Embodiments of the invention provide composite roofing strips that may be attached to a roofing membrane for aesthetic and/or functional purposes and method of attaching the same. According to one embodiment, a composite roofing strip may include a longitudinally extending body having a base and a lateral member extending from the base, and may also include an insert extending partially or fully along the body and coupled therewith. The insert may be formable so as to allow the composite roofing strip to be adjusted to have a desired profile and to maintain the desired profile of the composite roofing strip post adjustment.

A roofing system, comprising an underlayment layer above a roof deck; at least one strap spaced horizontally up the slope of a roof deck and above the underlayment layer; at least two fasteners attached to the at least one strap and into the roof deck; at least one bead of adhesive applied above the at least one strap; and at least two metal roofing panels placed on the at least one bead of adhesive applied to the at least one strap.

Fastener systems for roofing systems are disclosed for fastening a fabric, mesh, or base sheet to a roof deck prior to application of a liquid applied roof coating. The fastening assemblies may be attached to an uncleaned or unprimed roof deck and a fabric is laid atop the fasteners. The fasteners secure the fabric using mechanical binding or chemical bonding without penetrating or dimpling the fabric.

A mounting assembly for a membrane roof has a metal base plate coated on both sides with material compatible to heat weld, a plurality of openings spaced around an outer periphery, one further hole within the pattern having a bolt passing upward through the hole, and a first sheet of roofing membrane material having length and width dimensions smaller than those of the metal base plate, heat welded over the bolt head.

A roofing system, comprising an underlayment layer above a roof deck; at least one strap spaced horizontally up the slope of a roof deck and above the underlayment layer; at least two fasteners attached to the at least one strap and into the roof deck; at least one bead of adhesive applied above the at least one strap; and at least two metal roofing panels placed on the at least one bead of adhesive applied to the at least one strap.

An adhesive composition for use on a fleece-backed roofing substrate includes two components that are mixed prior to application on the fleece backed roofing substrate. The first component includes renewable polyol, catalyst, fumed silica, and surfactant. The renewable polyols are selected from any non-petroleum based polyol that is derived from a renewable source. The second component includes isocyanates, including renewable and non-renewable isocyanates.

A roofing system, comprising: at least one strap spaced on centers horizontally up the slope of a roof deck; at least one bead of adhesive applied to the at least one strap; at least two metal roofing panels placed on the at least one bead of adhesive applied to the at least one strap; and at least two fasteners attached to the at least two metal roofing panels and into the roof deck at a top and perimeter of the at least two metal roofing panels.

Provided are roofing membranes comprising pressure-sensitive adhesives particularly adapted for use at cold temperature, and methods for using same. In one aspect, the disclosure provides a roofing membrane comprising: a bituminous sheet having a lower bituminous surface and an upper bituminous surface; and a non-bituminous cold-temperature pressure-sensitive adhesive disposed on the lower bituminous surface, the upper bituminous surface, or both, wherein the cold-temperature pressure-sensitive adhesive has an average adhesion of at least 10 lbs/ft (146 N/m) at 2 C. as measured by a two hour T-peel test.

A roofing system includes a construction board positioned over a roof deck and a plurality of fastening plates positioned on a top surface of the construction board. At least one connector extends between two of the plurality of fastening plates and is positioned on the top surface of the construction board. The construction boards may be insulation or cover boards, and in certain embodiments may be polyisocyanurate boards. Fasteners are driven through the fastening plates and the construction boards and into an underlying roof deck to secure the construction boards in place.

A method comprises selecting a mounting bracket having opposite horizontal, parallel wings, and a raised portion between the wings, applying a coating of an uncured first sealant material to a first area of a roof surface above decking of the roof, the first area having an outer perimeter greater than overall area of the bracket, urging undersurfaces of wings of the bracket into the uncured sealant material, securing the mounting bracket to the roof by screws applied into the roof decking through holes provided in the wings of the bracket, and applying a second sealant material over heads of the screws on upper surfaces of the wings of the bracket.
