Fast, Reliable Roof Replacement Across Commerce
Roof replacement in Commerce typically costs $7,800 – $14,200 for a standard asphalt shingle reroof on a mid-century tract home, while flat roof replacement on the commercial and multi-family stock that dominates this city runs $9,500 – $18,000 depending on membrane type and decking condition. Most Commerce jobs take 2 – 4 days once materials are on-site, with flat-roof tear-offs running a day or two longer. If you’re off the I-5/710 interchange or near the Citadel Outlets and your roof is showing its age, call (866) 217-3967 and we’ll give you a straight answer on whether you need a repair, a recoat, or a full replacement.
We work throughout Commerce regularly, so we know the housing stock here: mid-century stucco tract homes with low-pitch roofs, small multi-family buildings with original built-up roofing, and the flat-roofed warehouse and shop space that defines this city’s commercial core. That means our Roof Replacement crews arrive already knowing what to expect on your street, not figuring it out from the ladder.
Why Moreno Valley Roof Repair Is Commerce’s Preferred Roof Replacement Company
Commerce presents a roofing profile that most inland contractors don’t see often: low-slope tar-and-gravel, modified-bitumen cap sheet, and single-ply membranes dominate, not the steep shingle roofs you’d find in the hills. Ruben Ibarra built Moreno Valley Roof Repair around this exact reality – a brand-agnostic shop that works with GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral, so the recommendation matches the building, the budget, and the sun load, not whichever manufacturer gives us the best rebate.
Commerce customers call us because we don’t do single-brand upsells. On a flat-roof warehouse off Bandini Boulevard, we might recommend a Boral or GAF product where a tract house near Civic Center Drive gets an Atlas or Tamko architectural shingle. The point is we install all of them and can tell you the real difference between a GAF Timberline and an Owens Corning Duration without a sales pitch attached.
Our response time to Commerce is consistent – most estimates are scheduled within 2 – 3 business days, and we show up when we say we will. We also offer standalone roof inspections, so you can get an honest assessment of what your roof actually needs before spending a dollar on repair or replacement.
Styles & brands we work with






Reroofing in Commerce
Reroofing in Commerce usually means tearing off a mid-century built-up roof or an aging shingle layer and replacing it with a system that can handle basin heat, freeway soot, and ponding water without failing early. Most reroof jobs here run $6,500 – $12,000 for residential asphalt shingles depending on square footage and whether the decking underneath has softened from years of trapped moisture.
Mid-Century Tract Home Reroofs
The stucco tract homes around Commerce were built when built-up roofing was standard, so many still have original low-slope systems that were never designed for today’s heat and UV exposure. We tear down to the decking, inspect for soft spots and failed flashing at penetrations, and rebuild with architectural shingles or a single-ply membrane if the pitch is under 2:12.
Recover vs. Tear-Off Decisions
Some Commerce homeowners ask about layering new roofing over the old. In a dry basin climate, a full tear-off is almost always the better call when the decking has never been inspected, because this city’s heat plus trapped soot accelerates deterioration from the underside. We’ll show you what’s under the old layer and let you decide with the facts in front of you.
Flat Roof Replacement in Commerce
Flat Roof Replacement in Commerce is the bread-and-butter of this market – the warehouses, shops, small multi-family buildings, and dozens of mid-century homes with low-pitch or flat roofs all eventually need membrane replacement or a full recoat system. Expect $9,500 – $18,000 for a full tear-off and single-ply or modified-bitumen replacement, with coating-only options starting lower when the underlying membrane is still sound.
Single-Ply and Modified-Bitumen Systems
The roofing crews who work Commerce regularly know that cap sheet and coating break down faster here than in coastal or hillside cities. Soot from the I-5/710 interchange settles on low-slope roofs, mixes with what little moisture the basin gets, and bakes into the membrane under intense summer UV. We specify single-ply TPO or PVC and modified-bitumen systems based on the roof’s drainage and exposure, not based on which product is on sale.
Commercial Flat Roof Scope Changes
A fair number of flat-roof replacements in Commerce turn into decking jobs once the old membrane comes off. That’s not an upsell – it’s what happens when ponding water has been sitting on a built-up roof for a decade. We scope flat roofs honestly, show you the soft spots with photos, and give you a line-item quote so you know what’s changing before the crew starts pulling material.
Trusted Brands We Service in Commerce
We’re authorized to install and supply materials from seven manufacturers – GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. For Commerce customers, that means we can match the material to the building: an Atlas or Tamko architectural shingle on a tract home near Veterans Park, a GAF or Boral system on a flat-roof shop off Eastern Avenue. We stock common Commerce parts and materials locally where possible, which keeps turnaround tight when a tear-off reveals a deeper problem than expected. Seven leading brands, one straightforward recommendation.

AfterCommon Roof Replacement Problems We See in Commerce Homes
- Soot-caked cap sheet on low-slope roofs. Freeway and factory grime from the I-5/710 area settles on flat and low-pitch roofs, traps moisture, and shortens the life of cap sheet and coating. We see this on nearly every flat roof we tear off in Commerce.
- Ponding water and soft decking. Commerce’s older built-up roofs often drain poorly after years of thermal expansion opens seams and blisters the membrane. Once water sits, decking softens, and the job grows beyond what a simple recoat would fix.
- Failed flashing at penetrations. Mid-century tract homes and small multi-family buildings here have original flashing around vents, pipes, and low parapet walls that corrodes and separates over time. We flash every penetration to current spec on every replacement.
- Thermal expansion on original built-up roofing. Hot dry summers cycle these roofs hard – the membrane expands and contracts daily, opening seams that then collect grime and moisture. If the roof is old enough to have an original built-up system, it’s usually beyond repair by the time we see it.
Pricing for Roof Replacement in Commerce, CA
Residential asphalt shingle reroofs in Commerce run $7,800 – $14,200. Flat roof replacement runs $9,500 – $18,000 for a full tear-off and new membrane, with coating-only options starting lower when the decking and membrane are still sound. What moves the number: decking condition after tear-off (this is the biggest variable in Commerce), membrane type on flat roofs, roof size and pitch, and whether a crane or special disposal is needed for tear-off debris. We give written line-item quotes, and we don’t change the price once the job is scoped unless you ask to change the scope. Call (866) 217-3967 to schedule your free estimate.

FAQs About Roof Replacement in Commerce
Flat roofs in Commerce fail faster because the city sits in the warm, smoggy LA basin where freeway soot from the I-5/710 interchange and nearby factories settles on low-slope roofs, traps moisture, and bakes into the membrane under intense summer UV. This breaks down cap sheet and coating years faster than a coastal or hillside city would see. Call (866) 217-3967 and we’ll tell you whether your flat roof needs recoat or full replacement.
Compare them by material specification, not just price. Ask whether the bid includes tear-off, decking inspection and replacement if needed, drip edge, flashing at every penetration, ice and water shield in valleys, and a wind-rated nailing pattern. A cheap cap-sheet spec on a flat roof in Commerce will cost more within a decade than a single-ply job done right the first time. Call (866) 217-3967 for a line-item quote you can compare honestly.
Yes. Soot and grime from the I-5/710 corridor and local manufacturing settle on low-slope roofs and accelerate membrane and coating breakdown, so we lean toward single-ply TPO or PVC with a high UV and grime tolerance rather than a traditional built-up roof on flat commercial and multi-family stock. For residential shingle roofs, architectural shingles with stronger granule adhesion hold up better here than basic three-tab. Call (866) 217-3967 to talk materials.
Expect 110 – 130 mph wind ratings on architectural shingles installed to manufacturer spec – but only if the nailing pattern is actually followed. Commerce doesn’t see the extreme wind of mountain passes, but the basin does get strong Santa Ana gusts, and a roof nailed off-pattern won’t earn whatever rating is printed on the wrapper. We install to spec and show you the nailing pattern before the underlayment goes down. Call (866) 217-3967 for a free estimate.
Ponding water means the roof has a drainage problem, and whether you need replacement or recoat depends on what’s under the water. If the membrane is intact and the decking is dry, a recoat with proper slope correction may buy years. If the cap sheet is soot-caked, blistered, and the decking has softened, replacement is the honest answer. Call (866) 217-3967 and we’ll put a camera on it and show you what we see.
