Roof Construction Methods


Traditional or Cut Roof


The traditional or cut roof is essentially a roof cut and assembled on site using individual timber members.It is normally constructed using rafters and purlins. Hips and Valleys are constructed. The most common structure used is where there is a gable at both ends of the roof. The wall plates are bedded on mortar and should be lapped where they meet.


Bolted Truss Roof


Many different shaped roofs can be constructed using the bolt system. Bolted trusses were used in many domestic building prior to the trussed rafter era.
