Architectural Roofing Slate
Over time, this gray / green Vermont slate yields a variety of rich earth tones. When extracted from the quarry it is a monochromatic. Some slates, about 10-25%, will gradually change to soft tones of buffs and tans after exposure to the weather. Semi-weathering Gray Green slate gives a rustic, textured appearance to a roof and is used extensively on commercial, residential and institutional buildings.
All FireRock Slate meets or exceeds ASTM requirements as an S-1 rated roofing slate.
Slate is available in several grades or thicknesses ranges. Since slate is hand split, there is always some thickness variation, so each slate grade covers a range of thickness. It is generally considered that the better the grade, the better the aesthetic appearance as the characteristics of the stone become more apparent.
