Ashland Commercial Roof Leak Repair Contractor

We mark the stain inside and measure it to a wall or column, find that spot on the roof and check every curb, pipe, seam and drain upslope. Seams get probed, flashing terminations checked, and suspect areas water tested one at a time starting downslope.

TPO and PVC leak at welds, corners, curb flashing and drain clamps. EPDM leaks at seam tape, T-joints and pipe boots. Mod bit leaks at lap edges and blisters, built-up roofs at bare gravel spots, and metal at screw washers, end laps and skylight panels. Parapets get checked on every type.

Yes. On cold mornings warm indoor air turns to water on the underside of the deck or panels and drips, often across many spots and with no rain. Shops with bare steel and buildings with wash-down areas see it most. Insulation and ventilation fix it, and a roof patch does nothing.

They cut through the roof and rely on flashing and sealant that wear out before the membrane. Unit vibration loosens curb flashing, pitch pan sealer shrinks, skylight gaskets crack and condensate lines wear the surface. A large curb with no cricket also holds water against its upslope side.

When water is coming in during rain or cold weather and the real repair needs a dry, warm surface. Roof cement and fabric over a split seam, tape over an open metal lap or a weighted tarp holds it off. Each temporary spot gets marked and dated, and the permanent repair follows when the forecast clears.

A temporary repair uses cement, tape or a tarp applied wet or cold to stop water for now. A permanent repair cleans, primes and cuts back the damaged layers, then welds or adheres matching membrane on a dry surface so it becomes part of the roof. Mastic on a TPO seam still needs a welded patch later.
