New Hampshire permit-fee context
Manchester + Nashua mid-tier; rural towns often flat-fee residential or no permit for owner-built outbuildings.
Why roofing? Single re-roof permit, low fee in most states. Florida/HVHZ markets add hurricane-rated inspection fees.
What this fee does NOT include
- Plan-review service fees (typically 0.5–1% of cost, separate line)
- Per-trade fees (plumbing, electrical, mechanical — $50–$200 each)
- State-level surcharges (FL DBPR, NJ DCA, OR BCD, etc.)
- Contractor's filing/processing fee
Rule of thumb: budget 1.5–2× the base permit fee for the all-in cost.

FAQ — Roofing permits in New Hampshire
How much is a roofing permit in New Hampshire in 2026?
On a typical $12,000 roofing project in New Hampshire, the statewide median permit fee runs $72 — about 0.60% of project cost. Major metros run higher: Manchester $86, Nashua $83, Concord $72. Manchester + Nashua mid-tier; rural towns often flat-fee residential or no permit for owner-built outbuildings.
Why is the fee higher in major New Hampshire metros?
Each New Hampshire city/county sets its own multiplier on top of the state base rate. Manchester runs 1.2× because of stricter plan review + structural review + energy-code overhead. Concord sits lower (1×) because of less plan-review depth + simpler intake. Rural counties in New Hampshire often have flat-fee schedules below even the lowest metro.
What's included in the permit fee vs. what's billed separately?
The permit fee covers the building department's intake + base review. NOT included: plan-review service fees (often a separate line, 0.5–1% of project cost), per-trade fees for plumbing/electrical/mechanical (typically $50–$200 each), and any state-level surcharges (FL adds DBPR 1.5%, NJ adds DCA, OR adds 12% BCD surcharge). Your contractor's filing fee is also separate. Budget 1.5–2× the base permit fee for the all-in cost.
Can I skip the permit and save the fee?
Don't. Working without a required permit fails any future resale inspection (the buyer's inspector WILL flag it), voids your homeowner's insurance for any related claim, and triggers retro-permitting fines that are typically 2–3× the original fee. New Hampshire treats unpermitted roofing work as a separate violation under state building code. The "savings" become a $1,500 problem at resale on a $500 fee.
