• Once the lightweight concrete is completely dry and has passed Dry Out

Acceptance test, provide a coat of the primer on the entire roof area including vertical sides of parapet wall and top and to the bottom of reglet (wherever required per site conditions). Prime the top and bottom of the metal flanges and concrete and masonry surfaces with a uniform coating of bituminous primer, at a nominal rate of 3.8 liters (1 gallon) per 9.29 square meters (100 sf.).

• Unroll base ply prior to installation and cut into 5-meter (15 feet) lengths. Allow membrane to relax prior to application.

• Align side lap of base ply over mid-point or center of roof drain.

• Prior to application, re-roll “relaxed” membrane approximately 2.5 meters (7-feet

6-inches). Lay all layers of roofing free of wrinkles, creases, or fishmouths. Exert sufficient pressure on the roll during the application to ensure the prevention of air pockets.

• Apply heat evenly across the face and full width of the roll while unrolling roll uniformly with an even downward pressure. Apply torch flame to the roll until the bitumen back coating reaches the design application temperature, resulting in melting of the burn-off film, a glossy appearance of the back coating, and an approximate 6mm (1/4-inch) to 13mm (1/2-inch) bitumen flow from the edge of the sheet. Repeat this process with the other end of this 5-meter (15feet) roll.

• Check lap seams and seal unbonded or discontinuous seams using a heated steel trowel.

3.6 Top Cap Membrane Installation - Smooth Surface Top Ply:

• Unroll top ply prior to installation and cut into 5-meter (15-feet) lengths. Allow membrane to relax prior to application.

• Align top ply centered over roof drain openings.

• Prior to application, re-roll “relaxed” membrane approximately 2.5 meters (7-feet

6-inches). Lay all layers of roofing free of wrinkles, creases, or fishmouths. Exert sufficient pressure on the roll during the application to ensure the prevention of air pockets.

• Beginning at the low point of the roof (roof drain) fully adhere membrane top ply to membrane base ply. Extend membrane top ply to top edge of cant. Stagger side laps of top ply a minimum of 300mm (12-inches) from side laps of base ply.

• Apply heat evenly across the face and full width of the roll while unrolling roll uniformly with an even downward pressure. Apply torch flame to the roll until the bitumen back coating reaches the design application temperature, resulting in melting of the burn-off film, a glossy appearance of the back coating, and an approximate 6mm (1/4-inch) to 13mm (1/2-inch) bitumen flow from the edge of the sheet. Repeat this process with the other end of this 5-meter (15-feet) roll.

• Roof Drain: Install top ply centered over roof drain opening extending under the clamping ring. Install clamping ring and secure.

• While installing membrane top ply, provide proper protection or method during application to prevent burning or charring on the surface of previously installed sheet.

• During end lap application, trim the inside corner along the selvage edge of the underlying sheet at the end of the roll. The trimmed area shall be the width of the selvage edge and extend downward from the end of the roll to the outer side of the roll on a linear direction approximately 138mm (5 ½-inches) from the end of the roll. Trim outside corner of membrane top ply at end laps to provide a rounded finished corner.

• Overlap the side laps a minimum of 100mm (4-inches) and end laps a minimum of 200mm (8-inches). Stagger end laps of adjacent sheets of membrane tope ply a minimum of 1 meter (3-feet). Extend field sheet of membrane top ply to top edge of cant.

• Check lap seams and seal unbonded or discontinuous seams using a heated steel trowel.

3.7 Base Flashing Application – Granular Surfaced Top Ply:

• Apply top ply of flashings only after membrane is in place.

• Cut the flashing from the rolls using selvage edge as lap seam for adjacent sheets resulting in sheet lengths of nominal 1 meter (3-feet). Stagger laps from laps of underlying plies.

150mm (6-inches) on-center. Apply three-coursing consisting of an initial continuous troweling of elastomeric plastic roof cement, embedded reinforcing fabric, and a secondary application of elastomeric plastic roof cement along and concealing the top edge of base flashing and termination bar.

• Apply membrane top ply and terminate at the rise in the metal component. Apply a continuous bead of edge sealant or molten modified compound along edge terminations of modified bitumen sheet (i.e. flashing flanges, exhaust vents, metal edge, etc.). Bead of edge sealant shall match height of granule surfacing and shall be “canted” to shed water. Embed loose granules, color to match to ply, into newly installed edge sealant.

• Curbs: Mechanically attach the top edge of flashing with appropriate fasteners and termination bar and secure 150mm (6-inches) on-center. If flashing sheet is wrapped over top of curb, secure to top or inside of curb with appropriate fasteners. For curbs with non-removable hoods/covers/units, extend flashing to full height of curb and apply three-coursing of plastic roof cement and reinforcing fabric. For curbs with removable hoods/covers/units, wrap flashing sheet over top of curb and secure to top or inside of curb with angle termination bar and appropriate fasteners spaced at 150mm (6-inches) on-center.

• Install flashing sheets on adjoining perpendicular sides (outside corners) of curbs or walls so that outside corners of flashing membrane sheet align and are rounded.

• Apply a boot or oval section modified bitumen sheet over outside corners of curb flashings to conceal cuts in flashing material at corner laps.

• Apply a three-coursing of elastomeric plastic roof cement and reinforcing fabric at vertical lap seams. Extend three-coursing under termination bar. Utilize masking or duct tape to create vertical straight edge of three-coursing. After application of three courses, remove tape. Embed granules into plastic roof cement, immediately after application, to achieve uniform base flashing color.
