3.3 INSTALLATION - GENERAL
A. Install modified bitumen membranes and flashings in accordance with manufacturer's
instructions and with the recommendations provided by the National Roofing
Contractors Association's Roofing & Waterproofing Manual, the Asphalt Roofing
Manufacturers Association, and applicable codes.
B. General: Avoid installation of modified bitumen membranes at temperatures lower than
40-45 degrees F. When work at such temperatures unavoidable use the following
precautions:
1. Take extra care during cold weather installation and when ambient temperatures are
affected by wind or humidity, to ensure adequate bonding is achieved between the
surfaces to be joined. Use extra care at material seam welds and where adhesion of
the applied product to the appropriately prepared substrate as the substrate can be
affected by such temperature constraints as well.
2. Unrolling of cold materials, under low ambient conditions must be avoided to
prevent the likelihood of unnecessary stress cracking. Rolls must be at least 40
degrees F at the time of application. If the membrane roll becomes stiff or difficult
to install, it must be replaced with roll from a heated storage area.
C. Commence installation of the roofing system at the lowest point of the roof (or roof
area), working up the slope toward the highest point. Lap sheets shingle fashion so as to
P a g e | 21 Bid # 2021-21-051B - Roofing
constantly shed water
D. All slopes greater than 2:12 require back-nailing to prevent slippage of the ply sheets.
Use ring or spiral-shank 1 inch cap nails, or screws and plates at a rate of 1 fastener per
ply (including the membrane) at each insulation stop. Place insulation stops at 16 ft
o.c. for slopes less than 3:12 and 4 feet o.c. for slopes greater than 3:12. On non-
insulated systems, nail each ply directly into the deck at the rate specified above. When
slope exceeds 2:12, install all plies parallel to the slope (strapping) to facilitate
backnailing. Install 4 additional fasteners at the upper edge of the membrane when
strapping the plies.

specified material at the rate of 25 to thirty 30 lbs. (11-13kg) per 100 square feet.

all side laps. Use care to eliminate air entrapment under the membrane. Exercise
care during application to eliminate air entrapment under the membrane.

3. Install subsequent rolls of modified membrane as above with a minimum of 4 inch
(101 mm) side laps and 8 inch (203 mm) end laps. Stagger end laps. Apply
membrane in the same direction as the previous layers but stagger the laps so they
do not coincide with the laps of the base layers.
4. Apply hot material no more than 5 feet (1.5 m) ahead of each roll being embedded.
