Professional Gilsum Roof Installation & Repair

Owens Corning Duration shingles with SureNail technology rated to ASTM D3462 and D7158 Class H wind resistance. Our Gilsum crews install TruDefinition Duration in a full Owens Corning system. ProArmor synthetic underlayment, VentSure ridge vent, and Starter+ starter strip. Preferred Protection warranty included.

Missing shingles, cracked flashing, a leak over the kitchen. Whatever it is, we fix it. Our Gilsum repair crew runs 6 days a week. Most repairs take half a day.

Wind speeds over 60 mph cause shingle tab lift and seal failure. Hail over 1" diameter causes fractures through the shingle mat to the fiberglass reinforcement. Our HAAG-trained inspectors know the difference between cosmetic damage and functional damage. That distinction determines your insurance payout.

A new roof installation starts with getting the specs right. Roof pitch determines your material options. Attic space determines ventilation needs. Local code determines underlayment requirements. We handle all of that before the first shingle goes on.

Metal roofing costs more upfront at $12-$22 per sq ft installed in Gilsum compared to $4-$8 for shingles. But it lasts 2-3x longer and your energy bills drop 15-25%. Math works out over time.

Your shingle choice determines your warranty, your curb appeal, and how your roof handles New Hampshire weather. We'll show you samples, explain the differences, and let you pick what fits your budget. No pressure.

PVC roofing membrane for Gilsum restaurants, commercial kitchens, and any rooftop near grease exhaust. PVC resists animal fats and chemical exposure that destroys TPO and EPDM. We install IB Roof Systems and Duro-Last PVC with heat-welded seams and custom-fabricated accessories. Built-up roofing (BUR) with 3-4 plies of fiberglass felt in hot asphalt is still the longest-proven flat roof system with a 30+ year track record in New Hampshire.

Commercial roofing in Gilsum means dealing with rooftop HVAC units, drains, parapet walls, and penetrations. We work around your equipment and schedule repairs or installs to minimize business disruption.

Gutters aren't glamorous, but they're protecting your foundation, your fascia, and your landscaping. We install seamless aluminum gutters custom-formed on-site from a roll of coil stock. No seams means no leaks.

Infrared moisture scanning available for Gilsum commercial and flat roof inspections. Thermal imaging locates trapped moisture in the insulation layer without cutting core samples. We use Flir E8 cameras to map wet areas, then core sample only the suspect zones to confirm. Saves time, reduces disruption, and gives you a precise repair scope instead of a guess.

Fallen tree limb damage requires structural assessment before repair. We check rafter integrity, decking condition, and whether the ceiling joists below were impacted. If structural members are cracked or displaced, you need a framing carpenter before we re-roof. We coordinate with trusted Gilsum contractors for structural work. Insurance carriers require separate line items for structural vs. roofing repairs. We document both.

Skylight replacement is often better than repair on units over 15 years old. VELUX FCM curb-mount replacement skylights install on the existing curb frame. No structural modification needed. Low-E laminated glass with argon fill for energy efficiency. Solar-powered blinds available for light control. VELUX No Leak guarantee when installed with the complete flashing system. Your Gilsum home gets more light, better insulation, and a proper warranty.
