Aluminum Shingle Roof Replacement with Duradek Walk Deck & Snow Guards in Flagstaff, AZ

A full roof removal and replacement was completed at an existing home undergoing a remodel in Flagstaff, AZ. The scope combined a Class A aluminum shingle system for the steep-slope areas, a TPO membrane for the rear low-slope section, a new Duradek walk deck, and comprehensive snow retention—delivered as a self-pay project with no insurer.

Project At-a-Glance

• Roof size: ~45 squares (≈4,500 sq ft).
• Shingle roof: Zappone aluminum shingles, Dark Brown.
• Low-slope section: Carlisle 60-mil TPO.
• Walk deck: Duradek 60-mil PVC (upper deck).
• Snow retention: 310 total snow guards (150 plastic + 160 Alpine).
• City: Flagstaff, AZ.
• Insurer: Self-pay (no insurer).

Challenge: Coordinating a multi-system roof during an active remodel in Flagstaff

The home was being remodeled, which meant sequencing tear-off, steep-slope metal shingle installation, a rear low-slope membrane, and a walkable deck surface without disrupting other trades. Transitions, penetrations, and future foot-traffic zones needed durable, watertight detailing that would hold up long-term.

Solution: A Class A aluminum shingle system with integrated TPO and Duradek walk deck

We delivered a unified roofing assembly tailored to the remodel timeline and the property’s mixed roof geometry.

• Removed the existing two-layer roofing down to the decking for a clean substrate.
• Installed Polyglass Polystick XFR fire-resistant self-adhered underlayment to support the new metal shingle system.
• Installed Class A Zappone aluminum shingles (Dark Brown), with all penetrations properly waterproofed and new metal edges as needed; thorough site cleanup on completion.
• Re-roofed the rear low-slope section with Carlisle 60-mil TPO to ensure reliable drainage and seam integrity.
• Installed a fully adhered Duradek 60-mil PVC walk deck on the upper deck, including PVC boots at penetrations, coated drip edge metal, and L-trim terminations.
• Added 310 snow guards total—150 plastic units plus 160 Alpine snow guards—to manage rooftop snow/ice movement across key roof planes.

Result: A durable, low-maintenance roof system ready for the next phase of the remodel

The property now has a high-performance, Class A fire-rated aluminum shingle roof with a low-slope TPO section and a walkable Duradek surface—fully integrated and watertight. The snow-retention layout provides predictable control at eaves and traffic areas, and the owner is covered by our 5-year labor warranty, with standard manufacturer product warranties on materials. The finished system enhances curb appeal, simplifies maintenance, and gives the owner confidence moving forward with the Flagstaff remodel.
