Fast, Reliable Roof Repair Across West Hollywood
Roof repair in West Hollywood runs $350 to $1,800 for most jobs, with flat-roof patches and flashing work falling in the middle of that range. Our crews work throughout West Hollywood every week, from the Norma Triangle up to the Sunset Strip corridor. When you call (213) 521-8272, a live person answers. You’ll get a written price before any work starts, and we’ll send you the technician’s name and photo before they ring your doorbell.
What makes West Hollywood different is what’s above your head. Mid-century flat roofs, rooftop HVAC units, and a design review board that watches what happens on visible rooflines. We know those roofs. We know what the city expects. And we know how to fix a leak without leaving a patch that a neighbor three blocks up the hill can spot from their balcony.
Why Mercer Roofing Co Los Angeles Is West Hollywood’s Preferred Roof Repair Company
West Hollywood homeowners tell us the same thing: they want to know who’s coming to the door. So we do something most roofers don’t. Every Mercer Roofing technician is background-checked and identity-verified under the Threshold Verified standard. Before they arrive, you get their name and photo. When they show up, they’re in a clean uniform wearing a photo ID badge. You see exactly who you’re letting in.
Our reputation in West Hollywood comes from work done well on older buildings. We’ve repaired built-up roofs on 1950s courtyard apartments off Santa Monica Boulevard, replaced cracked tile on Spanish Colonial homes near West Hollywood Park, and re-flashed HVAC penetrations on commercial rooftops along Santa Monica. Each location is independently owned and operated, but every one of them is held contractually to the Threshold Verified quality framework. Founded in 2000, Mercer Roofing is part of the Threshold Group family of home-service companies, led by Grant Whitlock.
Every repair includes a written guarantee, not a verbal promise. It’s the 365-Day Done Right Promise: if the work isn’t right within a year, we make it right. No fine print. No phone tag. A free second visit if the repair fails. That’s the kind of certainty West Hollywood homeowners are paying for.
Styles & brands we work with
Shingle Roof Repair in West Hollywood
Shingle Roof Repair in West Hollywood most often means working on the smaller number of single-family homes with pitched roofs: the Spanish Colonial and Mediterranean places with clay tile, or mid-century homes that used architectural asphalt shingles from GAF or CertainTeed. A typical shingle repair here runs $350 to $900. If decking underneath has rotted from years of trapped moisture, expect the job to move toward the top of that range once replacement plywood is factored in.
Tile and Shingle Match Work
Clay tile on a 1930s Spanish home off Doheny isn’t something you patch with whatever’s on the truck. We take time to match the profile and glaze color so the repaired section reads as original. For asphalt shingles, we stock common Atlas and CertainTeed colors used across West Hollywood and can source the rest within a day or two through our local supply lines.
Underlayment and Water Intrusion
Most shingle leaks in West Hollywood aren’t from the shingle itself. They’re from failed underlayment, cracked vent boots, or rusted flashing at valleys and sidewalls. We inspect all of it when we’re up there, and we write the findings into the quote so you know what you’re approving before a single nail goes down.
Storm Damage Roof Repair in West Hollywood
Storm Damage Roof Repair in West Hollywood usually follows the first heavy winter rain after a long dry spell. The city’s Mediterranean climate means roofs sit under intense sun for months, then suddenly take water. A typical storm-related repair here is $450 to $1,400, depending on how many penetrations the rain exposed. The pattern we see over and over: a flat roof that looked fine in October leaks in December because the old pitch pans around rooftop HVAC units cracked in the heat and no one noticed until the downpour.
Post-Rain Flat Roof Response
After rain, our Roof Repair team can inspect low-slope and flat roofs across West Hollywood and pinpoint the exact point of entry before it spreads. On a 1960s low-rise off Santa Monica Boulevard, our crew opened a flat built-up roof after a winter rain and found the original decking had rotted around three HVAC penetrations. We replaced the failed flashing with new lead pipe boots, installed a self-adhered ice and water shield around all penetrations, then patched the modified bitumen to blend with the existing silver coating so the patch is invisible from the Norma Triangle overlook.
Visible-Roof Repairs That Pass Review
If your roof is visible from the Sunset Strip, West Hollywood’s design review board takes notice when repair work doesn’t match. We’ve had to strip and redo patches on other companies’ work for exactly that reason. Our crews match membrane color and texture on every visible repair, even on flat commercial roofs where nobody stands close enough to check. The board checks from a distance. So do we.
Trusted Brands We Service in West Hollywood
Mercer Roofing works with manufacturer-recognized shingle and membrane brands including GAF, Atlas, and Tamko. We keep common products stocked for West Hollywood jobs and can source specialized materials fast through local supply houses. That matters when a design review flag means you need an exact membrane color match, not a “close enough” replacement. We service whatever’s up there: built-up, modified bitumen, TPO, tile, and composition shingle, all with the same written price and written guarantee.

AfterCommon Roof Repair Problems We See in West Hollywood Homes
- Rooftop HVAC penetrations on flat roofs. Dozens of pipe boots, pitch pans, and conduit lines all pierce the membrane, and after years of intense West Hollywood sun, those seals crack. A January downpour sends water straight through to the interior below.
- UV-degraded modified bitumen and elastomeric coatings. The long dry season bakes flat roofs until the surface alligators and micro-cracks. You can’t see the damage until the first heavy rain. By then, the water’s already in.
- Failed flashing at clay tile valleys and sidewalls. Spanish Colonial homes hold up well, but the metal around chimneys and at roof-to-wall transitions corrodes. We replace it with proper counterflashing so it outlasts the tile around it.
- Design-review mismatches after a patch. A repair on a roof visible from the Sunset Strip that uses the wrong color or texture gets flagged. We match it correctly the first time, because the board and your neighbors are both watching.

FAQs About Roof Repair in West Hollywood
If the roofline is visible from the Sunset Strip or a neighboring hillside, West Hollywood’s design review board can flag a repair that doesn’t match the existing membrane texture and color. That means a simple patch can become a call-back and a citation if the contractor grabs whatever roll is on the truck. We match the existing silver coating, cap sheet color, and texture on every flat-roof patch, including ones on commercial buildings that most people never see. It adds a little to the cost, but it keeps you clear of board complaints. Call (213) 521-8272 and we’ll tell you if your roofline is in the visibility zone.
Flat roofs collect water in low spots, and West Hollywood’s long dry season lets tiny cracks in the membrane sit unnoticed for months. Then the winter rains hit and pooled water finds every failed seam, crack, and penetration at once. Pitched roofs shed water quickly, but flat roofs don’t. The fix is an inspection before the first big rain, not after the first brown ceiling stain. We can do that inspection now, write up what we find, and give you a price to fix it before it becomes an interior problem.
Ice and water shield is a self-adhered membrane that seals around penetrations, flashings, and roof edges, and it’s the best defense we know against standing-water leaks on low-slope roofs. In West Hollywood, we regularly install it around HVAC curbs, pitch pans, and parapet transitions where we find the highest concentration of leak failures. It is code-appropriate sealed beneath the modified bitumen or cap sheet, not slapped on top, and it performs better than tar alone around penetrations. If your flat roof has been patched repeatedly and still leaks, the answer is usually ice and water shield at the penetration points rather than another coating.
The UV exposure here degrades the top layer of modified bitumen and elastomeric coatings faster than most people expect, leading to alligator cracking and the slow breakdown of the cap sheet. That’s why a roof that looked fine in summer leaks in winter: the sun broke the surface, and the rain found the cracks. A silver coating helps reflect some UV, but it ages, too. If you’re seeing alligator cracks on a low slope or flat roof in West Hollywood, call us at (213) 521-8272 for a quote to re-coat or patch before winter testing.
Yes, a section repair is usually possible, especially if the rest of the membrane is in reasonable shape. But when we find rot around HVAC penetrations or extensive cracking elsewhere, a partial patch can become a fail-and-refail cycle. Our rule is simple: fix only what needs fixing, and tell you if the rest of the roof is close to needing work so you can plan for it rather than be surprised. For flat roofs in the Norma Triangle and adjacent areas, we write that assessment into the quote so you can make a real decision.
