Installed properly, a slate roof requires relatively little maintenance and will last 60 to 125 years or longer, depending on the type of slate used, roof configuration, and the geographical location of the property. Some slates have been known to last over 200 years.
Found on virtually every class of structure, slate roofs are perhaps most often associated with buildings, where longevity is an especially important consideration in material choices..
Slate is one of the most aesthetically pleasing and durable of all roofing materials. It is indicative at once of the awesome powers of nature which have formed it and the expertise and skill of the craftsman in handshaping and laying it on a roof.
