          PART 3EXECUTION
 
          3.1DELIVERY, STORAGE, AND HANDLING IMPORT
 
          A.New and dry roof materials delivered to the job site in containers unopened and undamaged. Manufacturer's products stamped with labels, names and run codes of manufacture and testing laboratory.
 
          B.Store underlayment materials on ends only. Discard rolls which may have been flattened, creased, or otherwise damaged. Place materials on pallets or wood sleepers. Do not stack palletized materials.
 
          C.Cover underlayment rolls with weatherproof materials secured to prevent materials from becoming exposed to moisture. Use breathable tarps.
 
          D.Disperse materials stored on the roof surface to avoid concentrated loading. Set larger concentrations over structural members.
 
          3.2ENVIRONMENTAL REQUIREMENTS
 
          A.Application of roofing materials shall not be performed when weather conditions interfere with good roofing practices.
 
          3.3VENTED NAILBASE AND BASE INSULATION
 
          A.Install base insulation and vented nailbase so the joint of the base insulation and the joints of the nailbase are offset.
 
          B.Fastener placement and spacing shall be in accordance with the recommendations of the insulation panel manufacturer.
 
          3.4UNDERLAYMENT AND EDGING
 
          A.Apply specified underlayment laid parallel to eaves, lapping as follows:
          ** NOTE TO SPECIFIER ** Delete type not required.
          1.Self-adhering underlayment along all eaves and rakes extending to a point beyond the interior surface of exterior walls not less than 24 inches.
          2.Slopes of 4 units in 12 units or greater Apply SBS modified fiberglass underlayment laid parallel to eaves, lapping to the four inch ply line, and six (6) inches on ends, lapping over self-adhered underlayment a minimum of 6 inches.
          3.Slopes of less than 4 units in 12 units, apply self-adhering underlayment of the entire roof surface.
          4.Slopes of less than 4 units in 12 units, apply two layers of specified underlayment installed shingle fashion with 50% side laps and 6" end laps staggered 24".
 
          B.Valleys: Only those valley installations listed in the manufacturer's installation recommendations shall be permitted.
          1.One additional layer of self-adhering underlayment shall be applied in all valleys, regardless of the valley method used.
          2.The field underlayment shall be applied through the valley over the additional layer of self-adhering underlayment from both slopes forming the valley.
 
          C.Pipe Flashing: Apply a cant of roofing cement around the pipe, sealing it to the underlayment prior to installing the metal pipe flashing. Install and secure the metal jack so that the bottom flange laps over onto the shingles. Side and top flanges shall have shingles lapping onto the flange. Shingles that lap onto metal shall be laid into a bed of roof cement. A bead of urethane sealant shall be applied where the pipe penetrates the cone of the jack.
 
          D.Metal edging: Minimum 24 gauge (0.70 mm) rigid, pre-finished metal with no rise. Install the edging onto the underlayment along the rake edges and below the underlayment along the eave edges, secured by galvanized roofing nails four inches (102 mm) O/C. Metal edge with a 1/2 inch (13.4 mm) the underlayment overhanging drip built into the face is acceptable.
 
          3.5APPLICATION OF SHINGLES
 
          A.Application; 5-5/8 inches (143 mm) Offset- Diagonal Pattern:
          1.Starter courses: Use only the approved starter strip.
          2.Cut six inches (152 mm) off the length of the starter strip and apply at the corner roof. The starter course shall overhang the edge metal 1/4 to 3/8 inch (6 mm to 9.5 mm). Nail starter within four inches (102 mm) of the edge of the roof with the same number of nails specified for the field shingles.
          3.Continue starter course across the roof with a full length shingle with the tabs cut off.
          4.First course: Start with a full shingle applied onto and flush with the starter course at the lower left hand corner of the roof and secure with fasteners.
          5.Second course: Cut 5-5/8 inches (143 mm) in from the left end of a shingle and apply the remaining 34-3/8 inches (873 mm) section over the first course shingle, exposing the first course 5-5/8 inches (143 mm). Butt bottom edge of shingle should be applied to the top of saw tooth of underlying shingle so that there will be 5-5/8 inches (143 mm) of each shingle exposed, secure with fasteners.
          6.Third courses: Cut 11-1/4 inches (285.75 mm) from the left end of shingle and apply the remaining 28-3/4 inches (730 mm) section over the second course shingle, exposing the second course 5-5/8 inches (143 mm), secure with fasteners.
          7.Succeeding Courses: Courses four through seven are begun with a partial 5-5/8 inches (143 mm) shingle shorter progressively, establishing the overall diagonal method or stair step effect. (Pieces cut from shingle along the left rake, can be used to finish off courses at the right rake.)
          8.Now apply a full shingle to the seven courses to extend the pattern starting with the first course. Courses eight through fourteen repeat the process beginning with a full shingle and continue succeeding courses with a partial 5-5/8 inches (143 mm) shingle shorter each time. Succeeding courses also repeat this procedure beginning with a full shingle. Strike a chalk line about every six courses to ensure straight courses. Shingles may be laid either left or right hand side. Start at either rake edge and follow layout and cutting instructions as required for proper application. Fill-in pieces less than three inches (76 mm) in width are not acceptable at rake edges.
 
          B.Valley Installation:
          1.Closed-cut Valleys: Apply shingles on one entire face, carrying each course up through the valley and onto the adjoining face a minimum twelve inches (305 mm). Secure each shingle no closer than six inches (152 mm) in from the center of the valley.
          2.Open Valleys: Shall use corrosion resistant rigid sheet metal valley material, a minimum of twenty four inches (610 mm) wide, pressed tight into the valley and secured twelve inches (305 mm) O/C along both edges. As shingles are applied, trim neatly approximately two inches (51 mm) back from center of valley.
          3."Bleeder" or "Point" valleys are not acceptable.
 
          3.6FASTENERS
 
          A.Nailing Pattern: Nails must be placed within the nailing zone, 1 inch (25 mm) in from each edge of the shingle, with the remaining four nails evenly spaced on the same line as the end nails. When fastening, butt shingle ends loosely to prevent buckling. Fasteners shall not be overdriven to cut into the shingle or under driven. Fasteners shall be seated flush to shingle as illustrated on shingle wrapper.
          ** NOTE TO SPECIFIER ** Delete fastener quantity not required.
          1.Fasteners per Shingle: Four.
          2.Fasteners per Shingle: Five (Windsor only).
          3.Fasteners per Shingle: Six.
          4.Fasteners per Shingle: Nine (Windsor only).
