A Dover, New Hampshire–based roofing and siding contractor serving homeowners across Maine and New Hampshire. Built around one idea: the homeowner deserves a transparent, accurate price, online first or in person, whichever they prefer.
Most homeowners want a real number before they schedule anyone to come out. The measurements that drive a roofing estimate, square footage, pitch, facets, complexity, can be pulled from satellite imagery in under a minute, so we give you a starting price range online first. When you want eyes on the roof, a Nova team member comes out for a free in-home visit and a written proposal.
Nova Roofing & Siding was founded in 2025 in Dover, New Hampshire, with a simple operating premise: instant, accurate online estimates backed by engineered installation standards. Every estimate we generate is a real price range, not a teaser. Every install uses the same architectural shingle system, the same aggressive ice-shield coverage, the same balanced ridge-and-soffit ventilation. No good-better-best games. No pressure to upgrade.
We built this company because we think homeowners deserve clear pricing without pressure, whether they start online or with a visit. The satellite-measured instant estimate is how every online quote on novaroofingsiding.com is generated, and the in-home visit is how we confirm it.
Enter your address and our system pulls live satellite data to measure your roof's square footage, pitch, facets, and wall area. You see a real price range in under 2 minutes, not a guess, not a ballpark based on a phone call.
Start with a satellite-measured estimate online, or schedule a free in-home visit with a Nova team member. Either way, a free on-site inspection confirms the final proposal before any work begins.
We install one roofing system and one siding system, both built to the same specification on every home. Premium underlayment, aggressive ice & water shield, 6-nail shingle patterns, balanced ventilation. No builder-grade shortcuts on any Nova install.
The estimate you see online is the same pricing logic we use internally. No inflated sticker price waiting to be "discounted." What you see is what the work costs.
Our crews are factory-certified installers, which means every Nova roof carries manufacturer system warranties up to 50 years, non-prorated, transferable, and backed by the material manufacturer, not just the contractor.
Institutional financing with fixed terms and no hidden fees. Soft credit check with no impact to your credit score. You can see your approved rate before committing to the project.
