Flat Roof Repair Built for Mission Hills
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.

Why Mission Hills Homeowners Choose Us
With coastal-inland transition with marine layer influence, cutting corners on flat roof repair fails fast. 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.
Warranty & Materials
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.

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. All warranty documentation is registered in your name at project completion.
How does salt air in Mission Hills affect flat roof repair?
Coastal Mission Hills homes face accelerated corrosion on standard fasteners and flashing. For every flat roof repair project near the coast we specify stainless steel or copper fasteners, marine-grade underlayments, and Kynar-coated or aluminum components rated for salt exposure — details typical roofers skip.
How much does flat roof repair cost in San Diego?
Localized seam or flashing repairs typically run $600–$2,500. Larger sectional repairs and blister cut-outs run $2,500–$8,000. A full silicone coating system is usually priced per square foot and quoted after we confirm the substrate is dry and sound.
Why does water pond on my flat roof?
Either the roof was built without adequate slope, the insulation has compressed, the structure has deflected, or the drains and scuppers are undersized or blocked. Coating over ponding does not fix it — tapered insulation or additional drainage does.
Is a flat roof coating worth it?
Yes, when the membrane below is intact and dry. A silicone or acrylic system at proper mil thickness seals seams, reflects heat, and adds 10–20 warrantied years for far less than a tear-off. Over saturated insulation, a coating traps moisture and fails.
Can you repair TPO seams, or does the whole roof need replacing?
TPO seams are heat-welded and fully repairable. We weld a patch over the failed area and probe-test it. Replacement is only warranted when the membrane has lost thickness across the field or the insulation below is saturated.
How long does a flat roof repair take?
Most repairs are completed in one day. Coating systems take 2–4 days including prep, primer where required, and two-coat application. Tapered insulation and drainage corrections take longer and depend on materials.
Do you repair flat roofs on commercial and HOA buildings?
Yes. We work with property managers and HOA boards across San Diego County, provide line-item scopes suitable for board approval, and schedule work around tenant operations.
