Fast, Reliable Roofing Company Across Oak Park
Roofing work in Oak Park runs $450 – $1,900 for most repairs, $4,500 – $9,800 for a full reroof on a typical 1,800 – 2,600 square foot home, and $180 – $425 for a roof inspection. Those are real numbers from our jobs in the area, not national averages. Oak Park’s steep, multi-plane roofs and Santa Ana wind exposure mean the cheapest quote is rarely the safest bet. We’re Roofing Company specialists who work these hills every week. Call (805) 309-3314 and a live person answers, day or night.
Our crews know Oak Park. We know the 1980s tile subdivisions off Kanan Road, the custom homes climbing the ridgelines, and the way wind whips through the canyons off Lindero Canyon Road. That local knowledge shows up in every inspection report and every quote we write. When you call, you get a written price before any work starts, and a technician whose name and photo are sent to you before they arrive.
Why Mercer Roofing Co Thousand Oaks Is Oak Park’s Preferred Roofing Company Company
Homeowners in Oak Park keep our number because they know exactly who’s coming to the door. Every Mercer technician is background-checked, identity-verified, and arrives in a clean, marked uniform with a photo ID badge. That’s the Threshold Verified standard, and it’s the reason so many parents, people home alone, and older homeowners in Oak Park choose us over a random door-knocker. You get the tech’s name and photo before the visit. No surprises at the door.
Our Oak Park customers also get the 365-Day Done Right Promise in writing. If a repair fails within a year, we come back free and make it right. That’s not a marketing line. It’s on every job ticket. Grant Whitlock, who leads our team, has built the company on this: written prices, written guarantees, and techs who show a badge before they show a ladder. Dispatch and scheduling are coordinated from the brand’s Los Angeles office, but the crews serving Oak Park work locally and know the terrain.
Styles & brands we work with





Roof Inspection in Oak Park
A Roof Inspection in Oak Park costs $180 – $425 and should happen before you buy a home, after any Santa Ana event over 50 mph, or when your roof passes the 20-year mark. Oak Park’s hot, dry summers and steep slopes mean inspection involves more than looking at shingles from the ground. We walk every plane, check flashing at valleys and penetrations, and document what’s actually happening under the tile or shingle.
What a Full Walkover Catches
We check for cracked concrete tile, lifted shingles, corroded drip edge, and dried-out underlayment. On Oak Park’s multi-plane roofs, the valley intersections take the worst of it. A visual walkover from the ground misses maybe half the problems. We get on the roof.
Inspection Reports You Can Use
Every inspection comes with a written report and photos. If you’re buying or selling, that documentation matters. If you’re filing an insurance claim after a windstorm, the report gives you evidence the adjuster can’t argue with.
Commercial Roofing in Oak Park
Commercial Roofing in Oak Park means flat and low-slope systems on the small office parks and retail buildings around Kanan Road and Lindero Canyon Road. These jobs typically run $7,500 – $22,000 depending on square footage and system type. We handle TPO, modified bitumen, and coating systems, and every quote includes a written price before work starts.
Flat Roof Drainage and Ponding
Oak Park’s commercial roofs fail most often at drains and scuppers. Our inspections focus on ponding water, failed seams, and clogged drainage that leads to leaks after winter rains. We document everything in writing.
Minimizing Business Disruption
We schedule work around your operating hours where possible. For occupied buildings, we stage materials carefully and keep the work area clean. You’ll know the crew’s names before they show up.
Trusted Brands We Service in Oak Park
We install and repair shingle and tile systems from CertainTeed, Owens Corning, IKO, and Atlas, among others. Because Oak Park has so many 1980s-era concrete tile roofs, we keep matching tile stock on hand for repairs off Kanan Road. That means when a windstorm cracks or lifts a dozen tiles on your 1987-era roof, we can often match the profile and color without a full replacement. For asphalt shingle homes, we stock common CertainTeed and Owens Corning colors locally, which shortens repair turnaround in Oak Park neighborhoods like Morrison Ranch and Deerhill.
Common Roofing Company Problems We See in Oak Park Homes
- Santa Ana wind damage. Winds over 60 mph lift tiles and shingles on exposed hillside homes, especially on the south- and east-facing roof planes. We find cracked tiles, missing shingles, and broken storm clips after nearly every major wind event.
- Cracked 1980s concrete tile. The original flat tiles from Oak Park’s 1980s subdivisions crack under routine foot traffic. A cracked tile isn’t just cosmetic. Water gets through and rots the decking underneath.
- Baked and brittle underlayment. Oak Park’s hot, dry summers cook the felt under the tile or shingles. By year 20, it’s often brittle and torn, which means leaks even when the outer layer looks fine. Our roof inspections catch this before the next rain.
- Poorly flashed valleys and penetrations. On steep, multi-plane roofs, the valleys and chimney or vent penetrations are where we find the most leaks. Many were flashed incorrectly from the start. We repair them properly, with written guarantees.

AfterPricing for Roofing Company in Oak Park, CA
Roof repair in Oak Park runs $450 – $1,900 for most jobs.

What moves the price: roof pitch, number of planes, tile versus shingle, and whether the decking or underlayment needs replacement. Steeper roofs take more time and more safety equipment.

FAQs About Roofing Company in Oak Park
Hillside and exposed homes in Oak Park typically need a 110 mph wind-load rating under Ventura County code, not the standard 90 mph package quoted for flatter inland lots. Ask your contractor to show the specific fastener pattern, storm clip count, and shingle or tile manufacturer’s wind-rating documentation in the written quote. If the quote doesn’t list these line by line, it’s not a compliant bid. Call (805) 309-3314 and we’ll walk you through what a compliant Oak Park quote should include.
Yes. Oak Park sits in a mountainous area where wildfire ember intrusion is a real concern, and even homes outside the mandated zone face ember exposure during a bad fire year. A Class A fire-rated roof assembly, including the underlayment, is standard practice here and often required by insurers for renewal. We install Class A systems on every reroof in Oak Park, regardless of map lines. Call (805) 309-3314 for details on fire-rated materials.
A pre-reroof inspection costs $180 – $425 and checks the decking, underlayment, flashing, and tile or shingle condition under the surface layer. A visual walkover can’t see rotted decking, torn felt, or hidden tile fractures. On an Oak Park home with a 30-year-old roof, that inspection often finds damage that changes the scope and the price. We document everything with photos. Call (805) 309-3314 to schedule an inspection.
Insurers ask for documentation showing your roof met code for wind and fire when you file a claim after a Santa Ana event. Without it, you may face a denied or reduced claim. A written quote that lists the wind-load rating, fastener pattern, and Class A underlayment gives you evidence the adjuster accepts. We provide this documentation on every job. Call (805) 309-3314 if you have an existing roof and want to document compliance.
Yes, in most cases we can match the original flat concrete tile from the 1980s subdivisions off Kanan Road. We keep matching tile stock on hand for these profiles because cracked tiles are so common after windstorms. If the tile itself has failed structurally, we’ll tell you honestly and quote a replacement only if it’s actually needed. Call (805) 309-3314 and we’ll take a look.
