Westmont is a different animal than most of Los Angeles, and not every roofing company gets that. You live in an unincorporated pocket of LA County, the housing stock dates back to the late 1940s and 1950s, and the permitting process runs through the County, not LADBS. We know what that means for your roof because we deal with it here constantly. Tom Barrett founded Roofing company Barrett & Sons Construction in 1998, and the crews who show up on your street are his sons and their teams, not strangers from out of the area.
Why Barrett & Sons Construction Is Westmont’s Preferred Roofing Company
Westmont homeowners keep our number for the same reason your neighbor keeps a good mechanic on speed dial. We answer the phone. A live person picks up 24 hours a day, 7 days a week, not a voicemail box in another state. When a Westmont customer calls about a roof leak off Normandie Avenue or a re-roof near the 105, they get a direct answer about who’s coming out and when.
Tom Barrett publishes his name, address, and license number. You can look it up before you sign a single page. That’s on purpose. The homeowners we serve in Westmont are often in their 50s, 60s, and 70s, and a lot of them have been burned by a national outfit that quoted one price on the phone and handed them a different bill at the door. We don’t work that way. Every scope of work, every allowance, every change order goes into writing before the nail gun comes out. No surprise invoices at the end.
Our 90-Day Done Right Promise is written on every contract, not buried in fine print. If it’s not done right, one call brings Tom back. No argument. No runaround. That’s the whole point of hiring a name-on-the-truck company.
Our Roofing Services in Westmont
Roof Repair
Roof repair in Westmont runs $400-$1,800 depending on what we find once we open the deck. Most of the homes near 90047 were built between the late 1940s and early 1960s, and original framing doesn’t always match what’s sitting on top of it. Leaks around valleys and pitch changes are common, especially where an old porch or addition tied into the original roof line. We inspect first, then write the scope. If the repair expands, you approve a written change order before we proceed.

Roof Leak Repair
Leaks in Westmont don’t always come from where the water shows up. Expansive clay soils under the slab heave and settle through the long dry summers and winter rains, and that movement can crack fascia, lift roof edges, and break the seal at the eave before the roof membrane itself fails. We trace the leak to its actual source, which on a 90047 bungalow usually means getting into the attic and looking at the deck, not just slapping sealant on a visible water stain.

Roof Replacement & Installation
Full roof replacement in Westmont runs $8,000-$20,000. That range reflects what we find on older 1950s homes, including sheathing that needs replacement, rafter reinforcement the County may require, and the removal of multiple layers of old roofing. Because Westmont is unincorporated, the permit is issued by LA County Public Works, not LADBS. We pull the permit, coordinate the inspections, and make sure the inspector signs off before we clean the driveway.

Metal Roofing
Metal roofing on a Westmont home is a major upgrade, typically $15,000-$40,000. Standing seam metal Roofing handles the South LA heat well and sheds water fast during winter storms. But here’s the thing: original 1950s roof decks often don’t meet modern structural standards for metal roof weight. County plan check reviews the existing framing before a permit is issued, and we handle that review as part of our scope, not as a surprise mid-job.

Trusted Brands We Service in Westmont
We install GAF and CertainTeed roofing systems because these are brands you can look up, not mystery materials off the back of a van. On the hardscape and paver side, we carry Techo-Bloc and Cambridge Pavers, which matters when a roof project also involves drainage or gutter runs that tie into patios and walkways. We keep common parts and materials stocked for Westmont jobs, so a repair doesn’t stall waiting for a supplier across town.
Common Roofing Problems We See in Westmont Homes
These are the failure modes that repeat across this neighborhood, year after year:
- Original 1950s roof decks failing under modern weight: Tile and standing seam metal are heavier than the old composition shingles these homes were framed for. County plan check reviews the existing framing before issuing a permit, which means a re-roof can turn into a structural correction.
- Leaks at transitions from unpermitted additions: Decades of additions and garage conversions created valleys and pitch changes that leak where the new roof meets the old. Correcting those transitions often triggers a County compliance review that out-of-area roofers don’t expect or know how to handle.
- Clay soil movement cracking the eave line: The expansive clay under Westmont slabs heaves and settles with the seasons. That movement can crack fascia boards, lift roof edges, and break the seal at the eave before the roof covering itself ever fails.
- Failed waterproofing around old flashing: Flashing from the 1950s wasn’t built for 70 years of exposure. Roof leaks here are often rusted, separated, or missing flashing at the chimney, skylight, or plumbing vent.

A Westmont Roof Permit Is Not a City of LA Permit
This is the single most important thing to understand about any roofing project in Westmont, and most roofing companies never mention it until the job stalls. Westmont is an unincorporated community governed by Los Angeles County, not the City of Los Angeles. Every construction permit, inspection, and code enforcement action runs through the LA County Department of Public Works, not LADBS. That means a roofer who only knows the City of LA’s portal, fee schedule, and inspector workflow will hit a wall on your re-roof, and you’ll be the one waiting while they figure it out.
We figured it out a long time ago. The permit inspector works for you, not for me, and that’s why I like him. When a County inspector walks your roof, they’re checking the existing framing before they’ll sign off on modern tile or standing seam weight. That’s not a nuisance. It’s the difference between a roof that outlasts the next decade and one that sags in five years.
On a 1952 stucco bungalow off Westmont Drive, our crew opened a roof that had three layers of old composition shingles over skip sheathing. The County inspector flagged the undersized 2×4 rafters before we could sign off, so we sistered new 2x6s and added a continuous ridge vent, turning a one-day tear-off into a two-day structural correction, all documented in a change order. That’s how it’s supposed to go. The scope changed, you saw it in writing, you approved it, we did the work, the inspection passed.
If you’re planning to legalize a roof over an unpermitted ADU or garage conversion, the project lands in LA County’s unincorporated plan check queue, not the City’s. Backyard units are extremely common on small R-2 lots in Westmont, and bringing one into compliance means unfamiliar forms, setback tables, and inspection workflows. We handle that paperwork as a standard part of the job. Ask anyone on your street, or look up the license number yourself.

FAQs - Roofing in Westmont
Yes. Because Westmont is unincorporated LA County, roof replacement permits are issued and inspected by LA County Public Works, not LADBS. A roof repair that doesn’t change the structural assembly may not need a permit, but any re-roof, structural repair, or material change that adds weight to the existing framing almost certainly will. We pull the permit, coordinate the inspection, and make sure everything is signed before we finish. Call (877) 610-1318 and we’ll tell you exactly what your project requires.
We’ve seen County roof permits for Westmont clear in as little as a few days for a simple re-roof, and several weeks if the project involves legalizing an unpermitted addition or a structural correction. The County’s unincorporated plan check queue moves at its own pace, and it differs from LADBS timelines. What matters is that we know how to file correctly the first time, which keeps your job from sitting in a queue waiting for a resubmission. Call (877) 610-1318 for a realistic timeline on your specific roof.
Because County plan check looks at the existing framing before it issues a permit, and original 1950s roof decks were often framed with 2×4 rafters that don’t meet current standards for the weight of modern tile or standing seam metal. Sistering new 2x6s alongside the old rafters is a common correction on Westmont bungalows. It adds a day or two and some cost, but it prevents sags and failures you’d be paying for later. We document it in a written change order before the work happens. Call (877) 610-1318 to get a structural assessment before you commit to tile.
Indirectly, yes. The expansive clay under Westmont slabs heaves and settles with seasonal moisture changes, and that movement can crack fascia, lift roof edges, and break the seal at the eave where the roof meets the wall. The leak may show up as water at the ceiling, but the real problem is movement at the roofline. We look for that pattern on every Westmont leak call. Call (877) 610-1318 and we’ll trace it to the actual source.
Yes. Unpermitted rear-unit conversions are extremely common on small R-2 lots in Westmont, and when owners want to bring them into compliance under California’s ADU amnesty rules, the project lands in LA County’s unincorporated plan check queue. That means County-specific forms, setback tables, and inspection workflows. We handle this as standard scope, not an exception. If the roof over your garage conversion or ADU needs to be brought up to code as part of a legalization, that’s work we do regularly here. Call (877) 610-1318 for a free estimate and a straight answer.
