Why Mercer Roofing Co Los Angeles Is Los Angeles’s Preferred Roofing Company
Homeowners in Los Angeles call us because we treat their home as a place to be protected, not a job site. Every Mercer technician arrives in a clean, marked uniform with a photo ID badge, and their name and photo are sent to you before they even ring the bell. That’s the Threshold Verified standard we’re contractually held to, and it matters when you’re home alone or have young kids.
We’ve re-roofed homes from Silver Lake to the Valley, and Los Angeles homeowners keep our number because we put everything in writing. Your price is set before the first shingle comes off, and your repair guarantee covers 365 days. If the repair fails within that year, we come back free. No arguments, no fine print.
Grant Whitlock leads our Los Angeles team with a simple rule: if it’s not done right, we make it right. That promise is printed on every invoice, not just recited on a sales call.
We also dispatch locally. Scheduling and dispatch are coordinated from our Los Angeles office, and our crews live and work in the neighborhoods they serve. We know what a Santa Ana wind season does to a ridge vent in Sherman Oaks, because our guys drive past those homes every day.
As part of the Roofing Company team serving Los Angeles, we stock the materials that match this city’s housing stock, from clay tile to modified bitumen, so we’re not waiting on a warehouse three states away.

Roof Coating in Los Angeles
A Roof Coating in Los Angeles is a protective layer applied over an existing flat or low-slope roof, and it’s one of the smartest investments a homeowner here can make given our sun load. On a typical Los Angeles flat roof, a silicone or acrylic coating runs $4 to $7 per square foot, meaning most homes land between $2,800 and $6,500. The coating reflects UV instead of absorbing it, which can cut rooftop surface temperatures by 30 to 50 degrees and extend the life of the underlying roof by a decade or more.
We see the most demand for coating in neighborhoods like Silver Lake, Echo Park, and Koreatown, where flat-roofed apartments and bungalows from the 1920s and 30s dominate. The original built-up roofs hold up surprisingly well, but the top layer eventually dries out and cracks under years of Los Angeles sun. A properly applied coating stops water intrusion before it reaches the decking.
When Roof Coating Works
A coating works best when the underlying roof is still structurally sound and dry. If the decking is rotted or the roof is actively ponding water, coating over it just traps moisture. We inspect first, every time, and we’ll tell you honestly if coating will buy you years or if you’re better off replacing the roof.
What to Expect During Application
We clean the surface, repair seams and flashing, then apply the coating in two passes so you get the full mil thickness the manufacturer requires. Most Los Angeles flat roofs are coated in one day, and you can walk on it within 24 hours, though full cure takes longer.
Free Roof Estimate in Los Angeles
A Free Roof Estimate in Los Angeles means we come out, inspect your roof thoroughly, and hand you a written quote you can hold me to. No phone-only guesses, no verbal ranges that shift later. The estimate takes about 45 minutes to an hour, and you keep the written number whether or not you hire us.
The most valuable part of our Los Angeles estimates is the attic inspection. In this city, the difference between a $10,000 re-roof and a $17,000 re-roof is usually hidden decking rot, and the only way to know is to get under the roof. We check the sheathing, the ventilation, and the flashing condition before we give you a number, because quoting over the phone and discovering rot after tear-off is how homeowners get burned with triple-the-estimate change orders.
What the Estimate Includes
You’ll get a line-by-line breakdown: materials, labor, disposal, permit fees, and any anticipated decking replacement based on what we see in the attic. We write allowances into the contract for decking, so if we find rot during tear-off, you already know the per-sheet price and the worst-case total.
How to Compare Our Numbers
Most Los Angeles roofing quotes come per square, which is 100 square feet of roof area. So a 20-square roof is roughly 2,000 square feet. Ask every contractor for their per-square price and their decking replacement rate. That’s the quickest way to see who’s hiding margin and who isn’t.
Trusted Brands We Service in Los Angeles
We install and repair roofs using manufacturer-recognized shingle systems from GAF, Atlas, and Tamko, along with Boral tile for homes where the original Spanish or Mediterranean character matters. For flat roofs, we work with the modified bitumen and single-ply systems that dominate Los Angeles apartment stock. We keep common profiles and colors stocked locally for faster turnaround, so a cracked tile on a Boral roof in Los Angeles doesn’t sit open to the weather while we special-order from a distribution center. If your home has a discontinued profile, we’ll color-match a current tile as closely as physically possible and show you a sample before we install it.

AfterCommon Roofing Company Problems We See in Los Angeles Homes
- Sun-cracked underlayment on low-slope tile roofs. Los Angeles gets roughly 3,000 hours of sunshine a year, and that UV load bakes the underlayment beneath clay tiles until it turns brittle. Most 1920s-era tile roofs in Hollywood and Hancock Park are on their second or third underlayment by now.
- Santa Ana wind damage at ridge vents and dormer flashing. Seasonal winds here reliably gust to 50 mph in the passes and canyons. The first point of failure is almost always the ridge vent or a dormer’s step flashing, where lifted shingles let water under the decking.
- Decking rot at tile penetrations on older homes. On pre-1950 roofs with skip sheathing, water seeps in around plumbing vents and chimneys and rots the boards. You won’t see it from the street, but you’ll find it the moment you lift a tile.
- Wildland-Urban Interface code violations in brush zones. Hillside homes in areas like the Hollywood Hills or Bel Air fall under WUI fire codes that require specific fire-resistant underlayments and assemblies. Reusing old combustible materials here fails final inspection.
Pricing for Roofing Company in Los Angeles, CA
Let’s talk real numbers for Los Angeles. A full-roof replacement with architectural shingles on a typical 1,800-square-foot single-story home runs $9,500 to $14,000. Larger homes, steeper pitches, and full decking replacement can push that to $18,000 or more. Clay tile work, common in Hancock Park and Los Feliz, typically runs $1,800 to $2,400 per square for replacement, because the tile itself is heavy, specialized labor is required, and matching vintage profiles commands a premium. Flat roof replacement on a standard Los Angeles apartment or bungalow runs $6,500 to $12,000, and a re-coat rather than a full tear-off lands between $2,800 and $6,500. The variables are roof size, pitch, decking condition, and material class. The estimate is free, and the number we give you is the number you’ll pay unless we find hidden damage, and if we do, we’ll show you photos and a signed change order before we proceed. Call (213) 521-8272 for your free estimate.

FAQs About Roofing Company in Los Angeles
No. A Los Angeles reroof permit does not automatically require full decking replacement. The city requires that existing decking be sound and properly nailed, and any rotted or delaminated sections must be replaced before new roofing goes on. The key detail is that this isn’t the contractor’s discretion, it’s the inspector’s determination. In older Los Angeles homes with skip sheathing, code allows reuse if the boards are intact and meet the nailing pattern, but gaps wider than the code allows must be closed. We write decking replacement into the contract as a per-sheet allowance so you know the ceiling cost before we start. Call (213) 521-8272 and we’ll explain exactly how the permit for your roof would work.
Your neighbor likely needed a crane because their street is too steep, too narrow, or too tree-lined for a standard material delivery truck to reach the roof directly. In the Hollywood Hills, many streets can’t accommodate a boom truck, so a crane hoists pallets of tile or shingles over the house and onto the roof. Whether you’ll need one depends on your street’s grade, the turning radius, and overhanging vegetation. We’ll assess that during the free estimate and include any crane cost as a specific line item, never a surprise. Call (213) 521-8272 to find out if a crane applies to your roof.
They affect the edges and penetrations more than the field of the coating itself. A properly applied coating system includes reinforced fabric at all terminations, drains, and rooftop equipment curbs, because those are the points where Santa Ana wind and airborne debris can peel a coating if the seam is thin. Wind doesn’t lift a well-adhered silicone or acrylic roof coating across its main surface, but dust and debris carried by the wind can sandblast it over many seasons, so we build up the mil thickness at the leading edges where Silver Lake roofs take the most abuse. Call (213) 521-8272 and we’ll inspect your flat roof before you coat it.
A square is 100 square feet of roof surface area, and it’s the standard unit every Los Angeles roofer uses to price work. So a 2,000-square-foot roof is 20 squares, and if one contractor quotes you $550 per square and another quotes $700, that’s the difference between $11,000 and $14,000 for the same roof. Most of that gap is material grade, warranty length, and labor quality, but you should ask each bidder to show their per-square decking replacement rate too. That’s where the biggest hidden costs hide. Call (213) 521-8272 and we’ll walk you through how our per-square pricing works.
Yes, and this is something we do regularly. The original 1920s clay tiles on Hancock Park homes are irreplaceable, period. They’re no longer manufactured, and the glaze patina that’s developed over a century can’t be replicated from a catalog. When we re-roof these homes, we salvage every intact tile, clean it, and color-match a modern Boral or other clay tile that’s close in body and surface tone. The match is never perfect up close, but from the street, the roof reads as a continuous surface. We’ll show you a side-by-side sample before we commit. Call (213) 521-8272 to have us look at your tile roof and tell you what’s salvageable.
