AfterFast, Reliable Roof Replacement Across Commerce
Roof replacement in Commerce usually lands between $12,000 and $45,000 for residential asphalt work, while a commercial flat membrane system on one of the city’s tilt-up warehouses runs $8-$14 per square foot depending on insulation and cool-roof requirements. You’ll see your exact number in writing before any work starts. We know Commerce’s roof stock better than most crews working here, because we’ve spent years pulling core samples through failed tar-and-gravel systems and replacing them with Title 24-compliant membranes that actually hold up. If your roof is leaking, blistering, or just aging past its useful life, call Birchbark Roofing at (424) 766-4937 and we’ll start with a written evaluation, not a sales pitch.

Why Birchbark Roofing Is Commerce’s Preferred Roof Replacement Company
Commerce is an unusual roofing market. The city’s industrial tilt-up buildings vastly outnumber its modest residential enclave, and the failure modes here are different from what a Montebello or Bell Gardens roofer sees on a daily basis. We’re familiar with the dark membrane roofs that sit over the LA Basin heat corridor and bake past 170°F every August. We know the BUR systems that have been patched five times instead of stripped once. That local fluency changes how we bid, what we specify, and how long the work takes.
Our crews arrive in uniform, background-checked, and they treat your building like someone still works in it. Shoe covers at every entry, drop cloths through walkways, and a photo of the completed clean-up before we leave. The 365-Day Done Right Promise covers every replacement we perform. If it’s not right, we make it right. Erik Lindgren leads the team, and he’s the one who walks your roof before any estimate is finalized.
We also work with materials from GAF, CertainTeed, Owens Corning, Tamko, and Boral, so you’re not locked into a single manufacturer’s spec. For Commerce’s flat-roof work, the right membrane and fastener combination matters more than the brand sticker. We’ll show you why in the estimate.
Asphalt Shingle Roof Replacement in Commerce
Asphalt Shingle Roof Replacement in Commerce applies to the smaller residential and mixed-use structures in the city, mostly mid-century wood-frame homes clustered near the center. These roofs handle Commerce’s heat differently than the big industrial decks. Shingle slopes shed heat faster than a flat membrane, but the relentless August sun still bakes granules and dries out sealant tabs. When we replace an asphalt roof here, we check the deck for dry rot from old leaks, re-nail to current code, and install a system that breathes properly under a Southern California sun that doesn’t quit.
What the job involves on a Commerce home
You’ll get a tear-off of the old shingle layer, a deck inspection, new underlayment, drip edge, and architectural or three-tab shingles depending on your budget. We protect the yard and walkways with tarps. If your family has a dog, we coordinate the door schedule so the crew isn’t always coming through the side gate while the dog is out. Every job ends with a clean-up photo.
When it makes sense to replace instead of patch
Residential roofs in Commerce typically last 18 to 25 years. If you’re past year 20 and seeing granules in the gutter, curling tabs, or leaks around vents, a patch buys months, not years. A full replacement with a written price up front usually costs $12,000 to $22,000 for a typical Commerce home, but the higher end of that range covers the architectural shingle upgrades and deck repairs we commonly encounter.
New Roof Installation in Commerce
New Roof Installation in Commerce means two very different things depending on the building. On a residence, it’s a full system built from the deck up: framing if needed, sheathing, underlayment, shingles, flashing, and ventilation. On a Commerce warehouse, it means a new membrane or metal system installed over a properly prepared deck, often with tapered insulation to correct ponding water. You can see why the price gap matters: a 1,800-square-foot home might run $15,000 to $28,000, while a 50,000-square-foot industrial roof can exceed $500,000 when you factor in insulation, fasteners, and cool-roof coating.
Residential new construction and full builds
For a new build or an addition in Commerce, we install the roof as part of the framing timeline, before interior finishes. It pays to bring us in early. Erik reviews the plans and specs the right substrate and fastener package from day one, so you’re not retrofitting drainage or ventilation after drywall is up.
Commercial and industrial new installs
On Commerce’s tilt-up buildings, the new roof is a TPO, EPDM, or modified bitumen system that meets Title 24 cool-roof standards. We edge out old flashing, replace deteriorated wood blocking, and use stainless fasteners at every penetration. That’s the difference between a roof that lasts 25 years and one that needs a re-coat every six.
Trusted Brands We Service in Commerce
We stock common materials for Commerce work, which means a faster turnaround when you need a repair or a full replacement. For flat and low-slope commercial systems, we specify TPO and EPDM membranes from GAF and Tamko depending on the deck and the building’s solar load. For residential and mixed-use work, we use asphalt shingles from GAF and Tamko, with Boral available for tile profiles. The brand matters less than the installation, but we choose manufacturers with proven performance in hot, urban environments. If your existing roof is under manufacturer warranty, we’ll note what’s still covered before we quote the replacement.
Common Roof Replacement Problems We See in Commerce Homes
- Multi-layer tar-and-gravel roofs hiding moisture. Many of Commerce’s 1960s-1980s built-up roofs have been patched repeatedly without a full tear-off. Core samples frequently reveal saturated insulation board that rusts steel decking from below and causes any new re-coat to blister within one season.
- Thermal cycling stress on dark flat membranes. The urban heat island over Commerce pushes rooftop temperatures past 170°F in summer. Expansion and contraction cycles cause seam separation and embrittlement within 8 to 10 years, far sooner than a shaded residential slope would see.
- Title 24 cool-roof compliance issues. We see replacements where the contractor skipped the cool-roof cap sheet or used a non-compliant coating. The inspector flags it, and the owner is forced into a second roof job after re-occupying the building. That’s an avoidable five-figure mistake.
- Failed flashing at penetrations. Commerce’s industrial roofs are dense with vents, curbs, and HVAC units. When the old flashing detail isn’t stripped and rebuilt with compatible material, those penetrations leak first, usually within the first year after a re-coat.
Pricing for Roof Replacement in Commerce, CA
Residential asphalt shingle replacement in Commerce typically runs $12,000 to $28,000 depending on square footage, deck condition, and shingle grade.

FAQs About Roof Replacement in Commerce
Core samples are the only reliable way to tell. If moisture in the insulation board exceeds a certain threshold, or if there are multiple existing membrane layers, a re-coat will peel and blister within one season. We pull cores before recommending anything, and you’ll see the lab results alongside our written quote. Call (424) 766-4937 and we’ll set up the testing.
Yes. For most commercial roof replacements over occupied conditioned space, Title 24 requires a cool-roof compliant surface that meets minimum solar reflectance and thermal emittance values. In Commerce, where rooftop temperatures exceed 170°F, this isn’t a paperwork formality. It’s the difference between a building that stays tolerable and one that radiates heat into the workspace all afternoon. We specify compliant TPO or coated systems on every replacement.
We typically specify a full tear-off to the concrete deck, followed by a tapered insulation package and a TPO membrane with high solar reflectance. The old BUR layers come off completely, because leaving them traps moisture and voids the new membrane warranty. Stainless fasteners at every penetration complete the system. This is the most durable replacement path for Commerce’s aging tilt-up stock.
Plan on three to six weeks from tear-off to final inspection. The timeline depends on how many membrane layers we’re removing, whether the insulation board needs full replacement, and the number of penetrations requiring new flashing. We keep the building operational wherever possible and sequence the work by section, using drop cloths and barriers to protect active work areas. You’ll get a projected schedule with your written estimate.
Yes. Our crews work on Commerce’s large-span flat and low-slope roofs regularly, and we stock the fasteners, flashing, and membrane materials these buildings require. We’re background-checked, uniformed, and familiar with the permitting and Title 24 documentation process specific to this city.
