Fast, Reliable Roofing Company Across Lennox
Mercer Roofing Co Los Angeles handles roof repair, replacement, and maintenance for homeowners throughout Lennox, CA. Lennox is an unincorporated Los Angeles County area, which means roofing work here follows County of Los Angeles Building and Safety codes rather than a city’s own rules. That distinction catches a lot of homeowners off guard, so we make sure every Lennox job starts with the right permits in place. A typical roof repair in Lennox runs $450 – $1,800, while full roof replacements on the area’s post-war homes usually land between $9,500 and $22,000 depending on roof size and material. For a free estimate, call (213) 521-8272.
Why Mercer Roofing Co Los Angeles Is Lennox’s Preferred Roofing Company
Lennox homeowners call us because we understand what sits on top of their houses. The area’s housing stock is mostly post-World War II single-family homes and mid-century apartment buildings, many still carrying original wood shake or worn asphalt shingles. We have walked dozens of Lennox roofs near Lennox Park, along Inglewood Avenue, and through the residential blocks off Hawthorne Boulevard, and we know what decades of Santa Ana winds and coastal sun do to them.
Our Roofing Company team operates under the Threshold Verified standard, which means every technician who steps onto a Lennox property is background-checked, identity-verified, and arrives in a clean, marked uniform with a photo ID badge. Before the visit, you get the technician’s name and photo sent to you. No stranger-at-the-door surprises. That matters here, where many residents are older homeowners or families with young kids who want to know exactly who is coming up the driveway.
Mercer Roofing was founded in 2000 and is part of the Threshold Group family of home-service companies. Every repair we do in Lennox includes a written guarantee, and if that repair fails within 365 days, we return and make it right at no charge. Every job also starts with a written price before any work begins. No exceptions.

Roof Maintenance in Lennox
Roof Maintenance in Lennox is not optional, not with the combination of intense sun, Santa Ana winds, and the occasional heavy winter rain that this part of Los Angeles County gets. A maintenance visit runs $195 – $450 for most Lennox homes and includes a full inspection, debris clearing from valleys and gutters, a check of flashing points, and caulking or sealing of minor trouble spots before they turn into leaks. Given how many Lennox roofs carry old evaporative coolers, we also inspect and test those curbs and flashings during every maintenance call, because that is where we find the most hidden damage.
Seasonal Checks After Santa Ana Winds
Santa Ana winds can lift shingle edges, tear loose flashing, and fill valleys with debris. After a sustained wind event, we recommend a visual check. Our maintenance visits include a written report with photos, so you see what we see, not just a verbal summary.
Flat and Low-Slope Roof Upkeep
Many Lennox commercial buildings and a fair number of older homes have flat or low-slope roofs. These need periodic coating and seam inspection. We schedule maintenance on flat roofs to catch ponding water before it degrades the membrane, which is far cheaper than replacing a whole section.
Roof Coating in Lennox
Roof Coating in Lennox is one of the most cost-effective ways to extend the life of a flat or low-slope roof. With Lennox’s coastal sun beating down year-round, a quality elastomeric coating reflects heat, seals hairline cracks, and adds years to the roof’s life. A typical coating application for a Lennox flat roof runs $2,800 – $6,500 depending on square footage and surface condition. We use reflective coatings designed for Southern California’s UV load, and every coating job includes a written guarantee.
Elastomeric Coatings for Sun Exposure
Lennox gets enough direct sun to dry out and crack bare roofing materials. An elastomeric coating stretches with temperature swings and blocks UV degradation. For homes and commercial buildings with aging flat roofs, coating can postpone replacement by five to ten years when applied at the right time.
Coating vs. Replacement on Older Lennox Roofs
Not every roof should be coated. If the underlying decking is soft or the membrane is badly split, coating only hides the problem. We inspect first, then tell you honestly whether coating will hold or whether replacement is the better long-term move. That written honesty, before any work starts, is how we do every Lennox job.
Trusted Brands We Service in Lennox
We install and repair roofing systems from manufacturers whose warranties and performance records hold up under Lennox conditions. That includes GAF architectural shingles, which we recently used on a 1960s wood shake replacement near Lennox Park, and Atlas and Tamko products for homeowners who want specific color or profile options. Because our Los Angeles supply coordination serves Lennox directly, we can get materials on site without the long delays that plague open-lot and acreage deliveries here. You get a written line-item price for materials before work starts, with no vague allowances.

AfterCommon Roofing Company Problems We See in Lennox Homes
- Swamp cooler leaks: Many Lennox roofs still carry evaporative coolers that were installed decades ago. If the cooler curb and flashings are not re-flashed during a re-roof, the new roof leaks within months, and we see this failure again and again on homes where a previous contractor skipped the step.
- County permit confusion: Lennox is unincorporated, so roofing projects fall under Los Angeles County Building and Safety, not a city permit office. Contractors who do not pull county permits can get a stop-work order on your open lot, leaving the job half-finished.
- Dried-out asphalt shingles: The coastal sun and Santa Ana winds dry out shingle surfaces faster than homeowners expect. Granule loss, curling edges, and cracking are common on Lennox roofs that are 15 to 20 years old.
- Flat roof ponding: Low-slope and flat roofs in Lennox, especially on commercial buildings along Hawthorne Boulevard and Inglewood Avenue, collect water at low points. Without proper drainage and coating, this ponding degrades the membrane and shortens roof life considerably.
Pricing for Roofing Company in Lennox, CA
Roof repair in Lennox typically runs $450 – $1,800 for common issues like flashing leaks, shingle replacement, and small penetration sealing. A full roof replacement on a standard Lennox single-family home runs $9,500 – $22,000, with materials like GAF architectural shingles pushing to the higher end and basic composition shingles on a simple roof falling lower. Roof coating on a flat or low-slope roof runs $2,800 – $6,500. Factors that move the price: roof square footage, pitch, number of penetrations like swamp coolers or vents, whether the old decking needs replacing, and how far the property sits from a drivable access point on acreage lots.

FAQs About Roofing Company in Lennox
Roofing projects in Lennox require permits from Los Angeles County Building and Safety, not a city permit office, because Lennox is an unincorporated area. We pull the county permits for every Lennox job and confirm they are posted before work begins. Call (213) 521-8272 and we will verify what your specific property needs.
We reframe the cooler curb, re-flash every penetration, and seal openings with ice and water shield before installing the new roofing system. Skipping this step is the most common reason a new Lennox roof leaks within months. During our recent wood shake replacement near Lennox Park, we tore off the old shake, rebuilt the cooler curb, and re-flashed it before any shingles went down. Call (213) 521-8272 if your Lennox home has a roof-mounted cooler – we check those flashings first on every leak call.
Yes. Properties with long driveways, limited turnaround space, or structures set far back from the road add material haul and equipment access time to a roofing quote. We scope access before quoting, so the written price you get accounts for delivery windows and crew logistics, not change orders later. Call (213) 521-8272 for a free, line-itemed estimate that covers the access realities of your property.
For Lennox commercial buildings, we recommend torch-down modified bitumen or single-ply membranes paired with reflective elastomeric coatings, both suited to the area’s sun load and occasional heavy rain. The right system depends on roof traffic, drainage, and whether you have equipment mounted on the roof. We inspect, then give you a written recommendation with real dollar figures. Call (213) 521-8272 to schedule the inspection.
We check the roof’s slope, the condition of gutters and downspouts, and where water currently discharges before replacing any roofing system. On open lots, poor drainage away from the building can undermine the foundation, so we flag grading issues and correct roof drainage as part of the replacement scope. Call (213) 521-8272 and we will walk your property before quoting, so grading and drainage are part of the written price, not an afterthought.
Our crew recently replaced a 1960s-era wood shake roof on a single-family home near Lennox Park with GAF architectural shingles. We started by tearing off the old shake and checking the roof-mounted swamp cooler flashings, which had been leaking into the soffit for years. After installing new decking, underlayment, and drip edge, we reframed the cooler curb and sealed every penetration with ice and water shield before adding ridge vents for county-required ventilation. That is the kind of Lennox-specific work we do every week.
