Protecting your valleys is very important and often overlooked. Valleys are usually shaded at least partially by one of the adjacent ridges allowing snow and ice to build up as the rest of the roof melts faster.
All this buildup can spell trouble to your valley pans and roof panels if not protected (see images below). There are 2 ways to address this.

1. The most common is to stair-step along the valley covering 2 to 4 panels per step depending upon the severity of slope and loads.
Example 1. Stepping up the valleys using ColorGard®
2. The second method is to install the ColorGard system parallel to the valley on both sides. In the latter case, SnoClip should not be used.
Example 2. Running up the valleys using the S-5! ColorGard® with VersaClips
