Roofs and Roof Drainage

Part of the Macmillan Building and Surveying Series book series (BASS)


The roof is the most vulnerable part of a building and hence its performance requirements have to be stringent. Although most roofs are structurally stable, problems do occur because of poor design and construction. All roof coverings are expected to be durable under a wide range of conditions. But this durability is often short-lived because the roof is invariably exposed to the extremes of temperature, solar radiation, snow loadings and wind action as well as to chemical, biological and mechanical agents.
