Fast, Reliable Roof Replacement Across Commerce
Roof replacement in Commerce means something different here than it does two miles away in East Los Angeles or Montebello. This city runs on warehouses, distribution centers, and cold-storage facilities, and the roofing trade reflects that. A full Roof Replacement on a Commerce property usually falls into one of two camps: a post-WWII bungalow with a low-slope tar-and-gravel roof, or an industrial flat roof with a dense field of HVAC and refrigeration penetrations. Most asphalt shingle tear-offs on Commerce homes run $9,500 to $18,500 depending on square footage and decking condition. Flat membrane work on larger buildings runs $6.50 to $12 per square foot. Call (945) 303-9821 for a written price before any work starts.
Why Tilehurst Roofing Is Commerce’s Preferred Roof Replacement Company
We answer the phone. That sounds small, but in a city where property managers are juggling tenants, refrigeration schedules, and security gates, a roofer who goes to voicemail is a roofer who loses the job. Tilehurst Roofing’s Roof Repair - Commerce customers talk to a live person at (945) 303-9821, 24 hours a day. No callback queue. No “we’ll get back to you Monday.” When a cold-storage warehouse near Bandini Boulevard has a membrane tear during a Santa Ana event, someone needs to hear from us right then.
Our crews know the rhythm of Commerce. We understand that replacing a roof over an active food-processing line means coordinating tear-off around production schedules, not the other way around. Greg Holloway, who leads our team, has built the Kingswell approach around one principle: put the price in writing before the first nail. That holds whether we’re reroofing a 1948 ranch house near the city center or a 40,000-square-foot distribution building off Eastern Avenue.
Every Tilehurst job is covered by the 365-Day Done Right Promise. If it’s not right, we come back and make it right, for a full year, at no charge. Background-checked, uniformed technicians do the work. You know who’s on your roof.
Reroofing in Commerce
Reroofing in Commerce means removing the existing roof system down to the decking and installing a new one, rather than layering new material over tired old layers. On the small residential pockets around the city center, most original roofs are low-slope built-up or tar-and-gravel systems from the 1940s through 1960s. Those decks were never framed for heavy shingle loads, and many have settled over the decades. A proper reroof here starts with a deck assessment. Most Commerce bungalow reroofs run $11,000 to $17,000 with architectural shingles and new underlayment, or $14,000 to $22,000 when we need to replace rotted decking sections, which is common on these homes.
Decking and Drainage First
On a 1950s ranch house in Commerce, the decking is often the weak link. Age, ponding water, and decades of patched leaks leave sections soft or delaminated. We inspect every sheet before we install anything. If we find rot, it’s added to the written scope with a price you approve before we proceed. Nothing changes the price once work starts unless you ask for it.
Matching the Original Roofline
Many Commerce homeowners want a roof that still looks like their house, not a generic new roof dropped on top. We match low-slope profiles where they exist, and we detail drip edge and fascia so the finished job looks like it belongs. The Kingswell Way: say the price before the work, show up in the window we gave, leave the place cleaner than we found it, put the guarantee in writing, come back if it fails.
Flat Roof Replacement in Commerce
Flat Roof Replacement in Commerce is the bread and butter of this city’s roofing volume, and it’s a different trade than shingle work. Most of Commerce’s roofable square footage sits on warehouses, distribution centers, and manufacturing buildings with TPO, EPDM, or modified-bitumen membranes. The residential bungalows near the center share the same low-slope reality but on a smaller scale. Flat roof replacement here runs $6.50 to $12 per square foot depending on membrane type, insulation requirements, and how many penetrations the existing roof carries. A 20,000-square-foot warehouse typically lands between $130,000 and $240,000. A small low-slope house roof can run $15,000 to $30,000.
Penetration Detailing on Industrial Buildings
Commerce’s warehouses and cold-storage facilities carry dense fields of rooftop HVAC and refrigeration units. Each penetration is a potential leak. Our crews detail every curb, pipe, and vent with manufacturer-specified flashing and sealant, then check the field of the membrane separately. The goal is a roof that holds at the seams and edges, which is where Commerce roofs actually fail.
Working Around Production Schedules
You can’t shut down a cold-storage line for a week. We plan tear-off sections and phasing around your operations, and we sequence work so occupied spaces stay dry. That planning is part of the written estimate, not an afterthought. Greg Holloway’s teams have managed this on food-processing facilities across the LA Basin, and Commerce’s industrial density means we do it here constantly.
Trusted Brands We Service in Commerce
Tilehurst Roofing installs and services roof systems from seven leading manufacturers, so the product fits the building. For Commerce’s flat and low-slope stock, we commonly recommend GAF TPO and Atlas membranes for their heat-reflective surfaces, which matters when summer roof temperatures push past 150°F on dark industrial roofs. For the shingle reroofs on Commerce’s ranch homes, CertainTeed and Owens Corning architectural lines hold up well under inland sun. We stock common flashing and membrane accessories locally for Commerce jobs, which cuts lead time on repairs and keeps replacement schedules moving. The material choice is yours, and the price is written before anything gets ordered.
Common Roof Replacement Problems We See in Commerce Homes
- Ponding water on aging tar-and-gravel roofs. The post-WWII low-slope homes near the city center were built when tar-and-gravel was the standard. Decades later, the gravel wears thin, the tar gets brittle, and water pools instead of draining. The failure is usually at seams and penetrations, not the field of the membrane.
- Leaks around rooftop HVAC and refrigeration units. On Commerce warehouses, the roof itself might be fine, but the flashing around mechanical curbs fails. Cheap sealant, value-engineered details, and years of vibration from running equipment create chronic leak points that only show during heavy rain.
- Santa Ana wind uplift on large flat roof planes. Commerce’s sprawling warehouse campuses have huge, unobstructed roofs. High winds peel back under-attached membrane edges before the material itself fails. We increase fastener density at perimeters and corners on every flat roof replacement in Commerce.
- Premature degradation from 150°F+ surface temperatures. Inland Commerce doesn’t get the marine layer relief that coastal cities get. Dark membranes and dark shingles cook. We spec reflective membranes and lighter shingle colors where the home’s style allows, and we use underlayment rated for sustained high heat.
Pricing for Roof Replacement in Commerce, CA
Here are honest numbers for Commerce’s market. Residential shingle reroofs: $9,500 to $18,500 for a typical bungalow. Flat membrane work on small low-slope homes: $15,000 to $30,000. Commercial flat roof replacement: $6.50 to $12 per square foot, so a 20,000-square-foot warehouse runs $130,000 to $240,000. What moves the price: decking condition, membrane type, insulation code requirements, and penetration count. On an industrial roof with 40 HVAC and refrigeration curbs, the detailing cost is real, and we itemize it rather than bury it. Every estimate is free, written, and fixed before we order materials. Call (945) 303-9821 to schedule yours.
Our crew recently tore off ponding tar-and-gravel over original decking on a 1948 ranch house near the city center and rebuilt it as a low-slope membrane system. We installed new ice and water shield at the valleys, sealed every HVAC and plumbing penetration, and finished the drip edge and fascia before rolling out the membrane. The homeowner’s leak complaints during Santa Ana wind events stopped, and the flat profile matched the original roofline rather than forcing a pitched framing change. That’s the job done right.

FAQs About Roof Replacement in Commerce
Yes. We phase the tear-off in sections and coordinate with your production schedule so occupied spaces, refrigeration lines, and loading docks stay operational throughout the job. This is standard practice for our Commerce commercial work, and it’s built into the written estimate. Call (945) 303-9821 to walk through phasing for your building.
We check the existing drainage first: scuppers, interior drains, and slope. If the deck sags, we correct it as part of the replacement scope. Then we install membrane with proper seam detailing and, where needed, tapered insulation to move water off the roof. Ponding that stays for 48 hours is a failure in progress, and we design against it. Call (945) 303-9821 for a drainage assessment.
Mostly failed or missing flashing details. In Commerce, the sheer density of rooftop units means more penetrations per square foot than in residential neighborhoods, and each one is a potential leak if the flashing was value-engineered, poorly sealed, or just aged out. We detail every curb, pipe, and vent to manufacturer spec and check them again before we leave. Call (945) 303-9821 to have your penetrations inspected.
They do. Large flat roof planes on warehouses and distribution centers can act like sails. Under-nailed edges peel back, and membrane seams open under sustained uplift. We increase fastener spacing at perimeters and corners on every Commerce flat roof replacement, and we verify attachment before covering any seam. Call (945) 303-9821 for a wind-uplift review on your roof.
The written estimate includes every line item: tear-off, decking repair, membrane or shingle material, penetration detailing, drip edge, fascia, and disposal. Before we order anything, you have a fixed number in writing. Changes only happen if you request them, and those get their own written approval. On high-end work with long-lead materials like custom architectural shingles or specialty membranes, the schedule is driven by lead times, not labor, and we set that expectation up front. Call (945) 303-9821 for your written estimate.
