Flat roof repair addresses the specific problems low-slope and flat roofs face – ponding water, membrane seams that separate, and punctures or wear that lead to leaks. Flat roofs work differently than pitched roofs, so the repair approach and materials are different too.
We handle this for San Francisco, CA property owners noticing ceiling stains, visible ponding water that doesn't drain within 48 hours, or membrane that's cracked, blistered, or lifting at the seams. Flat roofs need more frequent attention than pitched roofs since they don't shed water the same way.
We inspect the membrane fully, checking seams, flashing at edges and penetrations, and drainage points for anything blocking proper water flow. Depending on what we find, repair might mean resealing a seam, patching a puncture, or addressing a drainage issue that's causing water to pool where it shouldn't. We match repair materials to your existing membrane type – EPDM, TPO, or modified bitumen – since mixing incompatible materials causes more problems down the line.
Cost depends on the extent of the damage, the membrane type, and whether drainage issues need addressing alongside the repair.
If your San Francisco, CA flat roof has a leak or ponding issue, call (213) 671-0993 for a free inspection.
