NOTE
12" Valley dimension must be used in low slope conditions and in valleys longer than 30'-0".

CAUTION

All trapezoidal panels are extremely difficult to install at hips and valleys in a weather tight manner. The use of these details should only be attempted by installation crews that are highly experienced. In order to assure weather tightness, ASBC recommends one of it’s vertical leg standing seam systems for use on roofs that require hips and valleys.
