To fill an observed need in 
the roofing industry, Formtek Group Inc. is now manufacturing a w-valley die for rotorized vendors. This tool forms a w-style valley that is used primarily in asphalt shingle roofing but can be used in other types of pitched roofing applications as well. This new add-on or accessory tool is available now and is one of a number of additional applications for Roto-die.
Prior to this unveiling, big companies only made valley from the thinnest materials (35-30 gauge), which could be damaged while being installed on or transported on trucks. With Formtek’s w-valley die, these contractors don’t have to experience product losses on site or in transit.
