ZIP System® Sheathing Installation on Roofs
I
Overview: ZIP System Roof & Wall sheathing is composed of ZIP System panels and ZIP System seam sealing tape. ZIP System Roof & Wall Sheathing
panels sho IId 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 roof111 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 the roof and working down will minimize foot trait on the tape. The following installation steps are presented as guidelines and a general outline of
the installation process, These are manufacturer installation recommendations —please visit zipsyslem com for a library of flashing and installation details. You are
fully and soleIly responsible for all safety requirements. Good construction and safely practices should be followed at all times.
i Step 1.
Ensur that the panel surface is dry and clean of any nails, sawdust, or
other cIebris or protrusions'prior to installing or walking on the panels.
After ensuring compliance with all OSHA and local code safety
guidel es, mstali ZIP System sheathing panels with the moisture
barrier surface facing outside The tong edge (8) should be oriented
perpe dicular to the framing members, and panels should.be installed
with thlI 4' edge seams staggered a minimum of 24",
11/8'sp wing between square edges of all adacent panels is recommended,
to accordance with industry standards for wood sheathing. (Tongue &
Groove panels are designed to setf•space and do not require manual
spacrnb on the 8' edges,)
Step 2. 1
Ensure that ZIP System panels span at least three framing members and
a fra*g member supports the entire 4' edge of the panels.
Fastenithe ZIP System Roof & Wall sheathing panel to the framing
members with code approved fasteners spaced at the appropriate
edge and intermediate spacing. It Is the responsibility of the general
contractor to verify proper fastener type and spacing prior to installation.
Apply the fasteners 318' from the panel ends and comers.
An ideal installation would be where fastener heads are Ilush with the
panel surface However, due to variations in materials and limitations
on equipment, this may be difficult to achieve in some situations It
is not required to tape over overdriven fasteners unless the fastener
head creates a hole through the entire panel thickness. Please see
the technical lip, "Overdriven Fasteners in ZIP System Roof and Wall
i Sheathing," for more information.
i I
Step 3.
Install temporary toe boards as necessary when applying the ZIP System
sheathing panels up the slope of the roof planes.

ZIP System" Tape Installation - Roof Panel Seams
Apply ZIP gystem tape after all ZIP System Roof & Wak sheathing panels are fully fastened to roof -framing members. Only ZIP Sysiem tape should be used to
seal the seams 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 High temperature environments, ZIP System tape is a contact tape that requires pressure for an adequate seal.
j Step 1. LP
Apply System tape to every vertical and horizontal panel seam. It is
at the discretion of the installer whether to apply tape from the top down
or froT the bottom up. However, working from the highest sections of
the mIf and working down will minimize foot traffic on the tape.
Ensurs that the tape is centered over the seam within +t- VZ,to provide
adequate coverage and to ensure that wrinkles in the tape are minimized.
Ensure that tape lengths are continuous across the 8` horizontal edge
of the panels. If splices are unavoidable, create an overlapping splice
of at least 3'. Apply moderate pressure onto the surface of the tape to
ensur� a secure bond between the panel and the tape
Use ZIP System tapir gun or tape rafter to apply pressure to the tape
and smooth out any wrinkles.
Take special care to remove any voids and;or trapped air at splice
areas and T-joints.
Step 2. 1
For valley areas o1 framing, we recommend you use 6- wide ZIP System
tape T�ls tape is wader than panel seam tape and is designed to give you
optimal protection in valley areas.
Starting from the bottom and working your way up. apply one continuous
piece o16' tape so that the center of the tape is over the valley seam
Use the tape gun or tape roper 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. Take special care to seat tape completely
into the, valley.
Note:
- It is important to pay extra attention to valley taping as water is
directsd toward the valleys during rain events.
Self -adhering ice and water barriers may be required by code. ZIP
System tape is not considered a replacement for self -adhering Ice
and water barriers. Therefore, when sell -adhering ice and water
barriers are required, they should be installed In addition to ZIP
Systerq tape.
