Flat roof leak repair means tracing a leak on a low-slope roof back to its actual source – which on a flat roof can be a seam failure, a puncture, or a drainage problem causing water to pool where the membrane is weakest, not always where the leak shows up inside.
We handle these calls throughout San Dimas, CA for both commercial and residential flat roofs, often after noticing a ceiling stain, active dripping during rain, or visible standing water that isn't draining. Flat roof leaks can be trickier to pinpoint than pitched roof leaks since water can travel along the membrane before finding a way in.
We inspect the membrane surface for seam separation, punctures, or blistering, and check drainage points to see if ponding water is contributing to the problem. Once we find the actual entry point, we repair it properly – resealing seams, patching punctures, or addressing a drainage issue – rather than just sealing the spot where water shows up inside, since that approach rarely holds on a flat roof.
Cost depends on how accessible the leak source is and whether drainage issues need correcting alongside the leak repair.
If your San Dimas, CA flat roof is leaking, call (213) 671-0993 for a free inspection and we'll find the real source.
