Boral Roofing Company in San Jose: What to Know First
Tilehurst Roofing San Jose is an independent Boral service provider that repairs and replaces Boral roofing systems across San Jose. Most Boral repairs take half a day to a full day once we’re on site, and you’ll have a written price in your hands before any work starts. Whether it’s a cracked Boral concrete tile, failed underlayment, or a leak that’s been chasing you through two rainy seasons, call (669) 274-0078 and we’ll tell you straight what it needs.
This page is for San Jose homeowners who already own a Boral roof. If you’ve got cracked tiles, a leak, or you’re wondering whether your Boral roof has another decade in it, you’re in the right place. We’ll cover how Boral products fail in the South Bay specifically, what repairs actually cost, and what we do differently from a general roofing crew.
How Boral Products Fail – and How We Fix Them
Boral tile is some of the toughest roofing material you can put on a San Jose house. But “tough” doesn’t mean “never fails.” Here’s what we see most often on Boral roofs across San Jose, from Willow Glen to Almaden Valley:
- Boral Barcelona and Boral Villa tiles cracking at the corners. The Barcelona line has a distinctive barrel profile that looks great but concentrates stress at the tile’s shoulder. When a San Jose summer pushes roof temperatures past 140 degrees, tiles expand, and if the original installer set them too tight, the corners crack. We replace the cracked tile and check the surrounding course for tight spots, so the same failure doesn’t happen again next August.
- Underlayment failure under Boral concrete tile. The tile itself can last 50 years, but the underlayment beneath it typically lasts 25 to 30 in San Jose’s dry heat. When underlayment degrades, water gets past it and rots the decking. On Boral jobs in the Cambrian and Rose Garden areas, we regularly find the tile in fine shape while the underlayment underneath has turned to brittle paper. The fix is a tile lift-and-reset: we remove the Boral tile, replace the underlayment, and reset the same tile if it’s sound.
- Boral Saxony and Boral Estate flat tile slipping after high wind. Flat-profile Boral tile relies on correct nailing and headlap. If the original installer nailed too high or skimped on fasteners, the tiles start sliding during Santa Ana wind events and winter storms. We reset the slipped tile, add the missing fasteners, and check the rows above and below, because where one tile slips, its neighbors are usually loose too.
- Valley and flashing leaks at Boral tile transitions. Open valleys on tile roofs channel a lot of water, and in San Jose’s older homes, the valley metal often wasn’t replaced when the roof was re-tiled. The metal splits, water finds the gap, and you get a ceiling stain that appears two rooms away from the actual leak. We trace the water path, replace the valley metal, and reset the Boral tile with a proper cut.
- Efflorescence and surface spalling on older Boral tile. That white chalky haze on older Boral tiles isn’t just cosmetic. It’s mineral salts leaching out as the tile’s surface slowly breaks down. We see it most on Boral roofs near the bay and in older San Jose neighborhoods where morning fog sits on the roof. If the tile is structurally sound, we assess and monitor it. If it’s spalling – the surface flaking off in layers – the tile needs replacement before water gets a path through.

Our Boral Roofing Company Process
When you call about Boral work, here’s what happens, step by step. The Kingswell Way is what we call it around here: say the price before the work, show up in the window we gave, leave the place cleaner than we found it.
- 1
You call (669) 274-0078. A live person answers, any hour. You tell us what’s going on – leak, cracked tile, staining, or just a roof that’s old enough to worry you.
- 2
We inspect the roof. Greg Holloway or one of our senior techs walks the roof, maps the damage, and identifies which Boral line you have. Tell me what’s on your roof and I’ll tell you what it needs – straight answer, no guesswork.
- 3
You get a written price. Before anything gets touched, we hand you a line-item quote. That price doesn’t change unless we both agree in writing to add scope – for example, if pulling tile reveals decking rot that was impossible to see from above.
- 4
We repair or replace. We use OEM Boral tile where the line is still manufactured, and quality-matched aftermarket tile for discontinued lines. For fasteners, underlayment, and flashing, we use materials rated for tile roofs, not whatever’s cheapest at the supply yard.
- 5
We test and document. After the repair, we water-test the area if weather permits and photograph everything. You get a written guarantee before the crew leaves, not mailed three weeks later.
- 6
We clean up. Old tile, nails, underlayment scraps – it goes in our truck, not your flower beds. We sweep the walkways and magnet-sweep the driveway for nails.

AfterWhat Boral Roofing Company Costs in San Jose
Here’s what Boral work typically runs in San Jose for single-family homes:
- Single tile replacement: $180 – $350 depending on tile profile and roof accessibility
- Underlayment spot repair with tile reset: $600 – $1,200
- Valley metal replacement under Boral tile: $900 – $1,800 per valley

Call (669) 274-0078 and we’ll give you a free written estimate with real numbers for your specific roof.
Why San Jose Homeowners Call Tilehurst Roofing San Jose for Boral Work
Plenty of roofing companies in San Jose will take a Boral job. Not many of them know the difference between a Barcelona and a Villa tile by looking at it from the ground. We do, because Greg Holloway has spent the better part of two decades running crews across San Jose, including a stretch of tile re-roofs near Willow Glen that taught him exactly how South Bay heat and winter rains work on older clay and concrete roofs.
Every Boral repair we do carries a written guarantee before we leave your property. If that repair fails inside the guarantee period under the 365-Day Done Right Promise, we come back and fix it at no charge. No phone tag, no “we’ll send someone out next week.” And if your Boral tile is beyond saving, we can walk you through options from seven manufacturers – GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and yes, Boral – so you’re choosing what fits your home, not what’s sitting in our yard.
FAQs
No. As an independent Boral service provider, we perform repairs that do not affect your original Boral warranty on unaffected tile. What can void a warranty is improper installation – using the wrong fasteners, wrong underlayment, or water-damaging a neighboring tile during a repair. We follow Boral’s installation specs on every job, so the work we touch is done to the same standard Boral expects.
Yes, in most cases. For current Boral lines like Barcelona, Villa, Saxony, and Estate, we source the exact tile from local San Jose suppliers. For discontinued lines, we work with regional tile recyclers and salvage yards to match color, profile, and weathering as closely as physically possible. You’ll see the match before we install it. Call (669) 274-0078 and we’ll tell you what we can source for your specific tile.
In most cases, we can get a crew to your San Jose home within 48 hours for a leak, and the repair itself usually takes half a day. If a storm is forecast, we’ll prioritize emergency tarping to stop water intrusion until a permanent Boral repair can be done. A live person answers our phone 24 hours a day, so you won’t leave a voicemail at 7 p.m. on a rainy Sunday and wait until Monday for a callback.
If the Boral tile itself is sound – no widespread cracking, spalling, or slippage – and the problem is underlayment or flashing, repair is almost always the right call. Boral concrete tile regularly lasts 50 years or more; it’s the components underneath that age out first. If the tile is failing across more than 15 to 20 percent of the roof surface, replacement starts making financial sense. We’ll give you an honest assessment, not a sales pitch.
Yes. Every estimate is free, written, and yours to keep. The price we quote is the price you pay, and if we find additional damage during the job, we stop and get your written sign-off before spending another dollar. Call (669) 274-0078 to schedule yours.
