ZIP SYSTEM
®
SHEATHING // NOTES & LIMITATIONS
Do not use on roofs with slopes less than 2/12.
Do not use abutted against general stone or masonry
without providing a minimum of a 1/2" gap.
ZIP System products are not recommended for
manufactured housing applications that are built
under a federal building code administered by the
U.S. Department of Housing and Urban Development
(HUD).
Do not use ZIP System
™
tape to permanently seal
around circular roof projections (plumbing vents,
pipes, curved walls, etc.)
When original roofing is removed and replaced on
existing ZIP System
®
sheathing, the roof should be
covered with an additional roofing underlayment prior
to installation of the new finished roofing or cladding.
In roofing systems requiring multiple layers of water-
resistive barriers, like clay tile, ZIP System
®
sheathing
is intended to replace only the first layer.
