The single roof is a type of sloping roof. In this type of roofs, common rafters are provided on each slope without any intermediate support. Single roof construction is simple than other roofs. Single roof has some limitations. Single roof is used for small spans. If greater spans are used, then larger roof sections are needed. In single roof, if rafter feet are not tied together by means of a roof joist or binder, then this roof will have a tendency ,under weight ,to push the supporting walls outwards at top causing structural failure of the wall. Hence in larger span of roof, single roof is not recommended. The various forms of single roof are as follows: Lean-to-Roof: The lean to roof is defined as single slope roof with its upper edge adjoining a wall or building. Couple Roof: The couple roof include two lengths of timber (rafters) leaning against each other, tied where they meet at the top.
