Trusted Spearfish Roofing Experts

We handle the whole replacement from permits to final inspection. Our Spearfish office pulls the permit, coordinates the dumpster, runs the crew, and schedules the building inspector. You sign the contract and we handle the rest.

Roof repairs get worse when you ignore them. A $400 flashing repair turns into $4,000 of water damage inside the wall. Our Spearfish crew can usually get there within 48 hours for non-emergency repairs.

We work with every major insurance carrier. State Farm, Allstate, USAA, Liberty Mutual, Farmers, Nationwide. Our supplement team knows Xactimate line items and fights for full replacement when your roof qualifies.

A new roof installation starts with getting the specs right. Roof pitch determines your material options. Attic space determines ventilation needs. Local code determines underlayment requirements. We handle all of that before the first shingle goes on.

Metal roofing in South Dakota makes sense. It reflects heat, handles high winds, and sheds hail better than shingles. We install standing seam, corrugated, and metal shingle panels.

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 Spearfish homeowners who want the max warranty tier.

TPO single-ply membrane in 60-mil or 80-mil thickness, hot-air welded seams, fully adhered or mechanically attached over polyiso insulation board. We install per NRCA and manufacturer specifications. Ponding water is the number one cause of flat roof failure. We use tapered ISO insulation to create minimum 1/4" per foot slope to drains. FM 4473 rated systems available for hail-prone Spearfish areas.

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

Improperly sized gutters cause fascia board rot and foundation erosion. We calculate gutter capacity using the rainfall intensity formula: roof square footage x pitch factor x rainfall rate (inches/hr for Spearfish). Standard 5" K-style handles 5,520 sq ft of effective roof area. Bigger roofs or steeper pitches need 6" gutters with 3x4" downspouts. We hang with hidden hangers screwed into rafter tails every 24".

Infrared moisture scanning available for Spearfish commercial and flat roof inspections. Thermal imaging locates trapped moisture in the insulation layer without cutting core samples. We use Flir E8 cameras to map wet areas, then core sample only the suspect zones to confirm. Saves time, reduces disruption, and gives you a precise repair scope instead of a guess.

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

Vented skylights open to let hot air escape. Great for kitchens and bathrooms in Spearfish. Fixed skylights are cheaper and simpler. Solar-powered options from VELUX qualify for the federal 30% tax credit through 2032.
