Roofers in Commerce, CA
Roof inspection in Commerce usually answers one question: is this roof done, or does it have another five years? The answer matters more here than in most cities because Commerce carries an unusually heavy load of flat and low-slope roofing on post-WWII industrial buildings and small tract homes, all of it baking under intense Southern California sun. We inspect first and recommend second, because nobody in Commerce should pay for a full replacement when a targeted repair keeps the roof watertight. Call (833) 467-4901 to schedule a roof inspection.
Why Commerce Homes Are Different
Commerce sits in a bowl of freeway exhaust and sun, ringed by the I-5, I-710, and the 60, just southeast of downtown LA. The city never sprawled the way its neighbors did; it stayed compact and industrial, which means most of the roofable square footage in Commerce belongs to warehouses, light-manufacturing buildings, and low-rise commercial structures rather than steep residential roofs. The housing stock that does exist is largely tract-style single-family homes on small lots, built during the post-WWII boom, and many of those roofs are original or carrying one overlay on decks that are now sixty or seventy years old.
For roofing, that changes the work. Flat and modified-bitumen membranes dominate here, and the failure pattern our techs see repeatedly is standing water at clogged scuppers and drains after a winter storm. Ponding quietly rots the deck long before the interior shows a stain. Intense UV and summer heat bake flat roofs, drying out built-up membranes until they crack and alligator. Commerce roofs fail from sun exposure and drainage problems far more often than from wind or hail. A roof inspection here has to read the drains, the scuppers, and the low spots as carefully as it reads the membrane itself.
Styles & brands we work with
Our Main Commerce Services
The two calls we get most from Commerce property owners are repair and replacement, and the honest answer is often not the one the caller expects. These are the two service paths, each with its own dedicated Commerce page.
Roof Repair in Commerce
Most flat-roof failures in Commerce start small: a cracked membrane around a penetration, a pooled area that finally soaked through, a scupper that backed up during the season’s first real rain. Repair work here means matching the existing system correctly, whether it’s built-up roofing, modified bitumen, or a coating, so the patch doesn’t fail at the seam a year later. We carry materials from multiple manufacturers so the repair product matches the roof that’s already on the building. See Roof Repair in Commerce for the full breakdown.
Roof Replacement in Commerce
When a Commerce roof has reached the end of its serviceable life, replacement means tearing down to deck, correcting any rotted sheathing, and rebuilding the system so it drains properly in this climate. On flat commercial roofs, that means slope correction, new drain assemblies, and a membrane rated for relentless UV. On the residential side, it means an honest conversation about which shingle or low-slope product fits the house and the budget. Seven brands, one contractor, and no single-vendor lock-in. See Roof Replacement in Commerce for details.

Roof Inspection in Commerce
A roof inspection in Commerce typically costs $150 to $600 depending on building size and roof type, and it is the fastest way to know whether a roof needs a repair or a replacement without guessing. In a city full of aging flat roofs on post-WWII industrial buildings and small houses, the inspection is diagnostic work: we read membrane condition, drainage patterns, and deck health before any repair or replacement recommendation. We offer it as a standalone service, not as a sales tool, which means the report you get from our Roof Inspection team tells you what the roof actually needs.
Roof Inspection Services
Full roof condition assessments for Commerce homes and commercial buildings, covering membrane, flashing, drainage, and deck structure.
Signs you need it
You see water staining on a ceiling, daylight through a roof deck, or standing water on a flat roof 48 hours after rain.
What it costs in Commerce
Expect $150 to $350 depending on roof size and accessibility.
How we do it
Walk the entire roof surface, document membrane cracks, blisters, and ponding, inspect all penetrations and flashings, test drains and scuppers, then write a condition report with photos.
Hail Damage Roof
Hail damage assessment for Commerce properties, checking membranes, shingles, and flashings for impact marks that lead to premature failure.

Recent hail was reported in the area, or you notice circular impact marks, exposed fiberglass, or knocked-loose granules on a shingle roof.
What it costs in Commerce
Figure $200 to $400 for a focused hail assessment with photo documentation.

Inspect all slopes for impact bruising, check soft metals and vents for denting, document findings for insurance claims, and recommend repairs based on actual damage.

Detailed written estimates for repair or replacement work, built from the inspection findings and your building’s actual conditions.

You already know the roof needs work and want a real line-item price before committing.

How long does a roof inspection take in Commerce?

Do I need to be home for a roof inspection?
No. We can inspect the exterior and roof surface without anyone present, and we’ll leave the written report at the door or email it the same day. For commercial buildings, we coordinate roof access with the property manager ahead of time.
Brands We Service in Commerce
We’re authorized to install roofing products from GAF, Atlas, Boral, and Tamko, among others. That matters in Commerce because flat and low-slope roofs need specific membrane systems, not whatever a single-brand contractor happens to stock. We keep common repair materials on hand locally and can usually source specialty products within a week. See our brands for the full portfolio.

Two things push Commerce roof pricing above the regional baseline. The first is square footage: industrial and warehouse roofs here run large, and material volume scales linearly. The second is drainage correction: many older Commerce roofs were built with inadequate slope, and a proper replacement usually includes re-sloping or adding interior drains. Every job is priced from a written, line-item estimate before we start, and the number we quote is the number you pay. No change orders on work we already inspected.
Neighborhoods We Serve in Commerce
Commerce is small enough that we cover the entire city from the 90101 ZIP code without splitting it into service zones. The residential pockets off of Telegraph Road and the streets near the Citadel Outlets see the same flat-roof issues as the warehouse rows along Bandini and Eastern. We know which blocks sit low and collect water, and we schedule inspections around your building’s access hours rather than the other way around.
- The Citadel and Telegraph Road area
- Bandini Boulevard industrial corridor
- East Washington Boulevard warehousing district
- Rosewood Park and the residential streets near the 710
- Commerce Way commercial stretch

FAQs About Roofers in Commerce
Yes. The city of Commerce requires building permits for roof replacements and most structural repairs, and we pull permits before work begins. Inspections are scheduled with the city after the roof is in place, and we don’t call the job done until the permit is signed off.
Inspections can typically be scheduled within a few business days. For repairs, we usually start within one to two weeks once the estimate is approved and materials are confirmed. Replacements depend on roof size and permit processing, which in Commerce generally adds one to two weeks.
We handle both, and in Commerce the commercial flat-roof work is the majority of what we see. We inspect, repair, and replace built-up roofs, modified-bitumen systems, and coated membranes on warehouses and light-manufacturing buildings, and we handle residential roofs with the same inspection-first process.
