Boral Roof Repair in Woodland Hills: What to Know First
We provide independent Boral roof repair in Woodland Hills with most jobs completed in one visit. A straightforward Boral shingle replacement or flashing repair typically runs $350 to $800, while more involved valley or underlayment work lands between $900 and $1,900 depending on how much decking needs attention. Nobody gets a final number until we’ve looked at your roof in person, but you will have a written price before any work starts. If you own a Boral roof in Woodland Hills and you’ve spotted a leak, a lifted shingle, or granules collecting in your gutters, call (341) 217-2677. We’ll send a technician whose name and photo you’ll have before they ring the bell.
Key Takeaways:
- We are an independent Boral service provider, not an authorized Boral dealer or warranty center.
- Every repair gets a written price upfront and a written 365-Day Done Right Promise included.
- We work on Boral’s clay and concrete tile profiles as well as Boral’s discontinued composite and asphalt lines.
- Our techs carry photo ID badges and arrive in marked uniforms. You’ll know who’s coming before they knock.
How Boral Products Fail – and How We Fix Them
Boral built a strong name on clay and concrete tile, and plenty of Woodland Hills homes still carry those roofs. But no roof is maintenance-free forever, and Boral products have their own particular failure patterns. Here’s what we see most often on Boral jobs across Woodland Hills.
- Cracked or fractured Boral concrete tile along eave edges. Boral’s concrete tiles are dense and durable, but the first row at the eave takes the brunt of wind-driven rain and occasional ladder or gutter-cleaner contact. A cracked tile there lets water behind the field of tile. We remove the damaged tile, inspect the underlayment beneath it, replace any compromised section, and set a matching replacement tile. If we cannot source an exact match for an older Boral profile, we will tell you before we touch anything.
- Flashing failures at valleys on Boral clay tile roofs. Woodland Hills gets real winter rain, and valley flashing on clay tile roofs does the hardest work on the house. Over time, the metal flexes from heat and moisture, sealant cracks, and water finds the seam. We cut back the old flashing, inspect the valley substrate, and install new corrosion-resistant metal with proper overlap. This is not a caulk-over-it fix. Done right, it should last decades.
- Underlayment deterioration under Boral tile in the Warner Center corridor. The summer heat in Woodland Hills, especially up around Warner Center, bakes roof decks. Boral tile can look fine from the curb while the underlayment underneath has dried and split. When we lift tile for a repair, we always check what is underneath. If the underlayment is failing, we replace that section before resetting the tile. Skipping this step is how you get a “fixed” leak that comes back in October.
- Discontinued Boral composite or asphalt shingle lines with no OEM match. Boral’s composite and asphalt product lines were discontinued years ago, and OEM replacements are effectively gone from distribution. Owners of those roofs need an honest conversation about quality aftermarket options that match the profile and perform well under Southern California sun. We will show you the closest available match and explain the trade-off before you approve anything.
- Cracked vent boot collars on Boral tile roofs. The rubber or metal collar around plumbing vent pipes eventually dries and splits, and that leak often gets blamed on the tile, which confuses everyone. On a Boral job, we pull the surrounding tile carefully, replace the boot and collar, reset the tile, and check the seal. It’s a modest repair that stops a surprising amount of water.
Styles & brands we work with






Our Boral Roof Repair Process
- 1
You call, a person answers. A live person picks up at (341) 217-2677, day or night. We ask about what you’re seeing, schedule a visit, and send you the technician’s name and photo before they arrive.
- 2
The technician arrives and badges in. Every Mercer technician presents a photo ID at the door. That is the Threshold Verified standard, and it is non-negotiable on every visit.
- 3
We inspect the roof and find the actual cause. We walk the roof, check the tile or shingle condition, inspect flashing, valleys, vent boots, and the underlayment where it’s exposed. Sometimes the leak is two feet from where the stain shows on the ceiling.
- 4
You get a written price before any work starts. We write down what’s wrong, what we’ll do, what materials we’ll use, and what it costs. If we need a quality aftermarket part because Boral no longer manufactures the original, we say so in writing.
- 5
We do the repair and test it. We make the repair, check surrounding areas for hidden damage, and run water where it makes sense to confirm the fix holds.
- 6
You get our 365-Day Done Right Promise in writing. If the repair fails within a year, we come back and make it right at no additional charge. That’s included with every job, every time.

AfterWhat Boral Roof Repair Costs in Woodland Hills
Boral roofs vary by profile, age, and what is underneath the tile, so here are real ranges for the Boral repair scenarios we handle most often in Woodland Hills:
- Single cracked concrete or clay tile replacement: $300 to $550
- Vent boot replacement on a Boral tile roof: $350 to $600
- Flashing repair at a valley or chimney on Boral tile: $500 to $1,100
- Sectional underlayment replacement beneath Boral tile (per 100 sq ft): $700 to $1,400
- Boral composite/asphalt shingle replacement with aftermarket match (small section): $450 to $900
- Repairs requiring extensive decking replacement beneath Boral tile: $1,200 to $2,500+
What moves the price is usually the condition of what sits underneath the tile, roof pitch and access, and whether the tile profile is still manufactured. Steep roof or second-story work adds labor. If the tile is fine but the underlayment is gone, the repair is bigger than a tile swap, and it should be, because otherwise the leak comes back. Call (341) 217-2677 to schedule a free estimate. You’ll have a written price before anything is done.
Why Woodland Hills Homeowners Call Mercer Roofing Co Woodland Hills for Boral Work
Most roofers can nail a tile back down. Fewer can tell you why it failed and whether the underlayment below is still doing its job. Grant Whitlock grew up in Los Angeles and learned the trade through the construction technology program at Los Angeles Trade-Technical College, and he has been on Woodland Hills roofs for well over a decade now, including plenty of jobs up in the Warner Center corridor where the summer heat alone will tell you whether a flat section was installed correctly. He’ll tell you when a repair is enough and when it isn’t, and he’ll put it in writing before anyone picks up a nail gun.
We also service GAF, Owens Corning, and CertainTeed roofs, which means we’re not precious about one brand. If your Boral roof needs work, we’ll fix it. If it’s reached the point where replacement makes more sense than repeated repairs, we’ll say that plainly too, with options that fit the house and the budget. Every repair carries a written 365-Day Done Right Promise, and if the repair fails within that year, the second visit is free. A roof should be the last thing you worry about. Let’s make sure it is.
FAQs
Boral’s clay and concrete roof tile lines were largely transitioned to the Westlake Royal Building Products portfolio, and availability of exact-match profiles depends on the specific tile model. For older or discontinued Boral profiles, we source the closest quality match and walk you through the differences before anything is installed. Call (341) 217-2677 and we’ll check what’s available for your tile.
A repair done properly by an independent contractor generally does not void a manufacturer’s material warranty, but the warranty terms vary by product line and date of installation. We do not claim to be a Boral warranty center. We do, however, write down exactly what we’re doing and what materials we’re using, so you have a clear record for any warranty conversation you need to have.
Not always. Some Boral profiles from the 1990s and early 2000s are simply out of production, and age and UV exposure mean even an exact model match may look slightly different. We’ll bring samples, show you the best available match, and discuss options including reclaiming tiles from less visible areas of your own roof. You’ll approve the choice before we install it.
Most Boral roof repairs in Woodland Hills are completed same-day once we’re on site, assuming weather allows. We schedule based on urgency of active leaks, and a live person answers the phone 24/7 at (341) 217-2677 if you’re seeing water coming in. For an exact timeline, call and we’ll get you on the schedule.
Yes. Boral’s composite and asphalt shingle lines are discontinued, so OEM replacements generally are not available. We use quality aftermarket shingles that match the profile and hold up under Woodland Hills sun exposure, and we explain the materials choice clearly in your written quote before work begins.
