WESTERN LOCK® STANDING SEAM METAL ROOFING

Floating Unvented Ridge Cap - Part #WS-456

Floating ridge cap means that the standing seam panels aren't pinned in place at the ridge. This allows for expansion and contraction. If you have a floating ridge, you will need a fixed connection at the other end of the standing seam panel. 

Most of the jobs that we supply have a fixed ridge and a floating eave. This detail is not used that often.
