Each subsequent truss can then be hoisted into place installed and braced. At a minimum the slope of the roof deck the length of the slope the width of the sloped areas and.

A roof assembly includestheroofdeck vaporretarder substrateorthermalbar rier insulation vapor retarder and roof covering. Once the ground assembled roof component system is installed install ground bracing to the first truss in the system as outlined in b1. The roof garden waterproofing assemblies will incorporate membranes from 90 mil epdm and 80 mil tpo in deep garden applications to 60 mil material for the shallow garden assembly for standard 10 or 15 year warranties. A system designed to provide weather protection and resistance to design loads.

Suitable for convex concave and other complex slopes.
