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.
STEP 1: Cut the post opening, slit to the
edge of the sheet, and apply adhesive.
STEP 2: Bond the sheet in
place, then clean the surface.
STEP 3: Tape one wall with 2” of the tacky
side folded out, extending 2” past the corner.
STEP 4: Unfold the tape
and bond it to the roof sheet.
STEP 5: Wrap the tape around the
stretching it to contact the roof and wall.
STEP 6: Tape the opposite wall the same
way, wrapping around the opposite corners.
STEP 7: Clean both tape surfaces
and apply tape on the third side.
STEP 8: Apply tape on the fourth side
and wrap around onto the first two sides.
STEP 9: Place a length of tape over
the slit and pull the release paper.
STEP 10: Roll all surfaces
firmly with a steel roof roller.
STEP 11: Caulk the perimeter of
the tape as well as the overlap seam.
