Roof Trusses in Leeds

Suitable for spans up to 4 metres. They are used primarily in small house extensions and garage construction.

Suitable for spans up to 5.5 metres. They are used in domestic type structures such as extensions.

Suitable for spans up to 9 metres. This is the most commonly used truss shape and will handily accommodate a water tank should it be necessary.

Generally used for spans over 9m. For this reason, they are primarily used in commercial projects or for large domestic dwellings.

The 6:4 truss can span similar spans as the Fan & Double W trusses but tend to be the most cost effective web configuration for trusses spanning over 10m as the timber sizes can remain smaller.

Primarily used in girder trusses which support on-coming trusses when there are no load bearing walls available.

Typically used for spans of 15 – 16 metres. Like Fan trusses, they are primarily used in commercial projects or for a large domestic dwelling.

Used to provide a sloping ceiling or skeiling effect. The ceiling member of the truss is raised above the wallplate which in turn gives extra internal head height.

The Scissor truss has a sloping bottom chord as a means of providing extra headroom. The difference between the top and bottom pitch is generally 12.5 degrees.

The Modified Scissor truss shares the same detail as a standard Scissor truss but introduces a flat section to the ceiling.

The Mono truss is diverse and can be used in several situations ranging from lean to roofs, hipped end roofs, spanning onto fire walls or used back to back onto a central corridor wall.

The Hip truss is most commonly used in hipped roof construction but can also be modified where a flat roof is required or for reduction in height due to a planning requirement.

The Lattice truss can be used for diverse scenarios such as infilling large attic sections around dormers and stairs or used at ridge level when the span is too large for a ridge beam.
