Fast, Reliable Roofing Company Across West Hills

Why Mercer Roofing Co Thousand Oaks Is West Hills’s Preferred Roofing Company

Mercer Roofing was founded in 2000 and operates as part of the Threshold Group family of home-service companies. Each location, including ours serving West Hills, is independently owned and operated and held to the Threshold Verified standard. That’s not a marketing line. It’s a contractual requirement that every technician gets background-checked and identity-verified before they step onto your property.

For West Hills homeowners, that means something concrete. Before your appointment, we send you the name and photo of the technician coming to your door. When they arrive, they’re in a clean, marked uniform and carrying a photo ID badge. You don’t have to wonder who’s walking up your driveway. You’ll know. It’s the single most important safeguard in our industry, and it’s the one most roofers skip because it takes work and follow-through.

Homeowners in neighborhoods like the hillsides above Sherman Way and the properties around Bell Canyon Park choose us because the written price comes before any work starts. Not an estimate scribbled on a clipboard after the fact. A written line-item price. Every repair includes a written guarantee, and if that repair fails within 365 days, we make it right on a free second visit. That’s the 365-Day Done Right Promise, and it applies to every job we do in West Hills.

Grant Whitlock leads our team, and his direction is simple: protect the homeowner from the moment the phone rings. For older homeowners in West Hills who live alone, for parents at home with young kids during the day, that protection changes the entire experience of hiring a roofing company.

Free Roof Estimate in West Hills

A Free Roof Estimate in West Hills is how every Mercer Roofing project begins, and it’s the step that separates a safe, predictable roofing project from a gamble. When we come out to your property, whether it’s in the flatlands near Chase Street or the steep lots above Platt Avenue, we’re not just measuring squares and snapping photos. We’re looking at your drainage, your fascia boards, your septic setback lines if you’re on acreage, and the condition of your underlayment. Then we give you a written price. No estimate means no work starts. That’s not our preference; it’s our rule.

What the Estimate Covers

We walk the roof plane by plane, check flashing around chimneys and dormers, and note any decking that’s begun to rot. We also check for signs of ember intrusion risk, which matters on hillside lots in West Hills where wildfire season is real. The estimate shows material costs, labor, debris hauling, and any permit fees broken out as line items.

How Long It Takes

Most roof estimates on single-family homes in West Hills take 45 to 90 minutes, depending on how many roof planes and penetrations we’re assessing. On larger acreage properties, like those with detached ADUs or workshops, we’ll schedule extra time so the written price covers everything at once. You’ll have the number in your hand before we leave, or we’ll email it the same day.

Roofing Contractor in West Hills

A Roofing Contractor in West Hills has to understand one thing that flatland roofers miss: this community isn’t a single uniform grid. You’ve got mid-century ranch homes near the Valley Circle corridor with low-slope roofs, you’ve got two-story traditionals with dormer-and-valley complexity, and you’ve got hillside custom homes where the roof is an architectural feature. Mercer Roofing Co Thousand Oaks runs full repair, replacement, and installation crews that know how to handle all three, and we never send a general laborer to do a roofer’s job.

Permits and County Approvals

West Hills sits primarily in unincorporated Los Angeles County, not City of LA territory. That means roof replacements and major installations can require County of Los Angeles Building & Safety permits, not city permits. If your property is on septic rather than sewer, the county plan check flags required setbacks from the leach field and any private well. We scope this before quoting, not after tear-off. You’ll know your permit cost and schedule as part of the written price.

Multi-Structure Properties

Ranch properties in West Hills often have more than one roofed structure: a main house, a detached garage, sometimes an ADU or a workshop. We can reroof all of them on a single permit package, so you’re not scheduling three separate inspections. The estimate includes all structures, so there’s no surprise change order later.

Trusted Brands We Service in West Hills

We install and repair roofing systems from manufacturers that engineers and inspectors know by name. That includes GAF architectural shingles, Owens Corning duration lines, and CertainTeed products that carry strong wind and impact ratings. If you currently have an IKO or Atlas roof, we service those too. Because we run ongoing projects across West Hills, we can typically source matching product faster than a contractor who’s ordering one-off materials from a supplier in the Valley. Quick material availability means less exposure for your roof deck between tear-off and new underlayment. We also keep common flashing profiles and sealants stocked for tile and flat roof repairs, which shortens the wait on smaller jobs.

Common Roofing Company Problems We See in West Hills Homes

• Wind-driven debris and ember risk on hillside lots. Santa Ana winds coming through the canyons can lift older shingle tabs and send twigs, leaves, and embers under the underlayment. We see this more in the hills above Vanowen Street than in the flatter neighborhoods closer to Canoga Park.
• Rotting fascia boards from irrigation overspray. West Hills homeowners with lush landscaping often have sprinkler heads shooting directly onto fascia and rafter tails. Over a few years, that persistent moisture rots the wood. We replace the board and often redirect the spray as part of the job.
• Flashing failures at multi-plane intersections. Homes with dormers, chimneys, and additions commonly have valley and step flashing that’s decades old. When it rusts or pulls away, water gets into the roof deck. On steep properties, we custom-cut flashing on site to match the actual angle.
• Aging wood shake and original asphalt roofs. Much of West Hills was built between the 1960s and 1990s, and the original roofs are now at the end of their service life. We frequently replace wood shake with GAF architectural shingles or tile, depending on the home’s structure and the county’s requirements.
