A hand tool has a plurality of similarly or identically shaped rollers aligned end-to-end along an axle such that the outer surface of each respective roller moves about an axis define by the axle. The hand tool may be a roofing roller tool that enables an impermeable vapor membrane or sheet to be applied to a vertical wall extending upwardly from an outer perimeter of a roof. The tool may be manipulated by an elongated pole handle coupled to a roller head or roller head frame.

Machines and related methods are disclosed for dispensing a rolled fabric over spaced support beams of a roof and for holding the fabric firmly in place over such beams to protect workers from falling through the gaps between the beams. The machines may include one, some, or all of several different components and features to enhance the system's overall operation and effectiveness. One aspect relates to a hub brake used to help prevent unwinding of the fabric roll in the event of a fall. Another aspect relates to a magnetic brake to help keep the machine from sliding across the support beams in the event of a fall. Another aspect relates to a guide assembly that engages a support beam with a one-directional bearing to also help keep the machine from sliding in the event of a fall.

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.

An electric roofing torch comprising a tubular body having an upstream end and a downstream end, a fan unit mounted in the tubular body to drive a flow of air through the tubular body and a heater tube comprising a heater matrix, the heater tube being mounted in the tubular body to heat the flow of air as it passes through the tubular body. The fan unit comprises an electric vaneaxial fan which is mounted upstream of the heater tube. The fan unit is mounted in the tubular body to drive a flow of air through the tubular body at velocity, pressure and volume that is sufficient for roofing operations such as laying roofing membranes, with zero carbon emissions. There is also provided a method of providing a working flow of hot air from the electric roofing torch for such a roofing operation.
