How Boral Products Fail – and How We Fix Them

Boral makes a solid product, but San Diego’s combination of intense UV exposure, salt air near the coast, and temperature swings between inland valleys and the marine layer creates specific failure patterns. Here’s what we actually find on Boral jobs:

• Boral Concrete Tile (BoralTile line) – underlayment failure before tile failure. The tile itself can last 50 years, but the felt or synthetic underlayment beneath it breaks down decades sooner. In neighborhoods like Clairemont and Tierrasanta, we regularly see tiles that look fine from the street while the underlayment underneath has turned to dust. The fix is a tile lift-and-relay: we remove the tile, replace the underlayment, and reset the same tile if it’s still sound. You don’t need new tile just because the paper underneath gave out.
• Boral Steel Roofing (Boral Steel line) – fastener back-out at laps. Steel expands and contracts with San Diego’s inland heat swings, especially in places like Santee or El Cajon where summer afternoons hit triple digits. Over time, fasteners at panel laps can back out slightly, creating small gaps where wind-driven rain gets in. We re-secure laps with the correct fasteners and reseal with a urethane sealant rated for metal-on-metal contact.
• Boral Clay Tile (US Tile by Boral) – broken corners from foot traffic. Clay tile is brittle by design. When a previous contractor walked the roof without proper walk boards, or when a tree branch dropped onto a corner, you get cracked or spalled tile edges. Water then sits against the crack and works its way into the underlayment. We replace individual broken tiles when color match allows, or do a sectional replacement with a close-match blend when the original color is no longer manufactured.
• Ridge cap failures on Boral tile systems. The ridge cap mortar or cap nails are the most common leak point on any tile roof, Boral included. In San Diego’s dry season, mortar can shrink and crack away from the ridge beam. We remove the old cap, inspect the ridge board, and reset the cap with proper fastening and a flexible sealant that moves with the house.
• Boral Stone-coated Steel (Boral Steel line) – valley flashing corrosion near the coast. Homes in Ocean Beach, Pacific Beach, and La Jolla see salt-air corrosion on valley flashings years before anything else fails on the roof. The stone coating on the panels holds up well, but galvanized flashings at valleys and penetrations dissolve in salt air. We replace them with aluminum or stainless flashing and re-bed the valley, which typically adds 15 to 20 years of life to that section.

Our Boral Roofing Company Process

Every Boral job we do in San Diego follows the same six steps, whether it’s a two-hour repair or a full replacement. The Kingswell Way is simple: say the price before the work, show up in the window we gave, leave the place cleaner than we found it, put the guarantee in writing, and come back if it fails.

1. 1
   Call and diagnose. You call (619) 393-3877, a live person answers, and we schedule a time that actually works. Greg or a lead tech walks the roof and listens to what you’ve seen: stains, drips, missing tile, wind noise.
2. 2
   Written price before any work. We hand you a line-item written quote before anyone touches a ladder. No phone call later with “we found additional issues.” If we find hidden damage once the roof is open, we stop and talk to you first. The written price is the price.
3. 3
   Parts decision: OEM vs quality aftermarket. For Boral tile, we use genuine Boral tile when it’s available and color-stable. When the line is discontinued, we source close-match aftermarket tile from our San Diego suppliers and show you samples before we install. For underlayment and flashings, we use premium aftermarket products that meet or exceed Boral’s original spec.
4. 4
   The repair or replacement. We protect the work area, remove only what needs removing, and do the work the way the manufacturer’s installation manual specifies. On tile jobs, that means proper walk boards to protect the tile we’re not replacing. On metal, that means the right fasteners and sealants, not whatever is in the truck.
5. 5
   Test and inspect. We run water on the repaired area and check the underside where accessible. Then we walk the whole roof once more to make sure the problem is solved and nothing adjacent was disturbed.
6. 6
   Written guarantee before the crew leaves. You get the guarantee in your hand before the truck pulls away. If that repair fails inside the guarantee period, we come back and fix it at no charge. That’s the 365-Day Done Right Promise, and it’s written on every invoice.

What Boral Roofing Company Costs in San Diego

Here are realistic price ranges for common Boral jobs in San Diego, based on the work we’ve done across the county:

• Individual Boral tile replacement: $45 – $90 per tile, depending on access and whether we can match the existing color or need to blend.
• Tile lift-and-relay for underlayment replacement (sectional): $1,800 – $4,500 for a typical 300 – 600 square foot section, including underlayment and re-bedding the tile.
• Valley flashing replacement on Boral steel or tile: $600 – $1,500 per valley, depending on length and the flashing material required.
• Ridge cap re-bed and reset: $35 – $60 per linear foot.
• Full Boral tile roof replacement: $18,000 – $35,000 for a typical 1,800 – 2,400 square foot San Diego home, depending on tile profile, underlayment choice, and roof complexity.

What moves the price most is access: a two-story home in Mission Hills with a steep pitch costs more to work on than a single-story in Santee. Underlayment choice matters too, with synthetic underlayment running about 20 – 30% more than felt but lasting significantly longer. Call (619) 393-3877 for an exact quote on your roof. Estimates are free, and the written price is what you pay.

Why San Diego Homeowners Call Tilehurst Roofing San Diego for Boral Work

Most of our Boral customers came to us after another roofing company let them down. Maybe the crew never showed. Maybe the price changed at the door. Maybe the repair failed within a month and nobody answered the phone when they called back.

We’re part of the Kingswell family of roofing companies, founded in 2000, and every location operates under the Kingswell Guarantee: written price before any work, written guarantee on every repair, and a free second visit if the repair fails inside the guarantee period. Our techs are background-checked and uniformed, so you know exactly who is on your roof.
