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". This flashing is recommended for use on roofs with a pitch of 15° to 45° (3 on 12 to 12 on 12). This flashing can be used on roofs with more or less slope than the recommended range by making a special cut instead of using the factory cutting marks (installation by a roofing professional is recommended in this case). The retrofit seal closes easily by using a pair of pliers to crimp tight the stainless steel clips provided with each flashing.
