ROOF SHEATHING // COMMON DETAIL
ALTERNATIVE DETAILS // TAPING ROOF VALLEYS
If 6" ZIP System
™
tape is not available, use two continuous pieces
of 3-3/4" ZIP System
™
tape over the entire length of the valley
seam, overlapping the pieces on the valley seam by at least 1".
Starting from the bottom, install the first piece of tape overlapping
the valley seam by at least 1". Roll the tape to apply pressure to the
tape to ensure proper contact with the panel and to eliminate any
wrinkles that might have occurred in the tape. Apply the second
piece of tape, overlapping the first piece in the valley seam by
1". Roll the tape to apply pressure and the tape is adequately
adhered and tightly pressed into the valley seam. It is important
to pay extra attention to valley taping as water is directed toward
the valleys during rain events.
