Cap sheet installation does not require a staggered end

4.9 PHASING
Phasing is when sections of roof are partially completed
and left exposed for a period of time before continuing or
surfacing.
Whenever practical, phasing of your roof system should
be avoided.
Phasing can occur during the installation of the base, ply,
cap, or surfacing.
Problems such as blistering,delaminating,physical abuse,
other trade damage, and water intrusion can result from
phased roofing.
Incomplete sections of exposed base or ply sheets can
also accumulate dirt or contamination on its surface, and
can affect the bond between the adhesive and the rest of
the built up roofing membranes.
Any areas that are damaged due to phased roofing must
be repaired in a manner that is acceptable to Malarkey
before continuing the roof installation.
