Fast, Reliable Roof Replacement Across Commerce
Roof replacement in Commerce typically runs $8,500 – $14,500 for a standard single-story stucco home, and most jobs take 3 – 5 working days once materials land and permits clear. If your roof is original to a 1950s or 60s build, or you’re seeing water stains at the garage tie-in or porch edge, you’re probably looking at a full replacement rather than another patch job. Our crews work Commerce every week, and we know the difference between a steep shingle tear-off in Downey and the low-slope assemblies that dominate your streets. Call (833) 589-5180 and we’ll schedule an inspection before we ever talk price.
Why Sunridge Roof Repair Is Commerce’s Preferred Roof Replacement Company
Commerce homeowners call us because we inspect before we recommend. That’s not a slogan, it’s the only way to give an honest number on a house where the roof has been hiding problems for sixty years. Ruben Ochoa runs our roofing-only operation, and every estimate that leaves our hands reflects a roof we’ve actually walked. Not a satellite photo, not a drive-by. A person on the roof looking at seams, flashing, and decking.
We’re roofing specialists, not a general contractor who happens to own a ladder. That focus matters in Commerce, where a big share of the work is low-slope and near-flat assemblies that demand different underlayment, different flashing details, and different ventilation than a steep pitch in Bell Gardens. Our Roof Replacement team handles the whole lifecycle: inspection first, then an honest repair-vs-replace conversation, then the work itself. You don’t have to hire three different companies to get from leak to new roof.
We work with seven manufacturers: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. That means your material recommendation comes from your roof’s pitch, your budget, and your exposure to Commerce’s summer sun, not from a supplier relationship we’re trying to protect. Premium or value tier, you get name-brand product with a real warranty behind it.

Asphalt Shingle Roof Replacement in Commerce
Asphalt Shingle Roof Replacement in Commerce is the most common residential job we do, but it rarely looks like the textbook tear-off. Most of the homes here have low-pitch main roofs and near-flat porch and garage sections, so shingle scope on the main field often pairs with a membrane or modified bitumen tie-in at the low-slope areas. On a typical 1,000 – 1,400 square foot Commerce home, an architectural shingle replacement runs $9,500 – $13,500 including tear-off, underlayment, flashing, and haul-away. If the decking underneath is soft, that number moves, and we’ll show you exactly why with photos before we spend a dollar of your money.
Architectural Shingle Options for Low-Slope Sections
Architectural shingles like GAF Timberline or CertainTeed Landmark give you a thicker, more dimensional look and hold up to UV better than three-tab. But on a Commerce roof where the pitch drops below 3:12 near the porch or garage, shingles stop being the right material. We’ll spec architectural shingles on the steeper field and match them with a compatible low-slope system at the transitions, so you’re not paying for a shingle warranty that’ll void itself in two summers.
What Gets Pulled Up on a Tear-Off
When we strip a Commerce roof that’s on its second covering, we almost always find something under it. Rusted flashing at the garage tie-in, soft decking at the scupper edge, or felt paper that’s turned to dust. We write a decking replacement allowance into every Commerce quote, priced per sheet, so when we open the roof and find rot, you already know what the fix costs. No mystery change orders.
New Roof Installation in Commerce
New Roof Installation in Commerce often means a full re-roof on an addition, a converted garage, or a new build on one of the remaining infill lots. For a standard new construction or major renovation scope, expect $12,000 – $18,000 depending on square footage and pitch. The advantage of new installation is a clean deck, full access to the framing, and the chance to get underlayment, flashing, and ventilation right the first time, no surprises hiding under old layers.
New Construction Sequencing With Your Framing Crew
If you’re building in Commerce, we coordinate directly with your framer. The roof deck goes down, we inspect it before anything gets covered, then underlayment, drip edge, and shingles go on in sequence. That inspection step is the difference between a roof that leaks in year three and one that outlasts the mortgage.
Flat and Low-Slope Installations on Garage Conversions
Commerce has a lot of detached garages and a growing number of ADU conversions. These structures typically call for flat or low-slope roofing, not shingles. We’ll install a torch-down or self-adhered modified bitumen system with proper crickets and scupper detailing, then tie it into the main house roof with metal flashing that actually laps the right direction. This is the detail that leaks on a lot of local conversions, and it’s the first thing we check.
Trusted Brands We Service in Commerce
We’re brand-agnostic, which means your Commerce roof gets the product that fits it, not the product we’re incentivized to push. For steep sections, we regularly install CertainTeed Landmark and Owens Corning Duration architectural shingles. For low-slope and flat areas, we lean on IKO and Atlas membrane systems with a proven track record in the Los Angeles Basin. Because we’re not tied to one distributor, we can pull material fast for Commerce jobs and match your existing roof color when you’re only replacing one elevation or a garage. You’ll see the brand name on the quote, not a vague “premium shingle” line item.

AfterCommon Roof Replacement Problems We See in Commerce Homes
- Second-covering tear-offs that reveal soft decking: Many Commerce homes from the 1950s and 60s still have their original wood shake or composition roof buried under a second layer. That second layer hides rot, failed underlayment, and decking that crumbles when you pull nails. We budget for it and show you photos before we proceed.
- Rusted flashing at detached garage tie-ins: The garage roof meets the house roof at a flashing detail that’s usually original to the house. Six decades of heat cycling and the occasional winter storm rust it through. It’s the single most common leak point we find on Commerce stucco homes.
- Low-slope porch and scupper rot: On compact streets west of the industrial core, the porch roof often slopes almost flat toward a scupper. When that scupper clogs or the edge flashing fails, water sits, decking softens, and the repair becomes a structural one. A proper replacement includes new decking, ice and water shield at the edge, and a drain path that actually moves water off the roof.
- Heat-stressed seams on near-flat assemblies: Commerce summers push roof surface temperatures over 140 degrees. On near-flat roofs, that thermal cycling opens seams and stresses penetrations around vents, pipes, and HVAC curbs. If your replacement skips proper seam treatment and upgraded flashing, you’ll re-roof again in a few summers.

FAQs About Roof Replacement in Commerce
Because your roof is hiding what it’s been hiding since the 1960s. Soft decking, rusted flashing, and failed underlayment only show up once the old layers come off. We handle this by writing a per-sheet decking allowance and a flashing contingency into every Commerce quote, so you know the unit price before we open anything. When we find rot, you get photos and a written change order before we touch it. Call (833) 589-5180 to get a quote that already accounts for what’s likely under there.
On the steeper sections of your roof, yes. On the near-flat porch, garage, or main field below about 3:12 pitch, shingles will fail because water moves too slowly across them. We’ll spec architectural shingles like CertainTeed Landmark on the sloped areas and pair them with a low-slope membrane system at the flat transitions, so the whole roof is watertight and each section carries a real manufacturer warranty. For an exact material match on your home, call (833) 589-5180.
Sometimes, yes. When we pull a re-roof permit on an older Commerce home, the inspector may require upgrades that weren’t code when the house was built, like added eave ventilation, stronger edge metal, or seismic clips if we expose the framing. A reputable contractor flags these before the inspection happens. We walk the roof before quoting so you know which upgrades are likely, and we write them into the estimate instead of springing them on you after the inspector leaves.
Put the line items side by side. Look for whether the decking allowance is written as a fixed per-sheet price, whether flashing replacement at the garage tie-in and porch scupper is included or listed as “as needed,” and whether the underlayment spec meets code for your roof’s pitch. Bids that look $2,000 cheaper often leave out the things that actually fail on Commerce roofs. We’ll give you a written, itemized quote you can compare line by line, and estimates are free at (833) 589-5180.
Commerce sits inland enough that wind isn’t the primary threat, but building code still calls for shingles rated to at least 110 mph uplift when installed with the manufacturer’s specified nail pattern. We install to that standard on every Commerce job, and the architectural shingles we use from GAF, CertainTeed, and Owens Corning carry ratings well above it. If you want a specific wind warranty documented, ask and we’ll put it in writing.
Key Takeaways for Commerce Homeowners:
- Most Commerce roofs are low-slope assemblies, not steep shingle tear-offs, so the scope and the materials differ from neighboring cities.
- The garage tie-in and low-slope porch are where these homes leak first, and they’re usually original to the 1950s or 60s build.
- We write per-sheet decking allowances and flashing contingencies into every quote, so surprises have a price before we open the roof.
- Brand choice is yours: GAF, CertainTeed, Owens Corning, IKO, Atlas, and more, matched to your roof and budget, not our supplier.
If your Commerce roof is showing its age, or if you’ve already had a patch fail at the garage tie-in or porch edge, the next step is a real inspection. Call (833) 589-5180 to schedule your free estimate. We’ll walk the roof, show you what we find, and give you a written number that covers the roof you actually have.
