New Hampshire homes endure a punishing mix of heavy precipitations and intense temperature swings. This rapid freeze and thaw pattern destroys basic asphalt shingles and leads directly to water penetration around the roof line.
At Nova, we build defensive exterior systems for New Hampshire. We heavily prioritize extreme thermal-shock resistant underlayments alongside ridge and soffit air-exchange strategies that naturally regulate attic temperatures. This actively prevents the very melting cycles that trigger winter leaks across NH.
As elite factory-certified installers, we provide our NH clients with comprehensive non-prorated system protection.
A specialized NH Project Manager will oversee your complete build from permit acquisition to the final driveway sweep.

Dover sits on New Hampshire's Seacoast, where coastal salt air, nor'easter snowfall, and inland freeze-thaw swings combine to stress exterior systems harder than most of inland New England.
Dover receives roughly 60 inches of snow per winter, with heavy accumulations from nor'easters driving ice dam formation on underperforming attic ventilation systems.
The Seacoast experiences roughly 140+ days per year crossing the freezing point, the single biggest driver of shingle cracking, flashing separation, and decking rot.
Proximity to the Atlantic means sustained wind exposure and salt-laden air. Our installations use 6-nail shingle fastening patterns and corrosion-resistant flashing materials standard.
