Roofing apparatus

A portable apparatus for cementing edges of lengths of sheet material in adherent relationship over a roof, said apparatus being effective for sealing even the edges of sheet material located adjacent to an upstanding perimeter wall about a roof, and having the following structural features in locations with respect to an imaginary vertical plane as specified:

• a. a horizontally oriented base structure having contact means at its lower surface for applying pressure upon said sheet material, said base structure being adjacent to and extending laterally outwardly from only one side of said imaginary vertical plane, said base structure having a leading edge and a trailing edge located in spaced relationship to each other at spaced locations along said imaginary vertical plane,
• b. an applicator assembly for applying cementing fluid underneath an edge of said sheet material, said applicator assembly being located forwardly beyond the leading edge of said base structure, with all elements of said applicator assembly lying on the same side of said imaginary vertical plane as said base structure, said applicator assembly comprising a brush member consisting essentially of a substantially flat layer of bristles held at their heel end by a substantially flattened ferrule having an angular section at the portion thereof adjacent said heel end of said bristles, said angular section of said ferrule being at an angle with respect to the main body of said ferrule so that said flat layer of bristles projects laterally away from one lateral side of said main body, the angular configuration between said main body and said bristles of said brush member being between about 90.degree. and 140.degree.,
• c. bracket means mounted on said base structure and extending forwardly beyond the leading edge thereof, said bracket means comprising a ferrule holder for holding said main body of said ferrule in vertical orientation at a location substantially parallel and adjacent to said imaginary vertical plane, said main body of said flattened ferrule being held in said ferrule holder with said bristles of said brush member extending from the lower end and extending laterally from said main body in a direction away from said imaginary vertical plane,
• d. a fanned nozzle mounted on said apparatus for discharge of cementing fluid within said angular configuration of said brush member,
• e. conduit means carried by said base structure for conveying cementing fluid to said fanned nozzle,
• f. valve means for controlling the flow of cementing fluid through said conduit means, and
• g. handle means mounted on said base structure for an operator to guide said base structure in movement in a direction substantially parallel and adjacent to said imaginary vertical plane, said apparatus being free of any element which projects laterally outward therefrom beyond said imaginary vertical plane at any location along the side thereof adjacent said imaginary vertical plane.
