Roofing Slate  is prestigious natural product with a proud history. Not only the construction designers, also the homeowners thought that roofing slate increases in value with time; it appreciates like precious metals. Other building materials depreciate in value.

Slate will increase the value of a property; it is a scarce resource with limited reserves. A slate roof is a "collectible" investment. removed from 150 year old buildings has good re-sale value for repair work. In most cases slate is replaced on old buildings because the battens and nails failed. The value of homes with views and water frontages can all be improved by the use of slate. The higher the value of the land, the greater the impact a slate roof will make.

Meanwhile, according to the British & Australian standards, this tough, durable and very beautiful slate is guaranteed by Welsh Slate for 100 years providing the slate is fixed in, which is the only slate in the world to carry such a guarantee, and this guarantee has been written. Except for this security, an independent UK study of different roofing materials revealed that if the cost of a roof is amortised over its expected life, slate roofs were the cheapest of all.
