Fast, Reliable Roof Replacement Across Commerce
Roof replacement in Commerce usually runs $8,500 – $16,400 for a typical post-war tract home, and flat commercial roofs often land between $6.50 and $12.00 per square foot depending on the membrane system. We serve every address in the 90101 ZIP, from the residential streets off Eastern Avenue to the warehouses and freight buildings along the 710 corridor. Seacrest Roofing has worked in Commerce for years, and we know what the heat and industrial sun do to roofs here. If you need a straight answer about whether to repair or replace, call (855) 597-2817 and we’ll tell you honestly.
Why Seacrest Roofing Is Commerce’s Preferred Roof Replacement Company
Commerce is a small city, roughly three square miles, and most of its buildings sit under the same intense sun and smog that cook roofing materials year after year. Our Roof Replacement team has torn off enough old BUR and modified-bitumen roofs near Bandini Boulevard and the rail yards to know exactly what hides underneath. Commerce customers call us because we don’t push one shingle brand and we don’t sell a tear-off before confirming the decking actually needs it.
Noel Chambers runs our crews with a simple rule: open the roof, show the homeowner what’s there, and price the fix before touching anything else. Homeowners in Commerce who’ve hired us mention the same thing in reviews – the estimate didn’t change once work started, and someone walked them through every line item. We stock materials from seven manufacturers, so when a Commerce home needs architectural shingles to match a specific HOA color palette or a flat commercial roof needs a GAF modified-bitumen system, the material is already available, not backordered.
Response time to Commerce from our Downey yard runs about 25 to 40 minutes in normal traffic. For a roof that’s actively leaking into a warehouse or a bedroom, that matters. We also schedule around Commerce’s industrial clients differently than we do residential ones – freight hours, loading dock access, and tenant equipment all affect when we can stage material and run tear-off.
Styles & brands we work with
Reroofing in Commerce
Reroofing in Commerce means removing the existing roof surface and replacing it with new material, and on the older post-war homes near Veterans Park and Rosewood Park, that often reveals conditions the original bid never accounted for. Homeowners call us when shingles are curling, granules are collecting in gutters, or a roof has passed the 20-year mark. On a typical 1,200-square-foot Commerce home, reroofing with architectural shingles runs $9,800 – $14,600, including tear-off, underlayment, and standard flashing. If the roof is steep or the decking needs replacing, the number moves toward the top of that range.
What We Find Under Old Commerce Roofs
When we strip layers off a Commerce home built in the 1950s, we commonly find the original underlayment has turned to dust, the decking around plumbing vents is water-stained, and the framing near chimneys has settled or cracked. This is exactly what the editorial lens for this page describes – outdated materials and hidden structural problems that only appear once the roof is open. Seacrest addresses this by writing allowances into the contract before demolition starts, so you know what a worst-case deck replacement costs before we find it.
Written Approval, No Surprises
Noel’s policy is simple: if we open a Commerce roof and find rotted plywood or failed flashing, we stop, photograph it, and show you the exact line-item cost before we proceed. You approve it in writing. No one gets a change order for “unforeseen conditions” that should have been foreseeable. This is how a Commerce roof replacement stays on budget, and it’s why our customers refer us to neighbors on the same block.
Flat Roof Replacement in Commerce
Flat roof replacement in Commerce is a different trade from residential shingle work, and most of the flat roofs here sit on commercial and industrial buildings, not houses. These roofs fail from UV degradation and heat aging far more than from rain. The sun bakes modified-bitumen and built-up roofing membranes until they blister and alligator, especially around rooftop HVAC curbs, plumbing vents, and electrical penetrations. A typical flat roof replacement in Commerce runs $6.50 – $12.00 per square foot installed, with the lower end for a basic recover and the upper end for a full tear-off with new insulation and high-performance membrane.
Commercial Roofing in the 90101
On a flat industrial roof near the 710/5 interchange, the failure you’ll see first is blistering and surface cracking around penetrations, not a leak. We’ve responded to Commerce warehouse owners who thought they had a small repair and found the entire membrane had lost its flexibility to heat. Seacrest handles the logistics of working around freight operations – staging material away from loading bays, managing tear-off debris around tenant equipment, and scheduling work in phases so the business keeps running.
The Bandini Boulevard Job
We tore off a failed modified-bitumen roof on a 12,000-square-foot trucking warehouse off Bandini Boulevard, and the decking around three HVAC curbs was so heat-aged it crumbled underfoot, while the existing flashing had pulled loose at every penetration. We replaced the rotten plywood, installed new GAF modified-bitumen membranes with reinforced flashing at each curb, and added a reflective coating to cut UV degradation. The client now schedules annual inspections focused on those penetrations instead of waiting for a leak.
Trusted Brands We Service in Commerce
Seacrest installs GAF, CertainTeed, and Owens Corning shingle systems, along with IKO, Atlas, Tamko, and Boral. We keep local stock of the most common architectural shingle lines for Commerce roof replacements, so a full reroof doesn’t stall waiting on a distributor. If your Commerce building has a specific warranty requirement or an HOA color spec, we can match the manufacturer and product line that fits, not just the one we happen to carry. Seven brands, one honest recommendation.

AfterCommon Roof Replacement Problems We See in Commerce Homes
- UV-baked flat membranes: On the commercial and industrial buildings near the 710 and 5 freeways, summer heat and smog-driven UV cook old modified-bitumen and BUR surfaces until they blister and crack, especially around rooftop HVAC curbs. These roofs need replacement long before a rain leak appears.
- Hidden framing damage on post-war tract homes: Opening up a 1950s Commerce roof often exposes undersized rafters, water-stained decking, and failed underlayment that was buried under two or three layers of old roofing. A low bid that doesn’t include a decking allowance will balloon once this is uncovered.
- Failed flashing at penetrations: Plumbing vents, furnace flues, and skylights on older Commerce homes frequently have original sheet-metal flashing that has corroded or pulled loose. We replace every penetration flashing during a roof replacement, not just the shingles around them.
- Inadequate ventilation: Many Commerce tract homes were built with minimal ridge or soffit venting. When we reroof, code requires correcting this, which adds cost but extends the life of the new shingles significantly in this hot climate.
Pricing for Roof Replacement in Commerce, CA
For residential roof replacement in Commerce, expect $8,500 – $16,400 for a standard post-war tract home depending on square footage, shingle grade, and how much decking needs replacing. Architectural shingle roofs on a 1,200 – 1,600 square foot home typically land between $10,000 and $14,000. Flat commercial roofs run $6.50 – $12.00 per square foot. What moves the price is what’s underneath – rotted decking, failed underlayment, and code-required upgrades like drip edge and ice-and-water shield. We write allowances for these items into every Commerce quote so the final number doesn’t change without your written approval. Call (855) 597-2817 for a free, line-item estimate.

FAQs About Roof Replacement in Commerce
Commerce sits in a warm, dry part of southeast LA County with intense summer sun, heavy smog, and very little rainfall. The UV radiation and heat age flat membranes like modified-bitumen and built-up roofing until they blister, crack, and lose flexibility, especially around rooftop HVAC curbs, vents, and other penetrations. Rain is a minor factor here compared to UV, so a Commerce flat roof often needs replacement due to surface damage and brittleness before any leak appears. Call us at (855) 597-2817 and we’ll inspect the membrane condition directly.
On 1950s and 1960s tract homes in Commerce, we commonly find rotted decking around vents and chimneys, failed underlayment that’s turned brittle or powdery, undersized rafter framing, and outdated or damaged flashing. Some homes also have old knob-and-tube wiring or improperly vented attic spaces that only become visible once the roof is open. We build allowances into the quote for these items so you know the cost before we uncover them. Call (855) 597-2817 for a full inspection before you commit to a roof replacement.
Yes. When we pull a permit for a roof replacement in Commerce, current building code applies to the new work. That typically means adding drip edge, ice-and-water shield at the eaves, proper ridge or soffit ventilation, and sometimes upgraded nailing patterns. A low bid that ignores these requirements will come back with change orders once inspection happens. We include all code-required items in our Commerce quotes up front. Call (855) 597-2817 for an estimate that’s actually complete.
Compare the line items, not just the total. A Commerce roof bid should specify the shingle or membrane brand and model, the underlayment type, the number of decking sheets included as an allowance, flashing replacement scope, ventilation upgrades, and permit fees. If a bid doesn’t list these, the contractor is either cutting corners or planning change orders. Seacrest provides a written, line-item quote for every Commerce roof replacement, and Noel Chambers reviews it with you before you sign. Call (855) 597-2817 to get one for your building.
Architectural shingles from GAF, CertainTeed, and Owens Corning can achieve wind ratings of 110 – 130 mph when installed with the manufacturer’s required nailing pattern and a properly sealed underlayment. Commerce sees occasional Santa Ana wind events, so we install to the higher rating when the roof’s geometry and decking support it. Ask us which shingle line fits your budget and wind exposure. Call (855) 597-2817 and we’ll walk through the options.
