Oldcastle Roofing: The Fort Lauderdale Owner’s Guide
We stock and install Oldcastle-compatible roofing components in Fort Lauderdale, with most replacement parts available same-day and installed pricing running $400-$1,800 for repairs and $8,000-$20,000 for full replacement depending on square footage and substrate condition. Homeowners usually discover a problem after a hard rain: water stains on the ceiling, granules collecting in gutters, or a shingle tab that flaps in the Atlantic breeze. In Fort Lauderdale’s climate, the failure often starts at the underlayment - the synthetic barrier beneath the shingles - where salt air and UV exposure degrade the bond faster than inland markets.
Which Oldcastle Models This Applies To
Oldcastle roofing products in South Florida fall into two main families: the StormStrong impact-rated shingle line and the Colonial Slate architectural series, both manufactured with Florida’s wind-borne debris code in mind. The critical compatibility point is the nail zone width - StormStrong uses a 1.5-inch reinforced strip, while Colonial Slate runs 1.25 inches. Mixing fasteners or overlaying one series on another voids the wind warranty and creates a lift point we’ve seen fail at 45 mph, which is below Fort Lauderdale’s 120 mph design standard.
To identify your exact series, check the underside of a loose shingle or the edge of a ridge cap for the molded stamp. It reads “OC” followed by a four-digit date code and series abbreviation. If the stamp is worn off - common after eight to ten years of sun exposure - measure the nail zone with a tape measure and note whether the shingle has a textured laminate layer (Colonial Slate) or a uniform flat face with embedded ceramic granules (StormStrong).
We carry both OEM Oldcastle components and Atlas aftermarket equivalents that match the Miami-Dade wind certification. The OEM part costs 15-20% more; the Atlas equivalent carries the same 130 mph rating and installs to the same fastening pattern. We list both on the written quote so you see the exact spec, not a generic “architectural shingle” line item.
Signs Your Oldcastle Roofing Is Failing

- Curling or cupping at the shingle edges. This happens when the asphalt saturant dries out - accelerated in Fort Lauderdale by the combination of UV index 10+ days and salt aerosol from the ocean. Once the edge lifts, wind-driven rain enters beneath the overlap and reaches the underlayment.
- Granule loss visible in gutters or downspout discharge. The ceramic granules are the UV shield; when they wash off, the asphalt core degrades in months rather than years. In Victoria Park, we regularly see this on north-facing slopes where morning dew lingers and promotes adhesive breakdown.
- Cracked or missing tabs after a storm. Oldcastle shingles are rated for impact, but the self-seal strip can fail if the roof deck temperature exceeded 160°F before the storm hit - common on poorly ventilated attics in Fort Lauderdale’s summer. The shingle lifts, the tab tears, and the fastener head is exposed.
- Water stains that appear in straight lines on the ceiling. This pattern tracks the shingle course below. It means water is entering at a seam and traveling horizontally along the underlayment until it finds a fastener hole or deck joint.
- Sagging at the ridge or soft spots when walked. The OSB or plywood deck has absorbed moisture and begun to delaminate. This is past the shingle layer - the substrate itself is compromised, and partial decking replacement is now part of the scope.

AfterReplacement Cost & What’s Included
For Fort Lauderdale homes, Oldcastle roof repair runs $400-$1,800 depending on how many squares are affected and whether the underlayment is intact. A full replacement with Oldcastle-compatible materials ranges $8,000-$20,000 for typical single-family homes between 1,800 and 3,200 square feet of roof area.
What moves the number: deck condition (we find soft plywood on about 30% of Fort Lauderdale jobs over 15 years old), whether the existing layer count is one or two (code allows one overlay; two means complete tear-off), and access complexity - mature banyan roots or zero-lot-line fencing in neighborhoods like Coral Ridge add labor hours for material handling.
Every quote from Rowan Construction Group is a flat written price with line-item breakdown: shingle type and brand, underlayment grade, drip edge, ridge vent if indicated, deck repair if found, and disposal. Under Clause 1 of the Haven Standard, that price is fixed before work starts. No change proceeds without a signed change order. The 365-Day Done Right Promise covers the installation, and the manufacturer’s warranty - 30 years on StormStrong, lifetime on Colonial Slate - covers the materials.
DIY or Call Us?

There’s a safe middle ground here. A homeowner can check the gutter granule load, photograph the shingle stamp from a ladder, and verify attic ventilation - count the intake and exhaust square footage. What we don’t recommend: walking a 6:12 pitch or higher, prying up sealed shingles to check the nail pattern, or attempting tab replacement. The self-seal adhesive requires 70°F and direct sun to reactivate properly; in Fort Lauderdale’s winter, that can take three days, and an improperly sealed tab is a lift point waiting for the next easterly.
Roof work at height carries genuine risk. Falls from residential roofs account for a significant share of construction injuries, and the cost of a single ER visit exceeds most repair bills. We carry full workers’ compensation and general liability; our crews are tied off on pitches over 4:12. If you’re uncertain about the scope, call (754) 254-7676 and we’ll schedule a free estimate with a documented photo record of what we find.
FAQs
In Fort Lauderdale’s subtropical climate, expect 18-22 years from a properly installed Oldcastle architectural shingle, compared to 25-30 years in cooler, drier regions. The salt air and high UV index accelerate granule loss and asphalt oxidation; homes within two miles of the Intracoastal tend toward the shorter end of that range. Call (754) 254-7676 for an exact assessment - estimates are free.
Localized repair is viable if the damage covers less than 15% of the total roof area and the existing shingles are still in production for color match. Beyond that, the patch becomes visually obvious and the wind uplift resistance drops at the transition. We measure the affected area and show you both numbers on the written quote. Call (754) 254-7676 for an exact quote - estimates are free.
A typical Fort Lauderdale single-family roof replacement takes two to four working days: one day for tear-off and deck inspection, one to two days for installation, and a half day for cleanup and final walkthrough. Weather holds and decking replacement add time; we build both into the schedule and communicate daily. Call (754) 254-7676 to check current scheduling - estimates are free.
We stock the most common Oldcastle-compatible components - StormStrong and Colonial Slate in the four colors most prevalent in Fort Lauderdale subdivisions, plus matching ridge caps, starter strips, and synthetic underlayment. Specialty colors or discontinued series require a two- to three-day order. We verify availability before we quote so there’s no surprise. Call (754) 254-7676 to confirm stock for your specific model - estimates are free.
