Fast, Reliable Roof Installation Across Agoura Hills
A new roof in Agoura Hills typically costs between $14,000 and $38,000 depending on whether you’re replacing a wood shake in Old Agoura with fire-rated composite or laying clay tile on a hillside Mediterranean estate. We schedule roof installations across Agoura Hills within one to three weeks, and every job starts with a written price before we order a single bundle of shingles. If you’re weighing your options, call (341) 217-2677 and a live person answers – day or night. Not a call-back service. A person.
What makes roof installation different in Agoura Hills is simple: the Santa Monica Mountains wildland-urban interface shapes everything. Steep hillside lots, strict WUI fire codes, and a housing stock that runs from 1960s ranches to newer Spanish-style estates mean the right roof is rarely the generic one. Our Roof Installation crew works these streets every week, and we know what the inspectors here look for before we arrive on site.
Why Mercer Roofing Co Woodland Hills Is Agoura Hills’s Preferred Roof Installation Company
We’ve torn off enough original wood shake in Old Agoura to know what’s under it before we quote: usually cedar that’s dried to kindling, skip sheathing, and flashing that’s been leaking quietly for a decade. That local familiarity means our written price reflects what we’ll actually find. No change orders when we lift the first layer and discover the decking situation nobody planned for.
Grant Whitlock runs our crews with a simple standard: every technician’s name and photo is sent to you before they arrive, and they badge in at the door with a photo ID. Uniformed, background-checked, identity-verified. If you’re home alone with young kids or an aging parent, you’ll know exactly who’s on your property before the truck pulls up. That’s the Threshold Standard, and every independently owned Mercer location is contractually held to it.
For Agoura Hills customers specifically, we carry stock on the materials this area demands: Boral composite shakes for Old Agoura replacements, tile adhesives and fasteners rated for hillside uplift, and ridge vent systems sized for the wind loads off the 101 corridor. Dispatch is coordinated from our Los Angeles office; the crews working on your roof are local to the Conejo Valley area and know Chesebro Road from Kanan Road from Reyes Adobe.
Styles & brands we work with
Tile Roof in Agoura Hills
Tile roof installation in Agoura Hills runs $22,000 to $48,000 on a typical home, and it’s the right call for the newer Mediterranean and Spanish-style estates along the hillsides above the 101 and around Morrison Ranch. Whether you’re matching an existing clay profile or switching from a failing composite to tile, the job here means working with tile that Agoura Hills specifically demands: lightweight concrete profiles that cut some structural load, or full clay when the home’s design and the hillside engineer’s report call for it.
Hillside Attachment and Flashing
On a hillside lot, wind uplift is the enemy. Tile roofs in Agoura Hills need mechanical fastening at the eaves, ridge, and hips – not just gravity and hope. We also custom-fabricate flashing at every valley, skylight, and chimney penetration, because the angle of these lots channels water differently than a flat street in West Hills ever would.
What Replacement Costs
A straight tile roof replacement on a 2,200-square-foot single-story in Agoura Hills usually lands between $24,000 and $38,000. Two-story hillside homes with steep access and custom flashing at multiple penetrations push toward $40,000 to $48,000. Every quote includes the written price before work starts, and the 365-Day Done Right Promise backs the install.
Roof Ventilation in Agoura Hills
Roof ventilation in Agoura Hills is not optional – it’s what keeps attic temperatures from baking your tile underlayment or cooking the adhesive on your composite shakes through a 100-degree July. On a ranch home in Old Agoura or a Spanish estate near the Agoura Hills Library, ventilation typically costs $850 to $2,200 when we’re already replacing the roof, and it’s money that extends the life of whatever surface you’re putting on.
Ridge Vent on Santa Ana Wind Loads
Agoura Hills sits in a wind corridor. A ridge vent has to be rated and installed to handle sustained Santa Ana events without letting embers or driven rain penetrate during a wildfire event or a January downpour. We size the vent balance – intake at the eaves, exhaust at the ridge – per roof, not per a manufacturer’s generic chart.
Mid-Century Flat Roof Sections
Some 1960s-70s ranches in Agoura Hills have flat roof sections over additions or carports. Those need dedicated ventilation, often a low-profile turtle vent or an active fan, because the air doesn’t move naturally through a flat section. When we install over these sections, ventilation planning happens before the underlayment goes down, not after.
Trusted Brands We Service in Agoura Hills
We install and service the shingle and shake brands that Agoura Hills homeowners actually ask for, including Owens Corning, IKO, and Atlas. For Old Agoura wood shake replacements, we work heavily with Boral composite shakes because they hold the rustic cedar profile while passing WUI fire code. Our suppliers deliver to Agoura Hills jobsites on a two-to-three-day schedule, which matters when you’re three weeks out from Santa Ana season and the material list just changed.

AfterCommon Roof Installation Problems We See in Agoura Hills Homes
- Improper nailing on architectural shingles. A shingle only carries its 130 mph wind rating if the nailing pattern is dead-on. On exposed hillside lots off Chesebro and Kanan, a few misplaced nails mean a roof that peels during the first Santa Ana event after it’s installed.
- Missing ice and water shield at eaves and valleys. Agoura Hills winter rains aren’t heavy by national standards, but they’re concentrated. On older ranch homes with flat-roof sections, skipping the self-adhered shield at the transition points leads to water intrusion within the first two seasons.
- Reusing old flashing during a shake-to-tile or shake-to-composite swap. Wood shake flashing was never designed for tile or composite profiles. Reusing it means leaks at chimneys, skylights, and sidewalls within months. New roof, new flashing. Every time.
- Ventilation that was never recalculated for the new roof. A wood shake roof breathes differently than tile or architectural shingles. If the attic ventilation isn’t adjusted for the new surface, heat builds up and shortens the life of the entire system.
Pricing for Roof Installation in Agoura Hills, CA
A full roof installation in Agoura Hills runs $14,000 to $48,000 depending on the roof you’re putting on. Composite shakes for an Old Agoura ranch typically cost $18,000 to $28,000. Architectural shingles from Owens Corning or IKO on a 2,000-square-foot home run $14,000 to $22,000. Tile on a hillside estate starts around $22,000 and goes up with structural work and custom flashing. What moves the number: roof pitch and access for the crew, the condition of the decking once we strip the old surface, the number of valleys and penetrations, and whether you’re in a WUI code zone that mandates fire-rated materials. We put the exact number in writing before any work starts. Call (341) 217-2677 and we’ll schedule a free estimate.

FAQs About Roof Installation in Agoura Hills
Boral composite shakes solve it. They carry a Class A fire rating that satisfies Agoura Hills WUI requirements, and they’re molded from real cedar profiles so the roofline keeps the rustic shake look Old Agoura is known for. On a hillside home off Chesebro Road, our crew replaced a failing 1970s wood shake roof with Boral shakes that matched the original profile: stripped to the decking, full self-adhered ice and water shield, custom flashing at every valley and penetration, upgraded ridge vent for Santa Ana uplift. The fire marshal signed off, and the house looks like it did in 1972. In a good way. Call (341) 217-2677 if you want to know whether your Old Agoura roof is a candidate.
Access and attachment. A hillside tile roof in Agoura Hills needs scaffolding or lift work to get materials to the roofline, mechanical fastening at every eave, hip, and ridge per WUI code, and custom flashing work that a flat-lot shingle roof never requires. Figure one to two weeks for a shingle roof, two to four weeks for a hillside tile installation. The schedule is driven by the engineering on the steep sections, not by crew speed. We’ll tell you the timeline in writing before we start.
Most 1960s-70s ranch homes in Agoura Hills were built with minimal ventilation: a few static vents and whatever air happened to move through the shake gaps. When we replace a wood shake roof, we recalculate airflow for the new surface, which usually means adding intake at the eaves and upgrading to a continuous ridge vent or a balanced static vent system. On homes with flat-roof sections over additions or carports, we add low-profile vents or active fans because flat sections don’t move air on their own. A ventilation upgrade during installation typically runs $850 to $2,200.
We treat flat sections as a separate system. That means self-adhered ice and water shield across the entire flat deck, a dedicated membrane system rated for ponding water, and proper drainage at the transition points where the flat section meets the pitched roof. These sections fail because water sits. The fix is a membrane system and flashing detail that gives water somewhere to go. If your Agoura Hills home has a flat section over a carport or addition, we’ll quote it as its own line item so you see exactly what it costs.
No. Installing tile over wood shake in Agoura Hills is a bad idea and we won’t do it. The shake layer prevents you from seeing the decking condition underneath, the weight of tile on top of an old shake system often exceeds what the structure was designed for, and WUI code in Agoura Hills requires a fire-rated assembly that starts at the deck. The right path is strip to the decking, inspect, repair what needs it, install the fire-rated underlayment, then the tile. It takes longer and costs a little more on the front end. It’s the only way the roof actually performs. Call (341) 217-2677 for a written estimate. We’ll show you the full scope, and the price won’t change once we lift the first shake.
