Description
- This application claims the benefit of U.S. Design Application No. 29/327,214, filed Oct. 31, 2008, and Ser. No. 29/332,162, filed Feb. 10, 2009, the disclosures of which are incorporated herein by reference.
- Buildings, such as for example residential buildings, may be covered by a sloped roof. The interior portion of the building located directly below the sloped roof can form a space called an attic. If unventilated, condensation can form on the interior surfaces within the attic. The condensation can cause damage to various building components within the attic, including, but not limited to the insulation, as well as potentially causing damage to the building structure of the attic. Accordingly, it is known to ventilate attics thereby helping to prevent the formation of condensation. One example of a method of ventilating an attic includes the positioning of ridge vents at the roof ridge, which is the intersection of the uppermost sloping roof planes. The ridge vents can cooperate with eave vents, positioned in the eaves, to allow a flow of air to enter the eave vents, travel through a space between adjoining roof rafters to the attic, travel through the attic and exit through the ridge vents.
- Ridge vents can be positioned over an elongated opening formed between the uppermost sloping roof planes. The opening can allow hot air within the attic to escape the attic. Ridge vents can be provided in discrete sections that can be placed end-to-end over the opening. The discrete sections of the ridge vents can be flexed to conform to the shape of the sloping roof planes and attached to the roof planes via roof nails. It would be advantageous if ridge vents were easier to install.
- In accordance with embodiments of this invention, there are provided ridge vents configured to cover an open ridge of a roof and allow a flow of air to exit from the open ridge through the ridge vents. The ridge vents include a center portion having a length and a plurality of grooves. Left and right portions are connected to the center portion. The center portion is configured to flex along it's length, thereby forming a ridge vent angle between the left and right portions. The formed ridge vent angle is configured to correspond with a slope between roof decks defining the open ridge.
- In accordance with other embodiments, there are also provided ridge vents configured to cover an open ridge of a roof and allow a flow of air to exit from the open ridge through the ridge vents. The ridge vents include a center portion having opposing ends. Each of the opposing ends has a plurality of projections, each having a plurality of legs that have a cross-sectional shape in the form of a “V”. The plurality of legs form sealing structures. Left and right portions are connected to the center portion. The plurality of legs of the plurality of projections are configured to nest against each other as the center portion of the ridge vent is flexed, thereby forming sealing structures at the end of the center portion of the ridge vent.
- In accordance with other embodiments, there are also provided methods for installing ridge vents over an open ridge of a roof and allow a flow of air to exit from the open ridge through the ridge vents. The methods include the steps of providing a ridge vent, the ridge vent having a center portion and a left and right portion connected to the center portion, the center portion having a length and a plurality of grooves, the grooves having a shallow dome-shaped cross-sectional shape, wherein the center portion is configured to flex along it's length, thereby forming a ridge vent angle between the left and right portions, flexing a first ridge vent to form a ridge vent angle, wherein the ridge vent angle is configured to correspond with a slope between roof decks defining the open ridge, positioning the first flexed ridge vent over the open ridge of the roof, fastening the first flexed ridge vent to the roof decks, flexing subsequent ridge vents, connecting the subsequently flexed ridge vents to the previously installed ridge vents, fastening the subsequently flexed ridge vents to the roof decks and covering the installed ridge vents with ridge shingles.
