Overview: IP System Roof & Wall sheathing is composed of ZIP System panels and ZIP System seam sealing tape. ZIP System® Roof & Wall Sheathing
panels should be fully installed before the seam sealing tape is applied. In general, the ZIP System roof sheathing panels should be installed from the lowest point
on the roof t the highest. It is at the discretion of the installer whether to apply tape from the top down or from the bottom up. However, working from the highest
sections of t e roof and working down will minimize foot traffic on the tape. The following installation steps are presented as guidelines and a general outline of
the instaflat' , n process. These are manufacturer installation recommendations —please visit zipsystem.com fora library of flashing and installation details. You are
fully and sol Jy responsible for all safety requirements. Good construction and safety practices should be followed at all times.
Step 1.
- EnsurE that the panel surface is dry and clean of any nails, sawdust, or
other c ebris or protrusions prior to installing or walking on the panels.
- After nsuring compliance with all OSHA and local code safety
guidelif I tes, install ZIP System sheathing panels with the moisture
barrier gicular
urface facing outside. The long edge (8') should be oriented
perpe to the framing members, and panels should be installed
with th 1 4' edge seams staggered a minimum of 24".
- 1/8" sp Icing between square edges of all adjacent panels is recommended,
in acc �rdance with industry standards for wood sheathing. (Tongue &
G roov4 panels are designed to self -space and do not require manual
spacin I on the 8' edges.)
Step 2.
Ensurl that ZIP System panels span at least three framing members and
a frami g member supports the entire 4' edge of the panels.
Fastei the ZIP System Roof & Wall sheathing panel to the framing
memb rs with code approved fasteners spaced at the appropriate
edge : nd intermediate spacing. It is the responsibility of the general
contra for to verify proper fastener type and spacing prior to installation.
Apply ne fasteners 3/8" from the panel ends and corners.
An ideal installation would be where fastener heads are flush with the
panel urface. However, due to variations in materials and limitations
on eq ipment, this may be difficult to achieve in some situations. It
is not equired to tape over overdriven fasteners unless the fastener
head Ireates a hole through the entire panel thickness. Please see
the technical tip, "Overdriven Fasteners in ZIP System Roof and Wall
Sheat ing," forpore information.
Step 3.
Install to porary toe boards as necessary when applying the ZIP System
sheathinl', panels up the slope of the roof planes.

ZIP SystemT" Tape Installation - Roof Panel Seams
Apply ZIP S stem tape after all ZIP System Roof & Wall sheathing panels are fully fastened to roof -framing members. Only ZIP System tape should be used to
seal the seal s of ZIP System panels. Ensure that the panel surfaces are dry and free of any nails, sawdust and other debris, or protrusions. Avoid stepping
on tape in f'jgh temperature environments. ZIP System tape is a contact tape that requires pressure for an adequate seal.
Step 1.
Apply IP System tape to every vertical and horizontal panel seam. It is
at the liscretion of the installer whether to apply tape from the top down
or fro the bottom up. However, working from the highest sections of
the ro V and working down will minimize foot traffic on the tape.
Ensur that the tape is centered over the seam within +/- 1/2" to provide
adequate coverage and to ensure that wrinkles in the tape are minimized.
Ensur that tape lengths are continuous across the 8' horizontal edge
of the panels. If splices are unavoidable, create an overlapping splice
of at I ast 3". Apply moderate pressure onto the surface of the tape to
ensur a secure bond between the panel and the tape.
Use Z IP I System tape gun or tape roller to apply pressure to the tape
and smooth out any wrinkles.
Takelnd
pecial care to remove any voids and/or trapped air at splice
areas T-joints.
Step 2.
For val ey areas of framing, we recommend you use 6" wide ZIP System
tape. is tape is wider than panel seam tape and is designed to give you
optim protection in valley areas.
Starti g from the bottom and working your way up, apply one continuous
piece IIIII f 6" tape so that the center of the tape is over the valley seam.
Use tl tape gun or tape roller to apply pressure to the tape to ensure
propeE contact with the panel and to eliminate any wrinkles that might
have ccurred in the tape. Take special care to seat tape completely
into t i valley.
Note: I,I
- It is 1111 portant to pay extra attention to valley taping as water is
direc ed toward the valleys during rain events.
Self-hering ice and water barriers may be required by code. ZIP
Syste tape is not considered a replacement for self -adhering ice
and % ater barriers. Therefore, when self -adhering ice and water
barrb rs are required, they should be installed in addition to ZIP
