What Is Slate Roofing?
Slate is a fine-grained, foliated, homogeneous metamorphic rock derived from sedimentary rock composed of clay or volcanic ash.

The Advantages of Using Slate Roofing
Slate Roofing is known as one of the highest quality, longest lasting roofing materials on the market.
Since slate tiles are natural stones, no two tiles are alike, which adds a nice touch of uniqueness and character to your property. And even with today’s technology, the classic look of natural stones simply cannot be fully duplicated, which is why this “primitive” material is still preferred by many high-end property owners to this day.
Aside from its beauty, many property owners prefer slate roofing also because of the longevity it offers. In fact, professionally installed slate roofing can last for over a century with minimal maintenance, which is why it is sometimes called the “hundred year old roof.” With other roofing materials that are expected to last 20 to 30 years, slate roofing is clearly the winner when it comes to longevity.
Because slate roofing is made of natural stone tiles, it is completely fire-resistant. It also has an extremely low water absorption index of less than 0.4%, making it waterproof.
Due to its longevity and the fact that it is a natural material, slate roofing is one of the most environmentally friendly roofing options available today. It does not need replacement every few years and does not consist of harmful substances.
Slate roofing is a diminishing art form that has been a part of our roofing heritage for hundreds of years. At DeFrehn Roofing, we proudly continue this historical tradition of slate roofing & repairs.
