PART 3 EXECUTION
3.1 EXAMINATION
A. Do not begin installation until substrates have been properly prepared.
B. Inspect and approve the deck condition, slopes and fastener backing if applicable, parapet walls, expansion joints, roof drains, stack vents, vent outlets, nailers and surfaces and elements.
C. Verify that work penetrating the roof deck, or which may otherwise affect the roofing, has been properly completed.
D. If substrate preparation and other conditions are the responsibility of another installer, notify Architect of unsatisfactory preparation before proceeding.
3.2 PREPARATION
A. General: Clean surfaces thoroughly prior to installation. 1. Prepare surfaces using the methods recommended by the manufacturer for achieving
the best result for the substrate under the project conditions. 2. Fill substrate surface voids that are greater than 1/4 inch wide with an acceptable fill
material. 3. Roof surface to receive roofing system shall be smooth, clean, free from loose gravel,
dirt and debris, dry and structurally sound. 4. Wherever necessary, all surfaces to receive roofing materials shall be power broom
and vacuumed to remove debris and loose matter prior to starting work. 5. Do not apply roofing during inclement weather. Do not apply roofing membrane to
07550-11
damp, frozen, dirty, or dusty surfaces. 6. Fasteners and plates for fastening components mechanically to the substrate shall
provide a minimum pull-out capacity of 300 lbs. (136 k) per fastener. Base or ply sheets attached with cap nails require a minimum pullout capacity of 40 lb. per nail.
7. Prime decks where required, in accordance with requirements and recommendations of the primer and deck manufacturer.
B. Precast concrete: 1. Decks shall be clean, dry, fully cured and free of flaws and attached securely to the
supporting structure as recommended by the deck manufacturer. 2. All joints shall be caulked or grouted. 3. Concrete surfaces to receive roofing shall be fully primed at the rate of 1 gallon per
100 sq. ft. 4. When applying roofing or insulation directly to the deck with asphalt, prime with
asphalt/concrete primer, ASTM D41, at a rate of 1 gal/square (.4 L/m2) and allow the primer to dry prior to the application of the roofing system. Hold back bitumen at the joints approximately 4 inches (102 mm) to prevent bitumen drippage.
5. Deck joints shall be stripped in with a 12 inch (305 mm) wide strip of modified membrane unadhered a minimum of 2 inches (51 mm) immediately on either side of the joint.
C. Re-Roofing Applications: 1. Remove existing roofing from curbs and parapet walls down to the surface of the
concrete roof deck. Remove existing flashings at roof drains and roof penetrations. 2. Remove all wet, deteriorated, blistered or delaminated roofing membrane or insulation
and fill in any low spots occurring as a result of removal work to create a smooth, even surface for application of new roof membranes.
3. Install new wood nailers as necessary to accommodate insulation/recovery board or new nailing patterns.
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 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
07550-12
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.
