Why Mercer Roofing Co Thousand Oaks Is Camarillo’s Preferred Roof Installation Company
Camarillo homeowners keep our number for one reason: we treat your home like the place you sleep, not a worksite. Every technician who steps onto your Camarillo property is background-checked, identity-verified, and arrives in a clean, marked uniform with a photo ID badge. Before the visit, you get the technician’s name and photo sent to you. That’s the Threshold Verified standard, and it’s non-negotiable on every job we run.
We’re part of the Threshold Group family, founded in 2000. Each location is independently owned and operated, and our Camarillo crews are held to the same written guarantees and vetting standards as every Mercer location. Grant Whitlock leads the team, and he’s the reason we put prices in writing before any work starts. No estimates that drift once the roof is open. No surprises on the invoice.
Our Roof Installation team has replaced roofs on 1960s ranch homes in Camarillo Heights, on 1980s composition roofs in Mission Oaks, and on newer Springville homes where the original builder-grade shingles gave out early. The pattern is consistent: the surface looks tired but intact, and the real damage is underneath.
Styles & brands we work with





Roof Ventilation in Camarillo
Roof ventilation in Camarillo matters more than homeowners expect, because the strong sun heats attic air well past 130 degrees in summer, and that trapped heat bakes shingles from below and shortens their life. Ventilation is the system of intake and exhaust that moves air through the attic: ridge vents, soffit vents, gable vents, or a combination. When a Camarillo roof goes on without balanced ventilation, the shingle warranty can be voided, and the decking warps or rots from condensation.
On a full roof installation in Camarillo, ventilation corrections typically run $600 to $1,900 depending on what’s already in place. If the home has no ridge vent and the soffits are solid, the cost runs higher because we’re cutting new openings and installing baffles.
Signs Your Camarillo Attic Needs Ventilation Work
If your upstairs rooms run hot in August or you see condensation on the underside of the roof sheathing in winter, the attic isn’t moving air. We check ventilation on every roof installation estimate in Camarillo, not as an add-on, but because a new roof on a suffocating attic fails early.
Ventilation and Santa Ana Winds
One Camarillo-specific note: ridge vents installed without proper wind baffles can let wind-driven rain in during a Santa Ana event. We use wind-rated ridge vent products and seal the ends properly, because the same wind that lifts shingles will push water sideways through a poorly flashed vent.
Roof Flashing Installation in Camarillo
Roof flashing installation in Camarillo is where most leaks actually begin, especially on 1980s-era composition roofs where the original valley metal and pipe collars have corroded or pulled loose. Flashing is the metal, usually galvanized steel or aluminum, that seals the joints where the roof meets a wall, chimney, skylight, or valley. When wind-driven rain hits those intersections, a failing flashing lets water in even if every shingle is sound.
Flashing replacement as part of a Camarillo roof installation typically runs $800 to $2,400 depending on how many valleys, pipes, and wall intersections the roof has. We replace all flashing during a full tear-off, never reuse the old metal, and we use corrosion-resistant materials suited to Camarillo’s coastal air.
Valley Flashing in Camarillo Homes
Many 1950s through 1980s Camarillo homes used lightweight, thin valley metal that corrodes at the seams. We install heavy-gauge, pre-finished valley metal and weave the shingles or tile through it properly. The difference is visible the first time the Santa Anas kick up and rain goes sideways.
Pipe and Chimney Flashing
Pipe collars dry out and crack in the Camarillo sun, and the old lead flashings on chimneys in the older Camarillo Heights homes are often past saving. We replace them and use a modern self-sealing collar or a soldered copper pan where needed.
Trusted Brands We Service in Camarillo
We install and repair roofing systems from GAF, CertainTeed, Owens Corning, and Boral, among others. For Camarillo specifically, we stock GAF Timberline HDZ and CertainTeed Landmark shingles locally, which keeps turnaround short when you’re ready to schedule. For the Spanish-inspired and ranch homes that dominate Camarillo’s older neighborhoods, Boral concrete tile and CertainTeed’s Presidential Shake give the right look without the maintenance of the original wood shake. We’ll help you match the existing profile so your Camarillo home keeps its character.
Common Roof Installation Problems We See in Camarillo Homes
- Torn felt underlayment beneath intact concrete tile. In Camarillo Heights, many original 1960s wood shake roofs were replaced with lightweight concrete tile years ago, but the felt underneath was never changed. Santa Ana wind uplift reaches under the tile, tears the old felt, and water finds the decking. The tile looks fine from the street.
- Wind-lifted shingles at eaves and rakes on original asphalt roofs. Older Camarillo homes often have nailing patterns that don’t meet current wind standards and no starter strip at the edges. The first strong fall wind peels shingles back at the eaves and rakes before the field of the roof shows any wear.
- Improper flashing at valleys and penetrations on 1980s homes. Mission Oaks and similar 1980s tracts used thin valley metal and rubber pipe collars that age poorly in the sun. Wind-driven rain pushes water through at those intersections, and the leaks show up on the ceiling far from the actual roof failure.
- Dried-out decking under the surface. On tear-offs across Camarillo, we often find the plywood or OSB decking has dried, delaminated, or rotted at the edges from years of small, slow leaks. We quote decking replacement by the sheet, in writing, so the change order doesn’t ambush you.

FAQs About Roof Installation in Camarillo
The tile isn’t the waterproof layer; the felt underlayment beneath it is, and on many original 1960s Camarillo Heights homes that felt is fifty years old. Santa Ana wind uplift gets under the tile edges, tears the brittle felt, and water seeps through to the decking while the tile above looks perfectly intact from the curb. The fix is a full tear-off down to the decking, not a patch. Call (805) 309-3314 and we’ll show you photos of what we find before we quote anything.
We work through the season but sequence the job around wind forecasts. Tear-off happens only when we can re-cover the exposed decking the same day, and we stage materials so nothing loose is left on the roof overnight. If winds are forecast over 30 mph, we hold the tear-off and reschedule. It’s slower, but it’s how you keep a Camarillo home dry mid-job.
Yes, Camarillo requires a permit for roof installation, and a full tear-off triggers current code requirements for underlayment, fastening patterns, and in some cases ventilation. That often means upgrading from the original nailing schedule to a 6-nail pattern, adding a starter strip, and bringing the attic ventilation into balance. We pull the permit, schedule the inspection, and the written estimate includes those code-driven items.
For most Camarillo homes we recommend architectural composition shingles with a 130 mph wind rating, installed with a 6-nail pattern and a high-temp underlayment. GAF Timberline HDZ and CertainTeed Landmark both perform well in Camarillo’s sun. Boral concrete tile is the right choice if you want the Spanish or ranch look and your structure can carry the weight, but the underlayment matters as much as the tile itself.
We write a per-sheet decking allowance into the contract before we start, so when we find rot or delamination under the old roof, you already know the cost. If the damage exceeds the allowance, we stop, show you photos of exactly what we found, and get your written approval on the change before we touch it. No one on your roof ever works from a surprise. Call (805) 309-3314 for an exact quote; estimates are free.
What Opens Up an Older Camarillo Roof
Opening up a 1960s ranch in Camarillo Heights or a 1980s tract home in Mission Oaks turns up the same three things, again and again: original felt underlayment that tears like paper, nailing patterns that wouldn’t pass today’s wind code, and flashing at the valleys and penetrations that gave out years ago. When the Santa Anas blow, the wind finds every one of those failures. That’s why our process starts with an inspection, not a bid. We write decking allowances, flashing replacement, ventilation corrections, and code upgrades into the contract before we tear off a single shingle. Then, if we find something outside the allowance, we price it and get your written approval before we proceed.
On a 1960s ranch in Camarillo Heights, we removed the original wood shake roof to find torn felt underlayment and dried-out decking edges. We replaced the decking, installed a high-temp ice and water shield as the underlayment, and installed GAF architectural shingles with a 130 mph wind rating using a 6-nail pattern on each shingle. That roof will hold through Santa Ana season after Santa Ana season, and the homeowner knew every dollar before we drove the first nail.
This page explains how Camarillo’s unique combination of Santa Ana winds, strong sun, and aging 1950s through 1990s housing stock drives specific roof installation failures and fixes, so you know exactly what our crew will find and how we’ll handle it before we tear off a single shingle. Call (805) 309-3314 to schedule your free estimate. A live person answers, and we’ll send the technician’s name and photo before the visit.
