High-Performance Commercial PVC Roofing System Delivers Durability, Peace of Mind

Located in Albuquerque’s high-traffic North Interstate 25 corridor, the McLeod Business Park is a premier commercial hub that features multi-tenant flex industrial buildings. The park hosts a diverse mix of operations, ranging from destination retail and entertainment options like escape rooms to essential service providers like solar and medical mobility companies. 

When the aging buildings in the large industrial park required a complete roof replacement, the client sought a superior, long-term solution that would outperform the standard roofing offerings. 

The result: A high-performance roof engineered to withstand New Mexico’s extreme desert heat, delivering the lasting durability and peace of mind the client demanded. 

Priority Commercial Nationwide, a national commercial contracting firm headquartered in Dallas, specializes in large-scale commercial roofing, storm damage insurance claims, and preventive maintenance. Serving multi-state property managers and industrial portfolios across the country, PCN’s customers include healthcare centers and hospitals; K-12 schools and higher education campuses; and industrial, office, and retail buildings. 

Single-Ply PVC Roof Retrofit Process 

Rather than executing a costly, disruptive tear-off of the existing, aging metal roof, the team implemented a high-performance single-ply retrofit solution using a Mapeplan® PVC roofing system. This approach combined proven durability, weather resistance, and installation efficiency, leaving the building’s operations undisturbed, while structurally upgrading its asset protection. 

The corrugated channels of the existing metal R-panel roof were filled using custom-cut flute fill insulation. This filled the deep gaps between the metal ridges, transforming an uneven corrugated profile into a completely flat, structurally uniform surface. 

A continuous 1-inch Polytherm® Polyisocyanurate was laid over the leveled flute fill. This seamless overlay adds a high R-value thermal barrier across the entire roof plane, drastically lowering future building heating and cooling costs. 

The insulation boards were secured to the structural purlins beneath using specialized RhinoBond® induction welding plates and fasteners. Rather than penetrating the final outer roof membrane with screws, these plates sit directly beneath the membrane, ready for a non-penetrating bond. 

An ultra-durable, thick 80 mil Mapeplan PVC membrane was rolled out across the insulation layout. This single-ply sheet serves as the primary performance and waterproofing layer for the building. 

Using a RhinoBond induction welding tool, technicians activated the plates beneath the membrane from above. The magnetic tool emits localized heat that flawlessly fuses the underside of the PVC sheet directly to the grid of plates. This creates a highly wind-resistant, uniform hold without a single mechanical fastener piercing the exterior waterproofing surface. 

“Compared to other PVC options, Polyglass USA products have a smoother surface on the performance layer that I feel will keep the membrane cleaner longer,” shared PCN’s Cody Russell. “This will help keep energy savings down longer without costly cleaning every year like other PVCs need due to the scrim being more defined, creating grooves that dirt gets trapped in.”

A High-Performance Roof Restoration for a Key Logistics Hub

When a large industrial warehouse building in California’s Central Valley recognized its single-ply roofing system was worse for wear and continuing to decline, it was time to take action.

As the home base for a third-party logistics provider that specializes in comprehensive, food-grade supply chain solutions, from precision packaging and “club pack” assembly to nationwide transportation coordination for the consumer healthcare, food and beverage industries, a reliable roof was a requirement. This sizable roof restoration project called for trusted experts and proven products.

That’s when Barrier Specialty Roofing and Polyglass USA teamed up to restore the roof using Polyglass’ PolyBrite 90 Series silicone restoration system.

About Barrier Specialty Roofing Company

Barrier Roofing is a Fresno, California-based national leader in commercial roofing, solar and specialty coatings, with a four-generation history of excellence. Barrier specializes in high-performance solutions for commercial buildings, including polyurethane foam, cold storage insulation and energy-efficient “cool roof” systems. By combining cutting-edge technology with rigorous craftsmanship, the firm expertly manages millions of square feet of project space annually for clients across the Western U.S. and beyond.

Technical Solution

On the massive industrial building’s existing roof, Barrier observed seam and weld fatigue; membrane weathering and surface degradation; fasteners and plates that had backed out of the roof; flashing failures around rooftop equipment, skylights and system terminations; and membrane damage from screws, nails and fasteners.

To address these issues without a full tear-off, Barrier turned to Polyglass’ PolyBrite 90 Series silicone restoration system, a fluid-applied approach designed to extend the life of an existing roof rather than replace it.

Installation Process

Adhesion Testing and Surface Preparation

Barrier started the installation process by performing adhesion testing, producing pulls exceeding 6 lbs., which confirmed the roof’s suitability for direct-to-substrate installation of the fluid-applied restoration system. Next, all surfaces were thoroughly power washed to ensure proper adhesion for the layers that followed.

Seam and Penetration Reinforcement

The seams, skylights, HVAC curbs and penetrations were reinforced with 6″ PrimePoly Fabric embedded in PolyBrite 90.1 or PolyBrite 93 mastic, strengthening the roof’s most vulnerable points against future weathering and mechanical stress.

Final Silicone Coating Application

The entire roof was then coated in a single pass at 2.5 to 3 gallons per square, achieving a minimum dry film thickness of 35 mils across all areas, forming a seamless, weather-resistant membrane.

Project Benefits

According to the pros at Barrier Roofing, the PolyBrite 90 Series silicone restoration system provided several advantages that support a long-term, renewable roofing strategy rather than a cyclical tear-off and full roof replacement model, including:

  • Eliminating the need for a roof tear off
  • Ability to leave the existing roof membrane in place
  • Minimal impact on building operations, and quick installation
  • Being more cost effective than roof replacement
  • Reduced impact on the landfill

At completion, the customer had the reliable roof it required, and the Barrier Roofing and Polyglass USA partnership delivered a seamless, high-performance restoration.

Mountain Island Charter School: An Energy-Efficient Roof Coating Project in North Carolina

A High-Performing Roof for a High-Performing School

A best-in-class education requires best-in-class facilities, and that includes a roof that keeps students and educators safe, and ensures learning happens in a comfortable environment.

That’s why Mountain Island Charter School, a K-12 tuition-free public school that serves students in the counties surrounding Mount Holly, North Carolina, called in the experts – We Coat Inc. and Polyglass USA – when it was time for a new coated roof system.

The Roofing Contractor: We Coat Inc.

We Coat Inc. is a veteran- and family-owned business based in Charlotte, North Carolina, that provides an eco-friendly substitute for roof replacement. The pros at We Coat know that a durable, high-performing, energy-saving roof is a major investment – one that requires a trusted partner. From schools like Mountain Island to retail spaces, warehouses and industrial facilities, We Coat and its certified applicators deliver safe and reliable results from start to finish.

We Coat’s roof coatings are built to strengthen and extend the life of clients’ roofs. Whether that roof is metal, flat or low-slope, We Coat’s efforts create a strong, weather-resistant barrier that keeps UV rays, moisture and wear at bay – sometimes at half the cost of other roofing options.

The Challenge: Extending the Life of an Aging TPO Roof

Like many schools managing tight facilities budgets, Mountain Island Charter School needed a way to protect and extend the service life of its existing Thermoplastic Polyolefin (TPO) roof without the cost and disruption of a full tear-off and replacement. The solution needed to restore waterproofing performance, improve energy efficiency, and hold up under North Carolina’s seasonal weather, all while keeping the 32,500-square-foot campus roof watertight throughout the project.

The Polyglass Solution: A Multi-Layer Elastomeric Coating System

The roof project at Mountain Island Charter School began with applying PolyBrite 79, a VOC compliant solvent-based primer, followed by PolyBrite 73, a premium-grade white elastomeric mastic with StretchSpan Technology™ (SST) applied directly to the existing Thermoplastic Polyolefin (TPO) roof’s flashing, penetrations, and details.

PolyBrite 77, a thermoplastic rubber coating and mastic designed for waterproofing a variety of structural surfaces, was applied next to seal fasteners. Then, a fully reinforced PG 700, a high-quality, water-based elastomeric coating that cures to form a seamless membrane, was applied over the entire roof area. In addition to keeping the surface cool with an initial SRI or 110, PG 700 extends the life cycle of new and existing roof systems, providing protection from ultraviolet sun and other weather exposures.

The new coating system improves the school roof’s sustainability thanks to higher reflectivity, and reduces the heat load and HVAC demand. Plus, the use of Polyglass USA products ensures that the newly coated roof has superior UV resistance, weatherability and waterproofing – extending roof’s life and reducing maintenance compared to the previous roofing system.

And the new roof comes with a 20-year No Dollar Limit (NDL) warranty – huge win for everyone involved.

PVC Roofing Membrane Upgrade: A Sustainable Roof Solution in Dallas

Featuring 19 meticulously manicured gardens, tree-lined pathways, and vibrant seasonal floral displays, a world-renowned arboretum and botanical garden in Texas creates a breathtaking urban oasis. The location is also home to world-class festivals every spring and fall and a cutting-edge educational facility focused on life and earth sciences.

In other words, it’s a cultural gem, a draw for guests from around the world, and a dynamic hub for environmental education and community engagement.

So, when it came time to reroof four buildings at the site, protecting the arboretum’s legacy was front of mind for roofing contractor Zenith Roofing and Polyglass, USA.

Zenith Roofing is a North Texas commercial roofing and waterproofing company that specializes in long-term roofing solutions for commercial and industrial properties. Zenith can handle anything roofing-related thanks to 45 years of experience in commercial applications, maintenance and repair, and residential projects.

From shopping centers to high-rises to hospitals, Zenith Roofing provides solutions to even the most challenging projects, making reroofing four buildings at the arboretum entrance a hurdle the Zenith team was prepared for.

That said, the project was not without issues. Very low parapet walls and unusual slopes made it difficult to ensure proper drainage. Using standard taper plans would be too high, and extremely low flashing areas presented additional challenges. With this in mind, Zenith turned to Polyglass USA’s PVC membrane products as the optimal solution.

“The project was originally specified as a bright white Polyglass modified bitumen roofing system. After evaluating the field conditions, however, the short capstone parapet and adjacent windows were determined to be better suited for a PVC application. Based on these conditions, local Polyglass representative Dylan Homa recommended Polyglass Mapeplan PVC as the preferred solution due to its greater flexibility and ability to accommodate the tight tolerances required for the project,” explained Zenith Roofing’s Tom Denton.

Roofing Systems Built for Energy Efficiency and Durability

The project included the use of an entire suite of Polyglass PVC products, including Mapeplan® PVC Roofing Membrane, Mapeplan® P SB, Mapeplan® P Prefabricated Accessories, Polylock™ LRF ECO, Polyglass Polytherm®, Polyflash® Flexible Curb Kit, and PolyFlash® 1C.

Today, the new roofs are sustainable, durable, and cost-effective. The benefits include:

  • Chemical and fire resistance:The updated roofs naturally resist damage from harsh chemicals, greases, and fire.
  • Durability:The flexible material withstands harsh weather, high winds and structural shifts without tearing or puncturing.
  • Energy efficiency:The Polyglass roofing materials act as a “cool roof” that reflects UV rays and helps lower cooling costs.
  • Proven performance:A Polyglass PVC roof lasts 20-30 years.
