Abstract: An apparatus for placement of seam tape to a roof or roof membrane. The apparatus comprises first and second sides spaced a distance apart, wherein each side includes a material axle opening and a pressure applicator orifice. The apparatus also comprises a removable pressure applicator having a first end and second end positioned in the pressure applicator orifices of the first and second sides. A support element may be operatively attached to the first and second sides, span the distance between the first and second sides, and positioned opposite the pressure applicator to support the apparatus. Additionally, a material axle may be positioned such that its ends are removably positioned in the material axle openings of the first and second sides. A closed front side may connect the first and second side, while an open stern may allow direct access to the pressure applicator, the support element, and the material axle.

Abstract: A roofing membrane comprising a polymer and an infrared reflective compound.

Abstract: An apparatus for seaming roofing membranes to one another, wherein one of the membranes is secured to an underlying support structure by at least one protruding fastener is provided. The apparatus includes a wheeled carriage having an upwardly extending push/pull bar. A power supply propels the wheeled carriage and energizes a heating assembly that generates a heated airflow sufficient to fuse the roofing membranes to one another. A nozzle is coupled to the heating assembly for directing the heated airflow between the two membranes. A variable pressure roller assembly is coupled to the carriage and has a single durometer material carried by an axle that may have different diameter sections. The roller passes over the at least one protruding fastener while still applying a uniform pressure so as to form a substantially continuous width seam except where interrupted by the protruding fastener.
