What We Do | Gwinner Roofing & Maintenance Roofing Services
Gwinner Roofing & Maintenance handles every roofing job from a single-shingle repair to a full commercial re-roof. Here's what we do in Gwinner.
Roof Replacement
Your roof replacement includes a full-system install: ice and water shield at eaves, valleys, and penetrations; synthetic underlayment across the entire deck; aluminum drip edge at rake and eave; starter strip with sealant; architectural shingles with 130+ mph wind rating; and continuous ridge vent for proper attic ventilation. We also install new pipe boots and vent flashing on every penetration.

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 Gwinner 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 damage and hail damage look different and require different documentation. Our HAAG-trained inspectors know what adjusters look for: granule displacement patterns, fractures in the shingle mat, seal failures, cracked ridge caps. Proper documentation is why our claims get approved.

We handle new construction from permits through final inspection. Our Gwinner office coordinates with your builder on scheduling, material delivery, and inspection timing. Typical install time is 1-3 days depending on size and complexity.

Color options in metal roofing are virtually unlimited. Matte black, charcoal, forest green, copper penny, barn red, slate blue. We order custom colors from Sheffield Metals and McElroy Metal with 40-year fade warranties. Your house, your style.

Designer shingles like GAF Camelot II, Owens Corning Berkshire, and CertainTeed Grand Manor mimic premium materials. Slate, cedar shake, heavy wood. They cost 30-50% more than standard architectural shingles but the curb appeal is worth it for higher-end Gwinner homes. Full manufacturer warranties included.
Get a Free Quote →Flat Roofing
PVC membrane for Gwinner restaurants, commercial kitchens, and facilities with rooftop grease exhaust or chemical exposure. PVC resists oils and animal fats that destroy TPO and EPDM membranes. We install IB Roof Systems and Duro-Last PVC with factory-fabricated accessories for watertight penetration details. Built-up roofing (BUR) uses 3 or 4 plies of fiberglass felt in hot asphalt with a gravel or cap sheet surface. Oldest proven flat roof system, with 30+ year service life in North Dakota. We still install BUR when the application calls for it.

Commercial roofing in Gwinner means flat and low-slope systems: TPO, EPDM, PVC, modified bitumen, and built-up roofing. We install and repair all of them. Retail, warehouse, office, restaurant, multi-family. Our commercial crew handles buildings from 2,000 to 100,000 square feet.

We hang gutters with hidden hangers screwed into the rafter tails or fascia board every 24 inches max. No spike-and-ferrule, no exposed hardware. Proper pitch is 1/4" per 10 feet toward each downspout. Too flat and water sits. Too steep and it looks wrong.
Get a Free Quote →Roof Inspection
Roof inspections are free for Gwinner homeowners. No strings, no obligation to hire us for repairs. If your roof is fine, we say so. If it needs attention, you get an honest assessment of what's going on and what it'll cost to fix.
Get a Free Quote →Emergency Roof Repair
After we secure the tarp and stop the leak, we photograph and document everything while the damage is fresh. This documentation is critical for insurance claims. Adjusters want to see the damage before any repairs are made.
Get a Free Quote →Skylight Installation
Skylight installation includes cutting the roof opening, framing a curb with doubled 2x lumber, installing the unit with factory sealant, and weaving the step flashing into the surrounding shingle courses. Interior work includes drywall framing and trim. We handle the full job in Gwinner. Outside and inside.
