Most Portola Valley flat roof issues combine two or three of these elements, which is why a full inspection matters.
TPO seam separation gets properly heat-welded, not just caulked over as a temporary fix.
We identify the membrane type first, since EPDM and TPO repairs use different adhesive systems.
We identify why water is pooling — often a low spot or blocked drain — before recommending a solution.
Modified bitumen blisters and seam issues are repaired using proper torch-down or cold-adhesive technique depending on the situation.
We clear and repair drains and scuppers as part of a full Flat Roof Repair visit.
Rooftop HVAC units and their curbs are a frequent source of Portola Valley commercial roof leaks that general roofers often overlook.
