ZIP Systeme Sheathing Installation on Roofs
Overview: ZIPI 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 root sheathing panels should be installed from the lowest point
on the roof to 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 thereof and working down will minimize foot traffic 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 zipsystem corn for a library of flashing and installation details. You are
My and solely 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 debris or protrusions prior to installing or walking on the panels.
After ensuring. compliance with all OSHA and local code safety
guidelines, install ZIP System sheathing panels with the moisture
barrier surface facing oulside The long edge (8') should be oriented
perpendicular to the framing members, and panels should be installed
with the 4�' edge seams staggered a minimum of 24%
18' spacing between square edges of all adjacent panels is recommended,
in accordance with industry standards for wood sheathing. (Tongue &
Groove panels are designed to self -space and do not require manual
spacing on the 8' edges,)
Step 2.
Ensure that ZIP System panels span at least three framing members and
a framing,member supports the entire 4' edge of the panels.
Fasten thIe 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 toverify proper fastener type and spacing prior lo installation.
Apply ihe,lasteners 318' from the panel ends and comers.
An ideal installation would be where fastener heads are flush 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 tip, "Overdriven Fasteners in ZIP System Roof and Wall
Sheathing," for more information.
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 System tape after all ZIP System Roof & Walt sheathing panels are fully fastened to mol-framing members. Only ZIP System tape should be used to
seat the seams of ZIP System panels. Ensure that the panel surfaces are dry and free of any naits, 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.
Step 1.
ApplyZIP'System tape to every vertical and horizontal panel seam. His
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 traffic on the tape.
Ensure that the tape is centered over the seam within +r- 1?2- to provide
adequate coverage and to ensure that wrinkles in the tape are minimized.
Ensure that tape lengths are continuous across the B' horizontal edge
of the panels. If splices are unavoidable, create an overlapping splice
of aI leash 3'. App:y moderate pressure onto the surface of the tape to
ensure a secure bond between the panel and the tape
Use ZIP System tape gun or tape miter to apply pressure to the tape
and smooth out any wrinkles.
Take special care to remove any voids andior trapped air at splice
areas and T-joints.
Step 2.
For valley areas of tram ng, we recommend you use 6' wide ZIP System
tape This tape is wider 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 of 6' tape so that the center of the tape is over the valley seam
Use the tape gun or tape roller 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
directed 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 self -adhering ice and water
barriers are required, they should be installed In addition to ZIP
System tape.
