative one. Requirements change at the city and county line, and the practical discipline is to check registration and permitting with each building department you intend to work in before you bid, not after you have signed.
Two consequences of getting this wrong are worth knowing regardless of the state. Contracting without a required credential is commonly a misdemeanour offence, and in most states an unlicensed contractor cannot enforce the contract or file a mechanic’s lien — so an unpaid job simply stays unpaid, with no legal route to collect. Confirm your position with the board before you bid, not after.

Note on this entry
IMPORTANT CORRECTION - several commercial contractor-licensing websites claim New Hampshire requires a 'Home Improvement Contractor (HIC) registration' for residential work over $1,000 under RSA 310-A:188. This is FALSE and should not be repeated. The official New Hampshire statute table of contents at gc.nh.gov shows RSA 310-A covers engineers, architects, surveyors, home inspectors and similar professions with no contractor provision, and section 310-A:188 sits inside the HOME INSPECTOR sequence and was repealed by 2024, ch. 327, sec. 210(I), effective July 1, 2024. There is no New Hampshire home improvement contractor registration program.
Checked August 2026. Licensing rules change — dollar thresholds get raised, boards get reorganised, and statutes get amended mid-session. This page is a research summary, not legal advice, and it is not the authority on anything.
The authority is New Hampshire Office of Professional Licensure and Certification (OPLC). Before you sign a contract or bid a job, confirm the current rule with them directly.
