Local Stephan Roof Installation & Repair. GAF Certified

Replacing your roof isn't just about shingles. We install ice and water shield in the valleys and along eaves, synthetic underlayment across the whole deck, new drip edge on rake and eave, starter strip, and ridge vent. That's how a roof lasts 30 years in South Dakota.

Missing shingles, cracked flashing, a leak over the kitchen. Whatever it is, we fix it. Our Stephan 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.

New construction roof installation following IRC Section R905 and local Stephan building code amendments. We calculate ventilation per IRC R806 (1:150 ratio reduced to 1:300 when 50% is within 3ft of ridge. Synthetic underlayment per ASTM D226, ice barrier per ASTM D1970 at eaves in freeze-thaw climate zones. Manufacturer-certified installation locks in the full system warranty.

We do metal roof repairs too. Loose panels, failed sealant at transitions, rust spots on older galvanized. Not every metal issue needs a full replacement. Our Stephan crew can usually fix it same-day.

Owens Corning Duration STORM shingles with triple-layer SureNail reinforcement strip. Rated to 130 mph wind per ASTM D7158. Algae-resistant granules prevent black streaking in humid South Dakota climates. We install Duration in the full Owens Corning system for Preferred Protection or Platinum Protection warranty coverage. CertainTeed Landmark PRO with NailTrak technology is our alternative pick for Stephan homeowners who want the max warranty tier.

Modified bitumen is our go-to for residential flat roofs in Stephan. Two-ply torch-applied system with a granulated cap sheet. It handles foot traffic, thermal cycling, and South Dakota UV better than single-ply at the residential scale.

Flat roofs on commercial buildings are a different animal. We install and repair TPO, EPDM, modified bitumen, and built-up systems. Our Stephan commercial crew handles retail, warehouse, office, and multi-family buildings.

We install 5" and 6" seamless aluminum gutters in Stephan. Standard homes get 5", high-volume areas and steeper pitches get 6". Downspouts every 30-40 ft of gutter run with splash blocks or underground drains.

Annual roof inspections catch small problems before they become expensive ones. A cracked pipe boot is a $150 fix. Ignoring it means $3,000 in ceiling and wall water damage. We recommend an inspection every 2-3 years for roofs under 10 years old, and annually after that.

Storm damage, fallen trees, sudden leaks. We handle all roofing emergencies in Stephan. First we stop the water, then we fix the cause. Emergency response available 7 days a week.

We install, replace, and repair skylights in Stephan homes. Fogged glass, cracked frames, persistent leaks around old skylights. We fix it all. Sometimes replacing a 20-year-old skylight is cheaper than trying to repair it.
