Commercial Roof Restoration Saves 100,000 SF Rancho Cucamonga Shopping Center

Popular Shopping Center Gets Roof Upgrade That Benefits Shoppers & Tenants

A large community shopping center in Rancho Cucamonga—home to national retailers such as TJ Maxx, Bank of America, Panera Bread, and Lazy Dog Café—was facing serious roofing problems. The existing polyurethane foam roof had developed extensive blistering and multiple leaks. These issues threatened not only the property’s structure but also the comfort of shoppers and the daily operations of tenants.

The Contractor: P21 Roofing

With over two decades of experience, P21 Roofing is recognized throughout Southern California for delivering high-quality commercial roofing solutions. Serving Orange, Los Angeles, Riverside, Long Beach, Fontana, Downey Landing, and San Bernardino counties, P21 specializes in silicone and acrylic roof coatings that extend the lifespan of roofs by 10–20 years without the expense of a tear-off. They also install advanced polyurethane foam systems that deliver both durability and cost savings.

The Solution

P21 Roofing, in partnership with  Polyglass USA, developed a system to repair, protect, and extend the life of the shopping center’s 100,000-square-foot roof.

  • All blisters were cut out and repaired with Polyglass PolyPUF, a spray polyurethane foam insulation that improves energy efficiency and roof durability.
  • Roof penetrations were sealed with PolyBrite 73, a premium elastomeric mastic with StretchSpan Technology™ for superior flexibility and adhesion.

Step 2: Preparation

  • The existing roof was thoroughly power-washed using PolyClean, a specialized cleaner that removes dirt, grease, oil, and other contaminants to ensure proper adhesion of new coatings.

Step 3: Coating System

  • A base coat of PolyBrite 70, a premium 100% elastomeric acrylic roof coating, was applied in gray at 1.5 gallons per square.
  • A top coat of PolyBrite 70 in white was applied at the same thickness, creating a seamless, reflective membrane that delivers a 10-year warranty system.
  • Using gray for the base and white for the top coat provided clear visual differentiation, ensuring uniform coverage and quality assurance.

The Results

The roof restoration resolved all leaks and blisters, providing tenants and customers with a safer, more reliable shopping environment. The reflective coating also reduces roof surface temperatures, contributing to lower energy costs and extending the roof structure’s life cycle.
