Membrane roofing—including EPDM, TPO, and PVC—presents a unique challenge in winter weather. Because these materials are engineered to be low-friction, they are highly susceptible to "roof avalanches" where accumulated snow releases all at once. To mitigate this risk to pedestrians, vehicles, and landscaping, an engineered snow management system is an essential consideration for any sloped membrane roof.

For over twenty years, the PP115 pipe-style snow guard has been the industry’s most reliable solution for retaining snow on these slippery surfaces.

Why Membrane Roofs Require Specialized Retention

While membrane roofing is a durable coating, its lack of surface friction means snow cannot hold its own weight on a slope.

• Controlled Melting: The PP115 system is designed to hold the snow and ice in place, allowing it to melt and shed gradually as water rather than all at once as a dangerous mass.

• Protecting Vulnerable Areas: Installing these systems is critical above doorways, parking areas, and expensive landscaping to prevent liability and structural damage.

• Durability: Crafted from extruded aluminum with a stainless steel base plate, the PP115 is rugged enough to withstand intense winter pressure for decades.

Technical Performance and Customization

The PP115 is a versatile system engineered to fit the specific needs of both residential and high-profile commercial projects.

• Flexible Configurations: Available in two- and three-pipe configurations to match the snow load requirements of your region.

• AIA and Project Compatibility: The system is designed for installation directly into wood blocking or a metal deck. It is compatible with EPDM, TPO, PVC, and even lock-seam soldered copper roofs.

• Roof Material Flashing: To ensure an exact match, the PP115 is designed to be used with a target patch made of the roofing material.

• Aesthetic Options: The brackets and pipes can be powder-coated to match any roofing material color using RAL TIGER Drylac® exterior finishes.

Proven on the World’s Most Notable Projects

The reliability of the PP115 has been demonstrated on some of the most recognizable landmarks and infrastructure projects across North America.

• Professional Sports Landmarks: From the red-brick backdrop of The Warehouse at Camden Yards in Baltimore to Yankee Stadium in the Bronx and TD Garden in Boston.

• Critical Infrastructure: Trusted at LaGuardia International Airport, Philadelphia International Airport, and multiple air reserve bases.

• Residential Expertise: Featured on This Old House, where the system was installed on a residential EPDM roof to demonstrate its ease of installation and long-term safety benefits.
