Modern roofing options are the result of eons of invention and experimentation. Some, such as slate and wood shakes, have remained virtually unchanged for centuries. Others, such as asphalt/fiberglass composites, lightweight concrete, and coated-metal tile, are products of the technological revolution. Each has slightly different durability, appearance, cost, and ease of application.
When installed correctly, slate is often considered to be the most durable and permanent roofing material available. In addition, its natural beauty is timeless. Slate roof structures have many positive qualities. Durability, low maintenance and resistance to fire and staining have made this natural material desirable to many. If maintained properly, the majority of slate roofs can be repaired as they have the capability to last a lifetime. Slate is a natural stone and it does have the potential to break or crack. If this should happen, repairs will be needed to prevent a leak or other structural problem.
