This book was intended to introduce the student of architecture to the first principles upon which the roofs of buildings are constructed. The first part of the book is devoted to wooden roofs, and the method of ascertaining the strains that are exerted upon the timbers of a trussed roof. The second part of the book is devoted to iron roofs. Several examples of iron roofs of different designs are described and illustrated, and the principles of their construction are explained.
