We’re Ridgeline Roofing Co., and we’ve been serving the Conejo Valley since 1984 - long enough to remember when Lynn Road was two lanes and the Oaks Mall was new construction. Our crews are background-checked, uniformed, and trained to handle the specific fire-code and wind-load requirements that make Thousand Oaks roofing different from coastal Ventura County work. Call (844) 563-1816 any time, day or night - a live person answers, and we’ll get a technician to your home in Thousand Oaks quickly.
Why Ridgeline Roofing Co. Is Thousand Oaks’s Preferred Roof Replacement & Installation Company
We’ve been climbing roofs in Thousand Oaks for over 42 years. That means we’ve replaced the original cedar shakes on the ranch homes near Wildwood Regional Park, upgraded the split-levels off Moorpark Road, and handled emergency tarping after Santa Ana wind events stripped shingles clean off hillside homes in the 91362 zip.
Our reputation here is built on showing up when we say we will and standing behind the work. The 90-Day Done Right Promise means if something isn’t right, we come back and make it right - no paperwork gauntlet, no arguing. Pete Navarro started this company in 1984 on the principle that a contractor should still be in town when the warranty matters.
Every call to (844) 563-1816 reaches a live person, 24 hours a day. Not a callback window. Not a voicemail tree. When a wind event hits the 91360 hillside zone at 2 a.m. and shingles are peeling back, that matters.
Our technicians document every inspection with photos from your actual roof - not a driveway conversation. We install GAF, CertainTeed, and Owens Corning products with proper authorization, no substitutions. For homeowners who’ve lived in their Thousand Oaks house twenty-plus years and plan to stay, that’s the square deal.
Our Roof Replacement & Installation Services in Thousand Oaks
Full Roof Replacement
In Thousand Oaks, a full replacement is rarely just about worn shingles. The city’s master-planned housing stock from the 1960s-1980s is hitting the 40-60 year mark, and many hillside homes were originally roofed with wood shake - now prohibited in CAL FIRE Very High Fire Hazard Severity Zones. We handle the complete tear-off, deck inspection, and code-compliant re-roof with Class A materials, including the fire-rating documentation Ventura County requires on every VHFZ permit application. A typical full replacement in Thousand Oaks runs $15,000-$28,000 for standard asphalt, $22,000-$38,000 for concrete tile, and $28,000-$45,000 for standing-seam metal.

Tile Roofing
Concrete and clay tile dominate Thousand Oaks’s upscale hillside neighborhoods - the Spanish Colonial and Mediterranean-influenced homes near North Ranch and the 91362 elevations. Tile handles our heat and UV exposure well, but the underlayment beneath it fails long before the tile itself. We specialize in lift-and-relay jobs where possible, and full replacement with upgraded synthetic underlayment when the deck requires it. Tile replacement in Thousand Oaks typically costs $22,000-$38,000, with fire-rated concrete tile being the standard specification for VHFZ compliance.

Asphalt Shingles
GAF Timberline HDZ and CertainTeed Landmark shingles are the workhorse choice for Thousand Oaks’s ranch and split-level tract homes - Class A rated, wind-rated to 130 mph, and cost-effective for homeowners who need code compliance without the weight of tile. In the 91360 and 91362 hillside zones, we specify enhanced nail patterns and starter strip configurations to resist Santa Ana uplift. Standard architectural shingle replacement runs $12,000-$20,000; premium designer shingles run $18,000-$26,000.

New Construction Roofing
We’re not the biggest new-construction outfit in Ventura County, but we take select custom home and addition projects in Thousand Oaks where the homeowner wants the same crew that handles their future maintenance. We coordinate with local framers and inspectors, specify proper ventilation for our hot, dry climate, and ensure CAL FIRE compliance from the first permit submission.

Metal Roofing
Standing-seam and stone-coated metal systems are gaining traction in Thousand Oaks’s modern and mountain-contemporary builds, particularly where homeowners want non-combustible coverage with a 50+ year lifespan. Metal runs $28,000-$45,000 installed but eliminates the re-roof cycle entirely.

Flat Roofing
Low-slope sections on Thousand Oaks’s split-levels and patio covers require different materials - TPO, modified bitumen, or built-up systems. We handle these as part of full replacements or standalone repairs, with proper drainage design for our occasional but intense winter rain events.

Trusted Brands We Service in Thousand Oaks
We’re authorized installers for GAF, CertainTeed, and Owens Corning - the three brands we specify most often for Thousand Oaks’s fire-code and wind-resistance requirements. We don’t substitute materials without written approval. Our warehouse in the greater Los Angeles area stocks common shingle colors and profiles, so most Thousand Oaks jobs don’t wait on special orders. For tile, we work with Boral and local quarries for color-matched replacements. Every product carries full manufacturer warranty plus our 90-Day Done Right Promise on workmanship.
Common Roof Replacement & Installation Problems We See in Thousand Oaks Homes
- Santa Ana wind damage in hillside zones. The Conejo Valley’s mountain-pass geography funnels hot, dry gusts directly through 91360 and 91362, producing shingle uplift and blow-off that exceeds the original design limits of 40-year-old roofs. We see this more than rain damage.
- Wood shake fire-code non-compliance. Many homes off Lynn Road, North Ranch, and the northern 91360 hills still have original cedar shake. Replacement isn’t optional in VHFZ zones - it’s mandated, and permits require documented Class A assembly ratings.
- Underlayment failure on steep slopes. Hillside homes concentrate runoff in valleys and crickets, accelerating underlayment deterioration. By the time interior staining appears, the deck often needs partial replacement.
- Builder-grade ventilation shortcuts. The 1960s-1980s tract homes throughout Thousand Oaks were built with minimal attic ventilation. Without proper intake and exhaust, heat buildup degrades shingles from beneath and drives cooling costs up.

FAQs - Roof Replacement & Installation in Thousand Oaks
Yes - if your property is in a CAL FIRE-designated Very High Fire Hazard Severity Zone, which includes most hillside and northern Thousand Oaks neighborhoods, your roof assembly must carry a documented Class A fire rating. We specify this on every permit application and use only rated materials. Call (844) 563-1816 and we’ll check your address against the VHFZ map during our free estimate.
Wood shake and wood shingle roofs are prohibited in VHFZ zones and must be replaced with Class A materials such as concrete tile, Class A asphalt shingles, or metal. We replaced the original wood shake roof on a ranch-style home off Lynn Road in the 91360 hillside zone with fire-rated concrete tile. The home had failing underlayment and multiple leak spots; we upgraded to GAF Timberline HDZ shingles (Class A rated) and added a radiant barrier. The permit required us to list the fire-rating classification, which we navigate routinely.
Most asphalt shingle replacements take 2-4 days; concrete tile and metal systems run 5-8 days. Hillside access, VHFZ permit processing, and material availability can extend this slightly. We give you a specific timeline in writing before work begins. Call (844) 563-1816 to schedule.
Some insurers tightened requirements for homes in or near the 2018 Woolsey Fire burn perimeter, particularly in 91360 and 91362 hillside zones. You may face non-renewal or higher premiums if your roof is over 20 years old, uses prohibited materials, or lacks Class A rating. We provide documentation and photos that satisfy most underwriting requirements. Call (844) 563-1816 for a free inspection and report you can submit to your carrier.
Santa Ana wind uplift and blow-off, not rain. The 91360 and 91362 hillside zones experience gusts that exceed original shingle design limits, particularly on aging roofs with brittle sealant strips. After a wind event, we offer emergency tarping and same-day assessment. Call (844) 563-1816 - a live person answers 24/7.
