Fixed Valley - Part #WS-425

Fixed valley means that the standing seam panels will be pinned in place at the valley. If you have a fixed point at the valley, you will need a floating connection at the other end of the standing seam panel.

Most of the jobs that we supply have a floating valley. This detail is not used that often.

Valley trim is a raised section at the lowest part of the valley that's designed to keep water from moving up the opposite slope and penetrating the roof. Valley trim is installed prior to the installation of the metal roofing panels. The valley of a metal roof is an area created by two intersecting slopes.

When snow accumulations begin to melt, the result can be catastrophic as the blanket of snow avalanches off the roof dumping tons of snow onto anything in its path.

It can damage landscape, gutters, adjacent roofs, vehicles and cause injury or death to passers-by. All of S-5!’s snow retention systems dramatically reduce these risks associated with rooftop avalanches while maintaining the clean lines of the roof.
