1. Field of the Invention
The present invention relates generally to roof ventilation and more specifically to a customizable ridge ventilator, which may be modified to accommodate different roof pitches and air flow requirements.
2. Discussion of the Prior Art
Proper ventilation of a roof prevents premature failure of roofing materials (such as shingles) due to excessive heat; moisture due to condensation, thus preventing a major source of mold and mildew; and ice damming in cold climates, which also leads to premature failure of roofing materials. Some of the factors that dictate ventilation requirements include roof size, attic space area, length of roof ridge, length of roof eaves, pitch of roof, the amount of insulation below the roof, exposure to sun, climate, humidity and temperature extremes.
There are numerous ridge ventilators in the art. U.S. Pat. No. 5,427,571 to Sells discloses a ventilated cap system for the ridge of a roof. The Sells patent includes an expandable utility cap to seal over a variably expanding metal roof. In one form, a top cap may snap lock over the utility cap for slidable attachment thereto when exposed to deforming forces such as ice or snow. The top cap prevents deformation of the underlying utility cap. However, the Sells ridge ventilator is not easily customizable.
Accordingly, there is a clearly felt need in the art for a customizable ridge ventilator, which may be easily modified to accommodate different ventilation factors.
The present invention provides a customizable ridge ventilator, which may be modified to accommodate different roof pitches and air flow requirements. The customizable ridge ventilator includes a first support bracket, a second support bracket, a perforated support and a ridge cover. The first support bracket has a substantially Z-shaped cross section. The second support bracket includes at least one base member and a support member. The first support bracket is attached to a first surface, adjacent one side of a ventilation opening and the base member of the second support bracket is placed on a second surface, adjacent the other side of the ventilation opening. The base member is structured to receive the support member. A roof membrane is placed over the base and support members.
The perforated support is a formed plate with a plurality of perforated openings. The perforated support preferably includes a cross section with a lengthwise section, a substantially vertical flange and a snap flange. The substantially vertical flange extends upward from one end of the lengthwise section and snap flange extends downward from the other end of the lengthwise section. The substantially vertical flange is secured to the support member and the roof membrane, and substantially a middle of the lengthwise section is secured to first support bracket.
The ridge cover includes a top portion, a sloped leg, an attachment leg, a snap clip and a drip extension. The sloped leg extends from a first side of the top portion and the attachment leg extends from the second side of the top portion. The sloped leg is terminated with the snap clip. The attachment leg is terminated with the drip extension. The attachment leg is slid over the roof membrane and the snap clip is slid over the snap flange of the perforated support. A cover splice includes a cross section that has the same shape as the ridge cover. The cover splice is sized to be received by an inner perimeter of the ridge cover. Two adjacent ridge covers are connected to each other with the cover splice.
A second embodiment of the customizable ridge ventilator includes a support bracket, a perforated support and a ridge cover. The support bracket has a substantially Z-shaped cross section. The first support bracket is attached to a first surface, adjacent one side of a ventilation opening. The perforated support is a formed plate with a plurality of perforated openings. The perforated support preferably includes a cross section with a top perforated portion, a dished perforated portion, a substantially vertical perforated portion, a first snap flange and a second snap flange. The dished perforated portion extends from one side of the top perforated portion and the substantially vertical perforated portion extends downward from the other side of the top perforated portion. The dished perforated portion is terminated with the first snap flange and the substantially vertical perforated portion is terminated with the second snap flange.
The ridge cover includes a top portion, a sloped portion, a substantially vertical portion, a first snap clip and a second snap clip. The sloped portion extends from one side of the top portion and the substantially vertical portion extends from the other side of the top portion. The sloped portion is terminated with the first snap clip and the substantially vertical portion is terminated with the second snap clip. The first snap clip is slid over the first snap flange and the second snap clip is slid over the second snap flange. A cover splice includes a cross section that has the same shape as the ridge cover. The cover splice is sized to be received by an inner perimeter of the ridge cover. Two adjacent ridge covers are connected to each other with the cover splice.
A third embodiment of the customizable ridge ventilator includes a support bracket, a perforated support and a ridge cover. The support bracket has a substantially Z-shaped cross section. The support bracket is attached to a surface, adjacent one side of a ventilation opening. The perforated support is a formed plate with a plurality of perforated openings. The perforated support preferably includes a cross section with a dished portion, a snap flange and a perforated attachment flange. One end of the dished portion is terminated with the snap flange and the other end of dished portion is terminated with the perforated attachment flange.
The ridge cover preferably includes a cross section with a sloped top portion, a snap clip and an attachment flange. One end of the top portion is terminated with the snap clip and the other end of sloped top portion is terminated with the attachment flange. The snap clip is slid over the snap flange and the attachment flange is laid over the perforated attachment flange. A cover splice includes a cross section that has substantially the same shape as the ridge cover. The cover splice is sized to be received by an inner perimeter of the ridge cover. Two adjacent ridge covers are connected to each other with the cover splice.
Accordingly, it is an object of the present invention to provide a customizable ridge ventilator, which may be easily modified to accommodate different ventilation factors.
These and additional objects, advantages, features and benefits of the present invention will become apparent from the following specification.
