Tile Roof Underlayment Replacement for Enhanced Protection in Sedona, AZ

A residential property in Sedona, AZ required a full tile roof underlayment replacement after the existing system showed signs of age and deterioration. The homeowner proactively pursued roofing services to reinforce the structure and prevent future water intrusion, opting to complete the project without insurance or lender involvement. This project focused on preserving the existing tile while upgrading the critical waterproofing layer beneath.

Project At-a-Glance

• Roof Size: 52 squares (approx. 5,200 sq. ft.)
• Roofing Material: Existing concrete tile (manufacturer varies – Boral/Eagle)
• Underlayment: FT Synthetics Platinum or CMI SecureGrip Max synthetic underlayment
• Project Type: Full tile underlayment replacement
• Insurance: None
• Location: Sedona, AZ

Challenge: Aging Underlayment Beneath Reusable Tile System

The primary issue was deterioration of the original underlayment beneath an otherwise serviceable concrete tile roof. While the tiles themselves were in good condition and suitable for reuse, the underlayment had reached the end of its functional lifespan, increasing the risk of leaks and water damage.

Additionally, maintaining the integrity of the tile during removal and reinstallation required careful handling. The project also needed precise waterproofing around all roof penetrations, valleys, and flashing points to ensure long-term performance in Sedona’s climate.

Solution: Comprehensive Underlayment Upgrade with Tile Preservation

To address these challenges, a full underlayment replacement system was installed while preserving the existing tile roofing materials. This approach delivered a cost-effective and high-performance solution.

• Careful removal of existing concrete tiles for reuse
• Removal and disposal of all deteriorated underlayment
• Installation of one layer of premium synthetic underlayment for enhanced durability
• Installation of new 1″x2″ cedar wood battens to support tile placement
• Replacement and reinforcement of flashing and waterproofing at all roof penetrations
• Installation of triple rib valley metal where applicable for improved water channeling
• Reinstallation of existing tiles with replacement of damaged pieces as needed
• Installation of closures at hips and ridges for added weather protection
• Full site cleanup and debris removal upon completion

Result: Long-Lasting Protection and Renewed Roof Performance

The completed project delivered a fully refreshed roofing system with modern underlayment protection beneath the original tile. The new synthetic underlayment provides superior resistance to moisture, heat, and UV exposure—key factors in Sedona’s environment.

Functionally, the home now benefits from improved drainage, reduced leak risk, and extended roof lifespan. From the homeowner’s perspective, the upgrade brings peace of mind knowing the structure is protected for years to come, without the expense of a full tile replacement.

Trust & Proof: Backed Materials and Workmanship Assurance

The project utilized high-quality materials from trusted manufacturers such as Boral and Eagle, both of which offer lifetime warranties on concrete tile products. In addition, the synthetic underlayment system was selected for its proven performance in demanding climates.

A 5-year workmanship warranty was provided, ensuring confidence in installation quality. The careful preservation and reinstallation of existing tiles, combined with upgraded waterproofing components, demonstrate a balanced approach between craftsmanship and long-term value.
