Investigation has shown that the cost of the roof of any structure ought to bear a certain definite relation to the cost of the entire building, not only from the stand- point of protection, but also from appearance. Every permanent building should be roofed with a material which will give it lasting protection, and at the same time be in character with the house itself and its surroundings. Because it does possess these qualities, for centuries slate has been the criterion by which other roof coverings have been judged. A slate roof has that indefinable "something" which distinguishes any object of real value and completes the picture of a well constructed building or home.
