ASM Eave and Rake Edges (Copper)
ASM Eave and Rake Edges (Copper)
The details listed provide metal panel installation information and the fabrication of metal flashing details for non-ferrous metal standing seam roof systems. More specific details are available from metal panel manufacturers.
Copper Standing Seam metal roofing systems must meet or exceed RoofStar Guarantee Standards for architectural concealed fastener metal roofing systems (refer to Section 2.1.4 and 8.1.6.1). RGC Guarantee Standards for the application of copper metal roofing systems are based on reported uplift tests for roof covering systems that have achieved UL 90 classifications, when tested to UL 1897 and or UL 580.
