WESTERN LOCK® STANDING SEAM METAL ROOFING

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.

WS-425 - FIXED VALLEY - PARTS LIST

This parts list is designed to help you calculate the quantity of accessories that you’ll need for your trim installation. It has all of the accessories that are needed to install 1 full piece of trim, which is 120" long. To calculate the total number of accessories you will need for your job, simply take the number of trim pieces associated with the trim part purchased and multiply the list by that number for a total for your project.
