Licensing Requirements
New Hampshire does not require state-level licensing for roofing contractors. However, Nashua requires business licensing through the City of Nashua. Roofers must hold valid Home Improvement Registration through NH Department of Safety if performing work over $500. This registration requires: proof of liability insurance ($1M minimum), written contract compliance with NH RSA 358-A, and registration fee of $150 per two years. No state exam required, but federal OSHA 30-hour card and manufacturer certifications (shingle, metal, etc.) are industry standard and expected by most commercial clients.
Permit Requirements
Nashua Building Department requires roofing permits for: full roof replacement, structural modifications, or work exceeding $1,500 valuation. Permit application fee is $50-$150 depending on project scope. Permits typically issued within 5-7 business days. No permit required for repairs under $1,500 or simple maintenance. Roofer must obtain Certificate of Occupancy or final inspection sign-off before customer acceptance.
Inspection Schedule
Initial building permit inspection required before work begins (verification of contractor credentials and insurance). Final inspection mandatory upon roof completion—inspector verifies material installation per code, proper flashing, ventilation compliance, and structural integrity. Re-inspection may be triggered if initial fails. Timeline: inspections typically scheduled within 2-3 days of request; final sign-off needed before invoice payment.
Insurance Minimums
New Hampshire requires minimum $1,000,000 general liability insurance for roofing contractors performing work over $500.

About This Market
Nashua's roofing market is steady and competitive. You've got roughly 65 licensed establishments across New Hampshire, and Nashua—as the largest city in the state—captures significant share. Demand is driven by aging housing stock (many homes built 1970s-1990s hitting replacement cycle), spring/fall storms, and seasonal weather damage. Asphalt shingle jobs dominate residential; metal roofing and commercial work are growing segments. Material costs fluctuate with lumber and steel; labor runs $30.69/hour median statewide, but Nashua contractors typically bill $45-65/hour all-in. Competition is moderate; you can't compete on price alone. What matters is reputation, response time, and warranty backing. Winter slowdown is real—ice dams, snow removal contracts, and roof inspections are your bread and butter November through February. Here's what you need to know to operate legally and profitably in Nashua: New Hampshire doesn't require state roofing licenses, but don't let that fool you—you still need Home Improvement Registration for any job over $500, proof of $1M liability, and full compliance with contract law under RSA 358-A. Nashua adds a municipal business license layer. Permits are required for replacements and structural work; budget 5-7 days for approval. Your real barriers are insurance, inspector relationships, and material supplier accounts. Get certified by major shingle and metal manufacturers—it's what wins commercial bids and protects warranties. Peak season March-October means book crews now and manage capacity aggressively. Winter is survival mode; focus on inspections, maintenance contracts, and ice dam removal. Establish relationships with local building inspectors early—they move jobs faster if they know and trust you.
