Trusted Roofing Company for Thousand Oaks Homeowners
Finding a roofer in Thousand Oaks usually means choosing between a name you vaguely recognize and a truck you’ve never seen before. That’s the part most companies gloss over: you’re letting a stranger climb onto your home, and you don’t know who they are until they’re already in your driveway. Mercer Roofing Co Thousand Oaks does this differently. Before any technician arrives, you get their name and photo. At your door, they present a photo ID badge. They’re background-checked, uniformed, and held to the Threshold Verified standard. Grant Whitlock leads our Thousand Oaks team, and every job starts with a written price. Call (805) 309-3314 for a free roof estimate.
Roofing Contractor
Roofing Contractor is the licensed professional who handles everything above the decking: shingles, flashing, underlayment, vents, and the structural details that keep water outside where it belongs. In Thousand Oaks, most homeowners call a contractor when leaks appear, when a roof passes the 20-year mark, or when a buyer’s inspection flags problems before closing. Mercer Roofing Co Thousand Oaks covers it all, from single shingle replacements to full tear-offs and re-roofs, with a written price before any work starts. Typical repair visits run $350 to $800; re-roofs on a standard Thousand Oaks single-story run $12,000 to $22,000 depending on square footage and shingle choice.
When to Call a Contractor
You don’t need a full re-roof to justify a contractor’s visit. Cracked tiles after a windstorm, lifted flashing near the chimney, or water stains on the ceiling after a heavy rain are all reasons to have someone look sooner rather than later. Small fixes stop bigger problems, and our repairs come with a 365-Day Done Right Promise in writing.
What Our Contractor Service Includes
Every visit includes an inspection of the problem area, photos of the damage, and a written quote showing parts and labor as separate lines. No changes to the price once work begins, no surprises on the invoice. Your technician’s name and photo are sent before arrival.
Styles & brands we work with





Roof Inspection
Roof Inspection is a systematic look at every surface, seam, and penetration on your roof to find problems before they leak or worsen. In Thousand Oaks, where summer heat bakes shingles and winter rain tests flashing, an annual inspection catches small failures early. Mercer Roofing Co Thousand Oaks performs inspections for homeowners preparing to sell, buyers in escrow, and anyone who hasn’t looked at their roof in a few years. A standard residential inspection runs $195 to $350, and the fee is credited toward any repair work you approve within 30 days.
Inspection Reports That Make Sense
We give you photos of everything we find, annotated so you can see exactly what’s happening on your roof. The written report separates urgent items from watch-list items, so you know what needs attention now and what can wait. No vague language, no pressure.
Buyer and Seller Inspections
Real estate deals in Thousand Oaks often hinge on roof condition. We provide the documentation listing agents, buyers, and sellers need to negotiate repairs or price adjustments. Our report is dated, photographed, and written in plain English that everyone at the closing table can understand.
Commercial Roofing
Commercial Roofing covers flat and low-slope roofs on offices, retail spaces, warehouses, and multi-unit buildings across Thousand Oaks. These systems differ from residential shingle roofs: they often use membrane materials like TPO or EPDM, and they demand a different set of flashing and drainage details. Mercer Roofing Co Thousand Oaks handles inspections, repairs, coatings, and replacements for commercial properties, with pricing that starts around $800 for targeted repairs and runs $8 to $15 per square foot for full membrane replacement depending on material and access.
Flat Roof Repair and Coatings
Ponding water and UV exposure break down flat roofs faster than slope roofs. We identify compromised seams, replace damaged membrane sections, and apply reflective roof coatings that extend the life of a commercial roof by years. In Thousand Oaks’s dry heat, a white coating can cut surface temperatures dramatically and reduce cooling costs.
Minimized Disruption for Businesses
We schedule work around your operating hours when possible, and our written pricing means no change orders surprise your bookkeeper. Every commercial visit includes the same Threshold Verified technician standard: background-checked, badged, and in uniform, with their name and photo sent in advance.
Metal Roof Installation
Metal Roof Installation is the process of installing standing seam panels, metal shingles, or metal tiles as a long-wear alternative to asphalt. In Thousand Oaks, where fire risk is a real concern, metal’s non-combustible surface and 40-to-60-year lifespan make it an increasingly common choice. Mercer Roofing Co Thousand Oaks installs metal roofing over new construction and as a re-roof, with pricing that typically runs $18 to $28 per square foot installed. That’s higher than asphalt upfront, but the lifespan and reduced maintenance change the math over two decades.
Standing Seam vs. Metal Shingles
Standing seam panels give a clean, modern look with hidden fasteners and excellent water shedding. Metal shingles mimic the appearance of slate, tile, or asphalt while carrying metal’s durability. We walk you through both options, with samples, before you commit to anything.
Fire-Safety Considerations
Thousand Oaks sits in a high-fire-risk zone, and many homeowners in areas like Lynn Ranch and the hills above Westlake Boulevard are looking for roofing that won’t ignite from ember exposure. If you’re just over the border, our Roofing Company - Westlake Village team handles the same metal and fire-rated installations. Metal’s Class A fire rating is a significant factor, and we can discuss how it fits with your home’s overall defensible space plan. Installation involves heights and heavy panels; this is work for trained professionals, and our crews are equipped and experienced.
Residential Roofing
Residential Roofing is everything a single-family home in Thousand Oaks needs to stay dry: repairs, re-roofs, new construction roofing, and the ongoing inspections that protect the biggest investment most people ever make. We also serve nearby communities through our Oak Park Roofing Company location, using the same materials and standards. We work on the styles common throughout Thousand Oaks, from Spanish tile in Newbury Park to asphalt shingle in the Conejo Valley tract homes and composite shake in the gated communities off Lynn Road. A full residential re-roof typically runs $12,000 to $22,000; targeted repairs usually fall between $350 and $800.
Shingle, Tile, and Shake Replacement
Your home’s style dictates the roofing material, but your budget and long-term plans should influence the choice. We install asphalt shingles from GAF and Owens Corning, and we repair and replace concrete and clay tile without disturbing the surrounding courses. For homes with composite shake, we match existing profiles so repairs blend invisibly.
Re-Roof vs. Repair Decisions
A roof with five more years of life rarely needs a full re-roof, and we’ll tell you that plainly. Our written inspections separate “fix this now” from “plan for this later,” and we never recommend a re-roof when a targeted repair solves the problem. That’s part of the Done Right Promise: we make recommendations we’d make on our own homes.
Roof Maintenance
Roof Maintenance is the routine care that keeps your roof performing: clearing debris, checking flashing and seals, touching up problem areas, and documenting condition over time. In Thousand Oaks, where oak trees drop leaves onto valley roofs and Santa Ana winds scour exposed ridgelines, maintenance prevents the slow failures that turn into $3,000 repairs. Mercer Roofing Co Thousand Oaks offers annual maintenance agreements starting at $395 per visit, which include a full inspection, minor repairs, and a written condition report. Homeowners near the western edge of our service area can also book through our Agoura Hills Roofing Company office.
Seasonal Maintenance Schedule
We recommend a maintenance visit each fall, before the rainy season, to clear valleys and gutters and verify that flashings are sound. A spring visit addresses any weather damage from winter storms and checks seals that expand and contract through temperature swings. Two visits a year keep most Thousand Oaks roofs trouble-free.
Maintenance That Prevents Leaks
Most leaks start at penetrations: vents, chimneys, skylights, and pipe boots. A maintenance visit checks every one of these, reseals where needed, and documents the work with photos. The report becomes a record of your roof’s health that helps when you eventually sell.
Roof Coating
Roof Coating is a liquid-applied membrane brushed or sprayed over an existing roof to extend its life, reflect heat, and seal small cracks. It’s most common on flat and low-slope roofs, and in Thousand Oaks, where summer sun beats down for months, a reflective coating can lower roof surface temperatures by 50 degrees or more. At Mercer Roofing Co Thousand Oaks, coating applications typically run $2.50 to $5 per square foot, depending on the product system and the condition of the existing roof.
When Coating Makes Sense
A coating works best on a roof with sound decking but aging membranes or worn surfaces. It’s not a fix for structural problems, and we’ll tell you if yours disqualifies. When it fits, a coating can add 10 to 15 years of service at a fraction of replacement cost.
Coating Product Systems
We apply acrylic and silicone coating systems from recognized manufacturers, matched to your roof’s material and slope. Silicone handles ponding water better; acrylic offers strong reflectivity at a lower price. The written estimate shows which system we recommend and why.
Free Roof Estimate
Free Roof Estimate is a no-obligation site visit where we inspect your roof and give you a written price for the work that’s actually needed. It’s free, it’s specific, and nothing starts until you approve the numbers in writing. Mercer Roofing Co Thousand Oaks provides this on every job, from minor repairs to full re-roofs, because a price you can read is a price you can trust. Call (805) 309-3314 to schedule yours.
What the Estimate Includes
You get a written quote showing materials, labor, and any disposal or permit fees as separate line items. No ranges, no “we’ll see when we get up there.” The estimate is the price. If anything changes during the work, we stop and get your written approval before proceeding.
What to Have Ready
You don’t need anything ready. We’ll walk the roof, take photos, and answer your questions while we’re there. If you have a specific concern, like a stain on the ceiling or a tile you spotted in the yard, point us to it and we’ll start there.

AfterBrands We Service
We install and repair asphalt shingle roofing from GAF, and our crews are trained on the manufacturer’s installation specifications. GAF’s Timberline line is popular in Thousand Oaks for its wind ratings, which matter in the Santa Ana corridors. We also work extensively with Owens Corning products, particularly their Duration shingle line, which holds up well under the Conejo Valley’s intense summer UV exposure.
For concrete and clay tile homes, we service and match a range of profiles, including those commonly found in Newbury Park and the older tracts near Thousand Oaks Boulevard. Boral tile is a frequent match on custom homes in the hills, and we can source exact profiles when a few cracked tiles need replacement without disturbing the rest of the roof. Whether you have GAF, Owens Corning, Boral, or any other make, we can inspect it, repair it, and give you a straight answer about what it needs.
Signs You Need a Pro Right Now
- Water stains on the ceiling or walls. A stain means water is already inside your home, and it’s traveling from a breach in your roof. The longer it waits, the more decking and insulation get damaged, and a $400 repair becomes a $3,000 one.
- Curling, cracked, or missing shingles. Exposed underlayment or decking invites water in during the next rain. With Santa Ana winds, a missing shingle can also become a projectile that damages neighboring homes.
- Granules in your gutters or downspouts. Asphalt shingles shed granules as they age, and a heavy accumulation means the shingles are losing their protective surface. This is often the first visible sign that a roof is entering its final years.
- Daylight visible through the roof boards. If you can see light from inside your attic during the day, you have openings that will let water in. It’s a direct sign that repairs are overdue, and it’s often found during a pre-sale inspection.
- Loose or lifted flashing. Flashing is the metal that seals chimneys, skylights, and roof valleys. When it lifts or separates, water gets funneled straight into the structure. It’s one of the most common leak sources we find in Thousand Oaks homes.

How Much Does Roofing Company Cost in Thousand Oaks?
A typical roof repair in Thousand Oaks runs $350 to $800, while a full re-roof on a standard home runs $12,000 to $22,000. The spread depends on roof size, pitch, material, and how many layers need to come off first. Steep roofs, tile roofs, and jobs with flashing replacements push toward the higher end. A roof inspection costs $195 to $350, credited toward repairs you approve within 30 days. Roof coatings run $2.50 to $5 per square foot on flat or low-slope roofs.
What drives the price is mostly material and access. Asphalt shingles from GAF or Owens Corning are the most affordable; metal and tile run higher. A two-story home with a steep pitch takes more labor and safety equipment. To avoid overpaying, get a written quote that separates line items, and don’t accept verbal estimates. Our free estimate includes photos, a written scope of work, and a fixed price. Call (805) 309-3314 to schedule yours.
