FIELD OF THE INVENTIONThis invention relates to roof vents and, in particular, this invention relates to vents for tiled roofs.
BACKGROUNDAdequate ventilation is necessary to ensure that the structural materials and roofs is not degraded by the presence of condensed moisture and the presence of wind blown precipitation, insects, particulates, and the like. However, tiled roofs have presented a particular challenge when vents are installed because the contours of tiled roofs are generally undulating with crests and troughs therein. To this end, it has often been necessary to install materials such as foam or the like beneath the vents, such that the foam will fill the contours presented by the tiles. Other materials, such as mortar, blown insulation, or expanding foams have also been used. However, these materials involve extra time and are often inefficient, expensive to install. In addition to being inefficient and adding extra expense, the materials used often degrade due to exposure to sunlight and weathering.
There is then a need for a vent with a feature conforming to the undulating contour of a tiled roof.
SUMMARY OF THE INVENTIONThis invention substantially meets the aforementioned needs of the industry by providing a vent with a feature conforming to the undulating contour of a tiled roof.
This invention provides a venting device for a tiled roof, the venting device comprising a vent member and a sealing member, the sealing member including a malleable material, capable of being configured and sealed to the undulations of the tiled roof.
It is a feature of the instant vent that the sealing member folds between a position substantially beneath the vent member and a position wherein a portion of the sealing member is substantially outboard the vent member. It is an advantage of the foregoing feature that the sealing member, when folded inwardly, occupies a minimum volume for efficient and economic storage and transport.
It is yet another feature of the instant vent that a portion of the sealing member may be configured between a folded and an unfolded configuration. It is an advantage of the foregoing feature that the sealing member may be folded for transportation and storage, then unfolded to be configured to, and seal, an undulating roof.
It is yet another feature of the instant vent that the sealing member has an undulating, convoluted configuration. It is an advantage of the foregoing feature that the sealing member can accommodate a convoluted roof configuration when portions of the convoluted sealing member are unfolded, or straightened, when being pressed against, or conformed to, the roof.
It is yet another feature of the instant vent that the sealing member is configurable to individual roof contours. It is an advantage of the foregoing feature that the instant vent may be configured to roof contours, which are not uniform. It is another advantage of the foregoing feature that the instant vent may be installed on roofs having non-identical opposing slopes, e.g., due to errors during installation.
These and other objects, features, and advantages of this invention will become apparent from the description which follows, when considered in view of the accompanying drawings.

In case of conflict, the present specification, including definitions, will control. In addition, the materials, dimensions, methods, and examples are illustrative only and not intended to be limiting.
Any references to such relative terms as front and back, right and left, top and bottom, upper and lower, horizontal and vertical, or the like, are intended for convenience of description and are not intended to limit the present invention or its components to any one positional or spatial orientation.
Each of the additional features and methods disclosed herein may be utilized separately or in conjunction with other features and methods to provide improved devices of this invention and methods for making and using the same. The following description is merely intended to teach a person of skill in the art further details for practicing aspects of the present teachings and is not intended to limit the scope of the invention. Therefore, specific combinations of features and methods disclosed in the following detailed description may not be necessary to practice the invention in the broadest sense, and are instead taught merely to particularly describe representative embodiments of the invention. Thus, a person of ordinary skill in the art will readily appreciate that individual components shown on various embodiments of the present invention are interchangeable to some extent and may be added or interchanged on other embodiments without departing from the spirit and scope of this invention.
Referring to the figures, a sealable vent for a tile roof ridge of this invention is indicated generally at 100 and includes a vent member 102 and a sealing member 104 extending from one of or each lateral edge of the vent member 102.
One embodiment of the vent member 102 is a top panel 110 attached to respective first and second vents 112 and 114 in a generally overlaying manner. The vents 112, 114, in turn, may be made from a plurality of vent panels 116 disposed in a parallel, generally contacting relation. A filtering fabric 118 may also be present. If present, the filtering fabric 118 may be attached to the vent member 102 so that an airflow egressing from a building through the vent member 102 must flow through the filtering fabric 118 before egressing the vent member 102. In the embodiment depicted, lateral ends of the filtering fabric 118 are attached to lower surfaces of the bottom-most vent panels 116. Air exchange is effected through airflow passages 120 formed from the corrugated material of the top panel 110, vent panels 116 and from a route 122 formed generally axially and longitudinally in the top panel 110. This and other exemplary and suitable vent members are disclosed and described in U.S. Pat. No. 6,623,354, hereby incorporated by reference.
The sealing member 104, in the embodiment shown, is attached to the lower vent panel 116 of each first and second vent 112, 114 by an adhesive strip 130, e.g., including butyl adhesive. The sealing member 104 may be made from a malleable metal, such as aluminum or the like with a thickness providing the requisite malleability, resilience, and resistance to weathering. However, materials such as synthetic resins and fabrics having the requisite stiffness, malleability, stretch characteristics (e.g., “memory,” rubberized), and resistance to weathering and sunlight may be suitable for other embodiments. In the embodiment depicted, the sealing member 104 includes a folded section 132 and a sealing section 134 and is fashioned from a pleated or a corrugated material having wave-like convolutions 136 which may be characterized as having a trough 138, a crest 140, and a period or wavelength 144. Layers 145 of the folded section 132 are defined by creases 146, a crease 146 also separating the folded section 132 from the sealing section 134. Each crease 146 is formed by crushing the corrugated material axially, so as to flatten the troughs 138 and crests 140 along a generally longitudinal line.
An adhesive strip 148 is present on the lower surface of the lateral edge of each sealing section 134 and a strip of a release material 150 overlays the adhesive strip 148. The adhesive of the adhesive strip 148 may be made from a material such as butyl adhesive and the release material may comprise materials such as paper or a synthetic resin, optionally with a release material such as silicone.
The sealing member 104, after being creased and folded as described above, is attached to lateral edges of the first and second vent panels 112, 114 by means of applying the adhesive strip 130, e.g. about 2.54 cm wide and 0.1778 mm thick. The adhesive strip 148 may be applied to a lower surface of the sealing section 134 in an axial band, e.g., about 2.22 cm wide and about 4.76 mm thick.
In use, the sealing members 104 of the roof ventilator 100 are folded outwardly as depicted in
Referring to
Fasteners, such as staples 228, may then be placed into the top panel 110 and extended through each of the vent panels 210, 212 and 214 to secure the vent panels in place with respect to the top panel 110.

Referring to
The upper surface 264 of the mat 256 may be reinforced adjacent nail lines 280 and 282. Each nail line 280 and 282 extends in a longitudinal direction on one of lateral flap 262 and 264, respectively, and maybe located at a spaced distance from the centerline hinge 258 and edge flanges 276 and 278. The mat 256 may be reinforced with one or more strips of nail line reinforcement material 284, which may be bonded to the upper surface 264 of the mat 256. The nail line reinforcement material may be a sheet-like fabric material, such as non-woven nylon polyester, an elastomeric material, or other synthetic resin.
