Boral Roof Inspection in San Francisco: What to Know First
Boral roof inspection in San Francisco typically runs $295 – $495 for a full written assessment, and we can usually get a technician to your property within three to five business days. We’re an independent Boral service provider – not affiliated with the manufacturer – so our reports tell you what’s actually happening on your roof, not what a warranty rep wants to hear. If you own a Boral concrete or clay tile roof in San Francisco, this page covers what we look for, what we find, and what it costs to make it right. Call (831) 318-8819 to schedule your inspection.
Key takeaways:
- Boral tile roofs in San Francisco fail differently than asphalt – we inspect for tile-specific issues, not generic wear.
- Most Boral roofs here need underlayment attention 15 – 20 years in, even when tiles look fine from the ground.
- Our inspections produce a written report with dollar ranges, so you know exactly where you stand before any work starts.
How Boral Products Fail – and How We Fix Them
Boral makes a few product lines that show up regularly on San Francisco homes, and each has its own failure signature. Here’s what we actually see when we walk these roofs:
- Boral Inspire concrete tile – cracked tile corners from foot traffic. San Francisco roofs get walked more than most: satellite installers, gutter cleaners, chimney sweeps. Boral Inspire tiles are strong, but the corners snap when weight lands between the water channels. We replace individual tiles with color-matched stock or quality aftermarket equivalents, and we document the pattern to identify traffic paths that need protection.
- Boral Mission clay tile – broken barrels from salt fog and temperature cycling. The Sunset and Richmond Districts get direct salt air exposure, and clay tile absorbs a little moisture. When fog rolls in overnight and sun hits mid-morning, that expansion cycle cracks barrels that were already weakened at the nail hole. We see this most on homes within half a mile of the ocean. Fix is simple: replace the cracked barrel and check the nail hole for rust that spread to the batten.
- Underlayment failure under Boral tile – the real problem nobody sees. Boral tile can last 50 years or more. The underlayment underneath usually can’t. In San Francisco’s wet winters, we find underlayment that’s dried out, split at the seams, or pulled away from the drip edge after 15 – 20 years. The tile looks fine from the curb, but water is already working its way into the decking. This is the single most common issue we find on Boral inspection jobs.
- Flashing failures at San Francisco roof junctions. Flat-to-pitch transitions, skylight curbs, and chimney bases on Boral roofs in older neighborhoods like Noe Valley or Glen Park often show original lead or galvanized flashing that has corroded. The salt air speeds it up. We replace flashing with modern materials and re-bed it under the tile so the water channel stays intact.
- Boral Shake look-alike tile – wind-driven rain getting under the laps. On exposed ridges and west-facing slopes, we sometimes find Boral’s shake-profile tile has shifted slightly, opening a gap where horizontal rain sneaks under. The fix is resetting the courses and checking the clip integrity. It’s a small repair that prevents a big one.

Our Boral Roof Inspection Process
When you call us for a Boral roof inspection in San Francisco, here’s how it goes:
- 1
We answer the phone. A live person takes your call, gets your address and roof age, and schedules a window that works for you. You’ll get a text before we arrive.
- 2
The walk. A background-checked, uniformed technician walks the entire roof. We map every slope, every penetration, every course of Boral tile. We photograph what we see.
- 3
Tile-level assessment. We count broken, cracked, or displaced tiles and note the pattern. We check nail-hole rust, clip condition, and whether the tiles are seated properly on their battens.
- 4
Underlayment and flashing check. We lift representative tiles at vulnerable points – valleys, hips, and the first course above the eave – to see what the underlayment actually looks like. We inspect flashing at every penetration.
- 5
The written report with dollar ranges. You get a document that says what’s wrong, what can wait, what should be done now, and what each repair costs. No vague language. Numbers on paper, before any work starts.
- 6
The fix and the guarantee. If you approve repairs, we schedule them. Everything we do is covered by the 365-Day Done Right Promise – in writing, for one full year, and we come back for free if it fails.

AfterWhat Boral Roof Inspection Costs in San Francisco
| Scenario | Typical Cost |
|---|---|
| Full Boral roof inspection with written report | $295 – $495 |
| Single tile replacement (tile + labor) | $85 – $180 |
| Flashings replacement at one chimney or skylight | $450 – $950 |

What moves the price: roof pitch, number of stories, how much tile needs to be lifted to reach the problem, and whether your tiles are still in production or need color-matched aftermarket stock. On steep San Francisco Victorian roofs near Alamo Square or Buena Vista, labor runs higher because of safety rigging. The first visit is a priced inspection – you’ll know the number before we leave. Call (831) 318-8819 to schedule yours.
Why San Francisco Homeowners Call Brennan Roofing Co San Francisco for Boral Work
Travis Oakley and our crew have been working San Francisco roofs long enough to know what the fog does to tile, what the salt air does to flashing, and what age does to underlayment. We operate under The Garrison Standard: written price before any work starts, background-checked uniformed technicians, and phones answered by a live person around the clock. If you need a Boral-tile repair and we recommend replacing with a different material instead – say, a GAF, Owens Corning, or CertainTeed system – we’ll tell you why plainly and price every option. Our 365-Day Done Right Promise covers every repair in writing for a full year. As Travis puts it, “A good roof shouldn’t need to be talked about – it should just hold.”
FAQs
We work in ways that don’t void your manufacturer warranty – we use correct fasteners, avoid unapproved sealants on tile surfaces, and follow Boral’s installation guidance. But we are an independent Boral service provider, not an authorized Boral agent. If your claim needs manufacturer review, our inspection report gives you the documentation to start that conversation. Call (831) 318-8819 for details.
Yes. We source quality aftermarket tiles with matching profiles and close color matches, and we can often track down new-old-stock Boral for specific series. Each repair starts by measuring the tile’s profile and color against current inventory.
Most inspections run 60 to 90 minutes, depending on roof size and access. You’ll have the written report in hand the same day.
No, but it helps if you can be available for the first 10 minutes so we can walk through any history you have – past leaks, recent repairs, or color-match attempts that didn’t hold. The rest of the inspection we handle on our own.
No. The number we put on paper before work starts is the number you pay. We operate under The Garrison Code – no change orders, no door-step markups, no surprises.
