Flat Roof & Low-Slope Roof Repair in San Diego

Low-slope roofs fail at transitions, not in the field. The leak is almost always a seam that has lost its weld, a pitch pocket that has dried out, an HVAC curb flashing that was never terminated properly, or a drain that no longer drains — leaving standing water to work its way through the weakest lap. Signs you need flat roof repair include interior stains near walls and mechanical units, visible ponding 48 hours after rain, blisters or ridging in the membrane, and gravel or granule loss exposing the felt. Material choices matter: single-ply repairs are welded, torch-down repairs are torched and mastic-detailed, and a coating only performs when the substrate underneath is sound and dry. We tell you which category your roof is in before quoting.

Commercial and multifamily buildings, mid-century residential low-slope roofs, additions and patio covers, and any roof where water stands after rain.

We survey the roof plane, probe every accessible seam, moisture-scan or core-cut where saturated insulation is suspected, and photograph each failure. You receive a fixed-price scope that separates repair from re-cover honestly. Repairs are welded or torched to manufacturer spec, drainage is corrected with tapered insulation or new drains, and coating systems are applied only over prepared, dry substrate at specified mil thickness.

Membrane repairs carry our written workmanship warranty. Coating systems carry manufacturer warranties of 10–20 years depending on mil thickness, and full re-cover systems in TPO or PVC carry manufacturer warranties up to 30 years.
