Boral Roofing Company in Torrance: What to Know First
Mercer Roofing Co Torrance is an independent Boral service provider, not a manufacturer-authorized dealer, and we repair and replace Boral roofing across Torrance every week. Most Boral roof repairs in Torrance run between $450 and $1,800 depending on the failure, and a straightforward repair is usually completed the same day we diagnose it. You will always receive a written price before any work begins. If you own a Boral roof and something is leaking, cracked, or lifting, call (424) 435-5428 and a live person will answer.

This page is for the Torrance homeowner who already knows Boral products are good roofing and wants to understand why they sometimes fail, what a fix should cost, and who to trust when it is time to repair or replace them.
How Boral Products Fail – and How We Fix Them
Boral makes concrete and clay tile, and a lot of Torrance homes wear it. The roofing itself is durable. What fails, in our experience, is almost always the system underneath or around it. Here is what we actually see on Boral roofs in Torrance:
- Boral concrete tile cracking at the watercourse. Concrete tile expands and contracts with temperature swings, and the marine layer in Torrance means roofs stay damp longer than they do inland. Over time, hairline cracks form along the water channels where water flows. These cracks do not always leak immediately, but they let moisture into the tile body, and eventually through. We identify the cracked tiles, source matching Boral profile replacements where available, and reset them so the watercourse lines up and drains clean.
- Broken tiles from foot traffic. Boral tile can handle decades of sun, but it does not forgive a misplaced boot. Satellite installers, pest control workers, and even a previous roofer’s helper crack tiles by stepping in the wrong spot. Once the tile is cracked, the underlayment takes on water and starts to rot, and the leak may not show up inside for months. We replace the broken tile and check the felt or synthetic underlayment beneath it. If the underlayment is compromised, patching the tile is not enough, and we say so plainly.
- Failed underlayment under Boral tile. This is the most expensive and least visible Boral failure in Torrance. The tile itself can look fine while the felt beneath it has broken down from years of trapped moisture, especially on low-slope sections near Del Amo Fashion Center where fog sits on the roof every morning. The symptom is a leak with no obvious broken tile above it. The fix is removing tile in the affected area, replacing the underlayment, and reinstalling the tile. We give the written price for this before we lift a single tile.
- Valley and flashing failures at Boral tile transitions. Boral tile intersections at valleys, chimneys, and walls rely on metal flashing, and that metal fails faster than the tile ever will. In Torrance, salt air accelerates corrosion on flashing joints near the coast. Water follows the corroded seam and runs under the tile. We replace with new metal, re-bed the tile edges, and make sure the overlap sheds water away from the seam, not into it.
- Boral tile slipping out of alignment. On older installations, tiles shift when nails corrode or when a nail was never seated properly during the original install. A skipped or slipped tile leaves a gap that exposes the underlayment and invites water. We reset the tile with the correct fastener for the tile profile and confirm the surrounding tiles are locked in place.
Styles & brands we work with






Our Boral Roofing Company Process
Every Boral job in Torrance follows the same steps, and you know the price before any of them start.
- 1
You call, we answer. A live person picks up. We ask what you are seeing: a stain, a drip, a cracked tile, granules in the gutter. We schedule a visit and send you the name and photo of the technician coming to your door.
- 2
We diagnose without guessing. Grant Whitlock learned to read a roof the way a doctor reads an X-ray at Los Angeles Trade-Technical College, and that methodical approach is the standard on every Mercer job. We walk the roof points, check the flashings, and identify the actual failure path, not just the wet spot.
- 3
You get a written price before work starts. We explain what we found, what we recommend, and what it costs. We stay with the same number at invoicing.
- 4
We repair with the right parts. For Boral tiles, we source matching or compatible profile tiles when available and use quality aftermarket flashing and underlayment where the original spec is no longer manufactured. We never install a mismatched tile without telling you first and showing you the difference.
- 5
We test the repair. We run water across the repaired area, not just around it, and we watch the underside for any sign of moisture where we can access it.
- 6
You get the 365-Day Done Right Promise in writing. If it is not right within a year, we make it right. Every repair also includes a written guarantee and a free second visit if the repair fails.

AfterWhat Boral Roofing Company Costs in Torrance
Boral tile work does not have to be a mystery, and we would rather give you a real number than a vague range that stretches three thousand dollars wide. Here is what Boral owners in Torrance typically pay:
- Single cracked or broken Boral tile replacement: $450 to $650, depending on roof pitch, access, and whether we have the matching tile profile in inventory or need to source it.
- Valley or flashing repair at a Boral tile intersection: $800 to $1,400, depending on how many linear feet of metal need removal and replacement.
- Spot underlayment replacement under Boral tile (small area): $1,200 to $1,800, including removing, labeling, and reinstalling the existing tile.
- Full Boral tile roof repair involving multiple valleys, underlayment replacement, and tile reset: $2,500 to $6,000, quoted as a written, line-item price before we begin.
What moves the price is access, roof pitch, how many tiles need to come off, and whether underlying decking has rot. We show you the number before any work, and it does not change unless we find something we could not have seen from the surface, in which case we show you a photo and a new written price before proceeding. Call (424) 435-5428 for a free estimate on your Boral roof.
Why Torrance Homeowners Call Mercer Roofing Co Torrance for Boral Work
The roof is only doing its job when you never have to think about it. When it stops doing that job, you want someone showing up who treats your home like a place to be protected, not just a job site. Every Mercer technician is background-checked, identity-verified, and badged. Before the visit, you get the technician’s name and photo. At the door, they present a photo ID. The price is in writing before work starts, the guarantee is in writing when the job is done, and a live person answers the phone 24/7. We know Boral tile because we work on it constantly in Torrance, and we also service GAF, Owens Corning, and CertainTeed roofs when a repair spans more than one roofing type.
FAQs
No. As an independent Boral service provider, Mercer Roofing Co Torrance does not represent or act on behalf of Boral, and our repairs do not void the manufacturer’s coverage. What can compromise a Boral warranty is failing to repair a known leak, because the water damage becomes a system failure, not a tile failure. That is why we document what we find and give you the written record of what we did.
In most cases, yes. Boral tile profiles and color blends can shift between production runs, and older tiles weather, so a brand-new tile next to a twenty-year-old tile may not match perfectly even when the model is the same. We tell you if we can source a true match, and if we cannot, we show you the closest compatible option before any work begins. Call (424) 435-5428 and we can identify what is on your roof from photos and tell you what is available.
Most single-tile and flashing repairs are scheduled within a day or two and completed the same day we diagnose them. Larger underlayment work depends on the size of the affected area and the weather window. We will give you a written schedule when we give you the written price.
It depends on the underlayment. If the underlayment is failing in multiple areas, replacing tile without addressing it just means you will chase leaks for years. If the underlayment is intact and the failure is isolated, a repair makes financial sense. We show you what we see, with photos, and give you both options with real numbers. Your call, based on the actual condition of your roof, not a guess.
No, unless we find damage we could not have seen from the surface inspection. If that happens, we stop, show you a photo, and give you a new written price before we continue. The number we quote on Tuesday is the number on the invoice when the job is done.
