Greenstone Slate

Nu-lok™ Roofing System


Nu-lok™ is a roof installation system that combines 21st century technology and design with the industry’s most respected and desirable roofing material: Natural Slate. Slate has long been revered as the finest roofing material available. No other roof offers the same long-term investment value. Slate, as natural stone, is the most durable roofing product available, and is completely fireproof (ASTM E108-00, Class A). Slate’s inherent practicality combined with its distinctive natural aesthetic appeal has made it a favorite among architects worldwide.
