Roof Trusses

DTE always tries to maximise the amount of practical offsite prefabrication of roof trusses in order to minimise installation time, working at height and the associated labour cost. While this is not always possible - as many buyers prefer to opt for the lowest cost of materials - we will always endeavour to design and supply the customer a complete solution

Timber Roof Trusses

DTE is the UK's leading supplier of timber roof trusses. Located in the UK with eight regional branches, we are able to provide national coverage along with local knowledge and service. We take you through the complete process including design, manufacture and delivery along with providing any after-sales support that you may require.

imageTimber Roof Trusses provide a flexible, practical, simple-to-erect engineered solution for roofing requirements. As they can use up to 40% less timber than a traditionally formed roof, they're not only more suitable, but can be more affordable.

Today, trusses are the most widely used form of roofing solution and the only option of framing to convert an architectural vision into a total roof structure.

Roof trusses are the ideal choice for all roofing projects including extensions, new builds, residential developments and commercial projects.

As the UK’s leading supplier, DTE has an outstanding reputation for roof trusses which are delivered on time at the right price. We are able to handle projects of any size and we always provide the very best customer service. Each project that we undertake is fully compliant with health and safety standards. Additionally we are registered to ISO9001, so you can be sure that all work we carry out is to the highest standards.

Attic Trusses

imageMaximising the amount of room in new and existing houses has become a growing priority in the UK housing market. Timber roof trusses are the most common method of constructing a pitched roof – and we’ve seen a significant rise in interest in attic roof trusses. Attic trusses are by far the most economical solution to adding rooms to a home, as they increase the habitable area by as much as 40% at little extra cost to the overall roof.

The flexibility of these components is undoubtedly what sets them apart from other methods of construction in this area. Our modern design software allows the trussed rafter to be designed for virtually any roof shape.

It is also possible to combine attic trusses with open web joists (Posi joists) to allow for easily accommodating - or modifying - electrical and plumbing services in the additional room.
