ABSTRACT:
A roof flashing structure for use in forming a seal around a pipe on either flat roofs or roofs pitched at various common angles can be constructed utilizing a generally flat, imperforate plate having a centrally located opening. Such a plate carries an upstanding, imperforate housing extending outwardly from one side of the plate, this housing terminating in an open end located remote from the plate of larger dimension than the pipe. An annular retainer is carried by this end of the housing; a resilient elastomeric sealing member is carried by the retainer. This sealing member engages the exterior of the pipe in such a manner as to form a seal against the pipe, and in such a manner as to permit the plate to be adjusted relative to the pipe so as to fit against either a flat roof or a roof at any commonly used pitch. The plate, the housing and the retainer are preferably formed integrally with one another out of a sheet of ABS material laminated to a surface covering of a degradation resistant acrylic composition.
