1.5.3
Handling
Prevent damage to edges and ends of roll materials. Damaged materials
shall not be installed in the work. Select and operate material handling
equipment so as not to damage materials or applied roofing. Do not use
materials contaminated by exposure or moisture. Remove contaminated
materials from the site. When hazardous materials are involved, adhere to
the special precautions of the manufacturer. Adhesives may contain
petroleum distillates and may be extremely flammable; prevent personnel
from breathing vapors, and do not use near sparks or open flame.
1.6
ENVIRONMENTAL REQUIREMENTS
Do not install EPDM sheet roofing during high winds or inclement weather,
or when there is ice, frost, moisture, or visible dampness on the substrate
surface, or when condensation develops on surfaces during application.
Unless recommended otherwise by the EPDM sheet manufacturer and approved by
the Contracting Officer, do not install EPDM sheet when air temperature is
below 4 degrees C (40 degrees) F or within 3 degrees C (5 degrees F) of the
dewpoint. Follow manufacturer's printed instructions for installation
during cold weather conditions.
1.7
SEQUENCING
Coordinate the work with other trades to ensure that components which are
to be secured to or stripped into the roofing system are available and that
permanent flashing and counterflashing are installed as the work
progresses. Ensure temporary protection measures are in place to preclude
moisture intrusion or damage to installed materials. [Application of
roofing shall immediately follow application of insulation as a continuous
operation. Roofing operations shall be coordinated with insulation work so
that all roof insulation applied each day is covered with roof membrane
installation the same day.]
1.8
WARRANTY
Provide roof system material and workmanship warranties meeting specified
requirements. Revision or amendment to standard membrane manufacturer
warranty shall be provided as required to comply with the specified
requirements.
