Boral Roof Installation in Thousand Oaks: What to Know First

Boral roof installation in Thousand Oaks typically runs $14,500 to $28,000 for a full replacement on a standard single-family home, with most projects completed in 4 to 7 working days. We’re an independent Boral service provider, not a Boral-authorized dealer, which means we give you straight answers about what your roof actually needs instead of steering you toward a product line. If you own a Boral concrete or clay tile roof and you’re seeing cracked tiles, leaking underlayment, or flashing failures, this page tells you exactly what’s happening up there and what it costs to make it right. Call (805) 309-3314 and Grant Whitlock or a member of his crew will talk you through it.

How Boral Products Fail – and How We Fix Them

Boral makes excellent roofing materials, but every product has its weak points. Here’s what we see on Thousand Oaks roofs week after week.

• Boral Concrete Tile (Boral CST / BoralPremier): surface spalling and edge chipping. Concrete tiles in Thousand Oaks sit through brutal summer heat cycling off the Santa Monica Mountains, then winter rain. Over 15 to 20 years, the tile surface starts to shed its finish and the edges chip. What starts as cosmetic becomes structural when water gets into the porous concrete body and freezes during cold snaps. We replace individual broken Boral tiles with color-matched new or salvaged pieces, and we check the tile lugs underneath, because a loose lug is the real reason tiles crack in the first place.
• Boral Clay Tile (Boral Terracotta / Boral Sevilla): fractured barrels at the hips and ridges. Clay tile is fired hard and handles heat well, but it’s brittle. On Lang Ranch homes where the rooflines have steep hips, we routinely replace clay barrel tiles that cracked at the mortar joints. The cause is usually thermal expansion and contraction pulling the mortar apart, then the tile flexes and snaps. Our fix is to reset the tile in a flexible, waterproof bedding compound rather than stiff mortar, which moves with the roof instead of fighting it.
• Boral underlayment failures beneath the tile. Here’s a detail Boral’s own site won’t tell you: on most Thousand Oaks tile roofs, the underlayment wears out long before the tiles do. A 30-year Boral tile roof often has a 15 to 20-year felt or synthetic underlayment underneath. When that underlayment degrades, water leaks through the tile gaps while the tiles themselves look fine. We inspect the underlayment using infrared scanning and physical inspection at the tile laps, and we replace it in sections or fully, depending on what we find.
• Boral roof tile accessory failures: bird stops and eave closures. Boral tile systems rely on metal or plastic bird stops that seal the eave ends. In Thousand Oaks, we see these crack and pull away after years of direct sun, and then birds and rodents move in and tear up the underlayment. We replace worn Boral eave closures with durable, UV-stable versions that match the original profile.
• Flashing failures at roof penetrations and valleys. Boral tile roofs leak most often at the metal flashing around chimneys, skylights, and vents. On Boral roofs especially, the flashing is tucked under the tile, and once it corrodes or the sealant dries out, water follows the roof deck down and shows up inside the house, often far from the source. We replace the flashing with new galvanized or copper sheet work and re-tile around it, so the repair is invisible.

Our Boral Roof Installation Process

1. 1
   Written estimate and roof inspection. We schedule a visit, walk the roof, and photograph everything we find. You receive a written price before any work starts, no exceptions. If we find something mid-project that changes the scope, you approve the change in writing before we proceed.
2. 2
   Tile and underlayment decision. We identify which Boral series you have, whether we can source matching replacement tiles, and whether the underlayment needs partial or full replacement. We use OEM Boral tiles where they’re available and appropriate, and we’ll be upfront when a quality aftermarket tile matches better or costs less.
3. 3
   Removal and deck inspection. We strip the existing tile and underlayment, then inspect the roof decking for rot or damage. Any bad decking gets replaced before we lay the new underlayment.
4. 4
   Underlayment and tile installation. We install the underlayment with proper laps and fasteners, then lay the Boral tiles in the correct bond pattern for that series. We use the manufacturer’s recommended fastening schedule for the tile profile and the wind zone, which matters a lot in the Conejo Valley’s Santa Ana winds.
5. 5
   Final inspection and cleanup. We walk the roof with you, show you the finished work, and run a water test on any repaired areas. Then we magnet-sweep for nails and leave your property clean.
6. 6
   365-Day Done Right Promise. Every Mercer Roofing job includes a written guarantee. If anything we installed isn’t right within a year, we make it right. No fine print, no arguing.
