CAUTION All trapezoidal panels are extremely difficult to install at hips and valleys in a weathertight manner. The use of these details should only be attempted by installation crews that are highly experienced. In order to help ensure weathertightness, CHIEF recommends it’s MVF/MVP standing seam system for use on roofs that require hips and valleys.
