AfterFast, Reliable Roofing Company Across Commerce
If you own a home in Commerce, you already know roofing here works differently than it does in Pico Rivera or Montebello. The residential streets near the city center are lined with post-WWII bungalows and ranch homes, many still carrying their original low-slope roofs. Those roofs pond water. They leak at aged tar-and-gravel surfaces. And they need a roofer who understands that a Commerce lot rarely gives you room to stage materials or park a dumpster without a plan. Our crews work Commerce every week, we know the narrow streets and party walls, and we answer the phone at (945) 303-9821 when you call.
This page is written for homeowners in Commerce who need straight answers about roof repair and replacement, what it costs here, and how a tight lot changes how the work gets done.
Why Tilehurst Roofing Is Commerce’s Preferred Roofing Company
Tilehurst Roofing operates as part of the Kingswell family of roofing companies, founded in 2000. Greg Holloway leads our Commerce-area work, and he has spent years on roofs exactly like the ones packed tight along Commerce’s residential streets. We’re not a franchise that drops a different crew on every job. The people who quote your roof are the same people who run the crew, and every Commerce job starts with a written price before any work begins.
We hear the same story from homeowners all over Commerce: a contractor showed up late, changed the number at the door, or finished a repair that failed within a month. That’s why every repair we do in Commerce carries a written guarantee, delivered before the crew leaves the property. If a repair fails inside the guarantee period, we return at no charge under the 365-Day Done Right Promise. A live person answers our phone 24 hours a day, 7 days a week. No voicemail queue. No waiting until Monday.
Our Roofing Company team stocks materials suited to Commerce’s specific housing stock, from membrane products for low-slope bungalows to metal systems for detached garages and patio covers. We know which side streets off Washington Boulevard and Slauson Avenue are too tight for a full-size dumpster, and we price the job accordingly from the start.
Metal Roof Installation in Commerce
Metal Roof Installation in Commerce is a growing choice for homeowners on the city’s tight residential lots, not just for the warehouse campuses that dominate the industrial districts. Commerce’s inland LA Basin location pushes summer roof-surface temperatures well above 150°F. Traditional asphalt shingles absorb that heat and degrade faster. A standing-seam metal roof reflects more heat, handles Santa Ana wind uplift better on low slopes, and typically lasts 40 to 60 years with minimal maintenance. Metal Roof Installation on a Commerce home runs between $15 and $28 per square foot installed, depending on panel profile, existing decking condition, and access constraints on the lot itself.
Standing Seam Panels for Bungalows
On a 1950s ranch near the Commerce city center, a standing-seam panel system gives you a clean, low-profile roof that sheds water efficiently even at slopes under 3:12. We often install metal over the original sheathing after addressing any soft decking, which keeps tear-off debris off a narrow street where staging space barely exists. On a typical 1,200-square-foot Commerce bungalow, expect a full metal roof to run $18,000 to $34,000.
Metal Retrofit Over Flat Membranes
Many Commerce homes combine a low-slope main roof with a detached garage or patio cover sharing the same failing flat membrane. A metal retrofit over an existing membrane works well when the substrate is sound and adds decades of service without a full tear-off. The cost runs $10 to $16 per square foot, and we handle the drainage slope corrections so water never ponds at the rear wall again.
Residential Roofing in Commerce
Residential Roofing in Commerce centers on the small pockets of post-WWII wood-frame bungalows and ranch-style homes clustered near the city center. These houses were built between the 1940s and 1960s, and many still wear their original low-slope roofs. The signature failure is ponding: water sits on the flat surface, works its way into aged tar-and-gravel or roll roofing, and rots decking over time. Residential Roofing in Commerce typically runs $9 to $14 per square foot for a full tear-off and replacement, with membrane systems like TPO or modified bitumen on the low-slope sections and shingles or tile on any pitched additions.
Full Roof Replacement on Tight Lots
A full replacement on a Commerce bungalow means staging materials in two small street drops instead of one big delivery, hand-carrying squares to the back of the property, and renting a spot for the dumpster off the shared driveway approach. We price all of that into the written estimate before work starts. Most Commerce residential replacements run $11,000 to $22,000 depending on square footage and decking repair.
Low-Slope Membrane Systems
For the original flat or near-flat sections so common on Commerce homes, TPO and modified-bitumen membranes are the practical choice. TPO reflects heat better than dark tar-and-gravel, which matters in a city where summer rooftop temperatures exceed 150°F. Modified bitumen costs $7 to $12 per square foot installed and handles the ponding-prone low slopes well when the drainage is corrected during tear-off.
Trusted Brands We Service in Commerce
We install and repair materials from GAF, Atlas, and Tamko, along with four other major manufacturers, so the product fits your home rather than whatever happens to be on the truck. If you have an existing GAF membrane on a Commerce garage roof, we stock compatible flashing and repair materials locally and can get replacements quickly. The same holds for Atlas shingles on pitched additions. You get genuine choice across seven manufacturers, and we never push a house brand.
Common Roofing Company Problems We See in Commerce Homes
- Bidding a Commerce bungalow like a standard pitched-roof job. A roofer quotes the roof but forgets the lot: no street parking for materials, no place for a dumpster, no route to hand-carry squares to the rear of the property. The price goes up at the door. We include access costs in the written estimate from day one.
- Ignoring party-wall protocol on close-set lots. Near the Commerce city center, many homes share a wall with the neighbor. Tearing into shared flashing without written notice and a photo record of existing conditions leads to disputes and exposed walls during tear-off. We photograph the neighbor’s side and document everything before work begins.
- Treating the main roof as the whole scope. On Commerce homes, the detached garage, patio cover, and shed roof often share the same failing flat membrane. Leaving them out of the bid guarantees a callback. We scope the entire property and price it as one job.
- Underestimating Santa Ana wind uplift on low-slope roofs. The large unobstructed roof planes on Commerce’s warehouses are well known, but residential low slopes face the same wind. We verify fastener patterns and edge details to keep membranes in place during wind events that push 60 mph gusts through the LA Basin.
Pricing for Roofing Company in Commerce, CA
What does roofing actually cost in Commerce? For a full residential tear-off and replacement on a typical post-war bungalow, expect $11,000 to $22,000. A membrane-only overlay on a low-slope roof runs $7 to $12 per square foot. A full metal roof on a 1,200-square-foot home lands between $18,000 and $34,000. Roof repairs on older Commerce homes run $450 to $1,800 depending on the leak’s location and the decking damage beneath. The factors that move the number most on a Commerce job are lot access, party-wall conditions, and how much soft decking we find after tear-off. We give you a written price before any work starts, and we never change it at the door. Call (945) 303-9821 to schedule a free estimate.

FAQs About Roofing Company in Commerce
Ponding returns because the original low-slope roof was built near flat, and patching the membrane without correcting the drainage slope just moves the water to the next low spot. On Commerce’s post-WWII bungalows, the roof framing often settled over decades, creating shallow basins that hold water after a Santa Ana rain. The fix is a tear-off down to the decking, adding tapered insulation or a drainage plane to create positive slope, then laying a new membrane. A patch on a ponding roof will fail again, usually within a season. Call (945) 303-9821 for a free estimate on a proper slope correction.
A “square” is 100 square feet of roof area, and it’s the unit roofers use to price both materials and labor. When a Commerce quote says $500 per square, that means $500 for every 100 square feet of roof surface, not the home’s floor plan. A 1,200-square-foot bungalow often has 1,400 to 1,800 square feet of actual roof surface once you account for overhangs, low-slope sections, and attached garage roofs. Ask the roofer to state the total squares clearly on the written estimate, and we do exactly that on every Commerce job.
Party-wall protocol matters more in Commerce than almost anywhere else in the LA Basin because the residential bungalows near the city center sit close together, many sharing walls or walls just inches apart. Before we touch shared flashing, we photograph the existing condition of the neighbor’s side, document every penetration and tie-in, and notify the neighbor in writing. During tear-off we protect the shared wall so it’s never exposed to water, and after the new flashing goes in, we walk the neighbor’s side and verify the transition is sealed. We’ve done this on tight blocks off Washington Boulevard and Slauson Avenue, and it prevents the disputes that kill a roofing job. Call (945) 303-9821 if you have a party wall involved and want a written plan before work starts.
Yes. We plan every Commerce job around the city’s work-hour ordinances and the parking constraints on narrow residential streets. On lots where a full-size dumpster would block a neighbor’s access, we rent a spot or use a smaller container staged off the shared approach. Materials come in two small drops instead of one large delivery, and we hand-carry squares to the rear of the property. We also run a magnet sweep of adjacent driveways at the end of every day so no roofing nails end up in a neighbor’s tire. The access constraints are priced into your written estimate up front, so there are no surprises when the crew arrives.
Metal makes strong sense on many Commerce homes, especially the low-slope bungalows and ranch homes that get hammered by inland heat every summer. A standing-seam metal roof reflects heat instead of absorbing it, handles Santa Ana wind uplift on low slopes, and outlasts membrane systems by decades. On a 1950s ranch near the Commerce city center, we’ve installed metal roofs that shed water efficiently even at slopes under 3:12. The cost runs $15 to $28 per square foot installed, and we handle the drainage corrections so water never ponds at the rear wall again. Metal is not just for the warehouse campuses. Call (945) 303-9821 and we’ll tell you if your specific home is a good candidate.
