Roofers in Commerce, CA
Roofing in Commerce, CA starts with a question most cities never ask: is this a roof over a home, or a roof over a working building? We handle both. Most of what we inspect here is flat or low-slope, aged under decades of sun, and tied to the city’s freight and manufacturing rhythm rather than a quiet cul-de-sac. Whether you need a Roof Inspection on a 1950s tract home or a modified-bitumen assessment on a warehouse near the 710, you can reach us at (855) 597-2817.
Why Commerce Homes Are Different
Commerce sits in a tight, roughly 3-square-mile pocket between the 5 and the 710 in southeast LA County. That geography shapes every roofing decision here. The city mixes older post-war tract homes on small lots with a much larger share of flat and low-slope industrial buildings: warehouses, trucking sheds, light-manufacturing structures near the rail yards and freeway corridors. On the residential side, many roofs are original or second-generation, built when Commerce was still filling in after the war. On the commercial side, you see decades-old built-up roofs and modified-bitumen membranes that have been patched, re-patched, and left to bake.
The climate does the real damage. Warm, dry, and relentlessly sunny, this corner of LA County rarely tests a roof with rain. What it tests is UV resistance. Summer heat and smog-driven exposure cook flat membranes until they blister and alligator, especially around rooftop HVAC curbs and pipe penetrations. When winter storms do arrive, the callbacks are rarely about missing shingles. They are about ponding water that sat too long on a low-slope section and found the one weak seam. Any roofer working Commerce needs to read heat aging as fluently as they read a shingle.
Styles & brands we work with
Our Main Commerce Services
Two services drive most of the calls we get from Commerce homeowners and building owners. Each one has its own dedicated page for the city, but here is the short version of what each involves.
Roof Repair in Commerce
Repair work in Commerce tends to fall into two buckets. On homes, it is often cracked or slipped shingles, failed flashing around vents and chimneys, or dry-rot sections where a small leak went unnoticed for a season. On flat roofs, it is membrane splits, open seams, and failed patches around curbs and drains. We treat repair as a primary service, not a step toward selling a new roof. If a targeted fix restores the roof’s integrity, that is the honest answer we give. If the decking or the membrane has reached its end, we will tell you that too, with numbers in front of you. Learn more about Roof Repair in Commerce.
Roof Replacement in Commerce
Replacement in Commerce means something different depending on the structure. A pitched residential roof might move from three-tab to architectural shingles, with a full tear-off and new underlayment. A flat commercial roof might move from an exhausted built-up system to a modern modified-bitumen or single-ply assembly, with new flashing details at every penetration. Because we carry seven shingle manufacturers, including GAF, CertainTeed, and Owens Corning, the material conversation starts with what fits your roof and your budget, not what we happen to stock in one brand.

Roof Inspection in Commerce
A roof inspection in Commerce is most useful when it diagnoses before it sells. On the flat industrial roofs near the 710 and 5 interchange, we are less concerned with rain leaks than with what heat has done to the membrane: blistered modified-bitumen, alligatored BUR surfaces, failing seals around rooftop equipment. On the post-war tract homes, the inspection is about age, flashing condition, and whether the original roof structure has decades left or a handful of seasons. Seacrest Roofing has served Commerce since 2018, and our Roof Inspection is a standalone service. You get a professional assessment without any obligation to buy anything afterward.
Roof Inspection Services
Signs you need it
You should schedule a roof inspection in Commerce if your roof is past its 15th year, if you see daylight in the attic, or if water stains have begun to spread across a ceiling after one of the region’s rare winter storms.
What it costs in Commerce
A standard roof inspection in Commerce runs between $195 and $350, depending on roof size, access, and whether it is a residential pitched roof or a flat commercial membrane.
How we do it
We walk the full roof surface and perimeter, check flashing, seams, penetrations, and drainage paths, then document what we find with photos and a plain-language written summary you can keep.
Hail Damage Roof
Signs you need it
After any storm that brought hail to southeast LA County, check for pockmarks or soft indents on shingle granules, dents in metal flashing, and granule buildup in gutters or downspouts.
What it costs in Commerce
A hail-specific roof assessment in Commerce is typically folded into a standard inspection at $195 to $350, unless insurance documentation work pushes it into the $350 to $550 range.
How we do it
We identify hail signature patterns by roof slope and material, photograph each impacted area, and give you a straight assessment of whether what we see is cosmetic or structural.
Roof Estimate
Signs you need it
You need a roof estimate in Commerce when you are comparing repair versus replacement, or when an inspection has revealed damage and you want line-item numbers before deciding how to proceed.
What it costs in Commerce
Upfront roof estimates in Commerce are free for most homes, with repair estimates and replacement estimates separated by line item so you can see exactly where the money goes.
How we do it
We measure the roof, confirm the existing material and deck condition, then build a written estimate with material choices across multiple brands and a fixed number for the work.
Free Roof Inspection

A free roof inspection in Commerce is worth scheduling when you are on the fence about whether your roof has 3 years left or 10, and you want a professional read without spending money to get it.
What it costs in Commerce
Free roof inspections in Commerce are available for most residential roofs, with no purchase required and no obligation to move forward with any repair or replacement.
How we do it
We perform the same surface walk, flashing check, and drainage review we do on paid inspections, then walk you through what matters, what can wait, and what cannot.
Roof Inspection Companies
Signs you need it
You are comparing roof inspection companies in Commerce when you want a second opinion on a quote you have already received, or when you want an inspection from a contractor that does not push one shingle brand.
What it costs in Commerce
Roof inspection companies in Commerce generally charge $195 to $350 for a residential inspection and $350 to $550 for larger flat or commercial roof assessments.
How we do it
We bring a material-neutral eye to every inspection in Commerce, which means we diagnose the condition first and only then talk about which product, if any, fits the fix.

Do I need a roof inspection before buying a home in Commerce?
Yes, especially in Commerce, where home age and roof type vary block by block. A pre-purchase inspection tells you whether you are buying a roof with usable life left or a hidden $20,000 line item. The inspection cost is small compared to finding out after closing.
Can you inspect a flat commercial roof in Commerce?
We can. Flat roof inspections in Commerce focus on membrane condition, seam integrity, ponding patterns, and every penetration where equipment meets roof. We document alligatoring, blistering, and open seams, then give you a written report with repair priorities ranked.

Because we carry multiple brands rather than one, the recommendation you get is matched to your roof, your HOA constraints if any, and your budget tier.

On residential jobs, roof complexity and sheer age are the bigger drivers. When we quote a price in Commerce, it is the price. No change orders halfway through, no surprise line items at the end.

What Commerce Customers Say
"Valley had been done without proper underlayment and was leaking. Redone correctly, and he explained exactly what had been wrong so I could understand it."
— Kurt Sutton"Added a ridge vent and cleared the blocked soffit vents. Attic temperature in the summer dropped noticeably and the upstairs is livable now."
— Sofia Reyes"Storm took part of the ridge off at night. They tarped it the same evening so the rain didn't get in, and did the real repair the following week."
