This Tacoma commercial PVC roof project covers a 154,000-square-foot warehouse located just south of the Tacoma Dome, off Interstate 5. Pinnacle Roofing Professionals replaced the building’s aging exposed fastener metal roof with a 60 mil IB Roof Systems PVC membrane, adding Hunter Poly-ISO insulation board to move the dew point out of the roof assembly and eliminate condensation problems.
Project Details: Tacoma Warehouse Roof Replacement
The existing exposed fastener metal roof had reached the point where screws were backing out and panel holes were enlarging, creating leaks across the large low-slope surface. In addition, the metal roof was trapping condensation. Pinnacle Roofing designed a new assembly that used Hunter Panels Poly-ISO insulation to raise the dew point, followed by a fully adhered 60 mil IB PVC membrane with heat-welded seams for a monolithic, watertight finish.
Why Switch From Exposed Fastener Metal to PVC
Exposed fastener metal roofs can leak as fasteners loosen and washers degrade over time. PVC membrane roofing eliminates thousands of penetration points by using heat-welded seams and a continuous membrane field. For a large commercial warehouse in Tacoma’s wet climate, the PVC system provides better long-term waterproofing and can be maintained more easily than a screw-down metal roof.
