Delano Roofing Slate is a popular, smooth-textured material. Because of its performance qualities, deep black color and high production, architects repeatedly specify this natural slate for institutional, commercial and residential roofing projects. It is appropriate for both traditional and contemporary architecture. It has been used for many large scale projects. Being an “unfading” slate, this durable material will hold its basic color after many years of exterior use. Delano Slate is available in several sizes and is mostly sold in standard thickness.
