This page is for San Francisco homeowners who own Boral tile roofs and need a roofing company that knows how that roof was built, how it fails in this climate, and how to fix it without voiding the manufacturer warranty. If you have cracked tiles, a leak near a valley, or tiles sliding out of place on a steep Nob Hill pitch, call (831) 228-3330. A live person answers, day or night.

How Boral Products Fail – and How We Fix Them

• Boral Concrete Tile (Standard Weight, San Francisco’s most common Boral line): The usual failure isn’t the tile itself. It’s the fasteners. On older San Francisco installations, galvanized nails were used instead of the now-standard stainless steel, and forty years of fog-driven moisture rusts those nails through. A tile that looks fine from the street may be hanging on by rust scale. Erik Lindgren has walked dozens of these roofs in the Outer Sunset and Richmond, and the pattern is predictable: nail heads dissolve first at flashings and roof-to-wall transitions. We remove the loose tiles, replace fasteners with stainless, and reseat the tile over fresh mortar where the original bed has crumbled.
• Boral Clay Tile (Mission and Spanish profiles): Clay tile in San Francisco takes a beating from falling tree debris and the salt air. The concrete tiles absorb impact better; clay shatters. We see this a lot under Monterey cypress and eucalyptus trees. One cracked clay barrel tile lets water onto the underlayment, and from there it travels sideways before it shows up as a ceiling stain two rooms away. Our fix: remove the cracked tile without disturbing neighbors, replace it with a matched Boral clay tile or a quality color-matched aftermarket equivalent, and replace any underlayment that has gone soft.
• Boral CedarLite and Shake-Style Concrete: These profile tiles collect more debris than flat tiles, which is a real problem in San Francisco’s wind. Leaves and pine needles wedge into the shake profile seams, hold moisture against the tile surface, and accelerate surface spalling. On a 1920s Edwardian in the Sunset District, we pulled enough debris out of shake-style tile seams to fill two contractor bags, and the underside of the tiles was soaking wet. The fix is part repair and part maintenance plan: we recommend an every-three-year debris clearing on CedarLite roofs near heavy tree cover.
• Boral Tile Underlayment Failure (all tile lines): The tile on a Boral roof can last 50 years, but the underlayment underneath commonly fails at year 20 to 25. In San Francisco, the combination of fog, salt, and dramatic temperature cycles between west-facing and north-facing slopes shortens underlayment life further. We see underlayment that has turned to shredded paper under tiles that still look brand new. When that happens, tiles come off carefully, new underlayment goes down, and the same tiles get reinstalled, which is both cheaper and more honest than selling a full replacement when the tile has decades left.
• Boral Tile Slippage on Steep San Francisco Pitches: San Francisco has hundreds of Victorians with roof pitches steeper than 8:12. Boral tile installations on these slopes require specific fastening patterns and hurricane clips, and some older installations didn’t include them. We get called out to Russian Hill and Pacific Heights for tiles that have slid down the roof and lodged against a gutter or skylight. The immediate fix is straightforward, but Erik always checks the whole slope before quoting, because where one tile slid, others are usually loose behind it.

Our Boral Roofing Company Process

1. 1
   You call, we listen. Tell us where the ceiling stain is, when you first noticed it, and whether you’ve had Boral work done before. We’ll ask for photos if you can safely take them; if not, we’ll see it ourselves.
2. 2
   Erik or a senior Boral-trained technician walks the roof. Every slope, every flashing point, every tile course. We’re looking for the failure mode, not just the failed tile.
3. 3
   You get a written price. In dollars. Before we move anything. It covers the tiles, fasteners, underlayment, mortar, disposal, and clean-up. A written price before a single shingle moves, that’s just how the job starts.
4. 4
   We do the work carefully. Shoe covers at the door, drop cloths through the hallway, and a tarp under the work area. If your dog needs to stay inside, we coordinate door schedules so the crew and the dog don’t surprise each other.
5. 5
   We test the repair. We water-test the area we fixed before we leave. If water still gets through, we’re not done.
6. 6
   Clean-up is photographed and verified. The roof deck, the walkway, the yard, all clear. We send you a photo of the completed clean-up before the crew pulls away.

What Boral Roofing Company Costs in San Francisco

Most Boral tile repairs in San Francisco fall into these ranges:

• Single cracked or broken tile replacement: $450 to $700, depending on access and whether the tile profile is still manufactured.
• Small area re-tile with underlayment patch (under 100 square feet): $1,200 to $2,800, depending on roof pitch and the condition of surrounding tiles.
• Boral valley repair with flashing replacement and re-tile: $1,800 to $3,500, depending on valley length and whether the underlayment under the valley has rotted.
• Full underlayment replacement on a Boral tile roof (keeping existing tile): $9 to $14 per square foot in San Francisco, driven by tear-off labor, disposal, and the fact that we hand-sort and clean every tile before reinstalling it.

The three things that move your price: roof access, tile availability, and what we find when we lift the first tile. You’ll never discover a change order after we start, because we walk the roof before we quote. Call (831) 228-3330 to schedule a free estimate with Erik or a Boral-trained technician.

Why San Francisco Homeowners Call Birchbark Roofing San Francisco for Boral Work

We are not a generalist roofer who occasionally works on tile. Erik Lindgren has spent over two decades working roofs up and down California, including thorough service across San Francisco’s older Victorian and Edwardian neighborhoods where Boral tile roofs are most common. The salt air and old wood sheathing in the Sunset District keep you honest, and honesty is what these roofs require.

Every Boral job we perform carries the 365-Day Done Right Promise: if it isn’t done right, we make it right. That guarantee is stamped on every job, not buried in a contract. We also work with GAF, Owens Corning, and CertainTeed products for repairs where a Boral tile isn’t the right fit or isn’t available, so you won’t be sold a product we happen to stock; you’ll get the product your roof needs. And we’re backed by the Cedarwell family of roofing companies, which has been holding local roofing businesses to a higher standard of care since 2000.
