ABSTRACT:
A roof flashing structure of the type having a generally flat plate with an upstanding housing integrally attached thereto can be improved by forming the upmost periphery of said housing such that it has an inner wall and an outer wall with a channel in between these walls. An elastomeric sealing member has a support wall with a plurality of annular pipe sealing flanges extending from said support wall. Also attaching to the support wall is a skirt which extends downward from the annular wall. The skirt is shaped and dimensioned to mimic the shape of the interior of the channel. The skirt is attached to the channel via mechanical locking passageways in conjunction with a thermal bonding. The thermal bond is formed by a process wherein the elastomeric sealing member is molded into the housing using a compatible plastic for the housing and a compatible rubbery material for the sealing member.
