Abstract: An improved roof and method wherein each course of slate is underlain with an interlayment material layer such that the interlayment material acts as a base to the through joints, resulting in a reduction in the amount of slate used by approximately 40% to 50%. The slate meets side to side (the through joint), the underlaying interlayment material providing sufficient waterproofing to protect the roof as well as being of lighter weight and a more economical slate roof than the slate which it replaces.

Abstract: A composite drainage mat for preventing water and moisture from remaining trapped within walls and roofs of buildings which includes a weather barrier fixedly attached to a three-dimensional matrix filamentatious mat of a thermoplastic polyamide resin such as Nylon 6. The mat contains a great number of voids for permitting gas and liquid such as water to flow therethrough. The mat possesses a crush-resistance which allows the mat to withstand the compressive force of other building materials without inhibiting the ability of the mat to allow liquids and gases to flow therethrough.

Abstract: An asphalt composition ridge cover providing a three dimensional character to a roof. The ridge covers are manufactured and packaged in an approximately 90 degree "V" shape so as to require very little bending during installation. Adhesive holds the angle formed during manufacture. The ridge cover may have a thickening member or members thereunder giving the ridge covers a tapered thickness which, when installed, gives the resulting roof a pronounced three dimensional appearance.

Abstract: This invention is a method for sealing pitched shingled roofs. The object is to minimize the cost associated with sealing a roof against standing water such as the case with an ice dam. The method involves placing a continuous waterproof membrane over existing roofing shingles and placing the new shingles on the membrane. The membrane is self adhesive on one side, which is used to adhere to the existing shingles. It is further durable enough to withstand the forces between layers of shingles and thin enough so not to present torque problems with the fasteners used to affix the new shingles to the roof substrate.

Abstract: An insulation sheet having first and second layers of facing; and a sheet of foam material laminated between the first and second layers of facing. A portion of the first layer of facing extends beyond an edge of the sheet of foam material to form a strip. The strip has an adhesive applied on one side of the strip.

Abstract: A shingle and a method of applying the same to a roof is disclosed, in which the shingles are wind-resistant, opposing being torn from a roof by wind or the like. The shingles each include a pair of vertically spaced-apart lines extending horizontally across the lower ends of butt portions of the shingles, with at least a lower-most line being a line of sealant, and defining between the vertically spaced-apart lines a fastener zone, which fastener zone may have fastening spots therein that, in turn, may define a fastening line. When shingles in accordance with this invention are applied to a roof, the line of adhesive connection between tab portions of shingles in an overlying course are secured to lower ends of butt portions of the shingles of a subjacent course, sufficiently low below the tab portions of shingles, as to preclude any significant engagement by wind or the like that may tend to lift the tab portion off the sealant line.

Abstract: A sheet is provided which can be applied to a planar base and onto which floor boards or tiles can laid, wherein the sheet comprises adhesive strips on its lower and upper sides. The adhesive strips are suitably applied in the longitudinal direction of the sheet. In an preferred aspect, two layers are fixedly connected to one another, a top layer comprising a foamed plastic having a high coefficient of sound insulation and a bottom layer comprising a vapor-tight material and an edge formed by a protruding bottom layer which may be provided on one longitudinal side.

Abstract: This invention relates to commercial roof assemblies applied over a flat roof deck, and, more particularly, to an insulation board composite capable of peel and stick application, in which the insulation board is mechanically attached to a roof deck, a release sheet is removed from the top face of the board (revealing the pressure sensitive adhesive layer), and a non-adhesive waterproofing membrane is then placed onto the adhesive face of the board.

Abstract: An exemplary skid-resistant roofing underlayment provides a pressure-sensitive membrane attached to a carrier support sheet having at least two different plastic films, the carrier sheet being corrugated with ridges in the machine direction to provide skid resistance when the underlayment is installed on a sloped roof. Especially preferred are corrugated, cross-laminated composites having a polypropylene or high density polyethylene layer co-extruded with a linear low density polyethylene layer. An exemplary method for making the roofing underlayment involves corrugating at least two different plastic film layers to provide a carrier support sheet for a waterproofing membrane adhesive layer.

Abstract: The present invention provides a composition ridge or hip covering which creates an appearance similar to that of a wood shake or slate roof. The covering may be easily installed, requires no trimming or folding during installation and may be manufactured with no significant waste of starting material. The covering is accomplished by forming an unfolded sheet of roofing material into a fish-like shape having three distinct portions: a front portion, a body (middle) portion and an end portion. Each portion is tapered and each portion has a specially defined length and taper angle depending upon the shape of the shingle desired. Two thickened multilayers are formed in the body portion by folding the unfolded sheet, one being at the wide end edge of the shingle and the other in the main part of the body portion. The taper angles and lengths of the front portion and end portion are essentially the same.

Abstract: A wallboard package having edge protective tape which connects two wallboards face-to-face, with an adhesive film on the tape inner surface adapted for use in affixing the wallboards to wall studs.
