ZIP SysteMO Roof & Wall Sheathing Installation Manual
ZIP Syltem® Sheathing Installation on Roofs
Overview: JkIP System Roof & Wall sheathing is composed of ZIP System panels and ZIP System seam sealing tape. ZIP System® Roof & Wall Sheathing
panels sho ld 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
o
on the roof o 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 11 he 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 installation process. These are manufacturer installation recommendations —please visit zipsystem.com for a library of flashing and installation details. You are
fully and solely responsible for all safety requirements. Good construction and safety practices should be followed at all times.
Step 1.
- Ensu that the panel surface is dry and clean of any nails, sawdust, or
other ebris or protrusions prior to installing or walking on the panels.
- After ensuring compliance with all OSHA and local code safety
guidc Ines, install ZIP System sheathing panels with the moisture
barri surface facing outside. The long edge (8') should be oriented
I �ldicular to the framing members, and panels should be installed
with he 4' edge seams staggered a minimum of 24".
- 1/8" 'acing between square edges of all adjacent panels is recommended,
in accordance with industry standards for wood sheathing. (Tongue &
Groo a panels are designed to self -space and do not require manual
spacing on the 8' edges.)
Step 2.
Enst e that ZIP System panels span at least three framing members and
a fra ing member supports the entire 4' edge of the panels.
Fast n the ZIP System Roof &Wall sheathing panel to the framing
me ers with code approved fasteners spaced at the appropriate
edg and intermediate spacing. It is the responsibility of the general
cont actor to verify proper fastener type and spacing prior to installation.
Applt the fasteners 3/8" from the panel ends and comers.
An ideal installation would be where fastener heads are flush with the
pan J�surface. However, due to variations in materials and limitations
on uipment, this may be difficult to achieve in some situations. It
is n required to tape over overdriven fasteners unless the fastener
hea creates a hole through the entire panel thickness. Please see
the chnical tip, "Overdriven Fasteners in ZIP System Roof and Wall
She lthinq," for more information.
Step 3.
Install t�mporary toe boards as necessary when applying the ZIP System
sheathi g panels up the slope of the roof planes.

ZIP Sy em'" Tape Installation - Roof Panel: Seams
Apply ZIP Ostem 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 se4os 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 Oigh 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 iscretion of the installer whether to apply tape from the top down
or fro the bottom up. However, working from the highest sections of
the r f and working down will minimize foot traffic on the tape.
- Ensu that the tape is centered over the seam within +/- 1/2" to provide
adeqi iate coverage and to ensure that wrinkles in the tape are minimized.
- Ensuill
that tape lengths are continuous across the 8' horizontal edge
of thanels. If splices are unavoidable, create an overlapping splice
of atst 3". Apply moderate pressure onto the surface of the tape to
ensua secure bond between the panel and the tape.
- Use IP System tape gun or tape roller to apply pressure to the tape
and ooth out any wrinkles.
- Take,special care to remove any voids and/or trapped air at splice
area and T-joints.
Step 2.
- For v [ley areas of framing, we recommend you use 6" wide ZIP System
tape. This tape is wider than panel seam tape and is designed to give you
opti 'hl protection in valley areas.
Start ng from the bottom and working your way up, apply one continuous
piec of 6" tape so that the center of the tape is over the valley seam.
- Use' a tape gun or tape roller to apply pressure to the tape to ensure
prop r contact with the panel and to eliminate any wrinkles that might
have�,occurred in the tape. Take special care to seat tape completely
into he valley.
Note:
- It is mportant to pay extra attention to valley taping as water is
dire ed toward the valleys during rain events.
- Self dhering ice and water barriers may be required by code. ZIP
Sys m tape is not considered a replacement for self -adhering ice
and ater barriers. Therefore, when self -adhering ice and water
barr rs are required, they should be installed in addition to ZIP
System tape.

installation instructions.
7. Cut a piece of rigid head flashing so that when
installed, it is flush with the edges of the exterior
moulding of the window. Apply a bead of sealant
to the back and bottom surface of the rigid
head flashing. Use sealant recommended by the
flashing manufacturer.
8. Secure the rigid head flashing to ZIP System
wall sheathing.
9. Cut a length of ZIP System tape or another
adhesive -backed flashing tape (must meet ICC-ES
Acceptance Criteria for Flashing Materials (AC148))
and apply to the rigid head flashing, ensuring
that the adhesive -backed flashing overlaps the
jamb flashings.
Once the tape is in place, use the tape gun or roller
to seal the flashing to the sheathing.
10. From the interior, apply low-pressure polyurethane
foam (for windows) between the rough opening and
the window frame. (Caulk sealant compatible with
the sill flashing may be used at the sill if the opening
between the sill flashing and window is too narrow
to allow the use of low-pressure polyurethane foam.)
When using ZIP System tape, butyl, 100%silicone
or polyurethane sealants are acceptable. Do not
use latex or other water -based sealants with ZIP
System tape. If using another flashing tape, follow
the flashing manufacturer's recommendation in
selecting a sealant compatible with that flashing.
