Fast, Reliable Roof Replacement Across Commerce
Roof replacement in Commerce typically runs $9,800 – $18,500 for a standard single-story post-war home, with architectural asphalt shingles on the higher end and basic three-tab on the lower. Most residential jobs take three to five working days once materials land. If you’re off Bandini Boulevard, near the Citadel, or tucked into the residential streets east of Eastern Avenue, call (866) 361-0798 and we’ll come out, walk the roof, and give you a written line-item estimate that names exactly what we’re replacing and what it costs.
We work this area regularly. Our Roof Replacement crews know the 1950s and 60s tract homes here, the low-pitch roofs, and the flat commercial buildings sitting three blocks from residential streets. That matters because Commerce doesn’t roof like most of LA County. The housing stock is old, the freight corridors are close, and what hides underneath a worn shingle roof here is almost never just more shingle wear.
Why Ridge Cap Roof Repair Is Commerce’s Preferred Roof Replacement Company
Noel Cardenas runs our crews, and his approach shapes every job we take in Commerce: we inspect before we recommend. That means when a homeowner off Gage Avenue calls us thinking they need a full roof, we don’t quote a replacement over the phone. We get on the roof, check the decking, test for soft spots, look at the underlayment, and only then tell you whether repair makes sense or replacement does. Seven manufacturers. One crew. That’s the whole model: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral, so the material recommendation follows the roof, not our inventory.
Commerce homeowners tell us they chose us because the estimate accounted for things other roofers skipped. One recurring comment: another bid quoted a shingle layover and never mentioned the near-flat pitch or the grit-clogged drains. We don’t lay over damaged decking. We strip, expose, and price the real scope before anything gets nailed down.
Styles & brands we work with
Asphalt Shingle Roof Replacement in Commerce
Asphalt Shingle Roof Replacement in Commerce is the most common residential re-roof we perform here, and for good reason: most homes in the 90101 zip were built during the post-war tract boom, and the original composition shingles are either failing now or already replaced once with materials that didn’t account for Commerce’s soot load. A full tear-off and replacement with architectural shingles on a typical 1,100 – 1,400 square foot home runs $10,500 – $15,500. Three-tab runs lower, $9,800 – $12,800, but we rarely recommend it on low-pitch roofs where water sits longer than the shingle can shed.
What determines the final number isn’t the shingle price. It’s what we find when the old roof comes off.
Tear-Off and Decking Inspection
We strip to the deck. On Commerce homes from the 50s and 60s, we routinely find plywood or skip sheathing that’s softened from years of ponding water where clogged drains sat wet through winter. Every soft panel gets marked and added to a written change allowance before we install anything new.
Underlayment and Waterproofing
Low-pitch roofs need better than felt paper. We upgrade to synthetic underlayment or ice-and-water shield in the valleys and along the eaves on these homes, because a near-flat deck with diesel soot in the drains is exactly where leaks start. That’s a specific Commerce problem, not a generic roofing one.
New Roof Installation in Commerce
New Roof Installation in Commerce splits into two very different worlds. We do brand-new residential roofs on additions, ADUs, and the occasional ground-up build in the residential pockets, plus full re-decks where an older home’s framing is too far gone to accept new shingles. A new complete roof system on a Commerce home, including decking correction, underlayment, shingles, flashing, and ventilation, runs $14,000 – $22,000 depending on square footage and access. ADU and addition roofs run smaller but carry the same requirement: correct pitch, correct waterproofing, correct flashing.
On the commercial side, where the warehouses and Citadel-adjacent retail buildings sit, we install and replace flat and low-slope roofing: modified bitumen, TPO, and built-up systems. Those jobs are quoted by square footage and system type, and we handle them with the same inspection-first rule.
Residential Reroof and Redeck
When a Commerce roof has failed decking across more than about a quarter of its area, a roof-over is off the table. We recommend full redeck and a complete new system. The framing underneath gets inspected at the same time, because once the deck’s open, code issues become visible, and we’d rather surface them on day one than after the first inspection.
Flat and Low-Slope Systems
Commerce’s commercial and light-industrial buildings along Telegraph Road and the 710 corridor need flat-roof work that most residential roofers won’t touch. We install and replace modified bitumen and TPO membranes, and we inspect drains and crickets because in this city, a clogged drain on a flat roof means ponding, and ponding means a failed roof in half the time.
Trusted Brands We Service in Commerce
We install and service seven manufacturer lines: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. In practical terms for a Commerce homeowner, that means we can match a specific shingle profile from the neighborhood’s original look, or pair a heavier architectural shingle with the heavier soot load near the freight corridors. We don’t push one brand. We pick the one that fits the roof pitch, the exposure, and the budget. For most Commerce homes we lean on CertainTeed Landmark and Owens Corning Duration lines, and we spec IKO and Atlas where a tighter budget still needs a full tear-off. Parts and materials are sourced regional, so a Commerce job doesn’t wait on coast-to-coast shipping.
Common Roof Replacement Problems We See in Commerce Homes
- Premature granule loss from freight-corridor soot. Diesel exhaust and refinery fallout settle into the shingle surface and dry out the asphalt. Roofs off the 710 and I-5 corridors look fifteen years older than their calendar age, and the grit piles up in gutters and drains.
- Low-pitch decks that pond water. Most 1950s-60s tract homes here were built with a pitch too low for standard three-tab. Water sits, underlayment fails, decking rots. A roof-over hides it. A full replacement fixes it.
- Original underlayment that’s dished and cracked. Even where shingles look decent, the felt underneath is often the original 1950s material. We pull it, and it crumbles. That’s why we never quote a layover on these homes.
- Soft decking around drains and scuppers. Flat-roof sections and near-flat residential roofs both suffer where drainage clogs with soot and grit. The wood around the drain is the first to go, and it’s always found after stripping, never before.

FAQs About Roof Replacement in Commerce
Distance from the freight corridors is the difference. Homes near the 710, I-5, and the industrial belt along Telegraph Road take a constant dusting of diesel soot and refinery fallout that darkens shingles and accelerates granule loss. A house eight blocks further from the freeway won’t show the same buildup. If your roof looks blackened and gritty, it’s not just age; it’s location.
Call (866) 361-0798 and we’ll tell you whether what you’re seeing is surface staining or a roof at the end of its function.
Almost always, yes, and that’s why we quote differently. We write decking-repair allowances into the estimate based on what we can see and what we know these roofs typically hide. On a 1958 tract home off Telegraph Road, our crew stripped the original shingles and found the decking softened and the old underlayment dished exactly where soot-clogged drains had ponded water. We walked the homeowner through every soft panel, marked it, and priced the redeck in writing before nailing down a single new shingle. That’s how we handle every low-pitch Commerce roof. No surprises, because we price the surprise before it becomes one.
If you want an estimate that plans for what’s under the shingles, call (866) 361-0798.
It can. When the decking comes off and the framing is exposed, an inspector may flag undersized rafters, outdated wiring run through the roof plane, or missing shear panels, and those corrections become part of the permit scope. We plan for that. We inspect the framing when we strip, we write allowances for the most common Commerce code triggers, and we price any upgrade in writing before we proceed. You don’t find out at the final inspection. You find out day one.
Call (866) 361-0798 and ask us what your specific roof might trigger. We’ll tell you straight.
Look at the line items, not the bottom number. Compare decking-repair allowances, underlayment type, whether ice-and-water shield is included, whether drip edge and flashing are listed, and whether the bid includes the permit and inspections. A cheaper Commerce bid that assumes a clean deck will likely hit you with change orders once the tear-off happens. Our estimates carry allowances for exactly what these post-war low-pitch roofs hide, so the comparison is honest from the start.
Bring us the other bid. Call (866) 361-0798 and we’ll walk through the line items with you.
Yes. Commerce’s residential streets were built with specific shingle colors and profiles from the 1950s and 60s, and because we work with seven manufacturers, we can match the original look while installing a heavier, better-warrantied architectural shingle. What we won’t do is put a period-correct shingle on a low-pitch deck that can’t shed water properly. The look matches, the waterproofing and ventilation underneath get upgraded to current code, and the roof works better than the one that came off.
Call (866) 361-0798 and we’ll bring sample boards that fit both the street and the pitch.
