1.1 GENERAL

  1. The roofing assembly / material information published by the RCABC Roofing Practices Manual does NOT represent a complete set of the manufacturer's published data, nor does it represent a detailed specification. The preparation of a detailed specification is the responsibility of the design authority.
    1. SYSTEM DESCRIPTION
      1. Three-ply roof membranes: the first two plies consists of a type IV or Type VI glass felt; applied with hot asphalt; the second ply consists of a cap sheet applied with hot asphalt, cold adhesive or heat welding.
    2. PROJECT CONDITIONS
      1. Do not apply roofing insulation or membrane to damp deck surface.
      2. Do not expose materials subject to water or solar damage in quantities greater than can be weatherproofed during same day.
      3. All slopes greater than 2:12 (17%) require back-nailing to prevent slippage of the ply sheets. Use ring or spiral-shank one (1) inch (25 mm) cap nails, or screws and plates at a rate of one (1) fastener per ply (including the membrane) at each insulation stop. Place insulation stops as per RGC Guarantee Standards (Section 2,1,1)). On non-insulated systems, nail each ply directly into the deck at the rate specified above. When slope exceeds 2:12 (17%), install all plies parallel to the slope (strapping) to facilitate backnailing. Install four (4) additional fasteners at the upper edge of the membrane when strapping the plies.
    3. MANUFACTURER’S SERVICES
      1. Applicator training: Garland membranes are applied by GARLAND APPROVED APPLICATORS ONLY.
      2. Technical service: technical representatives are available for consultation and field training; owners, architects, and engineers are assisted in the selection and proper use of Garland materials by technical representatives.
      3. Specification / Drawings: complete specifications and detail drawings are available upon request.

1.3 EXECUTION

    1. PREPARATION
      1. Ensure membrane substrate is rigid, dry, smooth, compatible, free of fins and sharp edges, and clean of all
      2. Ensure all openings, walls, and projections through the roof are firmly affixed and cant strips, reglets and nailing strips are in place.
      3. A thermal barrier may be required between the roof deck and some insulations. Building code and insurance requirements to be identified by design authority.
    2. PRIMER
      1. Prime wood, concrete, and metal surfaces to be directly adhered with bituminous membranes; allow to dry.
    3. APPLICATION INSTRUCTION FOR A THREE-PLY SYSTEM
      1. FELT PLY INSTALATION (THREE-PLY SYSTEM) HOT ONLY
        1. Fiberglass Plies: Install two (2) fiberglass ply sheets in twenty five (25) lbs (11.3kg) per square of bitumen shingled uniformly to achieve two plies over the entire prepared substrate. Shingle in direction of slope of roof to shed water on each area of roof. Do not step on felt rolls until asphalt has cooled, fish mouths should be cut and patched.
        2. Lap ply sheet ends eight (8) inches (203mm). Stagger end laps twelve (12) inches (304mm) minimum.
        3. Lightly broom in fiberglass plies to assure complete adhesion.
        4. Extend plies two (2) inches (50mm) beyond top edges of cants at wall and roof projections and equipment bases.
        5. Install base flashing ply to all perimeter and projection details after membrane application.
      2. MODIFIED MEMBRANE INSTALATION HOT OR COLD
        1. Solidly bond the modified membrane to the base layers with specified asphalt or cold adhesives at the rate of twenty five (25) to thirty (30) lbs. (11-13kg) per 100 square feet.
        2. The modified membrane roll must push a puddle of asphalt in front of it with asphalt or cold adhesives slightly visible at all side laps. Exercise care during application to eliminate air entrapment under the membrane.
        3. Apply pressure to all seams to ensure that the laps are solidly bonded to substrate.
        4. Install subsequent rolls of modified membrane across the roof as above with a minimum of four (4) inch (101mm) side laps and eight (8) inch (203mm) end laps. Stagger the end laps. Apply the modified membrane in the same direction as the previous layers but stagger the laps so they do not coincide with the laps of the base layers.
        5. Apply asphalt or cold adhesives no more than five (5) feet (1.5m) ahead of each roll being embedded.
      3. FLASHING MEMBRANE INSTALLATION
        1. Seal all curb, wall and parapet flashings with an application of mastic and mesh on a daily basis. Do not permit conditions to exist that will allow moisture to enter behind, around or under the roof or flashing membrane.
        2. Prepare all walls, penetrations, expansion joints [and where shown on the drawings] to be flashed with asphalt primer at the rate of one hundred (100) square feet per gallon (2.1square m per litre). Allow primer to dry tack free.
        3. Use the modified membrane as the flashing membrane. Adhere to the underlying base flashing ply with specified asphalt unless otherwise noted in these specifications. Nail off at a minimum of eight (8) inches (203mm) o.c. from the finished roof at all vertical surfaces.
        4. Solidly adhere the entire sheet of flashing membrane to the substrate.
        5. Seal all vertical laps of flashing membrane with a three-course application of trowel-grade mastic and fiberglass mesh.
        6. Coordinate counter flashing, cap flashings, expansion joints, and similar work with modified bitumen roofing work.
        7. Coordinate roof accessories, miscellaneous sheet metal accessory items, including piping vents and other devices with the roofing system work.
