          PART 3  EXECUTION     [BACK TO TOP]
          3.1 EXAMINATION
          A. Do not begin installation until substrates have been properly prepared.
          B. If substrate preparation is the responsibility of another installer, notify Architect of unsatisfactory preparation before proceeding.
          3.2 PREPARATION
          A. Clean surfaces thoroughly prior to installation.
          B. Prepare surfaces using the methods recommended by the manufacturer for achieving the best result for the substrate under the project conditions.
          3.3 INSTALLATION
          A. Follow manufacturer's current installation guidelines, procedures found in the current version of the National Roofing Contractors Association's (NRCA) "Steep Slope Roofing and Waterproofing Manual", and requirements of all code bodies having jurisdiction. In the event of a conflict in installation requirements, the more stringent method of installation will prevail.
          ** NOTE TO SPECIFIER ** Delete flashing conditions not present on this project from the next eight conditions. While not required by most building codes, installation of weather barrier at hips, ridges and rake edges is strongly recommended by most roofing manufacturers and the NRCA.
          B. Roof Deck: Starting at the lowest point of the roof section, apply one layer of underlayment horizontally over all sections of roof deck not protected by eave or valley membrane and nail in place. Lap horizontal edges 2 inches (51 mm). Overlap ends at least 4 inches (102 mm); stagger end laps at least 36 inches (915 mm) apart.
          C. Eaves: Place eave edge metal flashing tight with fascia boards; lap joints 2 inches (50 mm) and seal; nail at top of flange.
          D. Valleys: Install a full width of weather barrier centered on valley; lap ends 6 inches (150 mm) and seal. Where open valley construction is specified, install metal flashing over weather barrier before roof deck underlayment is installed. Lap underlayment over valley protection at least 6 inches (150 mm).
          E. Vent Pipes and Field Penetrations: Apply a 24 inch (610 mm) square target sheet of weather barrier around the penetration. Lap over underlayment beneath and at the sides of the penetration and beneath underlayment above the penetration. Apply sealant to the seam above the penetration.
          F. Sidewalls, Headwalls and Chimneys: Apply weather barrier extending at least 8 inches (203 mm) up the wall and 12 inches (305 mm) on to the roof surface. Lap over roof deck protection.
          G. Hips and Ridges: Apply weather barrier over the length of the hips and ridges. Where ridge ventilation is specified, remove weather barrier from areas where ventilation slots are required prior to installing ridge vent.
          H. Rake Edges: Apply weather barrier and underlayment prior to installation of any rake edge flashing. Apply sealant to the edge prior to installation of metal flashing and nail metal edge flashing every 6 inches (152mm).
          I. Skylights: Apply weather barrier up the sides of the frame and 12 inches (305 mm) on to the roof surface on all sides, Lap over underlayment beneath and at the sides of the skylight and beneath underlayment above the penetration. Apply sealant to the seam above the skylight. See skylight manufacturer for any additional installation details.
          3.4 PROTECTION
          A. Protect installed products until completion of project.
          B. Touch-up, repair or replace damaged products before Substantial Completion.
