PVC Roofing

What This Service Involves

PVC is our go-to single-ply where a roof faces restaurant grease exhaust, industrial runoff, or the persistent standing water that shows up on older Northwest flat decks. The welded seams are exceptionally strong, and the membrane's chemical resistance keeps it from degrading where lesser roofs break down. We build in tapered insulation to move water off the field, but PVC's inherent resistance to ponding gives it an extra margin on stubbornly flat sections. Reinforced with a polyester scrim, the sheet holds up to foot traffic from HVAC servicing and the constant wetting our climate delivers.

Benefits

Welded seams deliver outstanding strength and leak resistance; Chemical and grease resistance suits restaurants and industrial sites; Superior ponding-water tolerance for stubbornly flat decks; Reflective white surface cuts cooling loads in summer; Scrim reinforcement withstands rooftop foot traffic

Our Process

1) Remove the old roof and inspect the deck for damage; 2) Install cover board and tapered insulation for drainage; 3) Fasten or adhere the PVC membrane across the field; 4) Hot-air weld seams and details, then probe every joint for integrity

What Affects the Cost

Membrane thickness and reinforcement grade specified; Total area and the density of rooftop equipment to flash; Whether grease or chemical exposure requires upgraded detailing; Attachment method suited to wind exposure and deck type; Removal and disposal of the existing roof assembly

Best Time of Year

Summer's dry stretch lets PVC welds and adhesives cure properly, so we target June through September for these installations.
