We serve every Commerce ZIP code with a repair-first evaluation before any replacement is proposed. Call (833) 589-7850 and we’ll tell you what your roof actually needs – repair, replacement, or nothing yet.
Commerce isn’t like most of LA County when it comes to roofing. The city’s industrial footprint shapes how roofs fail here, and that changes what a proper replacement looks like. We work on residential homes along Bandini Boulevard and the older tracts near Rosewood Park, but we also handle low-slope commercial buildings along the 5 and 710 corridors. The same crew that inspects a three-bedroom house off Eastern Avenue can quote a warehouse re-roof off Slauson. That range of experience matters when you’re deciding whether to patch or replace.
Why Bedrock Roof Repair Is Commerce’s Preferred Roof Replacement Company
We’re honest about what we find. That’s the whole reason the name is Bedrock Roof Repair, not Bedrock Roof Sales. A targeted fix is a fully legitimate outcome when the roof still has service life left. When replacement is truly warranted, we quote it with the same directness – and we bring seven material brands to the table so the recommendation follows your roof and budget, not a supplier relationship.
Commerce homeowners and property managers keep calling us because we don’t hand off work. Alan Cofield leads the same team from first inspection to final nail. No subcontractor roulette. No new project manager halfway through. If you’re comparing bids, ask any contractor exactly who will be on-site and whether that changes mid-job. Then ask us.
We also understand Commerce’s permit and code landscape in a way a contractor from the other side of the county usually doesn’t. More on that below, because it directly affects your final price and whether your project closes cleanly.

Roof Replacement Contractor in Commerce
A Roof Replacement Contractor in Commerce has to handle two very different job types: residential shingle replacement on the city’s older tract homes, and commercial membrane work on the warehouses, trucking facilities, and industrial buildings that dominate the landscape. A roofer who only does houses will get lost on a flat commercial roof. A roofer who only does commercial won’t know what’s failing on a 1950s single-family near the Commerce Civic Center.
We do both. That matters because Commerce’s commercial roofs don’t fail the way residential ones do. Roof Replacement for a Commerce warehouse usually comes down to membrane breakdown from sun exposure and ponding water, not missing shingles. For a home, it’s aging asphalt shingles, failed flashing, and decking rot. Different failure modes need different skills.
Residential Roof Replacement
Most homes in Commerce were built mid-20th century. The roofs are aging out, and many have had multiple patch jobs over the years. We strip to the decking, inspect what’s underneath, replace rotted sections, and install the replacement per current wind and fastening requirements.
Commercial Low-Slope Replacement
These jobs run larger by an order of magnitude. Tear-off, re-sloping, new scuppers, and a Title 24-compliant membrane are the standard scope. We’ll walk you through the permit path and documentation before we ever start demo.
Asphalt Shingle Roof Replacement in Commerce
Asphalt Shingle Roof Replacement in Commerce homes is the most common residential project we quote, and the honest price range is $9,800 to $18,500 for a typical single-family house, depending on square footage, tear-off layers, and decking condition. Architectural shingles add roughly 12 to 18 percent over standard three-tabs but carry better wind ratings and longer material warranties.
On Commerce’s older tract homes, the condition of the decking is the wild card. Homes built in the 1950s and 1960s often have 1×6 or plywood decking that’s fine in places and soft around plumbing vents or old roof penetrations. A cheap quote assumes the decking is solid. Ours accounts for what we actually find after tear-off.
Architectural Shingle Options
We install architectural shingles from CertainTeed, Owens Corning, IKO, and Atlas. Each manufacturer publishes wind-rating documentation, and we include the product data sheet in your project file. That documentation matters in Commerce for insurance and resale purposes.
Underlayment and Flashing Standards
The difference between a compliant quote and a cheap one is often in the underlayment. We include ice and water shield under valleys and around penetrations on every Commerce replacement. Skipping it saves money upfront and leaks within a season or two.
Trusted Brands We Service in Commerce
We’re not married to one manufacturer. We install products from seven leading brands – GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral – because your roof conditions and budget should drive the recommendation, not our supplier agreement. For Commerce’s mix of residential shingle work and commercial membrane projects, we often specify CertainTeed or Owens Corning architectural shingles on homes, and Atlas or IKO products where wind rating and cost need to balance. Your roof, your numbers, our honest read on what fits. We keep standard materials staged for quick turnaround on Commerce jobs, so you’re not waiting on a warehouse delivery from across the county.

AfterCommon Roof Replacement Problems We See in Commerce Homes
- Failed decking underaged shingles. Commerce’s older housing stock means we regularly find water-damaged decking once shingles come off. A replacement that skips decking inspection is a replacement you’ll pay for twice.
- Ponding on low-slope and flat roofs. Winter storms pool water on flat roofs across Commerce’s industrial areas. If drains aren’t cleared and scuppers aren’t correctly placed, the membrane fails early and warranties get voided.
- Missing Title 24 documentation on commercial work. Commerce’s permit process requires a cool-roof reflectance data sheet on low-slope replacements. Contractors who skip this leave owners holding a project that can’t close its permit.
- Undersized wind fastener patterns. Homes near the open stretches along the 710 and 5 corridors get wind gusts that cheap nail patterns won’t hold against. We quote to the manufacturer’s wind-rated fastener schedule, not the minimum.

FAQs About Roof Replacement in Commerce
Yes. Commerce’s permit process for low-slope commercial roof replacement triggers a Title 24 cool-roof requirement that mandates a minimum aged solar reflectance of 0.63 for the membrane or coating. The product data sheet becomes a permit document. We include it in every commercial quote we issue in Commerce.
We specify architectural shingles rated for at least 110 mph wind resistance on Commerce homes, and we fasten to the manufacturer’s wind-rated nail schedule. Homes near open stretches along the 710 and 5 corridors benefit from the higher rating, and it’s not much more than the standard 90 mph product.
Lay them side by side and look for four things: decking replacement allowance, underlayment spec at valleys and penetrations, wind fastener schedule, and – for commercial roofs – whether a Title 24 reflectance data sheet is included. A cheap bid usually falls apart on the first two. A fair bid itemizes all four. Call (833) 589-7850 and we’ll walk you through the comparison.
Yes, and we’ve seen it work in Commerce. Proper documentation of the wind rating on shingles or the aged reflectance value on a commercial membrane gives an insurer something to underwrite favorably. We replaced a failed modified bitumen roof on a 40,000-square-foot warehouse off Slauson Avenue near the 710, where winter ponding had been patched for years. Our crew tore off to the decking, re-sloped two areas to new scuppers, installed a Title 24-compliant TPO membrane with a 0.65 reflectance, and documented the aged reflectance value for the owner’s insurer. The emergency calls stopped, and the building’s property manager used our compliance packet to support a premium credit.
Commerce sits in the LA Basin with hot, dry summers that bake flat commercial roofs and break down membranes and coatings. When winter rain comes, water pools anywhere drainage is inadequate. That standing water is what kills a low-slope roof here – not wind. We pay outsized attention to drains, scuppers, and re-sloping on every Commerce flat roof we replace. Call (833) 589-7850 for a free inspection and we’ll tell you what’s actually happening up there.
