EPDM ROOFING:  POSTS

Posts have four outside corners and are flashed with a procedure similar to that described in TAPED OUTSIDE CORNERS. Uncured Laminate Tape, a 6” wide self-adhesive lamination of uncured EPDM rubber and Butyl seam tape, is applied to each of the four sides of the post and stretched around the corners. In cold weather, a hot air gun or hair dryer should be used to help stretch the tape. If the posts are set in from the roof edge, the rubber roof sheet must be slit and then patched.
