PART 3: EXECUTION

3.1	PREPARATION

A.	Deck shall be firm, dry, clean, and properly graded to all outlets.  Secure a wood strip of same thickness as insulation adjoining all eaves to act as a stop for insulation.
3.2	INSTALLATION ‑ NAILABLE DECKS

A.	Cover deck with one layer of rosin sized sheathing paper, lapping a minimum of 1 inch; nail in place.

B.	Apply one layer of felt, overlapping 6 inches; nail through laps at 6‑inch centers and down longitudinal center of each felt using two rows of nails spaced 10 inches apart and staggered on 18‑inch centers. Use nails or fasteners as recommended or appropriate to type of deck.  Turn felt up, but do not cement, on all vertical surfaces to height of 6 inches.  Overhang of felt at roof edges, 6 inches.

C.	Apply units of insulation with long joints continuous and short joints staggered.  Place long edges of insulation at right angles to boards of deck.  Mop full width under each unit using hot asphalt at a minimum rate of 30 pounds per square per layer on insulation.  Apply asphalt at temperatures between 350 and 425 degrees F.

D.	Before application of roofing, turn projecting 6 inches of felt over insulation at all edges and vertical surfaces; mop solidly with asphalt.

3.3	INSTALLATION ‑ CONCRETE DECKS

A.	Coat deck with primer as recommended by insulation manufacturer.

B.	Apply one layer of felt, overlapping 6 inches; mop full width under each felt with asphalt at a minimum rate of 23 pounds per square.  Turn felt up, but do not cement, on all vertical surfaces to height of 6 inches.  Overhang of felt at roof edges, 6 inches.

C.	Apply units of insulation with long joints continuous and short joints staggered.  Mop full width under each insulation unit with asphalt at a minimum rate of 30 pounds per square per layer of insulation. Apply asphalt at temperatures between 350 and 425 degrees F.  If insulation manufacturer recommends application in more than one layer, apply succeeding layers using same procedure as for first layer.  Stagger all joints between layers.

D.	Before application of roofing, turn projecting 6 inches of felt over insulation at all edges and vertical surfaces; mop solidly with asphalt.

E.	Where incline requires nailing of roof felts, 2-inches and over for each foot of smooth surface roofs, or 1-inch and over for each foot of gravel surfaced roofs, provide wood nailing strips at ridge and intermediate points, maximum of 20‑foot centers.  Run nailing strips, same thickness as insulation, horizontally to receive insulation and retain nails securing felts.  Where incline is 3-inches and over for each foot, install nailing strips 4‑1/4 feet from inside face to inside face.

3.4	INSTALLATION ‑ STEEL DECKS

A.	If deck surface requires primer to ensure bond between deck and adhesive, coat with primer as recommended by insulation manufacturer.

B.	Apply one layer of felt, overlapping 6 inches; mop full width under each felt with asphalt at minimum rate of 23 pounds per square.  Turn up edges of felt, but do not cement, at all vertical surfaces to height of 6 inches.  Overhang of felt at roof edges, 6 inches.

C.	Apply units of insulation with long joints continuous, either parallel or at right angles to ribs of metal deck.  Stagger end joints.  Place any joint parallel to ribs over solid deck bearing.  Mop full width under each unit of insulation with asphalt at a minimum rate of 30 pounds per square per layer of insulation.  Apply asphalt at temperatures between 350 and 425 degrees F.  Where vapor barrier is not used, mop with asphalt at rate of between 12 and 25 pounds per square.  When cold adhesive is required, apply each unit of insulation in 1/2‑inch‑wide ribbons of approved adhesive.  Apply adhesive to top bearing surface of steel deck.
D.	If insulation manufacturer recommends application in more than one layer, apply succeeding layers using same procedure as for first layer.  Stagger all joints between layers.

E.	Before application of roofing, turn projecting 6 inches of felt over insulation at all edges and vertical surfaces; mop solidly with asphalt.
