A ballast system for roof membranes includes connected modules filled with loose-fill ballast and adapted to hold a predetermined volume of water for at least a predetermined period of time on the roof to control runoff.

A protected membrane roof system for installation on a roof decking comprising an upper insulation board having an upwardly-facing upper board top surface and an opposite downwardly-facing upper board bottom surface and at least one through-hole communicating therebetween, a ballast material positioned over the upper insulation board, a netting positioned over the ballast material, and at least one fastener assembly having a base seated substantially adjacent the upper board bottom surface, a rod extending substantially vertically from the base of sufficient size so as to extend through the through-hole of the upper insulation board, the ballast material, and the netting, and a cap engaged with the rod above the netting, whereby the wind uplift resistance of the protected membrane roof system is improved and scour of the ballast material is reduced by effectively anchoring the netting to the upper insulation board beneath the ballast material.

Affix a membrane roof cover structure, comprising a polyester foam layer and a new membrane layer, over a roof deck structure such that the polyester foam layer is between the roof deck structure and the new membrane layer.

A membrane roof or temporary building construction facade has a large plastic or textile panel (M) which is supported and secured at its edges (R) by a profile anchorage clamp fitting (H). The membrane (M) terminates at its periphery in an anchorage beading profile (K) which locates within a matching groove (KK) forming part of the clamping profile (5). The clamping profile is located and clamped (2) within a surrounding metal profile (B).

A portable induction heating tool is provided as a membrane roofing tool for use in sealing anchor plates with a heat-activated adhesive to a membrane roofing member. The tool uses two different audible tones so two tools can be used simultaneously on a single roof, while allowing a user to easily distinguish between the operation of both tools. The main housing containing electronics is weather-tight, and requires no forced-cooling devices. The controller automatically performs data logging functions, such as counting the number of anchor plates per job or per day that have been properly placed, counting the number of activation events for a tool's life, tracking the number of faults which occur as the tool is being used, and the controller can identify the type of fault that occurs during operation of the tool. The controller also stores energy setting changes in memory.

Membrane roofs are susceptible to damage in high winds. Wind can lift a membrane roof from a building and cause it to tear or become damaged. The present roof vent prevents liftoff and damage by reducing the air pressure under the membrane during high winds. The present roof vent has two opposed convex domes separated by a gap. Wind blowing across the roof flows between the domes where it accelerates and creates a region of low pressure according to the Venturi effect. The lower dome has an opening at the gap so that the low pressure is applied to the space under the membrane roof. Therefore, when wind blows across the roof, the vent draws air from under the membrane and the membrane is pressed against the roof, preventing liftoff.

A mount for a membrane roof is assembled from first and second metal plates coated on at least one side with heat-weldable material, at least one bolt and two sheets of membrane roofing material. The parts are assembled in a manner that the bolt faces upwards and is effectively sealed in the assembly against any leak around the bolt by a first sheet of roofing material. The mount may be attached to a roof by fasteners around the periphery of the first base plate, and the second sheet of membrane material seals the fasteners and fastener holes.

An apparatus for supporting one or more fixtures on a membrane roof has at least one bracket for interfacing with and securing the one or more fixtures, the at least one bracket coated on one side with a material compatible for heat welding to roofing membrane, a cut piece of roofing membrane having a length and width substantially greater than dimensions of the at least one bracket, wherein the at least one bracket is joined to the cut piece of membrane by heat welding and the piece of roofing membrane is then heat welded to the membrane roof.
