A Dover, New Hampshire–based roofing and siding contractor serving homeowners across Maine, New Hampshire, and Vermont. Built around one idea: the homeowner deserves a transparent, accurate price without a sales rep in their living room.
New England homeowners have been told for decades that getting an accurate roofing or siding estimate requires letting a salesperson into their home for two hours. We disagree. The measurements that drive a roofing estimate — square footage, pitch, facets, complexity — can be pulled from satellite imagery in under a minute. The rest is pricing logic that doesn't require a living-room pitch.
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 the industry has been coasting on a high-pressure sales model that takes advantage of homeowners at a stressful moment. The satellite-measured instant estimate is our alternative — and it's how every quote on novaroofingsiding.com is generated.
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.
You can complete your entire estimate online without speaking to a sales rep. A free on-site inspection happens only after you decide you want to move forward — not before. Your time is respected from the first click.
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.
