A cool roof covering for forming the outermost layer of a bituminous roof coating is provided, this cool roof covering comprising multiple heat-reflecting cap-sheets arranged in an adjacent, overlapping edge fashion and a heat-reflecting cap-sheet adhesive applied to overlapping portions of the cap-sheets for securing these cap-sheets to one another. The heat-reflecting cap-sheets exhibit a solar reflectance of at least 60% and a thermal emittance of at least 65. The heat-reflecting cap-sheet adhesive comprises a storage-stable, VOC-compliant mixture containing at least 10 wt. % of one or more weather-resistant organic resins dissolved in an organic solvent, the adhesive having a viscosity of 15,000 cps or less at 77&#xb0; F. (25&#xb0; C.) and exhibiting a lap shear strength of at least about 17 lbf/in when applied to a substrate and dried.

Cool roof covering and adhesive therefor

An apparatus (10) for applying fluid roof panel adhesive to a substrate includes a holding tank (12) for holding a supply of adhesive vertically above the substrate. The tank is supported by a pair of spaced wheels (14) and has a handle (16) to enable moving the device over the substrate. Openings (32) in a lower wall (30) of the tank enable adhesive to flow onto the substrate. Blocking members (36) associated with each opening are movable in response to the position of a lever (20) to enable or prevent flow of adhesive through the openings. Movement of the apparatus over the substrate provides for controlled deposition of uniformly spaced beads of adhesive suitable for holding roof panels to the substrate.

Adhesive application apparatus

The present invention relates to low slope roofing systems, particularly in commercial (as opposed to residential) roofing applications. More specifically, the fastener-free roofing system of the present invention is directed to the use of a curing adhesive composition which will simply and safely secure roofing insulation to a roofing deck without the need for mechanical fasteners.
