Self-Build Roof Solutions

They can be used on a wide range of building types including timber frame, masonry and steel frame.

TRA members are always happy to help with your self-build roofing needs whether they are simple or complex. The package on offer always includes bespoke design to your exact project requirements and custom manufacture to meet your specified build schedule. Many members can also help with supply and fit or supply, fit and finish services to suit your needs and budget.

Furthermore, TRA members can offer a wealth of design experience as part of the roof package to help you achieve your self-build goals. The bespoke design service allows you the opportunity to customise the performance of your roof just how you want it. Here are some examples:

  • Extra living space through Room in the Roof solutions
