We work as a roofing contractor in Westmont, CA, about 45 minutes (21 miles) from our base on Rosemead Blvd. Westmont is an unincorporated community of 33,913 people (2020) in South Los Angeles, centered on Vermont Ave just west of the Harbor Freeway.
The housing is dense and older: small single-family homes, duplexes, back houses and low apartment buildings packed onto narrow lots. Many properties have a pitched shingle roof on the front house and a flat roof on the rear unit, and most mail reads Los Angeles even though the City's building department has no say here.
Why the LADBS counter can't permit a Westmont roof
LADBS, the City of Los Angeles building department, has authority only inside city limits. Westmont is county territory, so roof permits and inspectors come from the county's Public Works Building & Safety office. Filing with the wrong office only sends an application back, which is why we check every parcel before we quote.
When a permit is required, we file it with the county and schedule the inspection. On rentals, we work out tenant notice and access with the owner before the crew arrives.
Roofing services for Westmont, CA properties
Flat Roofing
Rear units, additions and small apartment buildings here run on low-slope roofs that pond and split, and many have been patched over so often that the layers hide wet decking.
Roof Repair
Vents, chimneys and pitched-to-flat tie-ins cause most leaks on older Westmont homes, and a fast repair keeps a tenant's ceiling from turning into a drywall job.
Roof Replacement
Front houses often carry a second shingle layer over plank decking that needs a full tear-off, county permit and per-sheet pricing for any soft boards we find.
Rain Gutters
Short eaves and tight side yards on Westmont lots send overflow against stucco and neighbors' walls, so seamless gutters and downspouts belong in most reroof scopes.
Apartment & HOA Roofing
Small apartment buildings off Vermont and Normandie need roof work scheduled around tenants, with notice, access and staging agreed with the owner before crews arrive.
Roof Coatings
A coating suits a Westmont rear-unit or apartment roof only when core cuts show dry insulation and a sound deck; over a wet roof it hides the leak for a season.
Emergency Roof Tarping
When a tenant reports water during a storm, a battened tarp holds the unit dry until the county-permitted repair can be filed and scheduled in better weather.
Duplexes, back houses and flat roofs along Vermont Ave
- Front houses: older composition shingle, often a second layer over plank decking.
- Rear units and additions: low-slope rolled roofing or torch-down that ponds and splits at the seams.
- Small apartment buildings: flat roofs with parapets, scuppers and rooftop vents that need new flashing.
- Tight side yards: gutters and downspouts that overflow against walls and neighbors' fences.
Short eaves on these homes mean every clogged gutter dumps water against stucco and foundations. Gutter replacement often pays off alongside a reroof.
Normandie Avenue blocks, Washington Prep and the Vermont Vista line
Westmont packs 10,990 housing units (2020 census) into about 1.8 square miles, roughly 18,000 residents per square mile. At the 2010 census only 31.1% of homes were owner-occupied, so many of our calls here come from landlords and property managers rather than the people living under the roof.
The name likely comes from sitting west of Vermont Avenue. The community borders the City of LA's Vermont Vista neighborhood and lies just east of Inglewood, and blocks around Normandie Avenue and George Washington Preparatory High School mix front houses, rear units and small apartments. One street over can mean LADBS instead of the county, so the parcel check matters here.

Which roof services do Westmont property owners book?
Flat roof repair and replacement on rear units and small apartment buildings leads the list. Shingle tear-offs on front houses come next, followed by leak repairs at vents, chimneys and the joint between pitched and flat sections. Our guide to roof repairs on rental homes covers what landlords should plan for.
On flat roofs, the choice is usually between a new torch-down or TPO membrane and a coating over a roof that is still sound. We cut into suspect spots to check for wet insulation or soft decking before recommending either, because a coating over a wet roof only hides the problem for a season.
Scheduling, quotes and nearby South Bay areas
Westmont visits get slotted same-day or next-day when crews are free, grouped with jobs in West Athens, Inglewood, Lennox, Hawthorne and West Rancho Dominguez.
Each roof on the lot gets photographed and quoted on its own line, along with the county permit and any deck boards. That lets you fix the leaking rear unit now and schedule the front house later. Call (725) 745-8803 to set up a visit.

“We looked at a few roofing companies to get our roof replaced. One company took the time to explain the whole process in detail. Grant, their representative, brought samples to show us how the new roof would look and gave us different color options to choose from. He answered every question I had with a positive attitude. …”
“I worked with Tanner, and he stayed professional from start to finish. He was patient, easy to talk to, and flexible, and he made time around my busy schedule. When we got to the financing part, Brandon went the extra mile to help me look at every available option and explain the process clearly. …”
Roofing questions from Westmont
My Westmont address says Los Angeles. Which office issues my roof permit?
LA County Public Works Building & Safety. Westmont is unincorporated, so the City of Los Angeles does not permit work there despite the mailing address. We confirm the parcel in the assessor record and file with the county.
Can you reroof the front house and the rear unit at the same time?
Yes. We often do both in one project, using shingle on the pitched front roof and a low-slope membrane on the rear unit. The quote lists each roof separately, so you can also split them into two phases if that suits your budget or tenants better.
What do you do if a tenant reports a leak in a Westmont rental?
We arrange access with the owner, then find the entry point and either repair it or secure it with a tarp if the full fix needs a permit or better weather. You receive photos of the cause and a written quote you can share with your tenant or keep for your records.
