Oldcastle Roofing: The San Antonio Owner’s Guide
Oldcastle roofing parts – tile, underlayment, flashing, and ridge components – are installed and repaired across San Antonio for $400 to $1,800 depending on the part, the roof’s pitch, and how much surrounding material has to come off to reach it. We stock the common Oldcastle-compatible profiles on our trucks and can usually have the replacement done the same day we diagnose it. Most owners find out a part has failed the hard way: a water stain on the ceiling after a Hill Country storm, a tile that slid out of place near Alamo Heights and left the underlayment exposed, or granules collecting in the gutter after a long Texas summer.
We’re an independent San Antonio contractor, not affiliated with Oldcastle itself. What we are is a crew that has pulled broken Oldcastle tile off roofs from Stone Oak to King William and matched the replacement so the repair disappears into the original field. Graham Stein has written the scope down before a single tool leaves the truck on every one of those jobs – the price you sign is the price you pay.
Which Oldcastle Models This Applies To
Oldcastle’s roofing line in San Antonio shows up most often as concrete barrel tile, flat shake, and slate-look profiles. The gotcha we see regularly is that two tiles can look identical from the ground but have different water channels milled into their undersides. Oldcastle changed the channel depth on some of their S-tile profiles about a decade ago, and a tile from the wrong run will sit slightly proud of its neighbor and send water sideways instead of down. We match by the code stamped on the underside of the tile whenever we can, and by direct measurement of the channel width when the stamp has worn off.
The same applies to ridge caps and hip pieces. Oldcastle’s ridge caps are made to fit their specific tile profiles, and an aftermarket cap that is a quarter-inch off will open a gap at every joint. For most homeowners, OEM Oldcastle is the right call on tile and ridge, while quality aftermarket underlayment and flashing made to Texas spec is often the better value. We can walk you through which is which on your roof, and we carry both on the truck so the decision doesn’t add a second trip.

Signs Your Oldcastle Roofing Is Failing
- Water staining on ceilings or upper walls. In San Antonio’s summer storm pattern, a quick, hard rain will find a crack in a tile or a tear in the underlayment and leave a faint brown outline inside the house. By the time you see it, the underlayment below the tile has usually been wet for a while.
- Tile pieces in the yard or against the downspout after wind. Concrete tile is heavy but wind gets underneath the edges. A broken corner on a barrel tile is almost always the freeze-thaw cycle working on a hairline crack that started when the tile was walked on during a previous repair.
- Granules in the gutter or at the base of the downspout. If your Oldcastle installation used composition shingles as the underlayment or in a mixed-profile section, granule loss means the shingle’s UV protection is gone and the material is in its last seasons.
- Rust staining around flashing or pipe collars. San Antonio’s humidity, combined with the mineral content in rainwater running off limestone-rich areas, accelerates rust on metal flashing. A pinhole in a pipe collar will leak every time it rains, not just in storms.
- Tile that shifts or sounds hollow when tapped. A tile that has come loose from its mortar or fastening will rattle in light wind. It is one thing to look up and notice it, and another to wait until it lets go of the roof entirely during the next front that pushes through Bexar County.

AfterReplacement Cost & What’s Included
In San Antonio, Oldcastle tile or flashing repair runs $400 to $1,800 installed. Roof repair on the broader scale, when the failure has spread into the underlayment or the decking, lands between $400 and $1,800 as well. A full roof replacement for a home where the Oldcastle system has reached the end of its service life is $8,000 to $20,000, though most calls we take are for isolated tile, flashing, and underlayment repairs in the lower range.
The range comes down to three things: how high and steep the section is, how many courses of tile have to come off to reach the broken piece without damaging the ones around it, and whether the underlayment underneath is still sound. Every quote from Elmstead Remodeling San Antonio is written before work starts and includes the parts, the labor, the disposal, and a photo of the clean-up before the crew leaves. The 365-Day Done Right Promise covers the repair: if it is not done right, we make it right.
DIY or Call Us?
What you can safely do from the ground: photograph the damage, note which side of the house it is on, and check your gutters for tile pieces or granule buildup. Do not walk an Oldcastle tile roof. Concrete tile cracks under foot traffic faster than most other roofing material, and a roof with a broken tile already has a compromised spot. The slope of an Alamo Heights or Terrell Hills roof makes a fall a real possibility even for someone who has been up there before.
Matching Oldcastle tile is the bigger hurdle. The wrong under-channel profile or a mismatched ridge cap will leak, and then you have a second repair on top of the first. If you want an honest read on whether it’s a simple swap or a symptom of something under the tile, call (432) 233-0976 and describe what you see. We’ll tell you straight what it likely needs and give you a written price before anything is scheduled.
FAQs
Oldcastle concrete tile typically lasts 40 to 50 years in San Antonio, though the underlayment beneath it usually needs replacement at 20 to 30 years. The tile itself is tough; the Texas sun degrades the underlayment and flashing long before the tile surface fails. Call (432) 233-0976 and we can tell you whether your roof is at the tile stage or the underlayment stage.
Small chips can sometimes be sealed, but any crack that runs through the tile, or a tile with a broken water channel, should be replaced rather than patched. A patch that fails in a San Antonio storm will send water under the surrounding tiles silently. The repair cost is modest compared to the underlayment damage a failed patch can cause.
A single tile or ridge cap replacement usually takes under two hours once the crew is on site, including lifting the surrounding course and re-bedding everything. A repair that involves new underlayment across a roof section can take the better part of a day. We’ll give you the expected time in the written quote before work begins, so there are no surprises on the schedule.
We carry the most common San Antonio Oldcastle profiles – barrel S-tile, flat shake, and ridge cap – on the truck in standard colors, and we can source the stamped profile or less common color within a day or two. When Graham Stein writes your scope, he notes the exact part number so there is no guesswork on installation day. Call (432) 233-0976 and we’ll match what is on your roof before we roll out.
