ABSTRACT:
An improved roof flashing comprising a hard base frustroconical base member and a elastomeric sealing collar, wherein the interconnection between the collar and base member is through overmolding a ring mount assembly, 6, that is characterized by a substantially horizontal upper surface and a pair of downwardly extending first and second legs, 12, 14. The proximate end of the sealing collar has a substantially horizontal upper surface and a pair of concentric lower surfaces, substantially coplanar but separated by the extending bottom of the second downward leg, 14. In this fashion, a bending moment supplied about a second downward leg, 14, through wiping action at the distal end of the elastomeric collar, 42, will not tend to separate the elastomeric collar from the frustroconical member, 4, at points radially outward from the second downward leg, 14.
