PVC Roof Refurbishment with Elastomeric Coating and Service Walk Paths in Cottonwood, AZ

A retail center in Cottonwood, AZ slated to become a Marshalls needed a cost-effective way to extend the life of its existing PVC roof while adding access for service technicians. The owner selected an elastomeric restoration to secure a 10-year total system warranty, address new HVAC penetrations, and create durable walk paths. No insurer was involved.

Project At-a-Glance

• Roof size: 24,000 sq ft (≈ 240 squares)
• Roof type: Existing PVC single-ply commercial roof
• Coating system: Polyglass PB 70 elastomeric, 24 mils DFT, no primer required
• HVAC scope: Patch roofing and insulation at eight new units/curbs
• Walk paths: 600 LF × 3 ft wide; two additional PB 70 coats with embedded granules
• Warranty: 10-year total system warranty
• City: Cottonwood, AZ
• Insurer: None

Challenge: Restore a PVC roof, integrate new HVAC curbs, and navigate Arizona monsoons.

The roof needed refurbishment rather than replacement to control cost and downtime as the site transitions to a Marshalls. Eight new HVAC units introduced additional penetrations that had to be watertight and compatible with the restored system. Work landed in late August–early September, when Arizona’s monsoon season can create narrow weather windows in Cottonwood.

Solution: Elastomeric restoration with targeted curb repairs and reinforced service routes.

The team executed a focused restoration using Polyglass PB 70 to rejuvenate the PVC membrane and lock in long-term performance. Roofing and insulation were patched at the eight new HVAC curbs to ensure continuity before coating. To protect high-traffic areas, we added defined walk paths with extra coating build and traction granules so technicians can service equipment without prematurely wearing the field membrane, all while scheduling around daily storm forecasts.

• Patched PVC membrane and insulation at eight new HVAC units/curbs for watertight continuity.
• Applied Polyglass PB 70 elastomeric coating over the PVC, achieving 24 mils DFT without primer.
• Installed service walk paths: 600 LF × 3 ft wide with two additional PB 70 coats and embedded granules for long-wear, high-traction access.
• Sequenced work in late August–early September around monsoon forecasts to protect quality and safety.

Result: A warranted, technician-friendly roof ready for retail operations in Cottonwood.

The restored PVC roof now carries a 10-year total system warranty, with a uniform protective coating that enhances weather resistance, UV stability, and drainage around rooftop equipment. Reinforced walk paths channel foot traffic away from the field, reducing future maintenance and risk. For the property team preparing the new Marshalls, the project delivered peace of mind, safer access for service crews, and a reliable roofing system that supports a smooth opening in Cottonwood, AZ.

For building owners seeking roofing services in Cottonwood and the surrounding area, our elastomeric coating installation approach offers a fast, low-disruption path to a durable, like-new roofing system without a full tear-off.

Trust & Proof: Brand-name system and documented warranty.

Using Polyglass PB 70 at 24 mils DFT provided a proven elastomeric solution compatible with the existing PVC assembly. The project was completed with a 10-year total system warranty, aligning the building’s roofing performance with the demands of a busy retail center.
