Bellevue PVC Roof Project | 50 Mil PVC by IB Roof Systems
Pinnacle Roofing Professionals, LLC completed this Bellevue PVC roof project in Bellevue, Washington. The existing flat roof was a failing torchdown system that had developed leaks and seam failures. Rather than applying another layer of temporary repairs, we performed a full tear-off and installed a new 50 mil PVC membrane by IB Roof Systems in gray, giving the building a long-lasting, low-maintenance flat roof.
Why Torchdown Roofs Fail in Bellevue
Torchdown (modified bitumen) roofing systems can be vulnerable in the Pacific Northwest climate. Over time, repeated expansion and contraction, UV exposure, and ponding water can cause seams to open and leaks to develop. In this case, improper ventilation had also contributed to moisture damage and deterioration of the plywood decking, making a patch-and-repair approach a poor investment.
Full Tear-Off, Deck Replacement, and Ventilation Correction
We started by removing the old torchdown roof and all compromised plywood. Improper ventilation had damaged the decking, so every sheet was replaced with sound material. We also installed new fascia to restore a clean, finished edge at the perimeter. Correcting ventilation and replacing the deck gave the new PVC roof a solid, dry foundation and helped prevent the same problems from recurring.
50 Mil PVC Membrane by IB Roof Systems
The new roof was finished with a 50 mil PVC single-ply membrane by IB Roof Systems in gray. PVC roofing is heat-welded at the seams, creating a monolithic, watertight surface that resists UV rays, chemicals, and standing water. Unlike torchdown systems that rely on adhesives and torched seams, PVC seams are fused together for stronger, longer-lasting performance. The 50 mil thickness is a dependable choice for commercial and residential flat roofs in Bellevue’s wet climate.
