Patent Application
20240183549
This application relates to a sleeved tile roof ridge vent and the method of its use and construction.
Ridge ventilation of tile roofs is known. Roof ridge ventilation systems for tile roofs typically require a ridge board installed using separate brackets and the separate installation of two or more vent pieces to support the cap tile and to provide a base for installing vent bodies or the use of a perforated rolled vent. Further, roof ridge ventilation systems on tile roofs may allow wind-driven rainwater and other rainwater to enter a ventilated space through the roof ventilation system or provide inadequate ventilation due to design and method of application.
Various embodiments of the disclosure provide a ventilation system. The ventilation system includes, in one example, a vent body and a perforated barrier attached to an outer surface of the vent body. The ventilation system further includes a splash guard attached to an outer surface of the perforated barrier, where the splash guard includes a baffle formed at an angle relative to the perforated barrier. The baffle is configured to limit debris from entering through perforations in the perforated barrier.
Various embodiments of the disclosure provide a sleeved tile ridge vent (STRV). The STRV includes, in one example, a vent body including one or more holes and a perforated barrier coupled to the vent body to cover the one or more holes. The STRV further includes a splash guard coupled to the perforated barrier to limit debris from entering through perforations in the perforated barrier.
Additional embodiments and features are set forth in part in the description that follows, and will become apparent to those skilled in the art upon examination of the specification and may be learned by the practice of the disclosed subject matter. A further understanding of the nature and advantages of the present disclosure may be realized by reference to the remaining portions of the specification and the drawings, which form a part of this disclosure. One of skill in the art will understand that each of the various aspects and features of the disclosure may advantageously be used separately in some instances, or in combination with other aspects and features of the disclosure in other instances.
A sleeved tile roof ridge vent (STRV) and methods of its use and construction are disclosed herein. The STRV may be used with either barrel tile or flat tile roofs with a barrel ridge cap tile. The STRV may be used with clay, concrete, metal or synthetic tile roofs. The STRV may provide roof tile support and/or improved net free area (NFA) air flow for ventilation of an attic compared to some conventional vents.
The vent body 110 may double as a structural member to support the weight of a ridge cap tile 116 (see
In some examples, the STRV 100 includes a perforated barrier 124 coupled to the vent body 110, such as attached to an outer surface of the vent body 110. For example, the perforated barrier 124 may be coupled (e.g., attached) to an exterior side of the vent body 110 at a top of the vent body 110 and at the flanges 114. The perforated barrier may prevent, reduce or minimize the ingress of one or more elements (e.g., burning embers) entering into the holes 120 and attic. For example, the perforated barrier 124 may by coupled to the vent body 110 to cover the holes 120. In embodiments, the perforated barrier 124 includes perforations sufficiently small in diameter to stop or limit firebrands and/or burning or smoldering embers from entry into the STRV 100 and attic. The perforated barrier 124 may also allow for adequate net free ventilation area for the egress of stale attic air while also providing resistance to the entry of wind driven rain into the STRV 100 and attic.
In some examples, the STRV further includes one or more splash guards 130 attached to the perforated barrier 124. The splash guards 130 may reduce or minimize debris (e.g., wind driven rain) entering through perforations in the bottom portion of the perforated barrier 124. The profile shape of the perforated barrier 124 combined with attached splash guards 130 may provide an angle which inhibits the upward migration of moisture and subsequent entry into the vent body 110 and attic.
Additionally, the splash guards 130 may have a formed angle that may redirect water away from the perforated barrier 124, providing additional protection from water infiltration. This angle may provide for added turbulence by a baffle 134 such that the laminar air flow caused by incoming wind bearing water is disrupted with turbulence so that moisture does not enter the vent body 110 and the attic. Water that is redirected through such disruption of laminar air flow may drain out through the exterior of the splash guard 130 and onto the flanges 114. The water therefore moves away from the STRV 100, preventing or limiting the amount of water entering into the STRV 100 or attic. The STRV 100 may include additional features such as a second formed angle at the end of the splash guard 130 to further improve both the redirection of water and the disruption of laminar air flow of wind driven rain.
As shown, the baffle 134 may be formed at an angle 140 relative to the perforated barrier 124. For example, the baffle 134 may extend away from a plane of the perforated barrier 124 by the angle 140. Depending on the application, the angle 140 may be an acute angle, such as less than 60 degrees, less than 45 degrees, or less than 30 degrees, although other configurations are contemplated.
The splash guard 130 may further include a sleeved tab 146 extending past the vent body 110. During installation of adjacent STRVs 100 on the ridge of a roof, some locations may include a roof ridge cut extending continuously from gable to gable. In these locations, some sealing is needed for joints that may be otherwise susceptible to water infiltration. Portions of the STRV 100 (e.g., portions of vent body 110 or splash guard 130) may overlap an adjacent STRV 100 such that applying sealant between adjacent vents is not required. For example, the sleeved tab 146 (and/or a sleeved tab of vent body 110) may overlap a portion of an adjacent STRV 100, such as the vent body 110 of an adjacent STRV 100 at a bottom portion of the perforated barrier 124, although other configurations are contemplated. Without such overlap by the sleeved tab 146 (and/or vent body overlap), such installation may require sealant to prevent water infiltration and migration into the STRV 100, ridge slot, and attic. Further, the sleeved tabs (e.g., sleeved tab 146) may allow an installer to install either end of the STRV 100 to be adjacent to another STRV 100 while providing sealing between the two adjacent STRVs 100. The extending sleeved tab(s) allows for installation without application of sealant to the joint between adjacent STRVs 100 and without considering the orientation of the STRV 100 with respect to the adjacent STRV 100. For example, the sleeved tab 146 may be extended on opposite sides and ends of the splash guards 130 attached to the perforated barriers 124, as shown, for example, in
In embodiments, the STRV 100 may include at least one (e.g., two or more) C-shaped bridges 150. In such embodiments, the bridges 150 may be coupled (e.g., mechanically fastened) to the interior base 152 of the vent body 110 to limit or prevent the STRV 100 (e.g., vent body 110) from spreading or distorting, such as when the flanges 114 are bent to adjust the STRV 100 to the prevailing roof slope or pitch. Such spreading or distorting may occur when the flanges 114 are adapted to a lower slope or a steeper slope than a factory pre-set slope for the flanges 114.
In some examples, an optional nonwoven material may be installed between the vent body 110 and the perforated barrier 124 to provide additional protection against infiltration of snow, dust, dirt, and insects from outside of the STRV 100 and into the attic.
The STRV 100 may be partially or completely concealed from the exterior or outside, providing an aesthetic benefit. Unlike existing systems, the STRV 100 may be installed without a ridge board, and no mortar may be required for installing separate injection molded pieces. The ridge cap tile 116 and STRV 100 may generally be secured with mortar, foam, adhesive, or by mechanical fastening. Further, existing solutions may require the installation of individual brackets to separately secure the ridge board above the ridge slot. The STRV 100 described herein may be integrated such that the STRV 100 is installed as one piece without a ridge board or separate brackets and may be installed as a one-piece vent.
As shown in
In embodiments, the STRV 800 may include a stiffening end cap 864 coupled to the vent body 810. For example, the stiffening end cap 864 may be positioned within an interior of the vent body 810. The stiffening end cap 864 may add rigidity to the STRV 800, stiffening the STRV 800 and keeping the STRV 800 straight and preventing twisting. In embodiments, the stiffening end cap 864 may replace, or be used in conjunction with, the bridges 150. In this manner, either the bridges 150 or the stiffening end cap 864 may define an internal brace providing stiffness and/or rigidity to the vent body 110 or 810.
The ventilation systems disclosed herein may provide for concealment of the STRVs 100, 800, allowing for mortar, foam, adhesive, or mechanical fastening of a barrel ridge cap to the vents. The STRVs 100, 800 may be more simple and easier to install than existing solutions. The STRVs 100, 800 may also be used on both curved field tiles and flat field tiles, as well as being readily adaptable to different roof pitches. The STRVs 100, 800 may be utilized to prevent firebrands and flying embers from entering the vent and the attic. The sleeve tabs on the splash guards installed on opposite sides and ends of the STRVs 100, 800 may allow for installation without application of sealant at joints between vents. Adjacent vents may further be installed in any orientation. The angled ends of the splash guards combined with the perforated barriers and vent bodies may provide a multiple barrier system to prevent water infiltration while providing a high net free ventilation area.
