Boral Roofing: The Los Angeles Owner’s Guide
We stock and install Boral-compatible roofing components across Los Angeles, with most Boral part replacements running $470 – $2,125 installed depending on tile count, underlayment condition, and roof pitch. If you’ve got a cracked Boral tile, a failed flashing joint, or a leaking valley, we can usually match the profile and color within a day or two of the initial inspection. Most Los Angeles homeowners discover a Boral problem the same way: a water stain on the ceiling after the first heavy rain of the season, or a tile that slid out of place during a Santa Ana wind event and is now sitting in the gutter.
One thing worth knowing before you read further: we are an independent Los Angeles remodeling and roofing contractor, not a Boral factory dealer. That matters because we’re not tied to a single product line. If a Boral OEM part is the right call, that’s what we recommend. If an aftermarket equivalent is equal or better for less money, we’ll tell you that too and show you the price difference in writing before any work starts.
Which Boral Models This Applies To
Boral’s roofing lineup in the U.S. market breaks into two main families: concrete roof tile and clay roof tile. Within those, the profiles you’ll see most often across Los Angeles are the flat “Boral Flat” tile, the barrel “Mission” profile, and the “Slate” profile that mimics natural slate at roughly a third of the weight. Each profile has its own dimensions, and here’s the gotcha most homeowners don’t know: Boral has shifted manufacturing plants and product codes over the past decade, so an older tile from a now-closed facility may not match a brand-new tile from a current plant even if both are labeled “Mission.” The dye lots and barrel curvature are close, but not identical. That’s why we physically match the tile on the roof rather than ordering blind from a part number.
When we come out, we look at the back of a sample tile for the cast-in manufacturer code, measure the tile’s overall length and the barrel rise if it’s a Mission profile, and note the weathering. Sun-bleached Boral tiles in Los Angeles fade predictably after 10 to 15 years, so even a perfect OEM match will stand out against the existing field. In those cases, we often pull matching aged tiles from the less visible rear slope to patch the street-facing front, then place the new tile in the back where the color difference doesn’t show. It’s a small thing that makes the finished roof look right from the curb.
On the aftermarket question: for Boral cement tiles, several reputable manufacturers produce dimensionally compatible profiles, and for older discontinued lines, an aftermarket tile may be the only practical option. For clay, we generally stay OEM because clay bodies and glazes vary more dramatically. Our practice is to show you both prices in writing and let you decide with real numbers in front of you.

Signs Your Boral Roofing Is Failing
- Cracked or chipped tiles after a wind event. Santa Ana winds in Los Angeles routinely lift loose tiles and drop them. A single cracked tile isn’t an emergency, but water reaching the underlayment speeds up its breakdown. Left alone, a cracked tile becomes a soft spot in the sheathing within a season or two.
- Water stains on ceilings or exterior walls. This usually means the underlayment has already failed somewhere above the stain, not just that a tile is cracked. Tile is a rain screen; the real waterproofing on a Los Angeles Boral roof is the underlayment underneath. By the time water shows up inside, the leak has usually been working for months.
- Tile granules collecting in gutters. Boral cement tiles shed a fine sandy material as they age, especially on west-facing slopes hit by afternoon sun. Heavy granule accumulation signals that the tiles are nearing the end of their effective service life, even if they still look fine from the street.
- Visible flashing separation at chimneys, skylights, or walls. Metal flashing expands and contracts with Los Angeles heat cycles and eventually pulls away from the mortar or sealant around penetrations. Most roof leaks on Boral roofs in Los Angeles are flashing failures, not tile failures.
- Sagging or soft spots when viewed from a ladder. If a section of the roof line looks wavy or a tile sounds hollow when gently tapped, the underlying sheathing has likely absorbed moisture and begun to rot. This is the point where a simple tile swap turns into a repair that includes decking replacement.

AfterReplacement Cost & What’s Included
For the Los Angeles market, a Boral tile repair typically runs $470 – $2,125 installed. At the low end, that’s a handful of replacement tiles and an hour of labor on a single-story roof with easy walk-up access. At the high end, you’re looking at replacing a roof penetration, rebuilding flashing, swapping out damaged underlayment, or working on a steep second-story slope that requires scaffolding and safety tie-offs. Most mid-range Boral repairs in Los Angeles land between $710 and $1,500.
Every quote we write includes parts, labor, debris removal, and the underlayment patching needed to keep the repair watertight. There are no surprise line items added after the work starts. The number on your written quote is the number on your invoice. That’s the Kingswell standard we’ve held since 2004: say the price before the work, show up in the window we gave you, leave the place cleaner than we found it. Every Boral repair also carries our 365-Day Done Right Promise in writing. If the repair fails inside a year, we come back and fix it at no charge.
| Boral Roofing Component | Typical Installed Cost in Los Angeles |
|---|---|
| Single tile replacement (1 – 5 tiles) | $470 – $945 |
| Flashing repair at chimney or skylight | $710 – $1,650 |
| Valley leak repair with underlayment patch | $945 – $2,125 |
| Roof penetration re-seal (vents, pipes) | $590 – $1,180 |
DIY or Call Us?
Some things are safe to check from the ground: count how many tiles are cracked, take note of where the stain is on your ceiling, and check if any tiles are visibly out of place along the eaves. You can clear a gutter of granule buildup without getting on the roof. That’s information we can use when we arrive.
But walking a tile roof is not a homeowner-level task. Boral tiles are heavy, and walking them wrong cracks more tiles than you had when you started. A cracked tile on a second-story pitch with Los Angeles sun on it is a slip and fall waiting to happen. The cost of a repair is a lot less than the cost of an emergency room visit or a bigger roof section that now needs replacing because a wrong step broke six more tiles. If the problem is at a flashing point or a valley, that work also involves sealing and waterproofing details that fail invisibly when done wrong. Call us at (213) 277-6578 and we’ll give you a straight answer and a written price before any tools come off the truck.
FAQs
Boral cement tiles in the Los Angeles climate typically last 40 to 50 years, though the underlayment beneath them usually needs replacement at the 20 to 25-year mark. Clay tiles can last 75 years or more, which is one reason many older Los Angeles homes still have their original clay tile roofs. The tile is rarely the first thing to fail; the underlayment and flashing are. Call (213) 277-6578 if you’re not sure whether you need a repair or a full underlayment replacement, and we’ll give you an honest read.
In most cases, no. Cement and clay tiles are not repairable once cracked through the body, and surface patching compounds fail quickly under Los Angeles heat and UV exposure. Replacement is the only durable fix. The good news is that a single-tile replacement is usually under $950 installed. Call us for a written quote.
Most single-tile and flashing repairs are completed in two to four hours on site. Repairs involving underlayment removal or multiple roof penetrations may take a full day. We’ll give you a defined arrival window when we book the call, and a written timeline with your quote.
We keep a working inventory of the most common Boral profiles used across Los Angeles homes, including Mission barrel and flat profiles in the colors most prevalent in the area. For less common profiles or older discontinued lines, we’ll locate the tile through our local supply network, which usually takes a few days. Either way, you’ll know the timeline and the price before we start.
No. The written price we give you before the job begins is the price you pay, full stop. If we open up a section and find hidden damage to the sheathing or structure, we’ll stop and show you exactly what we found, then give you a new written number before we do anything else. No change orders without your sign-off, no surprises on the invoice. That’s how we’ve worked since 2004, and it’s the only way Trevor Nash will run a job.
If you’ve got a Boral roof problem in Los Angeles, call (213) 277-6578 for a free estimate. We’ll give you a number first, then pick up the tools.
