Maximizing Roof Performance with SlopeShield® Plus SA

By Emma Peterson.

A high-performance membrane designed for exceptional moisture protection and job site efficiency.

Anyone who has worked on a job site knows that moisture can derail even the best-laid plans. Informed by National Roofing Contractors Association and IIBEC guidelines, moisture infiltration driven by air movement can compromise the roof system, increasing the risk of premature failure. That’s why VaproShield®’s SlopeShield® Plus Self-Adhered (SA) is a game-changer. By blocking air movement, it reduces moisture infiltration by 90% more than vapor diffusion alone. This multi-purpose air barrier and permeable vapor retarder is an excellent choice for both new construction and reroofing projects.

Installed above the structural deck and below insulation layers, SlopeShield Plus SA protects a wide range of surfaces, from concrete to mass timber, helping to mitigate moisture-related damage. Additionally, as an air barrier in the roofing assembly, it enhances the building’s energy efficiency and overall environmental health.

The benefits don’t stop at post-installation performance—SlopeShield Plus SA also delivers significant advantages for contractors and installers on the job site, including:

• Jobsite Efficiency: With SlopeShield Plus SA, your building is protected from the elements for up to 180 days, letting your team shift focus to other projects or internal work without worrying about weather damage or construction delays.
• Versatility: Engineered for all climates—including extreme conditions—SlopeShield Plus SA withstands high temperatures up to 300°F, and install down to 20°F and rising ensuring reliable performance in even the toughest environments.
• Durability & Surface Protection: This membrane enhances job site accessibility with exceptional traction and durability, making surfaces safer for both foot and machine traffic.
• Ease of Installation: As a self-adhered membrane, SlopeShield Plus SA is easy for your team to install. It utilizes a patented, pressure sensitive adhesive that eliminates the need for a primer in most applications.
