Rollable roof ventilating device and methods for use thereof

A venting device for a roof, comprising:

• a top panel, made of a weatherproof plastic material, the weatherproof plastic material including two generally planar plies and a convoluted ply between the planar plies, each planar ply joined to the convoluted ply such that a multiplicity of top panel air passages are defined thereby, the top panel air passages extending generally transversely to a longitudinal axis of the top panel, the top panel with first and second lateral edges, each air passage with an exterior opening defined by the weatherproof plastic material at one of the lateral edges, the top panel divided into two sections, the top panel further including an area between the two sections, the area between the two sections defined by a route on an underside of the top panel and in which one of the planar plies and at least a portion of the convoluted ply are removed, the route generally and longitudinally coaxial to a the top panel and defining an interior opening for at least a portion of the top panel air passages;
• a first and a second vent, each vent including a plurality of panels made from a weatherproof plastic material, the weatherproof plastic material including two generally planar plies and a convoluted ply between the planar plies, each planar ply joined to the convoluted ply such that a multiplicity of first and second air passages are defined in the respective first and second vents, the first and second air passages generally parallel to the top panel air passages, each panel in the first and second vents with an internal and an external edge, each first and second air passage with respective internal and external openings defined at the internal and external edges of the panels, the panels of each vent generally underlying each other, an upper panel of each vent in underlying relation to a lower surface of the top panel, the panels of each vent hingedly interconnected, the upper panel of each vent hingedly connected to the top panel, the panels of each vent further connected to the top panel by a fastener, the ventilating device conformable to spiral by being rolled in a direction generally parallel to a longitudinal axis of the ventilating device.

A method of making a device for ventilating a roof, the method comprising the steps of:

• providing a weatherproof material with a first and a second ply joined such that a multiplicity of first air passages is defined thereby;
• defining a first panel in the weatherproof material;
• defining interior openings in at least a portion of the multiplicity of first air passages, the first air passages extending generally transversely to a longitudinal axis of the first panel;
• and
• conforming the first panel into a spiral by rolling the first panel in a direction generally parallel to the first panel longitudinal axis.

A method of making a device for ventilating a roof, comprising the steps of:

• providing a weatherproof material with a first ply and a second ply, the first and second ply joined such that a multiplicity of air passages is defined thereby;
• defining a first panel in the weatherproof material such that the air passages extend generally transversely to a first panel longitudinal axis;
• and
• conforming the first panel into a spiral configuration by rolling the first panel in a direction generally parallel to the first panel longitudinal axis.

A method of installing a venting device on a roof with a slot defined by a sheathing layer, the method comprising the steps of:

• providing a vent assembly, the vent assembly including a first panel made from a weatherproof material, the weatherproof material with a first and a second ply joined such that a multiplicity of air passages is defined thereby, the air passages extending generally transverse to a longitudinal axis of the first panel, the vent assembly conformed into a spiral by rolling the first panel in a direction generally parallel to the first panel longitudinal axis;
• unrolling the vent assembly;
• and
• affixing the vent assembly to the roof.

A process of forming a vent for a roof from a weatherproof material with a fluted layer disposed between first and second generally planar layers such that a multiplicity of generally parallel air passages is formed thereby, the process comprising the steps of:

• providing a sheet of the weatherproof material, the sheet having a longitudinal axis generally transverse the air passages;
• forming a pair of first lateral slits, the longitudinal axis generally disposed between the first lateral slits, each first lateral slit extending through the second planar layer and at least partially through the fluted layer, thereby defining a top panel and two laterally disposed side panels;
• folding each side panel in an underlying relationship to the top panel by automatic folding means;
• securing each folded side panel to the top panel by automatic securing means, thereby forming a vent;
• and
• conforming the vent into a spiral configuration by rolling the vent along the longitudinal axis.
