PVC and Asphalt Shingle Roof Replacement Stops Chronic Leaks at Oak Creek Country Club Clubhouse in Sedona, AZ

The Oak Creek Country Club clubhouse in Sedona, AZ was experiencing multiple active leaks across its mixed-slope roof. The property owner opted to self-fund a full roofing upgrade—without an insurance claim—combining a new PVC system for low-slope areas with fresh asphalt shingles for pitched sections to permanently resolve ongoing water intrusion.

Project At-a-Glance

• Roof size: Approximately 135 squares (≈13,500 sq ft) across low-slope PVC and pitched shingle sections.
• Shingle system: CertainTeed Landmark asphalt shingles with CertainTeed DiamondDeck synthetic underlayment.
• Low-slope system: Carlisle 60-mil reinforced PVC in Sierra Tan.
• Insurer: None (self-funded).
• City: Sedona, Arizona

Challenge: Mixed Roof Design with Persistent Leaks and Sensitive Penetrations

The clubhouse roof consisted of both low-slope and pitched areas, multiple mechanical penetrations, and a history of recurring leaks that disrupted daily operations. The primary challenge was delivering a fully watertight solution across varying roof geometries—especially around HVAC units and vent penetrations—while minimizing downtime for ongoing club activities.

Solution: Integrated PVC Membrane and Landmark Shingles for Total Waterproofing

Our team installed a Carlisle 60-mil reinforced PVC membrane on all low-slope sections and replaced the pitched roof areas with CertainTeed Landmark shingles over DiamondDeck underlayment. All penetrations were re-detailed using PVC boots and new vents, and wall tie-ins were reinforced and sealed. This integrated roofing system created a continuous, manufacturer-backed waterproofing solution tailored to the clubhouse’s unique roof design and Sedona’s climate conditions.

Key Steps

• Carefully removed existing shingle sections down to clean decking where specified and hauled away all debris.
• Installed CertainTeed DiamondDeck underlayment and Landmark shingles on pitched areas for durable, code-compliant protection.
• Installed approximately 110 squares of 60-mil Carlisle PVC (Sierra Tan) across low-slope roof areas for long-term waterproofing.
• Lifted and reset rooftop AC and evaporative units to install membrane beneath, then re-secured equipment after completion.
• Waterproofed all penetrations with PVC boots and installed new T-top and square-top vents to improve ventilation.
• Reinforced wall tie-ins using a KM Coatings primer, fabric, and final coat system for added protection at transitions.
• Installed edge metal, including PVC-clad components where required, and sealed all terminations for a clean, durable finish.

Result: Leak-Free Performance and Long-Term Protection for the Clubhouse

Following completion of the roof replacement, all leaks were resolved and the clubhouse returned to reliable, uninterrupted daily operation. The new roofing system provides long-term protection and confidence for the property owner, ensuring the building is safeguarded against future water intrusion.

Trust & Proof: Warranties and Manufacturer-Backed Materials

The completed system includes a 20-year manufacturer product warranty from Carlisle, warranted for ponding water per the manufacturer’s definition, along with a 5-year workmanship warranty on installation. By combining Carlisle PVC and CertainTeed Landmark materials, this project delivers a proven, specification-driven roofing solution designed to protect both low-slope and pitched areas of the Oak Creek Country Club clubhouse in Sedona.
