New flat roofs built to handle LA sun and winter rain. LionRidge Roofing installs TPO, torch down, and modified bitumen roofing on homes and commercial buildings across Los Angeles County.
Get expert advice on the right flat roof system for your property.
Flat and low-slope roofs are everywhere in Los Angeles, from the flat sections behind parapets on Spanish-style homes to garages, apartment buildings, and commercial properties. They need a different kind of roofing than a sloped house. We install the systems that hold up best here: reflective TPO membranes, torch down roofing, and multi-layer modified bitumen. Every job starts with getting the slope and drainage right, because standing water is one of the biggest causes of flat roof failure.
From repairs to full replacements, we handle every kind of flat roof work.

TPO and torch down are two of the most common flat roof systems in Los Angeles, and both perform well when they’re installed right. TPO is a white single-ply membrane that reflects the sun and helps keep the rooms under the roof cooler. Torch down is a multi-layer modified bitumen system that’s extremely tough and handles foot traffic well. We look at your roof’s size, slope, drainage, and how it’s used, then recommend the system that fits.

Answers to common questions about TPO, torch down, and modified bitumen flat roofs.
It depends on the roof. TPO is a great fit for most homes and buildings where you want a reflective, energy-efficient surface. Torch down is a strong choice for roofs that get foot traffic or need extra toughness, and it’s very common on residential flat roofs in LA. We look at your roof’s size, slope, drainage, and use, then recommend what fits your property and budget.
TPO (thermoplastic polyolefin) is a single-ply roofing membrane, usually white, with seams that are heat-welded together. The white surface reflects sunlight, which helps keep the space under the roof cooler. It’s one of the most popular flat roof systems for both homes and commercial buildings.
Torch down is a type of modified bitumen roofing. Rolls of asphalt-based membrane reinforced with polymers are heated with a torch so they bond to the roof and to each other, creating a tough, multi-layer waterproof surface. It’s durable, walkable, and widely used on flat roofs across Southern California.
Modified bitumen is an asphalt-based roofing membrane reinforced with polymers for strength and flexibility, installed in multiple layers. Torch down is one way of installing it. It holds up well to foot traffic, which makes it a good choice for roofs with HVAC equipment or regular access.
Both are solid choices when they’re installed correctly. TPO’s main advantage is its reflective white surface, which keeps the roof cooler and can help meet California’s cool-roof energy requirements where they apply. Torch down’s main advantage is toughness: its multiple layers resist punctures and foot traffic. Your roof’s layout, drainage, and how you use it usually decide which is the better fit.
With proper installation and drainage, TPO roofs commonly last 20 years or more, and torch down roofs typically last 15 to 20 years or more. Regular inspections and fixing small problems early help any flat roof reach the long end of its life.
It depends on the size of the roof, the system you choose, whether the old roof has to be torn off, the condition of the deck underneath, and how many vents, drains, and skylights need to be worked around. We’ll give you a free, detailed written estimate so you know exactly what you’re paying for.
Sometimes. If there’s only one existing layer and the roof and deck underneath are dry and sound, installing over it can save on tear-off costs. If there’s trapped moisture, more than one layer, or damage, a full tear-off is the right call. We check before recommending either, and we’ll tell you honestly which makes sense.
Both. We install TPO, torch down, and modified bitumen roofs on homes, including the flat sections common on Spanish-style houses, as well as on garages, apartment buildings, and commercial properties throughout LA County.
Ponding usually comes from a roof without enough slope, low spots in the deck, or drains and scuppers that are blocked or poorly placed. Standing water wears roofing out faster and can lead to leaks. When we install a new flat roof, we correct slope and drainage problems so water moves off the roof.
Yes. TPO seams and patches are heat-welded, and torch down and modified bitumen are repaired with compatible materials. Many flat roof leaks come from a single spot, like a failed seam, flashing, or drain, and can be fixed without replacing the whole roof. See our Flat Roof Repair page for more.
Every new flat roof we install comes with our 10-year workmanship guarantee, plus the manufacturer’s warranty on the roofing materials.
