Commercial Flat Roof Installation in Spiritwood, ND | EPDM Membrane

When the roof on a commercial building in Spiritwood, North Dakota, began showing significant signs of wear, Perry, the property contact, knew it was time to find a long-term solution. After years of battling harsh North Dakota weather, the aging flat roof had reached the point where repairs were no longer practical. Perry reached out to the trusted team at Vita Roofing for a professional assessment. Following a detailed inspection, the recommendation was a full EPDM roof replacement designed to provide reliable protection and improved insulation. The project began with a complete tear-off of the existing roofing system, with crews carefully removing the old materials and loading them into 20-yard dumpsters to keep the worksite organized and efficient.

With the roof deck exposed and inspected, the installation of the new roofing system began. The team installed a tapered Poly ISO insulation system designed to achieve an R-35 rating, helping improve both drainage and energy efficiency. Low-rise foam adhesive secured the insulation boards, while screws and plates provided additional mechanical fastening. Once the insulation was in place, the EPDM membrane was rolled out and fully adhered using bonding adhesive to create a smooth, watertight surface. Flashings and primer were applied to key areas, and the parapet walls were fully adhered to ensure continuous waterproofing. The finishing touches included cap metal with a ¼-inch taper and 1-inch fill reaching X+10 on the main roof section, completing a long-lasting flat roofing system built to withstand the extreme conditions common in North Dakota.
