PVC Roof Repair

What This Service Involves

PVC membranes are chosen for Washington restaurants and buildings with grease or chemical exposure because the material resists what would degrade other roofs. Like TPO, PVC seams are heat-welded, and failures typically show up at aged welds, penetrations, or spots where plasticizers have migrated and the sheet stiffens. We weld new PVC to sound membrane using compatible material, since patching brittle PVC with the wrong product simply invites the next leak. Restoring true welded seams keeps kitchens, mechanical rooms, and interiors dry through the wet season.

Benefits

Restores heat-welded seams for a monolithic surface; Uses PVC-compatible membrane to avoid brittle failures; Reseals penetrations exposed to grease and chemicals; Protects interiors below from persistent winter moisture; Extends membrane life without a full roof replacement

Our Process

1) Evaluate welds, penetrations, and areas of membrane stiffening; 2) Clean and prep the PVC surface for hot-air welding; 3) Weld matched PVC over failures and reflash penetrations; 4) Probe-test welds and verify a continuous watertight seal

What Affects the Cost

Age of the PVC and degree of plasticizer loss; Membrane thickness and matching stock availability; Number of penetrations and grease-exposed details; Whether stiffened sections must be cut out and replaced; Building type and rooftop equipment around the repair

Best Time of Year

Warm, dry weather produces the cleanest welds, so we schedule planned PVC repairs from late spring into early fall.
