Complete Roofing Solutions for Gilsum
Gilsum Roofing & Maintenance offers a complete range of roofing services in Gilsum and Nashua, Peterborough, South Sutton, West Chesterfield, Barnstead. Every job gets the same attention. Big or small.
Roof Replacement
Full roof replacement starts with a complete tear-off down to the deck. We inspect every board for rot or soft spots. In Gilsum, we find decking damage on about 30% of tear-offs. Damaged sections get replaced with CDX plywood before anything else goes on. Then we build up: ice and water shield in valleys and at eaves, synthetic underlayment across the full deck, new drip edge on every edge, starter strip, field shingles, hip and ridge caps, and ridge vent. Dumpster, permits, and cleanup included.

Improper step flashing is the leading cause of roof leaks at wall-to-roof transitions. Step flashing needs to be woven between shingle courses with each piece extending 4" above the shingle exposure. We see Gilsum homes where the last roofer used continuous L-flashing or just caulked the gap. That always fails. We tear it out and install proper step flashing with a kick-out diverter at the bottom per IRC R905.2.8.3.

Wind speeds above 60 mph cause shingle tab lift and adhesive seal failure per ASTM D7158 testing protocols. Our Gilsum inspectors check the entire windward exposure. Not just the obvious damage. Poor ventilation causes ice dams which cause water intrusion under the shingle field during freeze-thaw cycles. We document all contributing factors so your insurance claim covers root-cause repairs, not just surface patches.

Proper ventilation is the most overlooked element in new roof installation. We calculate intake and exhaust per IRC R806 based on attic square footage. Balanced ventilation. Soffit intake matched to ridge exhaust. Keeps your attic cooler in summer and drier in winter. That extends roof life and cuts your energy bill.

Standing seam metal with Kynar 500 PVDF fluoropolymer finish. The gold standard for color retention and chalk resistance. We install Sheffield Metals and McElroy Metal panels in 24-gauge Galvalume steel. UL 2218 Class 4 impact resistance (qualifies for insurance discounts in most New Hampshire markets). UL 790 Class A fire rating. Wind uplift rated to 140+ mph per ASTM E1592 testing. Concealed Z-clips allow thermal expansion without stress on fasteners. That's what makes standing seam leak-proof.

Architectural shingles are what we install on 90% of Gilsum homes. They're thicker, heavier, and more wind-resistant than the old 3-tab flat shingles. They also look dramatically better. Dimensional profiles that mimic wood shake or slate. Standard architectural shingles carry a 30-year warranty. Premium versions go to 50.

EPDM (rubber roofing) has a 50+ year track record as a flat roofing membrane. We install fully adhered EPDM with taped or glued seams over polyiso insulation. It's a great option for Gilsum building owners who want proven performance at a lower cost than TPO or PVC.

Seams hot-air welded at 900°F+ and tested with a seam probe. Fully adhered systems for wind uplift zones per FM I-90 or I-120. Mechanically attached for re-roofs over existing insulation.

Seamless aluminum in 5" K-style is the standard for Gilsum residential. We use 6" K-style on larger homes, steeper pitches, or roof areas with high water volume. Downspouts are 2x3" on 5" gutters and 3x4" on 6" gutters. Matched to handle the flow.

We don't inspect roofs from the ground with binoculars. We get on the roof. Every inspection includes a full walkthrough: shingle condition, flashing integrity, pipe boots, ridge vent, soffit ventilation, gutter function, and visible attic moisture signs. You get photos and a written report.
