Abstract: A roof portion including solar roof panels and field vents is disclosed. The roof portion includes a sloped roof deck and a cover layer spaced above the roof deck to form a gap between the roof deck and the cover layer. The cover layer includes a layer of cover elements, and a field of one or more solar panels generally within the layer of cover elements. The cover layer also includes a first plurality of field vents positioned within the cover layer substantially immediately below the solar panel field. The cover layer further includes a second plurality of field vents positioned within the cover layer substantially immediately above the solar panel field. The field vents permit airflow between the gap and the atmosphere above the roof.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A roof of a building is provided. The roof comprises a roof frame, a layer of curved roof cover elements (e.g., tiles) above the roof frame, and a solar panel secured to one or more of the roof cover elements. The solar panel substantially conforms to one or more curved surfaces of the one or more roof cover elements. Another aspect provides a roof comprising a roof frame, a layer of curved roof cover elements (e.g., tiles) above the roof frame, a vent member within the roof cover element layer, and a solar panel. The vent member has a curved surface and is sized and shaped to mimic the appearance of one or more of the roof cover elements. The vent member also has an opening allowing a ventilation airflow from the building interior toward an airspace above the vent member and the roof cover element layer. The solar panel is secured to and substantially conforms to the curved surface of the vent member.
