A dual strip protective edge film system for a roofing membrane having a first protective edge film strip covering a top edge portion of the roofing membrane and a second protective edge film strip covering a top portion of the roofing membrane, wherein the second protective edge film strip is positioned in parallel next to the first protective edge film strip, and wherein both of the edge strips have a combined width approximately equal to the width of the overlap between two overlapping roofing membranes that are adhesively secured or thermally welded together.

An apparatus and related methods for constructing articles with cured pressure-sensitive adhesives comprising (i) a coater that applies a curable adhesive to a membrane; (ii) a cross-linking apparatus adapted to receive said membrane with said curable adhesive, said cross-linking apparatus comprising a light source positioned a first predetermined height above an aperture plate having an aperture therethrough, wherein said aperture plate is positioned a second predetermined height, said first predetermined height and said second predetermined height selected to define an exposure area of light emitted from said light source on to said curable adhesive to form a composite product; and (iii) a roll adapted to receive said composite product, said roll adapted to control a speed at which said membrane with said curable adhesive is exposed to light from said light source.

A roofing system includes a roofing membrane. The roofing membrane has a surface energy of 40 mN/m or less. The roofing system includes a roofing substrate. The roofing system includes an adhesive disposed between the roofing membrane and the roofing substrate. The adhesive includes a styrenic block copolymer. The styrenic block copolymer is present in an amount of 0.5 wt. % to 30 wt. % based on a total weight of the adhesive. The adhesive includes asphalt. The asphalt is present in an amount of 70 wt. % to 99.5 wt. % based on the total weight of the adhesive. A ratio of the styrenic block copolymer to the asphalt in the adhesive is 1:11 to 1:3.

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 building membrane having a generally planar core having a top surface and a bottom surface, a polymeric back coat positioned below the bottom surface of the core; a polymeric face coat positioned above the top surface of the core; an adhesive base on at least a portion of the back coat adapted for adhering the building membrane to a building substrate.

A mounting device for covering a roof penetration in a roof includes a base having a hub, an outer perimeter structure, an open top, an open bottom, and ribs extending from the hub outward to the outer perimeter structure. An internal reservoir in communication with the open top and the open bottom. At least one of the ribs is formed with a bore for receiving a fastener for fastening the mounting device at the roof penetration.

A unique method and apparatus for metal valley installation that waterproofs shingled roof applications in valley (e.g., such as “V” or “W” metal valley angled roof) applications. Applicant's invention provides a membrane situated between the metal valley and the shingles with a portion of the membrane being situated and secured to the roof deck between the ice and water shield and the shingles. The membrane creates a dead zone that collects or prevents ice and water from backing up from the roof valley over the metal valley, over the edge of the metal valley, and in between the ice and water shield and the shingles.

Fastener systems and methods of attaching one or more layers of materials to a roof deck of a roof structure for forming a roof are disclosed. In embodiments, the fastener systems can include a plate having first and second surfaces with an aperture extending between the first surface of the plate and the second surface of the plate and configured to receive a fastener therein. A cover portion is provided to substantially enclose the first end of the aperture so as to cover a head of the fastener received within the aperture and protect the fastener from impacts due to objects striking the roof structure.

A system for adhering a roof board onto a corrugated roof by positioning an adhesive strip dispensing machine over a plurality of parallel top flutes of a corrugated roof and then simultaneously dispensing a plurality of adhesive strips on top of each of the plurality of parallel top flutes of the corrugated roof. The dispensing machine has a plurality of wheels or rollers mounted to a frame and a plurality of adhesive roll dispensers, and the adhesive is dispensed onto the top of top flutes by moving the dispensing machine in a direction parallel to the top flutes.

A moisture curable, non-bitumen based and non-asphaltic based adhesive includes an extender, a compatibilizer, and a polymer, wherein the polymer includes reactive silyl groups.
