Standing Seam roof over rigid insulation

Guest User
Can the metal roof concealed clips be installed directly onto the R-19 (3.1" thick) rigid insulation or is a sub-purlin recommended? Thanks

This depends on the type of standing seam. Some types can be installed over insulation using longer screws into the clips while others can not. Also it can depend on the type of insulation, for example some rigid type insulations are sandwiched between plywood which can be fastened into. You will need to check with the manufacturer of your particular type of standing seam.

That type of installation typically uses "bearing plates" under the clips. As stated above you should check the manufactures details.
