The Residential Retrofit Pipe Flashing is an EPDM retrofit pipe flashing for use on a shingle roof. The Flashing fits pipes with an outside diameter from 1/4" - 5 3/8". The retrofit seal can be easily closed by using a pair of pliers to crimp tight up to 10 stainless steel clips (included with flashing). M-1 Structural Adhesive is recommended for bonding the flashing to the pipe and roofing material.
