PART 3 - EXECUTION

3.1 GENERAL INSTALLATION REQUIREMENTS

A. Cooperate with manufacturer, inspection and test agencies engaged or required to perform services in connection with installing the roof system.

B. Apply adhesive in accordance with manufacturer recommendations.

C. Adhesive Mopping Rate:

1. Interply Mopping: Apply adhesive at the rate of approximately 2-2.5 gallons per roof square.

2. Modified Membrane Mopping: Apply adhesive at the rate of approximately 4-5 gallons per roof square.

D. Substrate Joint Penetrations: Prevent adhesive from penetrating substrate joints, entering building, or damaging roofing system components or adjacent building construction.

E. Apply roofing materials as specified by manufacturer's instructions.

1. Keep roofing materials dry before and during application.

2. Do not permit phased construction.

3. Complete application of roofing plies, modified sheet and flashing in a continuous operation.

4. Begin and apply only as much roofing in one day as can be completed that same day.

F. Cut-Offs (Waterstops): At end of each day's roofing installation, protect exposed edge of incomplete work, including ply sheets and insulation. Provide temporary covering of two (2) plies of #15 organic roofing felt set in full moppings of adhesive with joints and edges sealed.

G. Broadcast minerals into the bleed out of adhesive in accordance with manufacturer recommendations.

3.2 BASE PLY INSTALLATION

A. Install (1) one base sheet in 2 to 2.5 gallons per square of adhesive shingled uniformly to achieve one ply over the entire prepared substrate. Shingle in direction of slope of roof to shed water on each area of roof. Do not step on base rolls until adhesive has set, fish mouths should be cut and patched.

B. Lap ply sheet ends eight (8) inches (203mm). Stagger end laps twelve (12) inches (304mm) minimum.

C. Extend plies two (2) inches (50mm) beyond top edges of cants at wall and roof projections and equipment bases.

D. Install base flashing ply to all perimeter and projection details after membrane application.

3.3 MODIFIED MEMBRANE APPLICATION

A. Solidly bond the modified membrane to the base layers with specified adhesive at the rate of approximately 4to 5 gallons per 100 square feet.

B. The modified membrane roll must push a puddle of adhesive in front of it with adhesive slightly visible at all side laps. Exercise care during application to eliminate air entrapment under the membrane.

C. Apply pressure to all seams to ensure that the laps are solidly bonded to substrate.

D. Install subsequent rolls of modified membrane across the roof as above with a minimum of four (4) inch (101mm) side laps and eight (8) inch (203mm) end laps. Stagger the end laps. Apply the modified 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.

E. Apply adhesive no more than five (5) feet (1.5m) ahead of each roll being embedded.

F. Extend membrane two (2) inches (50mm) beyond top edge of all cants in full moppings of the specified adhesive.

3.4 FLASHING MEMBRANE INSTALLATION

A. Metal Edge:

1. Inspect the nailer to assure proper attachment and configuration.

2. Run one ply over the edge. Assure coverage of all wood nailers. Fasten plies with ring shank nails at eight (8) inches o.c.

3. Install continuous cleat and fasten at six (6) inches o.c.

4. Install new metal edge hooked to continuous cleat and set in bed of roof cement.

Fasten flange to wood nailer every three (3) inches o.c. staggered.

5. Prime metal edge at a rate of one hundred (100) square feet per gallon and allow to dry.

6. Strip in flange with base flashing ply covering entire flange in bitumen with six

(6) inches on to the field of roof. Assure ply laps do not coincide with metal laps.

7. Install a second ply of modified flashing ply in bitumen over the base flashing ply, nine (9) inches on to the field of the roof.

3.5 APPLICATION OF SURFACING

A. Reflective Coating:

1. Paint all exposed membrane with manufacturer's Energy Star acrylic coating installed at a rate of one (1) gallon per square per coat in a two coat application.

B. Mineral Surfaced Membrane System: While bleed out from the side and end laps are still hot, hand broadcast minerals into adhesive bleed out for a monolithic appearance.

Apply mineral lap sealant to any areas of improper adherence of minerals and rebroadcast minerals while coating is still wet.

3.6 FINAL INSPECTION

A. At completion of roofing installation and associated work, meet with Contractor, installer, roofing system manufacturer's representative, and other representatives directly concerned with performance of roofing system.
