Why Mercer Roofing Co Thousand Oaks Is Agoura Hills’s Preferred Roof Installation Company
Agoura Hills isn’t Thousand Oaks, and roofing here comes with its own rulebook. The unincorporated hillside parcels fall under LA County permitting, not city, which changes what your roofer has to document before the inspector ever shows up. We know this because we’ve pulled those permits, passed those WUI inspections, and fixed the jobs where another crew got it wrong.
Homeowners here tend to ask the same question: will the crew show up when they say, and will I know who’s walking onto my property? Yes. Every technician’s name and photo is sent to you before arrival. When they knock, they’re in a marked uniform with a photo ID badge. That’s the Threshold Verified standard, and every Mercer technician is held to it. Grant Whitlock leads our team, and he holds the bar high: background-checked, identity-verified, and accountable to the written guarantee on every installation.
Our reviews from Agoura Hills customers mention the same things: the price didn’t change mid-job, the crew cleaned up, and the roof passed inspection the first time. We mark that as a win on every acreage property. Fewer callbacks, fewer surprises, and a roof that doesn’t fight the Santa Anas.
Styles & brands we work with
Shingle Roof in Agoura Hills
A shingle roof in Agoura Hills means an architectural asphalt system rated to handle heat, wind, and the county’s fire-code scrutiny. It’s the most common choice for the 1960s-80s ranch homes and Mediterranean-style properties across the city. We install GAF Timberline HDZ and CertainTeed Landmark lines most often here, because their Class A fire rating clears WUI inspection without debate. A typical shingle roof installation in Agoura Hills runs $9,500 – $18,000 on a standard lot, and more on hillside acreage where access and decking repair add labor.
Class A Fire-Rated Assembly
In a Very High Fire Hazard Severity Zone, the shingle itself isn’t enough. The county inspector checks the full assembly: decking, underlayment, shingles, and vents. We pair GAF or CertainTeed shingles with ember-resistant vents and proper valley shielding so the whole roof meets Class A, not just the shingle label.
Decking Replacement Before the Shingles Go Down
On older Agoura Hills homes, the plywood decking under the shingles is often delaminated or dry-rotted, especially where original wood shakes trapped moisture. We inspect every sheet after tear-off and quote decking replacement by the sheet, so it’s in the written price before we start, not an add-on at the end.
Standing Seam Metal Roof in Agoura Hills
A standing seam metal roof in Agoura Hills is the long-view choice for homeowners on exposed ridgelines and in Old Agoura’s oak canopy, where sparks and wind-borne debris find every seam. Panels run vertically from ridge to eave with concealed fasteners, so there’s no exposed hardware to loosen in 60-mph Santa Ana gusts. A standing seam installation in Agoura Hills typically runs $24,000 – $48,000, driven by panel gauge, roof complexity on hillside geometry, and the tear-off of old wood shake or shingle.
Class A Metal with Ember-Resistant Detailing
Metal is inherently fire-resistant, but the venting and flashing can still fail WUI inspection if done generically. We detail ridge and eave trim with ember-resistant venting, and we flash valleys to LA County’s current WUI standard. On Old Agoura lots under heavy oak leaf litter, we also spec gutter systems sized for the load.
Hillside Roof Geometry and Long Panel Runs
Agoura Hills acreage roofs often have complex valleys, dormers, and long runs that hand-cut metal crews struggle with. We measure each roof plane digitally, then order panels pre-cut to within a quarter inch. That reduces on-site waste and means fewer seams on a 40-foot ridge. You pay for what’s installed, nothing more.
Trusted Brands We Service in Agoura Hills
We install and service shingle systems from GAF, CertainTeed, Owens Corning, and Boral, plus standing seam metal from leading manufacturers recognized by those brands’ warranties. Because we stock common GAF and CertainTeed components for Agoura Hills jobs, we don’t wait on a distribution run when a ridge cap or vent is short. For WUI-zone replacements, we keep Boral’s Class A steel-and-stone coated profiles in our ordering rotation, because they clear county inspection and hold up to leaf litter and sun without the flammability of old wood shakes. Your written estimate names the exact product line, color, and warranty term before you sign.

AfterCommon Roof Installation Problems We See in Agoura Hills Homes
- County permitting surprises on unincorporated lots. Agoura Hills addresses outside city limits fall under LA County jurisdiction, and the inspector enforces WUI and septic setback rules that city-quoting roofers miss. If the documentation isn’t filed with the permit, the final sign-off stops at inspection.
- Ember intrusion through non-compliant vents. Standard off-ridge vents and open bird holes on a WUI-zone roof invite wind-driven embers into the attic during Santa Ana events. That’s a known ignition path, and it’s a direct code failure on replacement.
- Unstable hillside access for material delivery. Steep driveways on acreage lots force crews to hand-carry bundles or bring in all-terrain lifts. Contractors who underpriced the labor then cut corners on underlayment or nailing pattern, and the roof fails early.
- Old wood shake decks hiding rot. Homes built in the 1960s and 70s in Old Agoura and Liberty Canyon often still carry original wood shake over skip sheathing. The decking underneath is frequently soft, and a shingle install over that substrate won’t last or pass inspection.

FAQs About Roof Installation in Agoura Hills
Yes. Acreage parcels in the unincorporated hills fall under LA County permitting, not the City of Agoura Hills, and the county requires documentation tied to your specific lot before roof work is approved. That includes the plot plan showing septic tank and leach field locations, well setbacks if applicable, and the WUI compliance checklist for the roof assembly. We pull the permit and file the paperwork with the county for you, then walk the inspection with the inspector. Call (805) 309-3314 and we’ll verify your parcel’s exact status before quoting.
They determine where equipment can drive, where materials can be stacked, and how crews move around the house. On an acreage property off Chesebro Road in Old Agoura, we mapped the septic tank and leach field from the LA County plot plan before quoting, then staged GAF shingles and decking at the driveway edge so no truck rolled over the drain field. A roofer who ignores setbacks can compact the soil, crack a leach line, and leave you with a failed septic system they won’t fix. We treat the entire lot as part of the job scope, not just the roof plane.
Because the roof already fails WUI fire-resistance requirements, and the county won’t issue a repair permit that leaves non-Class A material in place. In Very High Fire Hazard Severity Zones, the inspector requires the entire roof assembly be brought to Class A: decking, underlayment, shingles or metal, and ember-resistant vents. On that Chesebro Road job, we removed a 1970s wood shake system, replaced delaminated decking, and installed a full GAF Timberline HDZ roof with O’Hagin ember-resistant ridge vents. The county approved it on the first visit. If you’ve been told your shake roof can be patched, get a second look from someone who treats a patch as a code liability against the home itself. Call (805) 309-3314 for an assessment that tells you the truth.
It can, and it usually means more than just a second roof. A detached ADU or shop on an acreage lot has its own setback requirements, and its roof often ties into new trenching for power, water, and drainage. We scope the ADU roof as part of the full property, including the tie-in flashing where the new structure meets the main roofline, and we coordinate with the county’s plan check for WUI compliance on auxiliary structures. The written quote includes the ADU roof, flashing, and any restructuring of drainage that the grade change creates, so you don’t get a separate surprise invoice later. Free estimates are available at (805) 309-3314.
Ask for a roof system rated for at least 110 mph wind uplift, and insist the manufacturer’s installation requirements are followed to the nail. That means a high-wind nailing pattern, specific underlayment attachment, and sealed valleys and eaves that don’t lift in sustained gusts. On ridgeline homes in Agoura Hills, the wind isn’t uniform; it funnels through canyons and hits the roof from multiple angles. We spec GAF Timberline HDZ or CertainTeed Landmark with their high-wind installation details, and we document the nailing during tear-off with photos, so you and the warranty have proof. For an exact wind-rated quote on your specific ridge, call (805) 309-3314.
