Is there any contractor license to verify in New Hampshire?

No roofing one. RSA Title XXX, the state occupational licensing title, lists 98 chapters and none of them licenses a roofer, a general contractor or a home improvement contractor. It does license electricians, plumbers, alarm installers and gas fitters, so a trade working on part of your project can still hold a real state credential.

What is RSA 359-G and what does it do for me?

It is New Hampshire’s residential construction defect dispute resolution law, not a licensing scheme. It sets up a notice-and-opportunity-to-repair process before a defect lawsuit, and RSA 359-G:7 requires the contractor to give the owner conspicuous written notice of that right on a residential contract over $5,000.

Which metal roofing brand should you choose?

This site ranks no brand and endorses none. What matters more than the badge on the panel is whether the company quoting it holds that manufacturer’s own installer certification for the exact system, because the strongest material and weathertightness warranties are usually written to require certified installation.

How do you know if a metal roofing quote is fair?

Compare the same roof, not the same total. Published national guides disagree by roughly a factor of four on standing seam, so a single quote proves nothing. Ask every bidder to name the panel system, gauge, finish, snow retention layout, deck repair rate and payment schedule, then compare those lines against each other.

What should I do if a roofer claims to be "NH licensed"?

Ask exactly which license they mean. If the answer is an electrician or gas fitter card for a crew member, that is a real credential for that trade and it is checkable at the OPLC license lookup. If the answer implies a state roofing or contractor license, Title XXX creates none, and a credential pitch built on one is reason to slow down.

Does hiring through this site change what I should check?

No. Granite State Metal Roofing is a free referral service, and the professional who quotes your roof through it should pass the same five checks as anyone else: written contract, insurance certificate from the insurer, manufacturer certification, lien waivers on larger jobs, and standing seam references.

How to choose a metal roofing company in New Hampshire

Q: What is the biggest problem with metal roofs?

Detailing rather than the metal. InterNACHI’s inspector training says seams are a weak point in the system, that the areas most vulnerable to wind are panel edges at the peak and eaves and along the rakes, and that any installation relying on a sealant to keep water out needs new sealant applied on a regular basis. Those are the lines to ask a company about.

Choose a New Hampshire metal roofing company on five checks, because there is no state license to look up: a written contract carrying the RSA 359-G notice on jobs over $5,000, an insurance certificate sent by the insurer, the panel manufacturer's own installer certification, lien paperwork on larger jobs, and references from standing seam roofs.

Here is the number that explains why the list looks like that. New Hampshire's occupational licensing title, RSA Title XXX, lists 98 chapters covering everything from electricians to lightning rod dealers, and not one of them licenses a roofer (RSA Title XXX, the chapter table of contents at the New Hampshire General Court, read on 2026-08-23). The verification job is not missing here. It has moved from a government database to your kitchen table, and this guide is the checklist that does it.

Is there a New Hampshire roofing license to check?

No. Read end to end on 2026-08-23, the RSA Title XXX chapter list runs from accountancy to veterinary medicine and creates licensing chapters for electricians (RSA 319-C), plumbers (RSA 329-A and RSA 330), alarm installers (RSA 323-A) and even lightning rod dealers (RSA 323). The word "roof" appears in no chapter title, and no chapter creates a general contractor or home improvement contractor credential. Some directory and marketing sites circulate a claim that New Hampshire registers home improvement contractors above a $1,000 job threshold. That registration is not in the title.

The confusion usually traces to RSA 359-G, which is a residential construction defect dispute resolution law rather than a licensing scheme. It creates a notice-and-repair process before litigation, and RSA 359-G:7, read at the statute on 2026-08-23, says at paragraph I that on a contract "for the construction or improvement of a residence in which the contract amount exceeds $5,000, the contractor shall provide written notice to the owner of the residence of the contractor's right to resolve alleged construction defects before a homeowner may commence litigation". It licenses and registers nobody.

One nuance keeps people honest: individual trades on a roofing job can still hold real state licenses. If your project touches wiring (heat cable circuits, for instance) or gas venting, the electrician or gas fitter doing that part is checkable at the OPLC license lookup. The roofer as roofer is not.

The five checks that replace the license

A written, complete contract. Scope, price, panel system, gauge, finish, snow retention layout, payment schedule, and a per-sheet decking price. On jobs over $5,000, the RSA 359-G notice belongs in it, and a company that includes it unprompted is telling you they work here for real.
A certificate of insurance, from the insurer. Ask the bidder to have their insurance agent send the general liability certificate directly to you. A photocopy from a truck seat proves a policy existed once; a certificate from the agent proves it exists now. Workers compensation is the other half. RSA 281-A:5, read on 2026-08-23, requires an employer subject to the workers compensation chapter to secure that coverage, either by insuring with a carrier licensed to write it in this state or by proving financial ability to pay claims directly, and RSA 281-A:18 says a contractor who subcontracts part of a job "shall bear the liability of the subcontractor" for that compensation "unless the subcontractor has secured the payment of compensation". So ask two questions rather than one: does the company carry it, and does every subcontractor on your roof carry their own?
Manufacturer system certification. Standing seam makers train and certify installers, and their strongest material and weathertightness warranties often require certified installation. Ask which panel system is being quoted and who on the crew holds the certification. This is the closest thing to a license that exists in this market, and it is issued by the party with the most to lose.
Lien awareness. New Hampshire mechanics lien law lets unpaid subcontractors and suppliers reach the property they improved. On larger jobs, ask for lien waivers or proof of supplier payment with the final check. Boring paperwork, real protection.
References from standing seam jobs. Two or three past customers with the same system you are buying, at least one called. Ask one question that matters: what happened when something went wrong?

How can you tell a good metal roofing company from a bad one?

By what they put in writing before you pay anything. A company worth hiring names the panel system, gauge and finish in the quote, prices deck repair per sheet instead of leaving it open, carries the RSA 359-G notice on a contract over $5,000, and answers a detailing question without changing the subject. A company to walk away from quotes a lump sum, will not name the system, and leans on a credential the state does not issue. None of that requires you to know roofing. It only requires you to read the same four lines on every quote.

What questions should you ask a metal roofing company?

Six, and they are all answerable on the phone. Ask them in this order.

Which panel system, gauge and finish are you quoting, and are you certified by that manufacturer to install it?
Will your insurance agent send me the general liability and workers compensation certificates directly?
Do you subcontract any part of this job, and does each subcontractor carry their own workers compensation coverage?
What happens to the price if the deck under the old roof is rotten, and what is that rate per sheet?
How are you detailing the eaves, rakes and valleys, and does anything in this roof depend on sealant to stay watertight?
Who pulls the building permit, and which town office are you pulling it from?

How do you know if a metal roofing quote is too high?

You cannot tell from the total alone, and anyone who says otherwise is selling something. Published national guides disagree by roughly a factor of four on the same job: This Old House, priced from RSMeans data and updated March 2026, puts standing seam at $8 to $39 per square foot installed, which is $7,540 to $39,430 on a 1,000 square foot roof, while Today's Homeowner says $10 to $20 and Bob Vila says $2 to $10. None of those is a New Hampshire quote and none is ours. The usable test is comparability: make every bidder price the same panel system, gauge, finish, snow retention layout and deck repair rate, and the outlier stops being a mystery. The line-by-line version lives in the metal roof cost guide, and what the paperwork has to say is on metal roof replacement.

What is the biggest problem with metal roofs?

Detailing, not the metal, which is why the company matters more than the brand. InterNACHI's inspection training for metal roofs, read on 2026-08-23, says "Seams are a weak point in the system", that "The areas of metal panel roofs most vulnerable to wind are panel edges at the peak and eaves, and along the rakes", and that "Any installation that relies on a sealant to prevent moisture intrusion will need to have new sealant applied on a regular basis". That is national inspector training rather than a New Hampshire rule, and it is exactly the ground a good installer will talk about unprompted. The panel choices behind those details are covered under standing seam metal roofing.

Do online reviews tell you anything about a metal roofing company?

A little, and less than people think. A star average is not a credential, and it says nothing about whether the crew has installed the system you are buying. Read the text instead of the number: a review that names the panel system, describes what happened when a detail leaked, or is written by someone with the same roof pitch and exposure as yours is worth more than 50 five-star lines that could describe any trade. Then run the five checks anyway. This site publishes no ratings and ranks no company.

Red flags with New Hampshire serial numbers

A credential pitch built on a state roofing license or contractor registration. Title XXX creates neither.
A quote leaning on a tax credit or rebate. The federal 25C credit expired at the end of 2025 and NHSaves has no roofing rebate; the cost story should stand without them.
A contract that names no panel system, gauge, or finish. Five words make quotes comparable; their absence is a choice.
Large cash deposits against no materials. Reasonable deposits track material orders; the schedule belongs in writing.

Where this fits in the bigger decision

Choosing the company is one chapter of the whole standing seam decision. The New Hampshire Metal Roofing Guide carries the rest, from snow loads to the owner checklist. The checks matter most where owners manage the job remotely, which is half the Lakes Region. When the checklist is done and you want a name to run it on, the form gets you one free quote from metal roofing contractors in New Hampshire, one homeowner to one professional.
