Astm e2397 is the established standard procedure for determining the dead and live loads associated with green roof systems.

Green roof dead loads.

We can provide more information on individual products or systems on request. The use of reliable and established products that comply with green roofing guidelines is important. 3 3 dead loads dead loads consist of the permanent construction material loads comprising the roof floor wall and foundation systems including claddings finishes and fixed equipment. The values for dead loads in table 3 2 are for commonly used materials and constructions in light frame residential buildings.
