Roofers in Commerce, CA
Roof inspection in Commerce usually starts with one question: has the sun already done the damage, or is the winter rain about to expose it? Most homes here were built in the 1950s and 1960s, which means the original composition shingles are at the end of their useful life, and the flat commercial roofs along the rail corridors age fast under intense inland heat. We’re Koreatown Roofing, a roofing-only contractor, and we’ve served Commerce since 2014. Call (866) 974-2271 when you want a straight answer about what’s happening up there.
Why Commerce Homes Are Different
Commerce sits in the hot, dry inland Los Angeles Basin, and that shapes every roof we look at. Summers bring months of direct UV exposure with almost no rain, so flat roofs on warehouses and manufacturing buildings fail from heat aging, membrane shrinkage, and ponding water at scuppers and drains. Diesel soot from the constant truck traffic along the 710 and 5 freeways settles on commercial roofs and accelerates membrane wear in ways you won’t see in residential-only cities.
The housing stock is mostly small, single-story stucco homes from the 1950s and 1960s on tight lots. These houses carry low-pitch or shallow gable roofs, often with the original composition shingles still in place. By now those shingles are brittle, the granules are washing into gutters, and the flashing around vents and chimneys has dried out. When the short winter rainy season hits, even a small deferred repair turns into a ceiling stain. Commerce is a small, fully built-out industrial suburb, so the same contractor is often bidding a TPO re-roof on a warehouse near the rail yard and patching a 1950s shingle house a few blocks away. That mix of flat commercial work and mid-century residential repairs is what makes roofing in Commerce different from any neighboring city.
Styles & brands we work with






Our Main Commerce Services
Most Commerce property owners call us for one of two things: a roof that’s already leaking or a roof that’s too old to trust. Here’s what each involves in this city.
Roof Repair in Commerce
Repair work in Commerce splits between two very different roof types. On the residential side, we’re usually replacing cracked or missing composition shingles, resealing pipe boots, and fixing flashing that’s pulled away from stucco walls on 1950s and 1960s homes. On the commercial side, we’re patching heat-split modified-bitumen, clearing debris from scuppers, and sealing membrane seams that diesel soot and standing water have degraded. The one thing both have in common: small leaks don’t stay small once the winter rain arrives. See Roof Repair in Commerce for the full breakdown of what we fix and what it costs.

Roof Replacement in Commerce
When a Commerce roof has reached the end of its service life, replacement is a bigger decision, and the material choice matters. We work with seven manufacturers, including GAF and CertainTeed, so you’re not locked into whatever one supplier happens to have in stock. For the many flat commercial buildings in Commerce, that often means TPO or modified-bitumen systems chosen for heat reflectivity and ponding resistance. For homes, it means the right shingle rating for years of inland sun. Full details are on Roof Replacement in Commerce.

Roof Inspection in Commerce
A roof inspection in Commerce is the fastest way to know whether a 60-year-old shingle roof will survive another rainy season or whether a flat commercial roof is holding water at the drains. Homes built in the 1950s and 1960s are at the age where seams fail quietly, and the hot inland summers make that damage worse before the rain ever arrives. If you need a professional Roof Inspection, we document what we find with photos and give you a written line-item quote, not a verbal estimate you have to trust.

Do I need a roof inspection before selling a house in Commerce?
Most Commerce sellers benefit from one. A documented inspection report gives you a clear picture of what a buyer’s inspector will flag, and you can share the roof’s condition up front instead of losing a deal late. Call (866) 974-2271 to schedule yours.
How often should a Commerce roof be inspected?
Every two to three years for a shingle roof, and annually for a flat commercial roof in Commerce. The heat and ponding water here cause wear that stays hidden until a leak appears. Call (866) 974-2271 for a free estimate.

In Commerce, the biggest price drivers are roof accessibility and decking condition. Tight lots with limited staging room, plus 60-year-old decking that needs replaced once shingles come off, push costs toward the upper end. Every quote we give is a fixed, written, line-item price, so the number you approve is the number you pay.

We do. Commerce is unusual because residential and industrial roofing sit side by side, so our crews work on 1950s shingle homes and flat TPO warehouses in the same week. That’s the city, and we’re built for exactly that mix.

What Commerce Customers Say
"Full replacement after the hail. They handled the insurance adjuster meeting, documented everything, and I did not have to argue with anybody. Crew was here three days and the yard was cleaner when they left than when they started."
— Tracy Ackerman"Fixed the leak and it has stayed fixed through a wet winter. Scheduling the initial estimate took about a week and a half, so they're clearly busy."
— Steven Wong"Tile roof, three cracked tiles and a slipped one. Matched the tile, no color mismatch, and it took him half a day."
— Bryce Pruitt
