We often get asked about how to lay out snow retention in valleys. 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. The most common is to stair-step along the valley covering 2 to 4 panels per step depending upon severity of slope and loads. 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 1. Stepping up the valleys

Example 2. Running up the valleys using the S-5! ColorGard with VersaClips
