Slate is one of the most durable roofing materials available with longevity surpassing 100 years. They are known to be heavy and will require reinforced roof structure. They will of course cost a lot more than asphalt, however, a deep investment in a property that you plan to keep throughout your life. One of the most attractive features of slate is its natural beauty, followed by its durability and longevity. Slate’s color options include greens, grays, reds, black, and purple like colors, as well as tiles that have variegated colors. Moreover, slate shingles are shaped by hand to meet specific requirements and can be custom made in a variety of thicknesses and sizes. Like clay or cement tiles, slate is rather fragile. With the extra added complication of broken tile, replacing it is a complicated task. Slate runs by lots and each lot is different, which makes it nearly impossible to find replacement tiles that are a perfect match because it's made naturally by nature.
