Unilock Roofing: The Orange County Owner’s Guide
If you’ve got a Unilock roofing product that’s failing, here’s the straight answer: we stock Unilock-compatible roofing components and install them across Orange County, with most parts swaps running $400 – $1,800 depending on the component and access. We carry OEM Unilock parts and quality aftermarket equivalents on our trucks, and a uniformed Bradford technician can usually diagnose the issue on the first visit. The typical call starts the same way: a homeowner notices a drip near the eaves, finds granules in the gutter, or spots a lifted corner after a Santa Ana wind event, and they want to know if it’s a repair or a replacement. Most of the time, it’s a specific part that failed, not the whole roof.
We’re an independent service provider, not affiliated with Unilock. What that means for you is simple: we work on the product, we don’t sell it for the manufacturer, so our interest is in fixing the part correctly, not pushing a full replacement you don’t need. Curtis Lane and our crews have been running Unilock roofing diagnostics across Orange County from Anaheim Hills to Balboa Island for well over a decade, and we’ve seen every failure mode this product has.
Which Unilock Models This Applies To
Unilock’s roofing line isn’t a single product. It spans concrete roof tiles, ridge caps, hip starters, and the underlayment accessories that go with them. The most common call we get in Orange County is for the concrete tile profile, which Unilock manufactures in a few distinct shapes. The compatibility gotcha most homeowners run into: Unilock’s interlocking tile design has a different side-lap geometry than the flat-profile tiles common on older Orange County track homes. You can’t mix a Unilock tile with a generic flat tile and expect the water channel to line up. When we identify a part, we check the underside of the tile for the molded product code and measure the side-lap depth, because those two details tell us whether you need an exact OEM match or whether a quality aftermarket equivalent will seat properly.
OEM versus aftermarket matters here. Unilock’s concrete tiles carry a manufacturer spec for compressive strength and freeze-thaw resistance. In Orange County’s coastal and inland climate zones, the freeze-thaw rating is less of a concern than UV degradation and salt air near the coast. OEM parts preserve the manufacturer warranty. Quality aftermarket tiles with matching profile and color can save 20 – 30% on the part cost without meaningfully affecting roof performance. We’ll give you our written recommendation either way, with the price difference stated upfront.
We also stock and install roofing-related parts for other brands we carry, including KraftMaid, Cambria, and Silestone, but Unilock roofing is its own section of the truck.

Signs Your Unilock Roofing Is Failing
- Granule accumulation in gutters or at downspout exits. Concrete roof tiles shed surface aggregate as they age, but heavy granule loss concentrated in one area usually means the tile surface is spalling, often from a manufacturing defect or long-term water saturation at that spot.
- Water staining on the underside of eaves or in the soffit. This typically points to a failed underlayment or a cracked hip starter allowing water to run under the tile course. The tile itself often looks fine from the ground.
- Lifted or shifted tiles after wind. Unilock tiles interlock, but the leading edge can lift if the mechanical fastener corroded or if the original install skipped the required clip at a valley or ridge transition. Santa Ana winds in Orange County test this every fall.
- Visible cracks radiating from a tile corner. This is a stress fracture, usually from foot traffic or impact. Hairline cracks let water into the substrate below, and in Orange County’s wet winters, that water sits against the underlayment and rots it from the top down.
- Daylight visible through the roof deck from the attic. If you can see light, water can get in. This is a structural underlayment and decking issue, not just a surface part, and it needs a professional assessment before the next rain.

AfterReplacement Cost & What’s Included
Installed prices for Unilock roofing parts in Orange County run on a real range. A single tile swap with color matching and sealant runs $400 – $800, but that’s the small job. A ridge cap replacement across a typical Anaheim Hills roofline runs $600 – $1,500. A full hip and ridge rebuild, where we remove and reset every cap and valley transition, runs $1,200 – $1,800 depending on linear footage and access. If the underlayment under a section has failed, you’re into roof repair territory at $1,500 – $2,500 for a section re-deck and re-paper.
What drives the range is access, not parts markup. A two-story home near Balboa Island with a 6:12 pitch costs more in labor and safety setup than a single-story ranch in Garden Grove. Every quote from Bradford Remodeling Co Orange County is a written price before any work starts. That price includes the part, the labor, the disposal of the failed material, and a written guarantee. No numbers move at the door. That’s The Garrison Standard in practice, and it’s why we put it in writing every time.
Every Unilock roofing repair we complete falls under the 365-Day Done Right Promise. If the repair fails inside that year, we come back and correct it at no charge. You get that in writing at job close, along with a clean site and a documented scope of what we touched and what we didn’t.
DIY or Call Us?
What you can safely check yourself: look at the roof from the ground with binoculars to spot obvious lifted or cracked tiles, check the gutters for granule buildup, and inspect the attic for daylight or water staining on the underside of the deck. That’s useful information for us and helps you understand what you’re looking at before we arrive.
What we don’t recommend walking on a concrete tile roof without the right pads, safety line, and experience reading the tile layout. Unilock tiles are load-rated, but stepping on the wrong point during a missing-tile repair can crack three more tiles and turn a $500 job into a $1,500 one. And any work on ridge caps, hip starters, or valley transitions involves working at height near the edge. If you’ve got a failing ridge or a lifted hip, call us at (562) 262-2907. Curtis and the crew would rather give you a straight price than watch you risk a fall. Straight number, clear scope, no surprises at final invoice.
FAQs
Concrete roof tiles typically carry a 30 – 50 year manufacturer lifespan, but the underlayment beneath them lasts 15 – 25 years in Orange County’s climate, so the limiting factor is usually the paper, not the tile. Call (562) 262-2907 if you’re at the 15-year mark, and we’ll tell you what to look for.
A hairline crack that hasn’t shifted can sometimes be sealed, but any crack that has opened past a hairline or allowed water behind the tile means the tile comes off and a matched replacement goes on. We carry color-matched stock for most Unilock profiles on the truck, so the repair usually happens same visit.
A single tile swap takes under an hour. A full ridge and hip rebuild runs half a day to a full day depending on access and roofline complexity. We’ll give you a written time estimate with the price, and we hold to it.
We keep common Unilock tile profiles, ridge caps, and hip starters on our service trucks, and we can source exact OEM matches from our supplier network in one to two business days for uncommon colors or profiles. Call (562) 262-2907 and we’ll check stock while you’re on the phone.
