PART 3 EXECUTION

3.1 PRE-ROOFING MEETING

Not less than 3 days prior to the start of the roofing work, contractor shall schedule a pre-roofing meeting. This meeting shall include the Contracting Officer's Representative, government inspector, designer, and coating manufacturer's representative. Items that shall be prepared to discuss are schedule of the work, material storage areas, safety measures, protection of building components not to receive roofing materials, inspection methods, method of installation and points of contact in emergencies.

3.2 SURFACE EXAMINATION

Verify that all surfaces are ready to receive work. Roof surfaces shall be clean, dry, structurally sound, stable and well secured. The roof surface shall be free of excessive ponding water. A roof surface that allows standing water 48 hours after a rain shall be considered unacceptable. All water shall be allowed positive drainage from the roof.

Inspect condition of flashing details adjacent to protrusions, penetrations, roof mounted equipment, curbs, walls, parapets, drains and roof edge to ensure that details are acceptable and will maintain a weather-tight installation after being properly detailed and coated. Inspect parapets to ensure that concrete, masonry or metal caps are sound. Caulk, reinforce or replace as necessary in order to bring parapet and parapet cap into a weathertight condition. Determine moisture content of existing substrate, insulation and deck. A moisture content of 15 percent or greater indicates a potential problem. Work shall not proceed until the cause of high moisture content is verified and condition is corrected.

3.3 SURFACE PREPARATION

3.3.1 BUILT-UP ROOFING SUBSTRATE

3.3.1.1 All loose gravel, dirt and debris shall be removed by vacuuming and/or power sweeping. Roofs exhibiting heavily embedded gravel must be made smooth for acceptance of the fluid-applied roof coating system using one of the following methods:

A. Removal of the protruding gravel by spudding, scraping or scarifying the surface as necessary to create a smooth, acceptable surface. Take care to preserve the integrity of the existing asphalt membrane whenever possible.

B. Application of a flood-coat of asphaltic emulsion in sufficient quantity so as to encapsulate and bury the protruding gravel, creating a smooth, acceptable surface.

C. Application of an approved roof recovery board, as per manufacturer's instruction, so as to create a smooth, acceptable surface.

3.3.1.2 Roof deck areas shall have positive slope-to-drain. Tapered insulation, cant strips, spray-applied polyurethane foam or other similar materials shall be used to build up affected roof surfaces as necessary to provide adequate slope-to-drain.

3.3.1.3 Inspect parapets to ensure that concrete, masonry, wood or metal caps are sound.

Caulk, reinforce or replace as necessary in order to bring parapet and parapet cap into a weathertight condition using an approved single- component urethane sealant.

3.3.1.4 Severely deteriorated flashings shall be removed and either replaced, or repaired utilizing spray-applied polyurethane foam. Seal reglet conterflashings with single-component urethane sealant.

3.3.1.5 Any unsound areas in the roof deck or insulation, including blisters, delamination, deterioration, excessive moisture content, etc. shall be repaired or replaced.

All blisters, delaminations, wrinkles and loose areas shall both be cut away and removed, or cut open and nailed flat to the deck.

3.3.1.6 All built-up roofing surfaces shall be cleaned using an approved, biodegradable cleaner, following manufacturer's instructions. Rinse thoroughly with fresh water under high pressure to remove the solution from the roof and achieve a "jet black" clean surface. Heavy deposits of dirt or contamination may require agitation with a stiff-bristle broom or similar mechanical scrubber. Allow the roof to dry thoroughly.

3.3.1.7 If the roof has been previously coated with aluminized asphalt of any kind, a penetrating primer must be applied to prevent potential "leafing" of the surface. Consult coatings manufacturer prior to application of the acrylic coating system over aluminized asphalt surfaces.

3.3.1.8 Reinforce repaired areas by encapsulating reinforcement fabric into the encapsulation coat over the repair. Cut a strip of reinforcement fabric (width depending on the size of the detail) to the desired length, and center it over the detail area. Apply encapsulation coat liberally from the top side using a brush or roller, working the encapsulation coat into the fabric so as to eliminate air pockets, wrinkles and gaps.

Ensure that the reinforcement fabric is thoroughly saturated, encapsulated and fully adhered to the substrate.

3.3.1.9 All cracks, splits, voids or holes larger than 3 mm (1/8 inch) in width shall be filled and leveled using an approved single-component urethane caulk or acrylic mastic.

Heavy alligatoring or rough texture in the existing built-up roofing shall be leveled by applying a flood-coat of approved asphalt emulsion, in sufficient quantity so as to achieve a smooth surface.
