Residential & Commercial Roofing in Onaka
Onaka Roofing & Maintenance offers a complete range of roofing services in Onaka and Alexandria, Buffalo Gap, Deadwood, Garden City, Hurley. Every job gets the same attention. Big or small.
Roof Replacement
We replace roofs. It's what we do more than anything else. Our Onaka crews average 15-20 complete tear-off and replacements per month. That kind of volume means we've seen every situation: steep pitches, multiple layers, rotted decking, improper ventilation from the last guy. We fix all of it and install a roof system that's warranted for decades.

Roof Repair
Our roof repair process: inspect the issue, identify the root cause, quote the fix, do the work, warranty the repair. Simple. If the root cause is widespread (poor ventilation causes ice dams, for example), we'll recommend addressing that too. But the choice is always yours.

Storm Damage Repair
Wind speeds above 60 mph cause shingle tab lift and adhesive seal failure per ASTM D7158 testing protocols. Our Onaka inspectors check the entire windward exposure. Not just the obvious damage. Poor ventilation causes ice dams which cause water intrusion under the shingle field during freeze-thaw cycles. We document all contributing factors so your insurance claim covers root-cause repairs, not just surface patches.

New Roof Installation
Proper ventilation is the most overlooked element in new roof installation. We calculate intake and exhaust per IRC R806 based on attic square footage. Balanced ventilation. Soffit intake matched to ridge exhaust. Keeps your attic cooler in summer and drier in winter. That extends roof life and cuts your energy bill.

Shingle Roofing
Shingle color matters more than you think. Dark shingles absorb heat. Great for cold South Dakota winters, harder on cooling bills in summer. Lighter colors reflect heat. Algae-resistant granules prevent black streaking. We bring shingle samples to your Onaka home so you can see them against your siding and trim.

Flat Roofing
PVC membrane for Onaka 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 South Dakota. We still install BUR when the application calls for it.

Commercial Roofing
TPO is our most-installed commercial membrane in Onaka. 60-mil thickness, hot-air welded seams, mechanically attached or fully adhered over polyiso insulation. The weld is stronger than the membrane. 15-20 year manufacturer warranties depending on system build-up.

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.
