Apex roofs are built with 50 x 50 mm roof truss’ spaced 2 ft apart, with 18mm OSB board surface. Larger buildings would have larger framing on truss’, as a standard. Felted using Debotec torch on roofing felt (estimated life span of 10 – 15 years). We can offer a 3 layered roofing system which comes with a 20 year guarantee, direct from the supplier. We are happy to use other roof sheeting if required.
