Granite State Metal Roofing is a free matching service, not a contractor. We
connect New Hampshire homeowners with independent local metal roofing
professionals.
Metal roofs fail at their details, not their panels. A leak on a New
Hampshire metal roof almost always traces to a fastener, a flashing,
or a seam under stress from snow and freeze-thaw, and most of those
have real repairs well short of replacement. Granite State Metal
Roofing matches homeowners statewide with independent local
professionals who fix metal instead of only selling new metal.
What actually goes wrong
Fastener back-out. Exposed-fastener roofs live and die by thousands of gasketed screws. Thermal cycling works them loose, gaskets age, and each one becomes a slow drip. Re-fastening with oversized screws and fresh gaskets is the classic repair; wallowed-out holes across the field mean the conversation changes.
Flashing failures. Chimneys, skylights, pipe boots, sidewalls, and valleys. UV-cracked pipe boots and pulled sidewall flashing cause a large share of "mystery" leaks, and each is a component-level fix.
Snow and ice damage. Sliding slabs bend eave trim, tear off gutters, and rip out undersized snow guards. The repair includes asking why the layout let it happen; see snow guards and ice dam protection.
Seam and panel damage. A dropped limb, foot traffic in the wrong spot, or an opened mechanical seam. Individual panels can be replaced and seams re-locked by someone with the matching profile and tools.
Surface corrosion. Scratches through the finish, cut edges, and dissimilar-metal contact points. Caught early this is touch-up and isolation work, not panels.
Repair or replace: the honest line
A useful rule: component problems get repaired, system problems get
replaced. One boot, one bent eave, one panel, a dozen backing-out
screws: repair. Field-wide fastener holes gone oval, finish failure
across whole slopes, or chronic leaks on an undersized system carrying
real snow load: start pricing replacement, because repair money spent
there buys months, not years. The replacement side of that math is at
metal roof replacement,
with statewide cost ranges in the
NH metal roof cost guide.
Either way, the vetting is the same as any roof contract in this
state: written scope, insurance certificate from the insurer, and
references. New Hampshire has no roofing license to check, so the
checking is yours; the
New Hampshire Metal Roofing Guide
carries the full checklist.
Where repair calls come from
Everywhere, but three patterns repeat: aging exposed-fastener barn and
ranch roofs around
Concord
and the farm towns, snow-damage calls from the
White Mountains,
and camp roofs in the
Lakes Region
that went unwatched all winter (seasonal owners have their own page:
lake house and camp roofing).
How to Vet a Roofer in New Hampshire (There Is No License to Check)
New Hampshire issues no state contractor or roofing license and no
contractor registration of any kind. The
Office of Professional Licensure and Certification
licenses electricians, plumbers, gas fitters, fuel oil, and mechanical
trades only. That puts the checking on you, and these five checks do the
job a license would:
A written contract, every time
Get the full scope, price, and schedule in writing before work starts. On residential jobs over $5,000, New Hampshire law (RSA 359-G) requires contract language about the state dispute-resolution process for construction defects. A roofer who knows that statute works here for real.
A certificate of insurance, from the insurer
Ask for a certificate of general liability insurance sent directly from the insurance agent or carrier, not a photocopy. Uninsured roof work puts the claim on your homeowner policy.
Manufacturer system certification
Standing seam panel manufacturers train and certify installers on their systems, and their strongest warranties often depend on certified installation. Ask which system is being quoted and who holds the certification.
Lien awareness
Under New Hampshire law, subcontractors and suppliers can place a mechanics lien on your property if the contractor does not pay them. Ask for lien waivers or proof of payment on larger jobs.
References from standing seam jobs
Not roofing references, standing seam references. Ask for two or three past customers with the same panel system, and call at least one.
Three questions worth asking
Which panel system are you quoting, and are you certified on it?
Will your insurance agent send me a certificate of insurance directly?
Does the contract include the RSA 359-G notice this job size requires?
Not necessarily. Fastener back-out is the signature aging pattern of exposed-fastener roofs, and one round of re-fastening with larger-diameter screws and new gaskets is a routine repair. When the holes themselves have wallowed out across the field, replacement math starts to win; an honest assessment tells you which side you are on.
Can one damaged standing seam panel be replaced?
Often yes. Panels are individual components, and a professional with the matching profile can replace one, though weathered color around a new panel will read slightly different for a while. Seam damage near flashing details is more involved than field damage.
Is caulk a legitimate metal roof repair?
As a permanent fix, no. Sealant has a place inside proper details, but a repair whose entire content is surface caulk is a season-long patch that traps water behind it as it fails. Ask what the water path is and what physically closes it.
