Our Services
Full-service roofing contractor in Gann Valley — from asphalt shingle roof replacement and emergency hail damage repair to metal roofing, flat roof systems, and gutter installation. Every project is installed by manufacturer-certified crews with workmanship warranties.
Trusted by homeowners and businesses across Gann Valley.
A new roof is a big expense. We offer 12-month same-as-cash and low-interest financing through GreenSky and Hearth. Get your roof done now, pay over time.
Fully licensed, bonded, and insured in South Dakota. We carry $2M in general liability. Workers' comp on every crew member. Your property is protected if anything goes sideways.
We run magnetic nail sweeps three times. Once during tear-off, once after install, once before we leave. Tarps on the ground, dump trailer in the driveway. Your yard looks the same when we're done.
Only 3% of roofers earn this certification. It means we can offer the Golden Pledge warranty: 25-year workmanship plus 50-year materials. Best warranty in roofing, full stop.
Simple Process
We climb up, walk the entire roof, and document what we find with photos and measurements. Takes about 30 minutes. You'll see exactly what we see.
We price by the roofing square with all materials itemized. You'll see exactly what you're getting. Shingle brand, underlayment type, ventilation specs, flashing details.
No subcontractors. Our crews, our equipment, our supervision. A project manager checks in throughout the day and does a final quality inspection before cleanup.
We walk the property with you, show you the finished roof, answer any questions. Then we run the magnetic nail sweep and clean up every scrap of debris.
Verified Reviews
"My neighbor used Gann Valley Roofing & Maintenance and recommended them. Glad I listened. Fair price, professional crew, no drama. They even fixed a piece of siding that got dinged during tear-off without me asking."
"Asked for a second opinion because another company said I needed a full replacement. Gann Valley Roofing & Maintenance said I only needed valley flashing repair and some shingle replacement. Saved me about $14,000. I trust these guys."
"Storm chasers were going door to door after the hailstorm. Called Gann Valley Roofing & Maintenance instead because they're actually from Gann Valley. Got a fair deal and a warranty that means something."
