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.

SECTION 075200

MODIFIED BITUMINOUS MEMBRANE

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 (6.35 mm) 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 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 91 lbs. per nail.

7. Prime decks where required, in accordance with requirements and recommendations of the primer and membrane manufacturer.

B. Metal Deck: deck shall be installed as specified in Section

1. Fastening of the deck should comply with the anticipated live and dead loads pertaining to the building as well as applicable Code.

2. When re-roofing over metal decks, any surface deflection and any needed repairs to severely corroded areas shall be reported to the Architect and Owner. Loose, compromised, rotted or inadequately secured decking shall be repaired, fastened, and irreparable or otherwise defective decking shall be replaced.

C. Poured reinforced concrete:

1. Shall be smooth, dry, clean, and free of ice/frost, projections, and depressions. Concrete shall be fully cured, and the surface shall be broom cleaned and free of release/curing agents prior to commencement of work.

2. Prepared concrete surfaces for roofing or insulation by priming with asphalt/concrete primer conforming to ASTM D 41. Apply at a rate of approx. 1 gallon/100 sq. ft. (.4 L/m2). All primed areas shall be fully dried before proceeding with the application of the roof system. Hold back bitumen at the joints approximately 4 inches (101.6 mm) to prevent bitumen drippage.

D. Gypsum:

1. Gypsum decks shall be smooth and free from deflections or ridges.

2. An average fastener withdrawal resistance as recommended by the fastener manufacturer shall be obtained; however, at no time shall it be less than 91 lbs. per fastener.

3. Wet or frozen poured gypsum decks are not suitable to receive a roof.

4. Poured-in-place gypsum roof decks contain a large percentage of moisture. All necessary precautions shall be taken to avoid the entrapment of moisture under the roofing system.

In addition to ventilation of the underside to allow for proper curing, topside and perimeter venting shall be implemented.

5. Install a mechanically attached base sheet prior to installation of insulation or roofing membrane. Base or ply sheets attached with cap nails require a minimum pullout capacity of 91 lbs. per nail.

SECTION 075200

MODIFIED BITUMINOUS MEMBRANE

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 Fahrenheit (7.22 degrees Celsius). 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 Fahrenheit (4.44 degrees Celsius) 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 (25.4 mm) 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 (121.92 cm) 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.

3.4 INSTALLATION HOT APPLIED ROOF SYSTEM (Base Bid)

A. Vapor Barrier Ply(s): Install a vapor barrier ply to properly prepared decking substrates prior to installing subsequent system layers. Metal deck substrates shall receive a self-adhering air barrier/vapor retarder for roof applications. Gypsum, concrete or other types of decking shall receive a nailable vapor barrier sheet, fastened or adhered according to manufacturer’s specifications and recommendations.

1. Overlap head laps a minimum of 6 inch (152.4 mm). Overlap side laps a minimum of 3 inch (76.2 mm). as indicated by the lap lines on the product.

2. If the ply has been used as a temporary roof and is expected to function as a air barrier in a finished roofing system, it must be inspected by the manufacturer and repaired as needed.

3. All damaged areas must be cut out and removed, and new membrane installed in those areas.

4. When the roof system is installed over the self-adhering sheet, the insulation must be attached by mechanically fastening it into the structural deck.

SECTION 075200
