Oldcastle Roofing: The Dallas Owner’s Guide
If you have Oldcastle roofing on your Dallas home, we can source the replacement part and install it right the first time. Typical Oldcastle roofing repairs in Dallas run $400 – $1,800, and a full Oldcastle-compatible reroof runs $8,000 – $20,000 depending on square footage, slope, and what’s underneath once we open it up. Most homeowners find us the same way: a leak shows up after a spring storm, or a roof inspection flags cracked tiles and failing underlayment before a sale.
We are an independent service provider. We’re not affiliated with Oldcastle, which matters if you’re parsing warranty language: Oldcastle’s product warranties cover material defects, but the labor warranty is whatever your installer put in writing. That’s why our written guarantee matters so much on repairs. If it fails within a year, we come back and make it right. You can hold that number to a date on a page, not a handshake.
Which Oldcastle Models This Applies To
Oldcastle’s roofing lineup here in Dallas shows up mostly in two forms: stone-coated steel panels and concrete tile. The stone-coated steel systems, including the ones branded under their older DECRA-ish profile lines, use concealed fasteners and interlocking profiles. The tile systems are heavier, molded concrete units that are dimensioned to mimic traditional clay tile. They do not interchange, and the fasteners, battens, and underlayment specs differ enough that mix-matching parts is how you get a warranty denial.
Here’s the compatibility gotcha we see on North Dallas and Plano homes every month: the profile code is stamped on the underside of the tile or the back flange of the steel panel, not on the face. If your roofer only looks at the exposed surface, they can order the wrong profile. We match the stamp, the length, and the nail-lug spacing before we quote anything. For steel panels, you’re generally safe with OEM or a quality aftermarket panel as long as the profile code and gauge match. For concrete tile, we lean OEM because the color batch variation in aftermarket tiles is exactly what homeowners notice from the street two years later.

Signs Your Oldcastle Roofing Is Failing
- Water staining on ceilings or upper walls: This almost always means underlayment has failed, not necessarily the tile or panel above it. Oldcastle steel and concrete are tough; the membrane underneath is what gives up first in Dallas heat.
- Cracked or shifted concrete tiles after a hailstorm: Dallas hail doesn’t just dent; it cracks tiles at the thinnest point along the interlocking channel. One cracked tile invites water to the next tile over.
- Rust streaks on stone-coated steel: The stone coating is sacrificial in spots, and once the galvanized substrate is exposed to North Texas humidity, you get streaking. It’s cosmetic at first, structural if it goes ignored for five years.
- Granules in the gutters: Stone-coated steel sheds granules for the first year or two. After that, significant granule loss means the coating adhesion is failing and the panel’s weather resistance is dropping.
- Daylight visible through the roof deck from inside the attic: This is never normal on an Oldcastle roof. If you can see light, you’ve got a fastener failure or a panel that’s been blown out of its interlock.
Replacement Cost & What’s Included
| Job Type | Dallas Installed Price Range |
|---|---|
| Single tile replacement (concrete) | $400 – $800 |
| Multiple tile replacement, includes underlayment patch | $600 – $1,800 |
| Stone-coated steel panel repair | $500 – $1,600 |
| Full Oldcastle-compatible reroof | $8,000 – $20,000 |
The range is driven by three things: how much underlayment has to come up, how steep the roof is (a 8/12 pitch on an Oak Cliff bungalow is different labor than a 4/12 on a Frisco build), and whether we’re matching existing Oldcastle tile or replacing full sections. Every quote includes parts, labor, disposal, and cleanup. You get a written line-item price before we start, and the number on day one is the number on the invoice. The work includes our one-year guarantee in writing. If it fails inside a year, we come back and fix it free. That’s the 365-Day Done Right Promise, and it applies to every Oldcastle repair we do in Dallas.

Here’s the honest split. You can safely check your own roof from the ground with binoculars: look for shifted tiles, raised panel edges, and granule piles in the valley. You should not get on a Dallas roof in July or after a storm, not on concrete tile, not on stone-coated steel. Tile is brittle and steel gets slick with dust and dew. A slip on a 6/12 pitch is a hospital visit, not a learning experience. And if you step on a cracked tile while investigating a leak, you’ll turn a $600 repair into a $1,800 one.
What we do is simple. We get on the roof, we inspect, we match the profile, and we give you a number before we pick up a tool. That’s the only way Trevor Nash knows how to start. Call (940) 204-5368 and you’ll get a real person, not a voicemail.
FAQs
Oldcastle stone-coated steel generally lasts 40 – 50 years in North Texas, while concrete tile can go 50 – 60 years with proper underlayment replacement every 20 – 25 years. The underlayment is what fails first in Dallas, not the Oldcastle surface material. Heat cycles and UV exposure break down the membrane, so plan on redoing the underlayment long before the tile or steel gives out. Call (940) 204-5368 for an inspection and written quote.
In most cases, yes. A cracked tile, a shifted panel, or a localized underlayment failure can be repaired without a full reroof in Dallas. We replace the failed part, patch and reseal the affected underlayment, and match the profile codes so the repair disappears into the surrounding roof. If the damage covers more than 30% of the roof or the underlayment has failed across an entire slope, replacement is the better number to compare because patching becomes throwaway money. For a written assessment, call (940) 204-5368.
Most single-tile or single-panel repairs take 2 – 4 hours on site, including teardown inspection and cleanup. We schedule the repair in a defined arrival window and give you a schedule in writing alongside the price. A partial underlayment replacement can stretch to a full day. We’ll tell you before we start, not after we find the problem.
We keep common Oldcastle tile profiles and stone-coated steel panels on hand for Dallas-area jobs, and we source the rest through our trade distributors the same week. That means most repairs happen without a long lead time. If we need to match a rare profile, we’ll tell you the lead time before we quote, not after you’ve already paid. We also stock parts for KraftMaid, Cambria, and Silestone on the remodel side, but roofing is what we’re quoting here.
No. The written price we quote is the price you pay, unless we both agree in writing to a change order for something we genuinely couldn’t see until we opened up the roof. That’s rare, but if it happens, you’ll approve the number before we proceed. The number on day one is the number on the invoice, and that’s what the Kingswell standard has meant since 2004.
