Endorsements and Accreditations

With accreditations by The Steel Construction Institute to NHBC chapter 6.10 in accordance with B S 5950 part 5, the U-Roof system has been independently assessed by structural engineers Mason Clarke Associates and has exceeded performance criteria under stringent live load test conditions.
U-Roof have developed the necessary processes and systems over a five year period and are able to offer a 50 year structural warranty for warm roof projects.


“The U-shape profile combined with unique manufacturing processes and latest CAD delivers a more efficient and economical method of roof structure procurement and supply. U-Roof have created a truly “modern method of construction” accessible to construction firms of all sizes. The benefits are extensive; the speed of assembly, health and safety, energy saving performance and minimal training requirements.”

Working With:


The European operations of Tata Steel (formerly known as Corus) comprise Europe’s second largest steel producer. Tata Steel supplies a variety of innovative solutions to a broad range of markets. Their mild steel strip products are continually used in the development of the U-Roof high performance light gauge steel frame system. We only use hot dip galvanised 390 Nm Z275 grade high tensile steel.


Xtratherm manufacture rigid thermal insulation; EPS, Polyiso & Phenolic, for new build and refurbishment construction projects that deliver eco-friendly sustainable solutions. Xtratherm’s experience and expertise is in providing cost-effective, certified solutions to the construction industry for over twenty years. The comprehensive range of technology foams is supported by a suite of services for architects, contractors and self-builders. Whilst we would always suggest the application of a warm roof to minimum heating cost the system has been used successfully in many cold roof and cold frame solutions – with insulation being fit at ceiling level for house roof applications and ship lap timber or cladding application for outbuilding applications.
