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.

A vent assisted system for reroofing a built up roof surface or a single ply membrane roof covering including an augmented design incorporating mechanical fasteners and an adhesive for attaching strips of single ply membrane or fleece backed single ply membrane in the turbulent vortex areas along the perimeter of a deck. Coupled with roof vents for equalizing the pressure under loose laid sheets of single ply membrane or fleece backed single ply membrane in the field-of-roof area bordering the turbulent wind vortex areas to reduce membrane stress and resist wind uplift pressures during high wind events.

The present subject matter provides apparatus for connecting a roof assembly to a membrane using at least one backer rod connected to the membrane, including: counterflashing disposed about the perimeter of the roof assembly, the counterflashing including a plurality of grips configured to receive and engage the at least one backer rod in contact with the membrane, so as to hold the membrane securely in position and maintain a weather seal at a desired flashing height of the membrane. In various examples, the roof assembly includes a roof hatch, window, or other fenestration unit. In various examples, the present subject matter provides a hatch attached to a wall for sealing an opening. In various examples, the present subject matter provides a method for operating a roof assembly for connection to a roof membrane.

A roofing membrane may include a main body, a first material, and a second material. The first material may be bonded to the main body and positioned toward a first edge thereof. The second material may be bonded to the main body and positioned toward a second edge thereof. The second edge may be positioned opposite the first edge such that the first and second materials are positioned toward opposite edges of the main body. At least one of the first material or the second material may include a first reactive material of a chemically reactive two-part cure system that is configured to chemically react upon contact of the first reactive material with a second reactive material of the chemically reactive two-part cure system.

A device for heating and connecting sheets (11, 12, 111, 121) of bituminous or synthetic membranes (100), comprising at least one sheet (11, 12, 111, 121) of a bituminous or synthetic membrane (100) which is applied to at least one base layer (141), said membrane (100) being formed with a single compound or having at least one bottom layer including a compound or a bituminous mixture and at least one upper layer including a polymeric material and an electrically conductive material, which is heated; in particular, a body (13, 23) having a mainly longitudinal (A) development and placed on a first edge (11a, 21a) of a first sheet (11, 21, 111, 121) of the membrane (100) in order to connect said first edge to a second edge (12a, 22a) of a second sheet (12, 22, 111, 121) of the membrane (100) is provided with an upper face (13a, 23a).

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.

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.

A method of pulling a sheet of flexible material includes forming a row of a plurality of lengthwise slits in a sheet of material; providing at least one pull device; and providing at least one cable winch. A tubular pull rod is inserted through the plurality of slits. A pull device preferably includes a first pull strap, a second pull strap, a spreader bar and a strap ring. First and second pull devices are positioned near opposing sides of the sheet of material. First and second winches are secured to the floor on one sidewall of the building. The sheet of material is laid on the floor at an opposing sidewall of the building. Cables from the first and second winches are pulled over struts in the building and secured to the first and second pull devices. The sheet of flexible material is pulled to the one sidewall.

A seamless sheet installation system preferably includes a seamless sheet and a plurality of sheet retention devices. The seamless sheet is retained on a tube. A pair of rotating retention devices may be inserted into ends of the roll. Each rolling retention device includes a tube plug and a rotating handle. An end of the seamless sheet is secured to the top eave flange. The seamless sheet is held against a bottom of the eave purlin web with one of the plurality of sheet retention devices. The sheet retention device may have any suitable design. The seamless sheet is rolled out to successive purlins, wrapped over the top flange and anchored to a bottom of the vertical web with one of the plurality of sheet retention devices. The seamless sheet wrapping process is terminated at an opposing eave purlin or a ridge purlin. Insulation is then inserted between adjacent purlins.
