TPO Roof Repair

What This Service Involves

TPO single-ply membranes are widely used on Washington commercial buildings and modern additions because the white surface reflects heat and the seams weld into a continuous sheet. Over time seams can separate, punctures appear from foot traffic, and penetration boots crack under UV and weather. We repair TPO the right way, with hot-air welding that fuses new membrane to old rather than taping or gluing patches that peel in our wet climate. Proper welds restore a monolithic surface that keeps rain out of the deck and insulation below.

Benefits

Restores fully welded seams instead of peel-prone patches; Matches membrane thickness and color for clean repairs; Reseals penetrations that crack under UV exposure; Protects insulation and deck from trapped moisture; Maintains the reflective surface that keeps buildings cool

Our Process

1) Inspect seams, field, and penetrations for welds and punctures; 2) Clean and prep the membrane surface for welding; 3) Hot-air weld new TPO over failures and reflash penetrations; 4) Probe-test every weld and confirm a watertight seal

What Affects the Cost

Thickness and age of the existing TPO membrane; Number and length of seams needing rewelding; Condition of penetration boots and curb flashings; Whether wet insulation must be replaced first; Roof access and layout on commercial buildings

Best Time of Year

Warm, dry days help welds set cleanly, so late spring through early fall is ideal for non-emergency TPO work.
