Roofing | What is a Slate Roof?
Roofing | Natural Stone is the ultimate eco-friendly, durable, and beautiful roofing material. Unfortunately, high cost and weight concerns make slate a rare sight on run-of-the-mill homes. You’ll most often see slate roofs on churches, libraries, and government and university buildings.
Roofing slates are manufactured from natural stone. Slate is metamorphic rock that formed under intense heat and pressure underground. As stone, it is very hard and will not saturate with water, and is completely fireproof. Yet it has a unique characteristic that allows it to be split into thin pieces that become roofing slates. Since slate is stone, it is impervious to weather, sun, heat, and cold so you can expect a slate roof to last a lifetime.
The color of slate is determined by its chemical and mineralogical composition. Since these factors differ in various locations, it is possible to obtain roofing slates in a variety of colors and shades. Upon exposure to the weather, all slate is changed slightly in color. The extent of this color change varies with different slate beds, being barely perceptible in certain slates. Those slates in which the color only slightly are classed as “permanent” or “unfading.” Those in which the color change is more marked and varied are known as “semi-weathering” and “weathering” slates. North American slate deposits currently producing roofing slate are found in Vermont, New York, Pennsylvania, Virginia, Quebec, Canada, and Newfoundland, Canada.
Cost of a Slate Roof
Slate that has been quarried for roofing is dense, sound rock, that is exceedingly durable. It is labor intensive–requiring specially trained workers to install which can be quite costly–$600-$1,500 per square installed. That said, slate is one of the highest quality materials you could select for your roof, so you will undoubtedly increase the value of your home. – Modernize
