Slate shingles have been used for many years. They are not used as much these days due to their high maintenance and expensive cost for installation. There is no shingle on the market today which will last longer than a Slate tile. The Slate roof itself is made of stone which can last upwards of 200 years. There are castles in England that are over 500 years so which have the original tile roof installed.
There are many contractors today who are unfamiliar with the installation of Slate tiles. This appears to be a lost art. The roofing companies that do install Slate tiles are very expensive. Many of the companies today will not even dare attempt the installation of a stone roof. So, with all that being said you may want to consider and asphalt roof for your home.
