Roof repair in East Los Angeles usually costs between $350 and $1,900 depending on what failed, and most jobs are finished in a single day.

If you’re seeing water stains on a ceiling or missing tile after a Santa Ana, call (743) 200-8347 and we’ll get a written price in your hands before any work starts.
Why Mercer Roofing Is East Los Angeles’s Preferred Roof Repair Company
East Los Angeles homeowners call us for Roof Installation - East Los Angeles and repairs because we don’t treat this area like any other job site. We know the difference between a 1920s California bungalow off Whittier Boulevard and a mid-century duplex near Belvedere Park, and we know which roof system on each one is likely to fail first. Our crews stage on tight lots without blocking your neighbor’s driveway, and we tell you exactly who is coming before they arrive. Every technician’s name and photo is sent to you ahead of the visit, and they badge in at the door with a photo ID. That matters to homeowners here who open the door to a stranger and want proof of who’s standing there.
Mercer Roofing is part of the Threshold Group family, founded in 2000. Each location is independently owned and operated under the Threshold Verified standard. That means every technician is background-checked, identity-verified, and held to a quality framework that a corporate fly-by-night can’t fake. East LA customers get a written guarantee on every repair, backed by our 365-Day Done Right Promise: if the work isn’t right within a year, we make it right. No fine print. No phone tag.
Metal Roof Repair in East Los Angeles
Metal Roof Repair in East Los Angeles typically runs $450 to $1,600 depending on whether we’re replacing a damaged panel, resealing a seam, or fixing the flashing where the metal meets a chimney or vent. Metal roofs aren’t common on the original 1920s – 1950s Spanish Revival homes, but they show up on newer rear additions, detached garages, and a handful of mid-century commercial storefronts along East Cesar E. Chavez Avenue. The repair usually takes half a day unless we’re pulling a permit for structural work.
Seam and Fastener Repairs
On standing-seam and corrugated metal roofs, the failure point is almost always the seam or the fastener gasket, not the panel itself. We identify the exact leak path, replace failed gaskets with compatible hardware, and reseal the seam with a manufacturer-recognized sealant. A targeted seam repair in East LA runs $350 to $800, and we can usually finish it in a couple hours.
Flashing Transitions on Metal Roofs
Where a metal roof meets a stucco wall or a chimney, the flashing takes the abuse. East LA’s dry-season heat expands and contracts the metal, eventually cracking the old flashing and opening a slow leak that shows up during winter storms. Replacing that transition flashing costs $600 to $1,400 depending on access and how much of the surrounding roof has to be lifted.
Commercial Roof Repair in East Los Angeles
Commercial Roof Repair in East Los Angeles spans a wide range because the building stock is mixed: small retail strip centers, auto shops, churches, and older apartment buildings with parapet-edged flat roofs. A basic patch on a modified-bitumen roof starts around $800, while a full drain replacement or a 200-square-foot re-roof section can reach $4,500 to $9,500. We pull county permits for any job that triggers them, and we work around your business hours so you’re not closing down for a roof repair.
Flat Roof Patches and Drain Clearing
Flat commercial roofs in East LA fail at the drains first. Debris from nearby trees and dry-season dust clogs undersized interior drains, water ponds, and the membrane eventually cracks under the weight and heat. We clear the drain, replace the surrounding membrane, and confirm the slope still moves water before we leave. A typical drain-area patch runs $800 to $1,600.
Parapet and Edge Metal Repairs
Parapet walls are common on East LA’s mid-century commercial buildings, and the edge metal where the roof meets the parapet is where wind-driven rain gets in. Santa Ana winds work that edge metal loose every season. We resecure or replace the edge metal and reseal the transition before water finds its way into the interior. Expect $900 to $2,400 for a typical parapet edge repair.
Trusted Brands We Service in East Los Angeles

Whether your Spanish Revival bungalow carries original clay tile or a 1980s re-roof put Atlas concrete tile over it, we match the right materials and keep common replacement parts stocked locally so turnaround here is fast. You won’t wait a week for a part to ship from out of state.
Common Roof Repair Problems We See in East Los Angeles Homes
- Flat rear additions failing while the front tile looks fine. The pitched clay tile on the front slope of a 1920s bungalow often has decades of life left, but the flat built-up or modified-bitumen rear addition behind it is leaking through a clogged interior drain. The first inspection targets the wrong roof.
- Santa Ana wind damage to clay and concrete tile. East LA sits far enough inland to catch sharp Santa Ana gusts every fall and early winter. Loose or cracked tile gets dislodged, flashing bends, and water enters at penetrations that only show leaks during the short winter storm window.
- Hidden double-layer tile from 1970s – 80s re-roofs. A generation of East LA re-roofs installed concrete tile directly over original clay without tear-off. That doubles the weight on rafters sized for a single course and traps moisture between layers. The problem only becomes visible once an estimate is already underway.
- Undersized drains on parapet-edged flat roofs. Duplexes and small multi-family rentals from the mid-century era almost always have interior drains that are too small and chronically clogged. A rainless summer bakes the membrane brittle, then the first real storm of winter turns the roof into a pond and the leak into an emergency.

FAQs About Roof Repair in East Los Angeles
Because East Los Angeles is an unincorporated LA County community, not a city, so roofing permits are issued by LA County’s Department of Public Works rather than the City of LA’s LADBS. A roofer who works both sides of the boundary and assumes City of LA rules apply will file with the wrong office and delay your repair. We pull county permits as a matter of course when a repair triggers them, and we can tell you before work starts whether yours will. Call (743) 200-8347 for an exact assessment.
The flat rear addition almost always fails first, often years before the clay tile on the front slope shows any sign of trouble. The original tile on a 1920s – 1950s Spanish Revival home can last decades, but the flat built-up or modified-bitumen roof behind it sits in full sun all summer, bakes brittle, and then leaks through its clogged undersized drains during winter storms. If you’re seeing water stains near the back of the house, the rear addition is your likely source. Call (743) 200-8347 to have us check both systems in one visit.
Yes, Santa Ana winds in East LA regularly crack or dislodge original clay and concrete tile, especially on the upper slopes and ridges. The real damage is rarely just the missing tile: it’s the opening left at the flashing and penetrations underneath, where water will get in during the next storm. A repair that replaces the tile and reseals the flashing fixes both problems. We can inspect your roof after a wind event and give you a written price before any tile is touched. Call (743) 200-8347 to schedule a look.
We stage our materials on the street or in your driveway, never on a neighbor’s property, and we keep the work area contained so debris doesn’t drift onto shared walls or patios. If your home shares a party wall, we give adjacent neighbors a heads-up before we start, and we follow local work-hour rules so the noise stops when it’s supposed to. The access situation on a tight lot also affects your quote: a roof we can’t reach with a ladder from your own property costs more to stage. Call (743) 200-8347 and we’ll factor that into a written estimate, not surprise you with it later.
We check for the telltale signs before we write the estimate: a second nail line, visible tile edges that don’t match the original clay, or sheathing that sags under the extra weight. If a 1970s – 80s re-roof put concrete tile directly over the original clay, that’s a double-layer load the rafters were never sized for, plus trapped moisture between the courses. We’ll tell you exactly what we find and what it means for your repair cost before you commit to anything. Call (743) 200-8347 for a free inspection and written price.
