TPO Roofing Los Angeles

White, Welded, Watertight. Built for Flat Roofs in the Heat.

TPO roofing in Los Angeles is the system we put on most flat and low-slope buildings: a single-ply white membrane, mechanically fastened or fully adhered over the deck, with every seam hot-air welded into one continuous sheet. No tar kettle, no gravel, no laps relying on adhesive to stay shut.

Los Angeles Commercial Roofing & Roof Repair installs and repairs TPO from our yard on La Brea Ave — warehouses, strip centers, apartment buildings, churches and houses with flat sections. Every roof goes on with manufacturer-spec detailing so the 20-year warranty actually holds.

Why TPO Suits Los Angeles Buildings

Los Angeles bakes. The town sits in a bowl at the foot of the Verdugo and San Gabriel Mountains, summer runs hotter than the coast, and the sun works on a flat roof every day of the year. A white TPO membrane reflects most of that heat instead of holding it, which keeps the space below cooler and takes load off the air conditioning.

How a TPO Roof Goes On

1. Tear-off or prep

   We pull the old roof, or on a sound substrate we go over it with a cover board instead.

2. Deck and insulation

   Any soft decking gets replaced, then polyiso goes down where the building wants the R-value.

3. Membrane layout

   Sheets are rolled, relaxed and set out so the seams run the right way for drainage.

4. Hot-air welded seams

   Every lap is welded and probed. A welded seam is as strong as the sheet itself — that is the whole point of TPO.

5. Flashings and details

   Curbs, drains, pipes, parapets and edge metal, all detailed to the manufacturer's spec so the warranty stands.

TPO vs the Other Flat Roof Options

• Against torch-down. No open flame on the building, lighter weight, and a white surface instead of black cap sheet that cooks all afternoon.
• Against EPDM. Same single-ply idea, but TPO welds instead of gluing its seams and reflects heat rather than absorbing it.
• Against a coating. A coating renews a roof you already have. TPO replaces it, and it comes with a manufacturer warranty.
• Against built-up. One continuous membrane instead of layers of felt and asphalt, and no gravel to shovel when a leak needs finding.

Straight talk: TPO needs drainage. If a roof holds water because it has no slope and the drains sit high, the honest fix is tapered insulation or a silicone coating system, not a membrane sitting in a pond. We will tell you which one your roof needs after we measure it.

What Goes Into a TPO Roof

The membrane gets the attention, but the details are what keep the water out:

• 

  The Membrane

  Single-ply, reflective and UV stable, in the thickness the building and warranty call for.

• 

  Heat-Welded Seams

  Hot air fuses sheet to sheet, so the laps are not a weak point waiting to open.

• 

  Flashings

  Pipes, curbs, drains and parapets — where nearly every flat roof leak actually starts.

• 

  Insulation & Cover Board

  R-value under the sheet, and a hard board so foot traffic and hail do not dent the system.

Warranty and How Long It Lasts

A properly installed TPO roof runs twenty years and up, and the manufacturer warranty of up to 20 years is written against the system — membrane, insulation, fasteners and detailing together. That is why we do not mix parts between systems or skip the specified edge metal: a cheaper detail voids the paper that makes the roof worth buying.

Repairs, Leaks and Maintenance

A TPO roof is easy to live with. Punctures and bad welds are repaired by welding in a new patch, so the fix becomes part of the sheet instead of a bandage. Two things keep one going: clear the drains before the rainy season, and have the flashings and seams looked at once a year. We handle both, on roofs we installed and on roofs we did not.

Serving Los Angeles and the Foothills

We install TPO throughout Los Angeles, Tujunga, Shadow Hills, Lake View Terrace, La Crescenta, Sylmar and the rest of the northeast San Fernando Valley, commercial and residential. Flat roof work is dry-weather work, so the calendar tightens once the rain starts — call early.
