Revision as of 19:15, 10 August 2016
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.
Zinc Standing Seam metal roofing systems must meet or exceed RGC Guarantee Standards and must be installed to zinc manufacturers published roof system specifications. In addition, approved proprietary underlayment, insulation overlays and metal panel separation sheets must be installed and comply to zinc manufacturers published roof system specifications.
1 WORK INCLUDED
- (1) Membrane Pre-stripping
- RoofStar-accepted self-adhered modified bituminous membrane.
- (2) Ice and Water Protection / Insulation Overlay
- For slopes 2:12 to 4:12 use RoofStar-accepted self-adhered modified bituminous membrane.
