Abstract
Disclosed is a vent system for use with a shingle cap and with a roof structure having a ridge slot. The vent system comprises: a pair of elongate mats disposed, in use, on opposite sides of the ridge slot; and an elongate web extending between the mats and, in use, covering the ridge slot. The mats and the web are covered in use by the shingle cap. The mats have an open texture sufficient to allow venting of the roof to occur therethrough.
Description
RIDGE VENT
FIELD OF THE INVENTION
This invention is related to the general field of roof ventilation systems. It is particularly related to roof ridge ventilators.
BACKGROUND OF THE INVENTION
It has been a long known practice to ventilate attics under gable roofs by running a vent along the roof ridge.
Some structures place a type of porous material over the slot, which is then covered by the same roofing material as the rest of the roof, such as shingles or tiles.
For example, United States Patent Islo. 5,167,579 teaches a fibrous mat as the porous material, with shingles nailed over the matrix leaving the side edges open to vent hot air.
This mat is a non-woven synthetic fiber mesh of a type that has been used in other applications for scrubbers and polishers. To produce this known mat, synthetic fibers (usually nylon or polyester) are opened and blended, then randomly aligned into a web by airflow. The web is then treated with binding agents of water based phenolics and latexes.
The treated web is then oven-cured to bind the fibers into a relatively rigid mat having a significant porous area between the random fibers.
Mat of this prior art type are typically sold in rolls having widths that corresponds to typical shingle caps. Thus, if a roofer uses shingle caps of varying widths, that roofer typically maintains multiple rolls of mat material, in varying corresponding widths.
SUMMARY OF THE INVENTION
The present invention provides a vent system for use with a shingle cap and with a roof structure having a ridge slot and comprises a pair of elongate mats and an elongate felt defining a web. Each mat can be about 4.5 inches in width. The felt can define a backer for each mat and can be connected to the mats such that, when the mats are fully separated from one another, the mats are about inches apart from one another and joined by the felt. In use, the system is arranged with the mats disposed on opposite sides of the ridge slot, the felt covering the ridge slot and the shingle cap covering the vent system.
By varying the position of the mats relative to the ridge slot, and thereby varying the slack in the felt, the system can be used with shingle caps of varying widths.
The mats have an open texture sufficient to allow venting of the roof to occur therethrough. The mats can sufficiently resistant to compression that the installer can easily feel when the shingle is pressed firmly against the mat and sink the nail only until the nail head is against the shingle, leaving the cap raised about 5/8 inch above the underlying roof shingles. The mats and the felt can be non-wicking and can define an effective barrier against wind-driven rain and against insects.

2 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The present invention represents an improvement over the roof ridge vent described in United States Patent No. 5,167,579 ["the '579 Patent"]. For ease of reference the Prior Art ridge vent described in the '579 Patent is shown in FIGs. 1 to 3. The improved ridge vent of the present invention is constructed and used in a manner generally similar to that vent described in the '579 Patent. For economy in language, only differences in the structure and differences in the use between the vent system of the present invention and the vent of the '579 Patent are hereinafter described.
In terms of improvement, it will be apparent that prior art ridge vents of the general type described in the '579 Patent are defined by a single width of fibrous, breathable mat material that is arranged to straddle a roof ridge slot.
Mats of this prior art type are typically sold in rolls having widths that corresponds to typical shingle caps. Thus, if a roofer uses shingle caps of varying widths, that roofer typically maintains multiple rolls of mat material, in varying corresponding widths.
The vent system 20 of the present invention is for use with a tile or shingle cap 22 and with a roof structure having a ridge slot 24 and comprises a pair elongate mats 26 and an elongate web 28 defined by a felt. Each mat 26 can be about 4.5 inches in width. The felt 28 can define a backer for each mat 26 and be connected to the mats 26 such that, when the mats are fully separated from one another, as shown in FIG. 4, the mats 26 are about 3 inches apart from on another and joined by felt 28.
In use, as shown in FIG. 4, the system 20 is arranged with the mats 26 disposed on the shingle roof 30 on opposite sides of the ridge slot 24, the felt 28 covering the ridge slot 24 and the shingle cap 22 covering the venting system 20 and secured to the roof by nails 32. Although not shown, it will be understood that, by varying the position of the mats

In use, as shown in FIG. 4, the system 20 is arranged with the mats 26 disposed on the shingle roof 30 on opposite sides of the ridge slot 24, the felt 28 covering the ridge slot 24 and the shingle cap 22 covering the venting system 20 and secured to the roof by nails 32. Although not shown, it will be understood that, by varying the position of the mats
3 relative to the ridge slot, and thereby varying the slack in the felt, the system can be used with shingle caps of widths narrower than that illustrated in FIG. 4 with no associated protrusion of the mats.
The improved vent system can be sold in rolls in a conventional manner.
Whereas but a single exemplary embodiment is herein shown and described, it will be evident that changes can be made. Accordingly, the invention should be understood as limited only by the accompanying claims, purposively construed.
