Fast, Reliable Roofing Across Westmont
If you own a home in Westmont, you already know the drill: the roof that looked fine in August starts showing its age the first week the winter rains arrive. A small leak near the chimney or a lifted shingle on the west-facing slope is all it takes before you’re checking the ceiling for water stains every time it drizzles. Barrett & Sons Construction has been climbing onto roofs across the 90047 zip code long enough to know exactly how Westmont homes fail, and how to fix them right the first time. If you’ve spotted a problem, call us at (877) 610-1318 and we’ll come take a look. The estimate is free, and nobody pays a trip charge inside the County.
Why Barrett & Sons Construction Is Westmont’s Preferred Roofing Company
Westmont runs on word of mouth. We know that because most of the calls we get from the neighborhood start with “my neighbor on 108th said you did their roof.” That’s how it should work. Tom Barrett started this company in 1998, and he’s never hidden behind a brand name or a call center. His name, his address, and his license number are published for anyone to look up before signing anything. The crew that shows up in Westmont is his crew, supervised by his sons, not a subcontracted crew picked up for the week.
When a Westmont homeowner calls us about a leak, we get there quickly. But more important than how fast we arrive is what we do once we’re on the roof: we look at the whole system, not just the visible damage. In Westmont, that matters because the housing stock is old enough that one problem usually points to three others. We’d rather tell you the truth up front than patch a symptom and charge you for it again in six months. That’s the difference between a roofing company that wants a check and one that wants to be the roofer you call for the next twenty years.
Our Roofing Services in Westmont
Roof Repair
Most Westmont roofs are 60 to 70 years old if they haven’t been replaced, and the first things to go are the flashings around pipes, chimneys, and the unpermitted additions that are so common in this neighborhood. We repair leaks at the source, not the stain on the ceiling. A typical Roofing repair in Westmont runs $400 to $1,800, and we’ll show you exactly what we found before we touch anything. Written scope, written price, no surprises.

Roof Replacement & Installation
When a roof in Westmont is done, it’s usually done all at once: original 1950s underlayment, decades of patch jobs, and framing that’s been wet more times than anyone remembers. A full replacement here typically lands between $8,000 and $20,000 depending on size, pitch, and decking condition. We use GAF and CertainTeed products because we can stand behind them, and because your neighbors can look them up. Every replacement we do includes permits pulled through LA County and inspections signed before we call it finished.

Metal Roofing
Metal roofing is the one material that laughs at the Westmont afternoon sun. It reflects heat, lasts decades longer than asphalt, and stands up to the Santa Ana winds that hit the South LA basin every fall. A standing seam metal roof in Westmont runs $15,000 to $40,000. It’s not the cheapest option, but if you’re staying in the house, it’s often the last roof you’ll pay for. We install it the same way we install everything else: with a written change order before any change, and a 90-Day Done Right Promise on the finished job.

Tile Roofing
Tile is heavier and more expensive to repair, but plenty of Westmont owners inherited barrel tile from a previous generation and want to keep it. Tile roof repair here runs $600 to $2,500, and the most common call we get is cracked or slipped tiles after a hard wind. The inspection is just as important as the repair because broken tile isn’t always visible from the ground, and a hidden crack is a leak waiting for the next rain. We’ll walk the whole roof, mark every problem spot, and give you a written list of what actually needs work.

Trusted Brands We Service in Westmont
We’re not interested in putting mystery-brand materials on your roof and crossing our fingers. When we install GAF or CertainTeed products, you get a manufacturer’s warranty worth the paper it’s printed on plus our own written workmanship promise. If you’ve got an existing roof with specific components, we’ll source the right match for the material that’s already up there. For the flatwork and hardscape side of Westmont properties, we also work with Cambridge Pavers and Techo-Bloc when a project calls for them, and we also handle Windows & Doors in Westmont when roof damage means it’s time to replace the windows underneath. And if the winds took down a section of fence along with your shingles, our Fence Installation in Westmont crew can handle that too.
Common Roofing Problems We See in Westmont Homes
- Failed flashings around unpermitted additions. So many Westmont lots have a rear addition or converted garage from decades ago, and the roof junctions on those structures were rarely flashed correctly. Water finds those seams first.
- Brittle, sun-baked asphalt shingles. The long rainless stretch from April to November cooks roofs up here. We see shingles that crumble in your hand by the time they’re 15 years old, even if they were rated for 25.
- Wind-lifted shingles on east-west slopes. Santa Ana gusts come down through the South LA basin hard, and the leading edges on the exposed slopes take the worst of it. Lifted tabs are an open door for the next rain.
- Clogged, undersized gutters. A lot of Westmont homes still have original 4-inch gutters, and when they clog with leaves from mature trees, overflow pours straight down the fascia and behind the stucco. We see the same repair pattern every winter.
Pricing for Roofing in Westmont, CA
Let’s talk real numbers so you know what to expect before you pick up the phone. A roof repair in Westmont runs $400 to $1,800 depending on the number of penetration points and whether decking needs replacement. A full roof replacement on a typical small-lot bungalow runs $8,000 to $20,000. If you want metal, budget $15,000 to $40,000. Tile roof repair runs $600 to $2,500. What moves the number is access, pitch, decking condition, and whether the project triggers a compliance review from the LA County Department of Public Works, which absolutely happens when there’s an unpermitted addition involved. We’ll give you a written, line-by-line estimate before you commit to anything. Call (877) 610-1318 and we’ll schedule the free estimate. Also, remember: $40 off any repair over $200, and a permanent 10% senior and veteran discount on every job.

Yes. Westmont is unincorporated LA County, so every eligible roof replacement is permitted through LA County Department of Public Works, not LADBS.

Not significantly. The market pricing for roofing in Westmont is right in line with Inglewood, West Athens, and Lennox: $8,000 to $20,000 for a standard asphalt replacement.
