Oldcastle Roofing Nationwide

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.

Replacement 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.
