WindSmart is an advanced venting system engineered for commercial roofing applications. When paired with WindSmart’s proprietary air-sealing technology, it delivers exceptional wind uplift resistance while allowing the roof to breathe—effectively addressing the industry’s persistent challenge of eliminating trapped moisture. The system employs high-pressure flow vents to equalize low air pressure at roof corners and perimeters, redistributing it across the roof field. By drawing both air and moisture from beneath the membrane, WindSmart Systems secure the roof without the need for adhesives or mechanical fasteners.

WindSmart combines cost-effective, standardized proprietary air-sealing designs with one-way high-flow venting to perform in high wind uplift zones. This system forms a vacuum-sealed roof assembly that enhances energy efficiency, boosts wind uplift resistance, and removes the need for adhesives, fasteners, or ballast—delivering a higher-performing solution than traditional roofing systems.

WindSmart can be installed over any type of roof deck and is particularly cost-effective on non-fastenable substrates such as: • Structural concrete • Precast concrete • Lightweight insulating concrete • Tectum • Gypsum In these applications, the system eliminates the need for mechanical fasteners or adhesives, significantly lowering construction costs and shortening project timelines.

WindSmart is compatible with all types of single-ply membranes, including: • PVC • TPO • EPDM When installed with materials from Sika Sarnafil or Johns Manville, the system is covered under a direct warranty from the respective manufacturer.

• Significantly reduces installation labor and material costs by eliminating adhesives, fasteners, and ballast • Keeps insulation dry to maintain optimal thermal performance and occupant comfort • Improves overall energy efficiency by up to 15% compared to mechanically attached systems • Eliminates most VOC emissions and odors during installation • Allows installation in all weather conditions—no cold-weather limitations • Proven through testing to maintain insulation R-value over time • Features WindForce 365 vents that are modular, UV-resistant, impact-resistant, and warranted for the life of the roof

WindSmart requires on-site startup training for all new applicators and installation crews to ensure proper system understanding and performance. Once trained, certified applicators may choose between on-site or remote technical support for standard applications, ensuring quality installation and long-term success on every project.

WindSmart is approved for use nationwide, including coastal and special wind zones. On concrete decks, WindForce vents have demonstrated uplift resistance of up to 495 pounds, representing the highest performance recorded for any vented roof system on the market.

WindSmart’s moisture-removal capabilities have been verified through extensive laboratory and field testing. The system incorporates a standardized evaluation process to determine best practices for maintaining a dry roof assembly. When moisture is present in an existing roof, WindSmart can implement a mitigation strategy to gradually remove it. This process supports in-place insulation reuse, reduces landfill waste, and enables continuous recoverability—significantly lowering long-term ownership costs while advancing sustainable roofing practices.

WindSmart utilizes ASCE wind uplift calculations to determine optimal vent placement for each project. WindForce 365 vents are strategically positioned in the building’s highest uplift zones—typically at perimeters and corners. These one-way pressure flow devices can also be reconfigured for specialized applications as two-way vents, enhancing the system’s moisture removal capabilities.

WindForce 365 vents are completely maintenance-free and are warranted for the full life of the roof, including coverage against very severe hail and wind-blown debris. Routine membrane and waterproofing maintenance should be performed in accordance with the manufacturer’s recommendations.

A Sika WindSmart System is a roof assembly that incorporates Sika or Sarnafil materials and is warranted directly by Sika. Any Sika Sarnafil Approved Applicator can become qualified to install the Sika WindSmart System through approved training.

A JM WindSmart System is a roof assembly that utilizes Johns Manville materials and is warranted directly by JM. Installation is permitted by Peak Advantage Qualified Contractors, including members of the 5280 Council, Pinnacle Council, Summit Club, and Peak Level programs.

WindSmart can be installed in a “solar-ready” configuration without affecting its wind uplift performance. It is also one of the most cost-effective solutions for integrating solar arrays into a new roof assembly.

WindSmart is primarily designed for low-slope commercial roofs, but it can be installed on virtually any roof type, regardless of slope, size, or geometry. In addition to low-slope roofs, WindSmart has been successfully applied to: • Standing seam metal panel roofs • Gable roofs • Barrel roofs • Spherical roofs The system is most cost-effective on large, open roofs (over 100,000 sq ft) with non-fastenable decks, where traditional roofing approaches are typically unable to compete with the efficiency and performance of a WindSmart installation.

WindSmart employs a standardized 4-step project review process to efficiently and accurately evaluate system suitability for any building in the U.S. This process is conducted in collaboration with contractors, designers, building owners, and manufacturer representatives (Sika or JM).

WindSmart Systems have been tested by Underwriters Laboratories (UL) and comply with applicable codes, including IBC, IECC, and ASCE wind uplift standards. While WindSmart is not a licensed design professional, we provide expert technical support to assist contractors and design teams in applying the system in accordance with local codes and performance requirements.
