Abstract: A trolley carrying a roll of vapor retarder fabric is supporting on building roof purlins and moved along the purlins as the fabric is dispensed onto the purlins under longitudinal tension. Fabric tension is maintained to inhibit sagging thereof between the purlins by applying one braking force to the fabric roll and another braking force between the trolley and the purlins. The trolley has a rectangular support frame with opposite sides and front and rear ends. Rotatable rollers adjacent the rear end movably support the frame on the purlins, and a friction brake adjacent the front end engages the purlins. A handle attachment adjacent the rollers receives a handle for tilting the frame about the rollers to release the frame brake and push the trolley along the purlins. A frame guide roller extends downwardly from the front end of the frame for engaging a side of a purlin to prevent skewing of the frame relative to the purlins.

Abstract: A composite roofing material includes a final condition underlayment material having bonded thereto appropriate rows of nail tabs preferably made of thermoplastic-based material, such as low density polyethylene material, and of a contrasting color to the underlayment material. A process is used to make the nail tabs by conveying the saturated underlayment material in a continuous process past appropriate sets of nozzles that are coordinated with the speed of conveyance to deposit the tabs while in a liquid state and to form tabs of appropriate size and appropriately patterned across the underlayment surface. Each nozzle can include multiple orifices to control the width and thickness of the formed tabs. A similar process is disclosed for making other building cover materials having rows of nail tabs coinciding with standard stud spacing.

The method comprises discontinuously coating a hydrophobic foam in strips onto one side of a nonwoven film-fibril sheet to form a composite structure. The composite structure, preferably the foam side, is positioned against the outside surface of the framing structure of a building such that the foam strips align with the studs of the building. The facing material is then secured by one or more fastening elements through the composite structure. The nonwoven sheets with foam strips provide resistance to air infiltration and liquid penetration between the interior of the building and the surrounding environment.

Abstract: A process for sealing roof seams in a corrugated sloped metal roof comprises applying elongated strips of a flexible hot melt thermoplastic bituminous composite material to the seams and the edges of the roof surface immediately adjacent thereto but not over the whole roof surface. The bituminous composite material has an elevated operating temperature of about 500.degree.-600.degree. F. or greater. The bituminous composite material is heated to at least a point wherein the material becomes soft and semi-molten so as to conform to the surface of the roof and the convolutions of the corrugations and bonds to the roof surface.

Abstract: A method of restoring lapped metal roofs of, for example, steel or aluminum, and consisting of side-by-side panels having side and end edges which overlap to form edge joints, wherein the terminal edge of one panel is an exposed edge which extends over and overlies the edge of an adjacent panel to form an elongated joint, and wherein fasteners extend through the lapped panels to secure the panels together and in place. The method involves applying a flexible, formable rubber to cover the exposed terminal edges of the panels along their lengths. The rubber strips adhere to the panels and are stretchable with temperature-induced expansion and contraction of the panels. Similar strips are applied over all exposed fasteners, and then a substantially non-elastic asphaltic coating is applied over the strips and roof panels to bond to each. With temperature-induced relative movement of the roof panels, the coating cracks and separates and moves with the elastic strips as they stretch.
