I have a commercial grade EPDM, Single Ply Membrane roof on my house (Flat Roof). We are looking to put PV solar panels on the roof to lower our energy costs. The sales people for the solar wanted to just anchor the PV panels into the roof joists and seal the pentrations with sealant. I feel that is unacceptable and will void my roof warranty. I am trying to connect the roofer with the PV people. To get the proper flashing instalation.
I think the right solution is to build a curb with the proper flashing / counterflashing wrapping the EPDM up the curb. This would be similar to the way HVAC units are installed and flashed on commercial buildings. Has anyone here done this or have any pertinent advice?
