Boral Roofing Company in Thousand Oaks: What to Know First
We repair and replace Boral roof tile systems throughout Thousand Oaks, and most jobs are diagnosed within one business day of your call. Boral concrete and clay tile is some of the most durable roofing material made, but that durability depends on what’s underneath it: the underlayment, the flashing, and the fasteners. Those wear out years before the tile itself does. If you own a Boral roof in Thousand Oaks, you’re likely dealing with a leak that has nothing to do with broken tile, which is exactly where our experience matters. Call (805) 309-3314 for a free estimate.
How Boral Products Fail – and How We Fix Them
Boral tile rarely fails on its own. What fails is the system around it. Here’s what we see most often on Thousand Oaks homes:
- Underlayment fatigue under Boral CedarLite and Barcelona profiles. These lighter-weight concrete tiles are popular in the Conejo Valley, and the tile itself can last fifty years or more. The underlayment beneath it, however, typically lasts twenty to thirty years, and when it breaks down, water finds the decking. Homeowners see a ceiling stain and assume a tile cracked. We lift the tile, show them the rotted felt, and replace the underlayment in sections without disturbing intact tile.
- Cracked Boral Villa flat tiles from foot traffic. The low-profile flat tile looks clean and modern, but it cracks more easily than a high-profile barrel tile when someone walks on it. In places like Lang Ranch where solar installers and satellite techs have been on the roof, we regularly find hairline cracks invisible from the ground. We bag and replace individual tiles, color-matched where possible.
- Failed flashing at roof-to-wall transitions on Boral Madrid installations. The Madrid profile has a pronounced channel that moves water fast, but only if the step flashing against the wall is still intact. Thousand Oaks gets hard, short rain bursts after long dry spells, and old flashing that has lifted slightly will channel water straight behind the stucco. We remove the lower tile courses and replace the flashing with new metal, then re-bed the tile.
- Bird strike and displaced tile after Santa Ana winds. High-profile Boral profiles, especially the one-piece barrel shapes, catch wind from the north in October and November. A single displaced tile exposes the batten and the underlayment to every storm that follows. We re-secure displaced tiles the same week in most cases, because a missing tile in Thousand Oaks in November usually becomes a leak by January.
- Efflorescence and freeze-thaw spalling on older Boral concrete tile. Concrete tile absorbs a little moisture, and in Thousand Oaks, night temperatures drop low enough in winter that moisture inside the tile expands. Older Boral installations, before newer denser mixes, can show surface spalling on north-facing slopes. It’s cosmetic until it isn’t. We inspect those slopes carefully on any roof we’re called out to, even if the leak is elsewhere.

Our Boral Roofing Company Process
Here’s how a typical Boral repair goes with us, start to finish:
- 1
You call, a person answers. You describe what you’re seeing: a stain, a drip, a tile you found in the yard. We book a diagnostic visit, and before our technician arrives, you get their name and photo by text.
- 2
We badge in and go up. The technician shows photo ID at the door, then does a full inspection: the visible tile, the underlayment below the trouble spot, the flashing, the valleys, and the ridge. We take photos of everything we find.
- 3
We show you what we found. You see the same photos the technician took. If it’s an underlayment failure, we show you the rotted felt. If it’s a cracked tile, we show you the crack. Nothing is done before you understand the problem and have a written price.
- 4
The fix. For tile replacement, we use OEM Boral tile where it’s available and matches, or a quality aftermarket equivalent when Boral has discontinued the color or profile. For underlayment, we use a modern synthetic underlayment rated for our climate. For flashing, new metal cut to fit the existing profile.
- 5
We water-test. Before we come down, the repair area is hosed and checked. If water moves where it’s supposed to, we clean up, walk you through the work, and hand you the written guarantee.
- 6
You’re covered for 365 days. Every repair includes the 365-Day Done Right Promise: if it’s not right within a year, we come back and make it right at no charge.

AfterWhat Boral Roofing Company Costs in Thousand Oaks
| Boral job type | Typical range in Thousand Oaks |
|---|---|
| Replace 1 – 3 cracked Boral tiles | $300 – $650 |
| Flashing repair at a roof-to-wall or chimney transition | $450 – $950 |
| Underlayment replacement, small section (up to 100 sq ft) | $1,200 – $2,400 |
| Full re-tile with Boral tile, including new underlayment | $18,000 – $38,000 depending on profile and roof complexity |
The big variable is usually what we find under the tile, not the tile itself. A cracked tile is a quick fix. Rotted underlayment under an entire roof slope is a bigger job, and Thousand Oaks homes with original underlayment from the 1990s are at that point now. We never start work without a written price, and the estimate you approve is the number on the invoice. Call (805) 309-3314 and we’ll come out, look, and give you the real number.
Why Thousand Oaks Homeowners Call Mercer Roofing Co Thousand Oaks for Boral Work
Most roofing companies in Thousand Oaks can replace a broken tile. What they can’t always do is tell you why it broke and whether the problem under it matters more. We work on enough Boral tile to know the difference between a cosmetic crack and a water path into your attic, and we’ll show you the photos to prove which one you have. Every technician who walks up your driveway is background-checked, identity-verified, and in a clean uniform with a photo ID badge. You’ll know the name and face of the person coming to your home before they arrive. And if you need a roof section rebuilt with a different manufacturer, we also work with GAF, Owens Corning, and CertainTeed shingles, so the answer is never “that’s not our product.”
FAQs
No. We are an independent Boral service provider in Thousand Oaks, not a factory-authorized installer. That means we’re free to recommend what’s actually best for your roof, whether that’s an OEM Boral tile, a quality aftermarket equivalent, or a repair that avoids new tile altogether.
In many cases, yes. Boral has made dozens of colors over the decades, and some have been discontinued. We’ll pull a sample from your roof and match it to what’s currently available. If we can’t get an exact match, we’ll tell you before we touch anything, and we can often blend a close shade so the repair disappears from the ground. Call (805) 309-3314 if you’re wondering about availability.
Most Boral product warranties apply to the tile itself, not to installation or repair work done later. That said, if your tile is still under warranty and shows a manufacturing defect, we’ll point that out and help you understand your options before selling you a repair. We’d rather you get what the manufacturer owes you.
A typical repair involving a few cracked tiles or a flashing replacement takes half a day from the time we arrive. Underlayment replacement can take a full day or more depending on how far the damage runs. We’ll give you a timeline in writing along with the price before any work starts.
We water-test every repair before we leave, and you’ll get a written 365-Day Done Right Promise with the job. If the repair fails within the year, we come back and make it right free of charge. A roof should protect you quietly. If you’re thinking about it, something’s wrong.
