Superior Quality & Function in One Easy-to-Install System

Enjoy a beautiful patio that complements the architecture of your home and lasts longer. Extend the living space of your home or business by utilizing your flat roof or integrate this option to a home addition.

Over the past few decades, flat roofs have developed a reputation for faulty water proofing strategies. We developed a system that allows homeowners to use the roof as a patio while extending roof life beyond conventional roofs.
