Our modern design software allows the roof trusses to be designed for virtually any roof shape.
Traditional cut roof.
Building with them is known as stick framing.
A truss roof using factory made trusses which are delivered to site complete and just erected.
A roof truss consists of one or more triangular units constructed of straight pieces that are connected at the ends by joints.
This reflects the weatherproofing requirements of older roofing materials like thatch and peg tiles.
This means that each rafter is built on the job site using dimensional lumber.
The triangular shape of the truss adds stability and support by distributing weight away from the exterior walls.
Prefabricated trussed rafters also have distinct advantages over traditional cut roofs by being able to clear greater spans without the need for additional supports.
Traditional or cut roof.
The traditional option is steeply pitched rarely less than 35.
The timbers are often 400mm or so centres and vary in size according to span.
Every piece is measured cut and fastened together to form the rafter.
Dormer windows require their own mini roofs and great care must be given to their detailing and construction.
The finished structure is readily adaptable.
The roof can be cut in the traditional way or fabricated from mono trusses.
The overall construction of a traditional cut roof is to ensure that the load of the roof is evenly transmitted to the walls below.
They span from the wallplate to the ridge board providing a platform for the underlay battens and tiles.
50mm wide by 75mm 100mm or 125mm deep are all common.
Rafters are the traditional means of framing a roof.
A cut roof this is the traditional method of cutting the timber on site and building up the roof using rafters ridge boards joists and purlins etc the exact details being determined by the size of roof size of timbers etc.
Not only is the volume large enough to convert into living space but the structure can generally be easily altered.
