Fast, Reliable Roof Replacement Across Commerce
Roof replacement in Commerce costs between $9,800 and $18,500 for a typical residential job, depending on whether the home needs a low-slope membrane system or architectural asphalt shingles. Most Commerce re-roofs take 2 to 5 working days once the tear-off starts, and because we carry materials from seven manufacturers, you’re not stuck with whatever one brand happens to have in stock. If you’re calling from the residential pockets near Commerce Way or the streets south of Washington Boulevard, we can usually be on site within a day or two to look at what’s going on. Call (855) 382-1073 and we’ll tell you straight whether a repair is enough or if replacement is the honest call.
Why Barnwood Roofing Is Commerce’s Preferred Roof Replacement Company
Commerce is not like neighboring residential cities. It’s an industrial city laced with warehouses, rail spurs, and distribution centers, and the housing stock reflects that history: small post-war tract homes with flat or shallow-pitch roofs, many of them carrying two or three layered roof systems from decades of patchwork repairs. We’ve worked enough of these homes to know what opening one up actually turns up. Ruben Calloway, our owner, built Barnwood around a simple principle: inspection first, recommendation second. We’ll tell you if a repair buys you five more years. And if it won’t, we’ll show you exactly why on the roof, not from a sales binder.
Part of what keeps Commerce homeowners calling us back is that our Roof Replacement work doesn’t start with a replacement pitch. It starts with a tear-off inspection. On older Commerce homes, the layers hide things: rotted decking, failed flashing at parapets, undersized framing that predates modern load codes. We price allowances for those discoveries up front, in writing, so the number on your contract reflects what we actually expect to find, not a teaser price that moves on day two.
Styles & brands we work with
Asphalt Shingle Roof Replacement in Commerce
Asphalt Shingle Roof Replacement in Commerce typically runs $9,800 to $14,200 on a modest tract home where the existing roof is already a shingle system and the decking underneath is sound. The job involves a full tear-off of the old shingles, inspection of the decking and flashing, new synthetic underlayment, and installation of the shingle system you choose, whether that’s a three-tab, an architectural laminate from Owens Corning, or a higher-end Atlas or CertainTeed line. On Commerce’s 1950s and ’60s homes, the first thing we check is whether the pitch actually supports shingles. Some of these roofs were built shallow enough that a membrane is the better long-term answer.
When Shingles Make Sense Here
A few Commerce homes do have enough slope for a proper shingle system, especially small gable sections on the post-war tract houses off Eastern Avenue. If your roof drains well, has at least a 3:12 pitch, and the decking is structurally clean after a tear-off inspection, shingles give you the most options per dollar across material tiers.
What the Tear-Off Usually Reveals
On these older Commerce homes, it’s common to find two or even three existing shingle layers. That layering hides decking rot around the plumbing vents and ridge. We factor a tear-off inspection into every quote, and we write framing repair and decking replacement into the contract as a priced allowance so the final number doesn’t surprise you mid-job.
New Roof Installation in Commerce
New Roof Installation in Commerce for a house that’s getting a first replacement, or for an addition or new build, runs $12,000 to $18,500 depending on square footage and system type. This is the job where we’re not just stripping old material; we’re often correcting drainage, rebuilding parapet flashing, and bringing the roof assembly up to current code. On Commerce’s residential flat and low-slope homes, a new installation usually means a TPO membrane or a built-up roof over new insulation board, with new edge metal and scupper detailing. That’s the difference between a roof that lasts 20 years and one that ponds in the first winter.
Low-Slope Replacements on Tract Homes
The residential pockets near Bandini Boulevard and south of Slauson were built when builders treated flat roofs as a cost-saver, not a performance choice. Replacement here means addressing the whole assembly: insulation, drainage slope, flashings at parapets and pipes, and a membrane rated for the Los Angeles basin’s UV load. We walk Commerce homeowners through membrane options from GAF and Others alongside traditional shingle systems where the pitch allows, so you make the call based on your roof, not our inventory.
New Construction Work in Commerce
Commerce also has occasional new residential and small multi-family builds, and we handle those from rough framing through final inspection. On new construction, the roof plan is set by the engineer and the building department, and we work through those drawings with the contractor or homeowner directly. Permits are pulled, inspections scheduled, and the roof is built once, correctly.
Trusted Brands We Service in Commerce
Because we’re not tied to a single manufacturer, we can recommend from seven brands and pick what actually fits your Commerce roof. For the low-slope and flat systems that dominate here, GAF’s commercial-grade TPO and CertainTeed’s membrane lines are common choices. For the steeper sections where shingles work, Owens Corning architectural laminates and IKO lines give you solid mid-tier options, while Atlas and Boral cover the higher-performance end. We keep local stock and order specifically for Commerce jobs, which means a faster turnaround than a shop that has to special-order everything. The right material for your roof, not just what we stock.

AfterCommon Roof Replacement Problems We See in Commerce Homes
- Layered tear-offs hide real damage. Most 1950s-’60s tract homes in Commerce carry two or three existing roof systems. Once we tear off to the decking, we often find rotted sheathing and undersized framing that a quick-look bid never saw. That’s why our quotes include a priced allowance for framing and decking repair, written out before demo starts.
- Parapet and penetration flashing fails first. On flat and low-slope roofs, the membrane often looks fine while water is getting in at parapet walls, vent pipes, and utility penetrations. Reusing aged flashing during a replacement sets the new roof up to fail within a few seasons of Commerce heat and winter rain.
- Drains and scuppers pack with grit and diesel soot. The rail corridors and freeway traffic around Commerce throw fine particulates that settle on roofs and wash into drains during the first storm. A new low-slope membrane still ponds and leaks if those drains aren’t corrected as part of the job.
- UV degradation hits flat membranes hard. Basin summers with months of direct sun cook unprotected TPO and built-up surfaces. A replacement that skips a reflective surface or proper insulation board shortens the membrane’s life, especially on Commerce’s larger residential and small commercial buildings.
Pricing for Roof Replacement in Commerce, CA

FAQs About Roof Replacement in Commerce
Because on most Commerce tract homes, the old roof hides layers of previous installations, rotted decking, or failed framing that no one can see until the tear-off is done. Our quotes include priced allowances for the repairs we expect to find, based on what we’ve seen on other homes in the same neighborhoods, so the contract reflects reality from day one. If something genuinely unforeseen appears after the tear-off, you see photos and approve a written change order before we do any extra work. Call (855) 382-1073 and we’ll walk you through how we price a Commerce replacement before you sign anything.
Most Commerce homes need a low-slope membrane system, not architectural shingles, because the original post-war builds were designed with flat or shallow-pitch roofs. Shingles only perform correctly at a 3:12 pitch or steeper, and many Commerce roofs don’t meet that. Where a section of roof does have enough slope, shingles can work, and we’ll tell you which sections qualify. Otherwise we recommend a TPO or built-up system with proper drainage.
We price by line item: tear-off, decking and framing allowance, underlayment or insulation board, membrane or shingle material, flashing, drainage correction, and permit costs. That lets you compare our number against another contractor’s number item by item, instead of eyeballing a single lump sum that hides what’s actually included. For a typical Commerce home, expect $9,800 to $14,200 for shingle work and $12,000 to $18,500 for a low-slope system. Call (855) 382-1073 for an exact written estimate on your roof.
Clogged drains and scuppers are the most common cause, because grit and diesel soot from the rail and freeway corridors along the I-5/710 junction settle on roofs and pack into drainage openings during the first winter storm. That water ponds and finds the weakest flashing point at a parapet or penetration. During a replacement, we correct the drainage path and replace aged flashing, which is what actually stops the leak.
Yes, a roof replacement in Commerce requires a building permit, and the inspection that comes with it often triggers code upgrades to framing, insulation, or drainage that the original roof never met. We pull the permit, schedule the inspections, and build those upgrades into the contract as known costs, not surprises. A contractor who says you can skip the permit is setting you up for a failed resale inspection and an insurance headache. Call (855) 382-1073 and we’ll handle the permit process as part of the estimate.
