System highlights

Mechanically attached - Provides excellent wind uplift resistance and can be installed quickly and easily, making it a popular choice for commercial and industrial roofs.
Adhered - Enhances performance and insulation by providing excellent wind uplift resistance and code approvals. It helps maintain a higher R-Value and minimizes membrane flutter.
Induction welded - Boosts productivity with faster installation and fewer screws/plates. It enhances performance with better wind resistance and eliminates half sheets, reducing membrane flutter.
Torch applied - Offers cost-effective, lightweight roof designs with durable, long-lasting performance thanks to its specially formulated modified asphalt.
Cold Applied - Consider Cold Applied roofing for safety, foot traffic, and hard-to-reach roofs. It’s cost-competitive and reduces clutter from equipment.
Heat Welded - Heat Welded roofing is characterized by low maintenance requirements, the ability to be installed in cool weather, and easy repair after installation.
