A roof is the first line of defence against rain, hail, snow and wind entry.
High up and often overlooked, roofs are either the crowning glory of a building, exposed and proud, or a utilitarian solution for keeping out the rain, which is hidden from view. Whatever the approach, many factors must be considered to ensure the roof will perform as expected.
Roofs have been constructed in a wide variety of forms, dictated by technical, regulatory, economic or aesthetic considerations. They can be flat, pitched, vaulted, conical, curved, domed, lantern, gabled, monopitch or shed, hipped mansard or in combinations.
The aim of this resource is to identify and discuss the myriad of factors that need to be considered as part of the design and material selection to achieve a successful roof.
