When selecting a roof for this business in Alabama, the property owner sought an affordable, yet beautiful alternative to real slate. EcoStar Niagara Slate was selected in Midnight Gray to provide long-lasting durability, superior protection against extreme weather conditions and 50 years of warranty coverage. Niagara Slate is a natural-looking, 5/8" thick, synthetic slate roofing tile produced in 10", 12" and 14" widths. This added size allows each Niagara Slate 14" tile to cover one square foot of roof deck at the 10" exposure (100 tile/square) while maintaining a minimum 2" of headlap throughout. An additional 9" exposure option allows for the creation of unique looks using staggered or random width offset installations. Niagara Slate Technical Info: UL Listed Class C or A Fire Resistance (UL 790) UL Class 4 Hail Impact Resistance (UL 2218) Wind Resistance per ASTM D3161 Class F (110 mph) Miami Dade prolonged and accelerated weathering @ 4,500 hours 50-Year Limited Material Warranty 50-Year Transferable Labor and Material Warranty available
