Roof replacement, siding installation, replacement windows, and seamless gutters for Portland and Greater Casco Bay homeowners. Transparent pricing. Satellite-measured estimate in under 2 minutes, no sales visit required.
Portland's housing stock is one of the most varied in New England, 19th-century Victorians on the West End and Munjoy Hill, post-war capes through Deering and Stroudwater, and contemporary builds out toward Falmouth and Cape Elizabeth. Each style demands a different roof-system approach: complex valleys and dormers on the older homes, exposed eaves on the seacoast houses, and steep pitches in the historic districts.
Nova installs engineered exterior systems specifically calibrated for the Greater Portland climate. Our standard roof build pairs 130-mph-rated architectural shingles with ice and water shield extending 3–6 feet from the eaves, the freeze-thaw cycling along Casco Bay routinely overwhelms code-minimum installations. For homeowners replacing siding, our vinyl systems include house wrap and insulation board built to handle the salt-air exposure on the Portland peninsula and surrounding shoreline.
We serve homeowners across the Portland peninsula and surrounding communities:
Portland homes endure a severe mix of Nor'easter wind gusts ripping off Casco Bay and heavy accumulations of dense, wet snow. A basic builder-grade roof simply cannot survive these repeated seasonal extremes.
At Nova, our engineered roofing systems are specifically formulated for the Southern Maine coast. First, we install high-wind resilient architectural shingles secured with enhanced 6-nail nailing schedules (rated for 130 mph). Second, our strict "Ice and Water Barrier" requirements vastly exceed standard local code, preventing the frequent and destructive ice dams synonymous with Portland winters.
As elite factory-certified installers, we provide our Portland clients with comprehensive non-prorated system protection.
