How Boral Products Fail – and How We Fix Them

Boral tile is dense and durable, but it’s not invincible. In San Francisco’s fog-and-salt air, we see the same handful of failure modes repeat across neighborhoods. Here’s what actually happens on Boral roofs here and how we address each one:

• Cracked or broken individual tiles from foot traffic or impact. Boral’s flat concrete profiles, like the Boral Milano or Verona lines, hold up well to wind but crack when someone walks the wrong ridge or a branch drops from a Monterey cypress. We replace the broken tile, matching color and profile from our local suppliers in San Francisco. One broken tile almost never means a new roof.
• Underlayment failure beneath the tile, especially on older Sunset District homes. Boral tile can last 50 or 60 years, but the felt or synthetic underlayment beneath it typically lasts 20 to 30. When that layer degrades, water gets under the tile and shows up as ceiling stains even though the tile itself looks fine. We lift the tile, replace the underlayment in the affected area, and reset the tile. This is the source of most Boral “leaks” in San Francisco.
• Valley metal corrosion from salt air and fog drip. Boral roofs in the Outer Richmond and Sea Cliff sit in marine air year-round. Galvanized valley metal eventually rusts through, and water follows the valley line straight into the roof deck. We replace rusted valleys with heavier-gauge metal and proper underlayment, then re-bed the Boral tile edges.
• Flashing separation at sidewalls and chimneys. San Francisco’s Victorians and Edwardians settle over time. That movement pulls step flashing away from stucco or brick, and on a Boral roof the gap hides beneath the tile edge. We inspect flashing on every Boral leak call, because it’s the second most common leak source after underlayment. The fix is new flashing, properly lapped, sealed, and tested.
• Hip and ridge tile that works loose in wind. Boral ridge pieces are mortar-set, and San Francisco’s winter storm winds work the mortar loose over years. A loose ridge tile is a safety issue as much as a leak issue. We re-mortar or mechanically fasten the ridge line using Boral-matched pieces so the line holds through next season’s storms.

Our Boral Roof Repair Process

Here’s how a Boral job runs with us, from the first call to final cleanup:

1. 1
   You call (831) 318-8819. A live person answers. We schedule a time, and our technician shows up inside the promised window, in uniform, background-checked.
2. 2
   We diagnose on the roof. We walk the tile field, check valleys, flashing, underlayment, and ridge lines. We don’t guess from the ground.
3. 3
   You get a written price. Before any work starts, we hand you the number on paper. It doesn’t move at the door.
4. 4
   We make the repair. For tile replacement, we use Boral or Boral-compatible tile matched to your profile and color. For flashing or valleys, we use gauge-appropriate metal. We don’t use aftermarket parts that compromise the roof’s integrity.
5. 5
   We test the repair. If water was the issue, we run water on the repaired area to confirm the leak is dead before we pack up.
6. 6
   We clean up and hand you the guarantee. Every Boral repair is covered in writing for one full year. If it fails within that year, we come back at no charge.
