Boral Roof Installation in Woodland Hills: What to Know First
Boral roof installation in Woodland Hills means working with a tile system that’s built for Southern California heat but demands a level of care on the deck that shingle roofs don’t. As an independent Boral service provider, Mercer Roofing Co Woodland Hills installs and services Boral roof systems across the area, with most full installations taking four to seven working days depending on roof complexity and pitch. You’ll get a written price before any work begins, and the number you see is the number you pay.
If you own a Boral roof or are considering one for your Woodland Hills home, this page covers how these systems fail, what we do differently during installation, and exactly what to expect on cost. Call (341) 217-2677 to schedule a free estimate. Grant Whitlock and our crew know Boral tile work from the deck up, and we’ll tell you straight what your roof needs and what it doesn’t.
How Boral Products Fail – and How We Fix Them
Boral makes a strong roof system, but no roof is immune to the Valley sun, Santa Ana winds, and the occasional heavy rain that hits Woodland Hills. Most Boral problems we see aren’t the tile itself; they’re what’s underneath or around it. Here are the five most common failure points we find on Boral roofs in this area and what we do about each one.
- Underlayment breakdown on older Boral installations. The tile on your roof can easily outlast the underlayment beneath it, especially on Boral’s concrete and clay lines installed in the 1990s and early 2000s. In Woodland Hills, the heat cycles bake underlayment until it becomes brittle and starts pulling away at the laps. We strip the old tile carefully, replace the underlayment with a high-grade synthetic suited for tile, and reset or replace the tile as needed. The tile often goes right back on.
- Broken or cracked tile from impact and thermal shock. Boral tile is dense and durable, but it can crack from falling tree limbs, foot traffic on the roof, or the sudden temperature swings we get when a hot Valley day drops into a cool night. Cracked tile lets water reach the underlayment. We replace damaged pieces individually when we can, matching the profile and color, and we always check the surrounding tiles for hairline fractures that haven’t opened up yet.
- Flashing failures at valleys, chimneys, and sidewalls. This is the number one leak source on Boral tile roofs in Woodland Hills, and it has nothing to do with the tile itself. Flashing metal gets thin over decades, the sealant dries out, and water finds a path behind the tile. On Boral jobs, we replace flashing with the correct gauge for tile profiles and re-seat the tile over it so the system sheds water the way it was designed to.
- Loose or displaced tile after wind events. Santa Ana winds can lift the edges of Boral tile and shift pieces out of position, especially on two-piece and flat-profile tile systems. When tiles shift, the interlocking waterproof channels break. We re-bed and re-point tile at hips and ridges, and replace any tile with cracked nail holes or broken interlock tabs. A shifted Boral tile is not a cosmetic issue; water will find it.
- Bird stop and eave closure deterioration. At the eaves, the bird stop and closure system that keeps pests out and tile aligned degrades over time under direct sun. We see this constantly on Boral’s lightweight concrete profiles in Woodland Hills. When we install or repair Boral roofs, we replace deteriorated bird stop with a durable metal or properly rated plastic option and secure the first course of tile so it sits correctly and won’t slide.

Our Boral Roof Installation Process
Here’s how a Boral roof installation goes when you work with us, step by step, so you know exactly what’s happening on your roof before it happens.
- 1
Initial call and site assessment. You reach a live person at (341) 217-2677. We schedule a visit, and you get the name and photo of the technician before they arrive. They’ll show up badged and in uniform.
- 2
Roof inspection and deck evaluation. We inspect the existing roof, check the decking condition, measure pitch and square footage, and review whatever existing underlayment and tile we’re working with. If it’s a re-roof over an older Boral system, we check for water damage at the deck level before recommending anything.
- 3
Written price and scope. You get a written line-item price before any work starts. It covers materials, labor, underlayment, flashing, tile, disposal, and any decking replacement we found during inspection. No change orders unless you approve something additional in writing.
- 4
Tear-off and deck preparation. We remove old roofing material down to the deck, repair or replace damaged decking, and install the correct underlayment for a Boral tile system. This step is where a lot of installers cut corners; we don’t.
- 5
Boral tile installation and flashing work. We install flashing at all penetrations, set the tile per Boral’s installation specifications and local building code, and finish with hip and ridge tile secured properly. Valley work gets special attention because that’s where Boral roofs in Woodland Hills leak first when installed wrong.
- 6
Final inspection, cleanup, and your written guarantee. We walk the roof, check every transition, clean up all debris, and hand you a written guarantee on the installation. If something’s not right within 365 days, we make it right. That’s the 365-Day Done Right Promise, in writing.

AfterWhat Boral Roof Installation Costs in Woodland Hills
Boral roof installation in Woodland Hills runs higher than a standard asphalt shingle job because the material is heavier, the labor is more specialized, and the underlayment requirements are stricter. Here are the ranges we typically see for common scenarios. These are rough numbers to give you a real starting point; your written estimate will pin it down exactly.
- Full Boral concrete tile installation on a 2,000 sq ft home: $18,000 – $28,000 depending on profile, deck condition, and roof complexity.
- Full Boral clay tile installation on a 2,000 sq ft home: $25,000 – $38,000. Clay is heavier and more expensive, and some Woodland Hills homes need additional structural review.
- Re-roof that includes new underlayment plus tile re-set (tile reused): $8,000 – $14,000 for a typical single-story home. This is common when the tile is still in good shape but the underlayment has failed.
- Tile repair and isolated replacement work: $400 – $1,200 depending on how many tiles and whether flashing is involved.
What moves the price: roof pitch, two-story access, tile profile (flat profile costs more to install than two-piece), deck repair, and whether you need structural upgrades for heavier tile. Call (341) 217-2677 for a free estimate with a written price. No surprises on the invoice, ever.
Why Woodland Hills Homeowners Call Mercer Roofing Co Woodland Hills for Boral Work
You want to know who’s walking onto your property. We send you the technician’s name and photo before the visit, and they arrive in a clean uniform with a photo ID badge in hand. Every Mercer Roofing technician is background-checked and identity-verified under the Threshold Verified standard, which each independently owned location is held to. That matters whether you’re home alone during the day or you’ve got kids in the house when the work starts.
Beyond who’s at your door, you get a written price before any work begins and a written guarantee on the installation, backed by the 365-Day Done Right Promise. If the work isn’t right within a year, we fix it. And when a Boral system isn’t the right fit or you want to compare, we install GAF, Owens Corning, and CertainTeed systems too. One honest conversation, not a sales pitch. Grant Whitlock grew up in Los Angeles and learned the trade through the construction technology program at Los Angeles Trade-Technical College before putting roofs on Woodland Hills homes for well over a decade, including plenty of jobs up in the Warner Center corridor where the summer heat alone tells you whether a tile roof was installed properly.
A roof should be the last thing you worry about. Let’s make sure it is.
FAQs
No. We are an independent Boral service provider, not an authorized or factory-affiliated installer. That independence means we recommend what’s best for your roof and your budget, not what a manufacturer program tells us to push. We install Boral systems correctly and then stand behind our own written guarantee.
Boral’s tile warranty covers the tile itself, not the installation. What matters for your long-term protection is that the installer follows Boral’s installation specifications and local code, which we do. The written guarantee we provide covers the workmanship on your installation for 365 days, and if something fails, we return and make it right at no charge. Call (341) 217-2677 to talk through your specific roof and warranty question.
Most full Boral roof installations in Woodland Hills take four to seven working days, depending on roof size, pitch, and how much deck work is needed. Weather rarely delays us in the Valley, but we’ll keep you posted daily on where things stand. You’ll have a written timeline before we start.
Often, yes. If the tile itself is still solid and the problem is failed underlayment, flashing, or a handful of broken tiles, a repair makes more sense than a full replacement. We’ll tell you straight if a repair is enough, and we’ll put that in writing along with the estimate. If it’s not enough, we’ll explain exactly why and show you what we found. Call (341) 217-2677 for an honest assessment.
Most structural roof replacements in Woodland Hills require a building permit through the Los Angeles Department of Building and Safety. We pull the permits, schedule the inspections, and make sure your new Boral roof passes. The permit cost is included in your written estimate, so you won’t get a surprise charge later.
