- Abstract
- The general aspects and status of metals utilized for roofing purposes are discussed. Consideration which apply in general to all roofing materials and to metals in particular are given. Basic principles of metal-roof constructions are listed, together with descriptions of the type of seams, decks, nails, and coverings used. Galvanized sheet steel, terne, and copper roofings are discussed in detail because they constitute the bulk of present-day roofs. The durability of galvanized sheet-steel roofings is shown by the data obtained from outdoor-exposure tests conducted by the American Society for Testing Materials. Information on the maintenance of terne and galvanized roofs is given.
