Oldcastle Roofing: The Anaheim Owner’s Guide
Oldcastle-compatible roofing repairs in Anaheim typically run $400-$1,800 installed, with most common part replacements completed in a single visit. We stock Oldcastle-profile shingles, underlayment, and flashing components on our Anaheim trucks, and we can usually inspect, quote, and schedule within 24 hours. Most homeowners discover an Oldcastle roofing issue after a Santa Ana wind event or the first heavy rain of winter, when a lifted shingle or cracked tile suddenly becomes a leak in the ceiling.
Which Oldcastle Models This Applies To
Oldcastle BuildingEnvelope and Oldcastle Infrastructure products appear across Anaheim roofing in two main forms: the Oldcastle BuildingEnvelope line, which includes coated glass and metal panel systems used in commercial and multi-family re-roofs near the Platinum Triangle and Anaheim Resort districts, and the Oldcastle APG (Architectural Products Group) concrete and clay roof tiles common in 1990s-2010s tract builds in neighborhoods like Anaheim Hills and West Anaheim. The critical compatibility gotcha is the batten profile: Oldcastle APG Mission-style tiles require a 2-inch raised batten, while their Slate-profile line sits flat on the deck. Mix the two and you break the water channel. To identify your part, check the underside of a lifted tile for the molded date code and the “OC-APG” stamp. OEM Oldcastle tiles are still produced, but quality aftermarket equivalents from Eagle Roofing and Boral (now Westlake Royal Roofing) match the dimensions exactly and carry comparable Class A fire ratings. We source both and quote them line-by-line so you see the delta.
Signs Your Oldcastle Roofing Is Failing

- Cracked or spalling concrete tiles, especially on south-facing slopes. Anaheim’s 280-plus days of annual sun and thermal cycling above 95°F in July and August cause Oldcastle concrete tiles to shed their color hardcoat and absorb moisture; once freeze-thaw hits a December morning, the face pops off. We see this most in Anaheim Hills above the 91, where elevation adds UV exposure.
- Lifted or missing tiles after Santa Ana winds. The Oldcastle APG interlock relies on a 1.25-inch headlap; if the fastening nail has backed out or the batten has rotted, a 50-mph gust strips the tile. The underlying felt then takes direct rain until it fails.
- Granule loss on coated metal panels showing bare substrate. Oldcastle BuildingEnvelope coated metal systems lose adhesion at the seam fold first; once the coating breaches, the Anaheim coastal salt air (we’re 15 miles from Huntington Beach as the crow flies) accelerates corrosion from the edge inward.
- Water staining at ceiling corners or along drywall seams. Oldcastle tile systems depend on the underlayment as the primary water barrier; the tile itself is the UV and impact shield. When underlayment reaches end of life, typically 20-25 years in Anaheim’s heat, leaks appear days after rain even where tiles look intact.
- Sagging or rotted fascia behind gutters. Oldcastle roof-to-wall transitions often used a simple L-flashing without a kickout diverter; concentrated runoff rots the fascia and creeps up the rake board. We replace the flashing with a proper kickout and counterflashing assembly.

AfterReplacement Cost & What’s Included
| Scope | Price Range in Anaheim |
|---|---|
| Individual Oldcastle tile replacement (up to 10 tiles) | $400-$800 |
| Tile replacement with underlayment patch (section repair) | $800-$1,400 |
| Oldcastle metal panel seam repair or coating | $600-$1,200 |
| Flashing replacement at wall/chimney | $500-$1,000 |
| Full underlayment replacement, tile-off | $1,200-$1,800 |
The range depends on three factors: roof pitch (steeper means more labor hours), deck condition if we find rot during the tear-off, and whether the original Oldcastle color is still in production. Under Clause 1 of the Haven Standard, the price we write is the price you pay; if we find unexpected deck rot, we document it with photos, write a change order, and nothing proceeds until you sign. Every repair carries our 365-Day Done Right Promise and a written warranty with the photo record included as standard.
DIY or Call Us?

Here’s where we draw the line honestly. A homeowner can safely walk the roof with binoculars to spot missing tiles, check the gutter outlets for granule buildup, and photograph anything suspicious for us to review. What you should not attempt: walking a tile roof without proper weight distribution (concrete tiles crack under concentrated load), removing tiles to inspect underlayment (the interlock pattern is specific and easy to break), or working within 10 feet of any overhead electrical service drop. Anaheim’s older neighborhoods, particularly the flat-roofed commercial conversions near downtown, often have 240V service drops at eave height. We carry the liability insurance and the harness systems; more importantly, we know which Oldcastle profiles are still manufactured and which require custom sourcing. Call (562) 245-4592 and we’ll schedule a no-charge inspection with a written quote before any work starts.
FAQs
Oldcastle concrete tiles last 40-50 years structurally, but the color hardcoat fades significantly after 15-20 years in Anaheim’s UV exposure; the underlayment beneath typically fails at 20-25 years and becomes the real lifespan limiter. Call (562) 245-4592 for an exact assessment of your roof’s condition - estimates are free.
Most Oldcastle tile issues are repairable if the underlayment is still sound and you have matching tiles available; we only recommend full replacement when underlayment is failing across multiple slopes or the tile color has been discontinued and a patch would look like a patch. Call (562) 245-4592 for a written scope and price before you decide.
Individual tile swaps or flashing repairs take 2-4 hours; section repairs with underlayment replacement typically require one full day and a return visit for final inspection. We sequence the crew so no one is standing around waiting for materials - that’s the scheduling discipline that keeps our jobs on time. Call (562) 245-4592 to check availability.
We carry Oldcastle-profile tiles, matching underlayment, and standard flashing configurations on our Anaheim trucks; specialty colors or discontinued lines we source within 48 hours through our network, which includes KraftMaid, Cambria, Silestone, and fifty-plus other vetted brands. Call (562) 245-4592 to confirm your specific color and profile.
