Slate Roofing

Slate roofs simply have no equal in durability. Their natural beauty enhances the aesthetic design of any building with its rich color and texture. ​Slate is a natural stone that is virtually impermeable by water and extremely durable to the harshest freeze-thaw cycles. Variations in color and thickness ensure that no two slate roofs will ever be identical. Slate roofs can last in excess of 50-100 years. Our highly skilled craftsman offer the highest quality workmanship and attention to detail.
