          B.Eaves:
          1.Place eave edge metal flashing tight with fascia boards; lap joints 2 inches (50 mm) and seal with plastic cement; nail at top of flange.
          ** NOTE TO SPECIFIER ** Delete the following paragraph if the conditions described do not apply.
          2.On roofs with slope between 2:12 and 4:12, and on all roofs in the north, install leak barrier up the slope from eave edge to 36 inches from the edge or at least 24 inches (610 mm) beyond the interior face of the warm exterior wall, whichever is greater; lap ends 6 inches (150 mm) and bond.
 
          C.Valleys:
          1.Install leak barrier at least 36 inches wide centered on valley; lap ends 6 inches (150 mm) and seal.
          2.Where valleys are indicated to be "open valleys", install metal flashing over leak barrier before roof deck underlayment is installed; DO NOT NAIL THROUGH flashing; secure by nailing at 18 inches (457 mm) on center just beyond edge of flashing so that nail heads hold down edge.
 
          D.Roof Deck:
          1.Install one layer of roof deck underlayment over entire area not protected by eave or valley membrane; run sheets horizontally lapped so water sheds; nail in place.
          ** NOTE TO SPECIFIER ** Delete one of the next two paragraphs, unless both slopes are included in project.

          3.At skylights and roof hatches, install leak barrier up the sides of the frame and 12 inches (305 mm) on to the roof surface on all sides, lapping over roof deck underlayment.
          4.At chimneys, install leak barrier around entire chimney extending at least 6 inches (150 mm) up the wall and 12 inches (305 mm) on to the roof surface lapping over roof deck protection.
          ** NOTE TO SPECIFIER ** The following leak barrier locations are OPTIONAL. Delete if not required.
          5.At rake edges, install metal edge flashing over leak barrier and roof deck protection; set tight to rake boards; lap joints at least 2 inches (50 mm) and seal with plastic cement; secure with nails.
          6.At hips and ridges, install leak barrier along entire lengths. If ridge vents are to be installed, position the leak barrier so that the ridge slots are not covered.
 
          3.5INSTALLATION OF SHINGLES
 
          A.Install in accordance with manufacturer's instructions and requirements of local building code.
          1.Avoid breakage of shingles by avoiding dropping bundles on edge, by separating shingles carefully (not by "breaking" over ridge or bundles), and by taking extra precautions in temperatures below 40 degrees F (4 degrees C).
          2.Handle carefully in hot weather to avoid damaging shingle edges.
          3.Secure with 4 to 6 nails per shingle; use number of nails required by manufacturer or by code, whichever is greater. Nails must be long enough to penetrate through plywood or OSB, or 3/4 inch (19 mm) into dimensional lumber.
 
          B.Install hip and ridge shingles as required by the manufacturer.
          1.At ridges, install hip and ridge shingles over ridge or ridge vent material.
          ** NOTE TO SPECIFIER ** Delete all but one of the following three styles of valleys. Open valleys and closed cut valleys are suitable for all styles of shingles. Woven Valleys are only acceptable with Sentinel, Royal Sovereign, Marquis Weathermax and Slateline Shingles.
 
          C.Make valleys using "open valley" technique:
          1.Snap diverging chalk lines on metal flashing, starting at 3 inches (75 mm) each side of top of valley, spreading at 1/8 inch per foot (9 mm per meter) to eave.
          2.Run shingles to chalk line.
          3.Trim last shingle in each course to match chalk line; do not trim shingles to less than 12 inches (305 mm) width.
          4.Apply 2 inches (50 mm) wide strip of plastic cement under ends of shingles, sealing to metal flashing.
 
          D.Make valleys using "closed cut valley" technique:
          1.Run the first, and only the first, course of shingles from the higher roof slope across the valley at least 12 inches (305 mm).
          2.Run all courses of shingles from the lower roof slope across the valley at least 12 inches (305 mm) and nail not closer than 6 inches (150 mm) to center of valley.
          3.Run shingles from the upper roof slope into valley and trim 2 inches (50 mm) from center of valley.
 
          E.Make valleys using "woven valley" technique:
          1.Run shingles from both roof slopes at least 12 inches (305 mm) across center of valley, lapping alternate sides in a woven pattern.
          2.Nail not closer than 6 inches (150 mm) to center of valley.
 
          F.At skylights, chimneys and other penetrations, shingle up to and around the opening or penetration prior to installing the appropriate flashing. Install flashing and shingles in accordance with manufacturer's standard instructions for skylights, chimneys and penetrations.
 
          3.6VENTILATION

          1.Cut continuous vent slot through sheathing, stopping 6 inches (150 mm) from each end of ridge.
          2.On roofs without ridge board, make slot 2 inches (50 mm) wide, centered on ridge.
          3.On roofs with ridge board, make two slots 1-3/4 inches (89 mm) wide, one on each side.
          4.Install ridge vent material full length of ridge, including uncut areas.
          5.Butt ends of lengths of ridge vent material and join using plastic cement.
          6.Install eave vents in sufficient quantity to equal or exceed the ridge vent area, calculated as specified by manufacturer.
          7.Install ridge shingles over ridge vent material; use nails of specified length; do not drive nails home, leaving 3/4 inch (19 mm) slot open between ridge and roof shingles.
 
          B.Roof Louvers:
          1.Cut vent hole through sheathing as specified by the manufacturer for the type of vent to be installed.
          2.Install a 24 inches (610 mm) square of leak barrier, centered around the hole
          3.Install according to manufacturer's instructions for flashing vent penetrations
          4.Install eave vents in sufficient quantity to equal or exceed the exhaust vent area, calculated as specified by manufacturer.
 
          C.Powered Ventilators:
          1.Cut vent hole through sheathing as specified by the manufacturer for the type of vent to be installed.
          2.On rooftop applications, install a 36 inches (610 mm) square of leak barrier, centered around the hole
          3.Install according to manufacturer's instructions for flashing vent penetrations
          4.Install eave vents in sufficient quantity to equal or exceed the exhaust vent area, calculated as specified by manufacturer.
 
          3.7PROTECTION
 
          A.Stage work progress so that traffic is minimized over completed roofing.
 
          B.Protect installed products until completion of project.
