Abstract
An improved roof and method wherein each course of slate is underlain with an interlayment material layer such that the interlayment material acts as a base to the through joints, resulting in a reduction in the amount of slate used by approximately 40% to 50%. The slate meets side to side (the through joint), the underlaying interlayment material providing sufficient waterproofing to protect the roof as well as being of lighter weight and a more economical slate roof than the slate which it replaces.
