Roofing, Gutters & More in Onslow

Our service list isn't complicated: we fix roofs, replace roofs, and install new ones. We also handle gutters, metal systems, and flat roofing for commercial buildings across Onslow.

Roof Replacement

GAF Timberline HDZ with the full GAF Roof System qualifies your home for the Golden Pledge warranty. That's 25 years on workmanship and 50 years on materials, including algae protection. We install Cobra Snow Country ridge vent with external baffle, FeltBuster synthetic underlayment meeting ASTM D226 Type II equivalent, and Starter Match Pro starter strip. Every component is GAF-approved and inspection-documented.

roof repair

Roof Repair

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 Onslow 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.

storm damage repair

Storm Damage Repair

Not all storm damage qualifies for a full replacement. Hail might only damage one slope. Wind might only lift shingles on the windward side. We document exactly what's damaged and let the insurance company make the call. Honest documentation gets claims approved. Inflated claims get denied.

metal roofing

Metal Roofing

Metal roof repairs are usually sealant failures at transitions, loose panels from improper installation, or rust spots on older galvanized systems. Our Onslow crew repairs all metal types. Not every issue needs a full replacement. Sometimes a sealant touch-up or panel re-securing solves it.

shingle roofing

Shingle Roofing

Architectural shingles are what we install on 90% of Onslow 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.

flat roofing

Flat Roofing

The number one cause of flat roof failure is ponding water. Standing water that doesn't drain within 48 hours after rain. We solve ponding by installing tapered insulation systems that create positive slope to drains, scuppers, or roof edges. Minimum 1/4" per foot of slope eliminates standing water.

gutter installation

Gutter Installation

Gutter sizing matters more than most homeowners realize. We calculate the effective roof area, local rainfall intensity, and the number of downspout outlets needed to handle peak flow. Undersized gutters overflow. Undersized downspouts back up. We size everything to handle Onslow's worst rain.

skylight installation

Skylight Installation

Skylights done right bring natural light into spaces that need it most. Bathrooms, hallways, closets, kitchens with limited windows. We install VELUX and Fakro units with manufacturer flashing kits that integrate with your existing shingle field. Proper flashing is everything. Bad skylight installs are a leading cause of roof leaks.
