Low-slope roofs

Flat Roof Repair in Los Angeles, CA

LA Roof Repair Pros provides flat roof repair in Los Angeles, CA, on the low-slope roofs of homes, additions, garages, apartment buildings and commercial properties. Flat roofs fail differently from pitched ones: water sits instead of running off, so seams open, blisters form, drains clog and the areas that pond wear through first. The roofer finds the failures, repairs them with materials compatible with the existing membrane, corrects the drainage where he can, and tells you when the roof has reached the point where replacement beats patching.

How flat roof repair works in Los Angeles

The inspection walks the whole roof, because flat roof leaks travel along the deck and show up inside far from the entry point. The roofer checks the seams and laps, the flashings at walls, curbs and penetrations, the drains and scuppers, the ponding areas that hold water after rain, and blisters and cracks in the surface. The membrane type, torch-down or modified bitumen, TPO or PVC, built-up or a coating, decides the repair materials.

Repairs use the same or a compatible material, heat-welded or torched where the membrane calls for it, with new flashing at failed details. Clogged drains are cleared and low areas that pond are built up or given drainage where practical. Where the seams have opened across the roof or the membrane has gone brittle, the estimate is for a new membrane, and the photos show why.

Coatings, patches and what actually lasts

Roof coatings extend the life of a sound flat roof and do nothing for one that is failing underneath. Patches with incompatible materials, mastic over TPO for example, fail quickly. The estimate names the membrane and the repair material so you can see they match.

For commercial buildings, a maintenance visit each year to clear drains and reseal details is the cheapest roofing money there is.

    Building up low areas or adding drainage is quoted as its own work.

  • Replacement area

    When the membrane is done, the new membrane is priced by the square.

Flat and low-slope roof repair questions from Los Angeles homeowners

Ask us directly

Why does my flat roof leak in the same spot every year?

Usually because water ponds there and works at the seam or the surface until it opens. The repair addresses the drainage as well as the seam, or the spot fails again.

Is a coating a repair?

A coating protects a roof that is still sound. It does not fix open seams, failed flashings or a wet insulation layer. The inspection says which you have.

How long does a flat roof last?

It varies widely by membrane and installation, from 10 to 30 years. Drains kept clear and details resealed every few years make the difference.

Do you do commercial flat roofs?

Yes: offices, retail, warehouses and apartment buildings, repairs and full membrane replacement, with maintenance visits by arrangement.
