20080287053 | ROOF RIDGE VENT WITH IMPROVED TROUGH - A ridge vent for covering an open ridge of a roof comprises an elongated panel having two opposed lateral edges; a pair of elongated sidewalls, each extending downward from one of the lateral edges; a pair of elongated floor portions, each extending outward from one of the sidewalls; a pair of elongated baffles, each extending upward from one of the floor portions, each baffle combining with one of the sidewalls and one of the floor portions to form an elongated trough along one side of the panel; and a filtering structure over each trough between the sidewall and the baffle to prevent particles and debris from collecting in the trough while allowing free flow of air. | 11-20-2008 |
20080287054 | ROOF RIDGE VENT WITH SEALANT - A ridge vent for covering an open ridge of a roof comprises an elongated panel with two opposed lateral edges; a pair of elongated sidewalls extending downward from one of the lateral edges; a pair of elongated floor portions each extending outward from one of the sidewalls, each floor portion having an underside; and a sealant on the underside of at least a part of each floor portion to improve the seal between the floor portions and the roof. | 11-20-2008 |
20090203308 | AUTOMATIC ROOF VENTILATION SYSTEM - A roof ventilation system operable based on environmental parameters is disclosed. The system includes a vent, a fan, a solar panel, a battery and a controller. The vent is positioned within a field of a roof, and includes a first opening configured to allow airflow between regions above and below the roof. The fan is positioned to generate an air flow through the vent. The solar panel is positioned on the roof in a location such that the solar panel receives solar radiation. The battery is electrically connected to the solar panel. The controller is in communication with the fan, and is configured to drive the fan based on at least one environmental parameter. | 08-13-2009 |
20090286463 | EMBER-RESISTANT AND FLAME-RESISTANT ROOF VENTILATION SYSTEM - This application relates to ventilation systems, more particularly to roof ventilation systems that help to protect buildings against fires. The roof vent has an ember impedance structure that impedes the entry of flames and embers or other floating burning materials while still permitting sufficient air flow to adequately ventilate a building. Several configurations of vents employing baffle members and fire-resistant mesh material are described, which can substantially prevent the ingress of floating embers and flames. | 11-19-2009 |
20100330898 | ROOF VENTILATION SYSTEM - This application relates to ventilation systems, more particularly to a roof vent with one or more fan assemblies and/or an associated solar panel. The roof vent has an upper member including at least one opening that permits air flow between regions above and below the upper member. The vent further includes a lower member in fluid communication with the region below the upper member. The lower member includes a second opening permitting air flow between a region below the roof deck and the region below the upper member. The lower member further includes a fan configured to generate air flow through the second opening, wherein the fan resides in a fan housing positioned below the second opening. | 12-30-2010 |
20120073216 | ABOVE SHEATHING VENTILATION SYSTEM - A roof structure and a vented eave riser are described. A vented eave riser can include a barrier wall with one or more air flow openings, and an ember impedance structure positioned proximate to the barrier wall. A roof structure may comprise a roof deck and a layer of roof cover elements spaced above the roof deck to form an air layer between the roof deck and the roof cover elements. The roof structure may also comprise one or more vent members each replacing and mimicking an appearance of one or more roof cover elements of the layer of roof cover elements, and/or at least one vented eave riser positioned at an eave between the roof deck and the layer of roof cover elements. The vent members and/or the vented eave riser may further include an ember impedance structure, such as a fire-resistant mesh material or a baffle structure. | 03-29-2012 |
20130019548 | VENTILATION SYSTEM FOR ROOF - A roof vent and a roof structure are described. A roof vent can include a baffle with a cross-section where a first portion extends upward from a bottom plate and a second portion extends from the first portion to define a space between the bottom plate and the second portion. A roof structure may or may not have a roof deck, and comprises a plurality of roof cover elements with a radiant barrier layer underneath the top surfaces of at least some of the roof cover elements. In another embodiment, a roof structure may comprise more sheathing layer vent members than roof cover layer vent members. In yet another embodiment, a roof structure may comprise a layer of roof tiles with at least one vent member, the vent member comprising lateral end portions of a base member with a non-planar profile to engage a similar profile of an adjacent roof cover element. | 01-24-2013 |
20140099878 | AUTOMATIC ROOF VENTILATION SYSTEM - A roof ventilation system operable based on environmental parameters is disclosed. The system includes a vent, a fan, a solar panel, a battery and a controller. The vent is positioned within a field of a roof, and includes a first opening configured to allow airflow between regions above and below the roof. The fan is positioned to generate an air flow through the vent. The solar panel is positioned on the roof in a location such that the solar panel receives solar radiation. The battery is electrically connected to the solar panel. The controller is in communication with the fan, and is configured to drive the fan based on at least one environmental parameter. | 04-10-2014 |
20140318038 | ABOVE SHEATHING VENTILATION SYSTEM - A roof structure and a vented eave riser are described. A vented eave riser can include a barrier wall with one or more air flow openings, and an ember impedance structure positioned proximate to the barrier wall. A roof structure may comprise a roof deck and a layer of roof cover elements spaced above the roof deck to form an air layer between the roof deck and the roof cover elements. The roof structure may also comprise one or more vent members each replacing and mimicking an appearance of one or more roof cover elements of the layer of roof cover elements, and/or at least one vented eave riser positioned at an eave between the roof deck and the layer of roof cover elements.
