A. No. Good roofing practice utilizes the closed valley method for better function as well as a much nicer looking roof. ValleyFlash is designed for use in the closed valley applications. Although ValleyFlash is an innovative and superior quality product, ValleyFlash functions best when covered and protected from prolonged exposure to the sun.
