;PART 3 - EXECUTION

;3.1 <u>PREPARATION</u>
:.1 The deck must be properly designed and constructed to support and secure the BURM 360 roof system.
:.2 The surface to which the roofing system is to be installed must be smooth, clean and dry.
:.3 Ensure wood blocking, curbs and cant strips are solidly secured and reglets and nailing strips are in place as required.
:.4 Prepare substrate in accordance with good roofing practices as outlined by RGC for the different deck types.

;3.2 <u>VAPOUR RETARDER</u>
:.1 Vapour retarders must be continuously extended throughout the roof plane. All openings in the roof deck must be flashed at the retarder level.
:.2 Options dependent upon specific job requirement:
:* Install Tremco vapour retarder with 50 mm (2") side laps and 100 mm (4") end laps, adhering with Tremco Insulation Adhesive or Fas’N’Free Adhesive.

;3.3 <u>INSULATION</u>
:.1 Mechanically fasten insulation over nailable decks in accordance with <i>RGC Guarantee Standards.</i>
:.2 Embed insulation in a ribbon application of Tremco Insulation adhesive at the rate of 0.019 litres per square metre (0.66 gallons / 100 sq ft) or Fas’N’Free Adhesive at the rate of 0.043 litres per square metre (1.5 gallons / 100 sq ft) over non-nailable decks.
:.3 Install 11 mm (7/16") asphalt coated fibreboard as insulation overlay, as required by <i>RGC Guarantee Standards</i>.
:.4 Install wood nailing strips on slopes exceeding 2:12 (2" in 12").

;3.4 <u>MEMBRANE APPLICATION</u>
:Install two plies of smooth (180 gram / sqm) polyester reinforced modified bitumen, laid in shingle fashion and placed to ensure that water will flow over or parallel to, but never against, exposed edges.
:.1 Prior to placement cut modified bitumen in 5 to 6 metre (16’ to 20’) lengths. Allow lengths to relax at least 30 minutes at 13°C (55°F) or above. Allow approximately 60 minutes to relax at temperatures below 13°C (55°F).
:.2 Starting at the low point of the roof, install two plies of smooth modified bitumen. Lap ends 150 mm (6").
:.3 Stagger all laps 300 mm (12").
:.4 Dry roll each ply to ensure proper alignment, prior to adhering with Burmastic
:.5 Immediately embed each ply in uniform applications of Burmastic, spray or brush applied at 0.8 litres per sqm (2 gallons / 100 sq.ft) per ply.
:.6 Fit plies into roof drain rims, reinforce with elastomeric sheeting adhered with Sheeting Bond.
:.7 Extend plies only to top edges of cant strips along bases of parapets, walls and skylights.

;3.5 <u>FLASHINGS</u>
:.1 Ensure continuity of air / vapour seal at all changes in direction.
:.2 Install one ply of Tremco Elastomeric Sheeting in Sheeting Bond Adhesive or alternatively, install 2 plies of modified bitumen adhered in Brush Grade Mastic Adhesive, S.F. Polyroof, Ecomastic or Sheeting Bond.
:.3 Ensure that flashing extends onto roof membrane a minimum of 150 mm (6") and terminates a minimum of 200 mm (8") above roof membrane.
:.4 Mechanically fasten flashing membrane 200 - 300 mm (8" - 12") on centre along outside fascia and along upper edge of wall flashing.
:.5 Install metal counterflashing or apply One-Coat Aluminium as a protective reflective coating at the rate of 0.8 litres / sqm (2 gallons / 100 sq ft).

;3.6 <u>PROTECTIVE FINISH</u>
:.1 Gravel Surface:
::Apply Burmastic at 2.4 litres / sqm (6 gallons / 100 sq ft) and immediately broadcast 20 kg / sqm (400 lb / 100 sq.ft) of new, clean pea gravel.
