Abstract
A roof vent device for providing air intake to the valley of a roof where the valley of the roof extend from the soffit to the roof ridge. The device comprises a support surface mounted in contact with valley flashings on the roof. The support surface extends axially along the hip beam of the roof and joined by the jack rafters. At least one additional layer not as wide as the support surface but axially equal in length increase the space between the hip beam and the device's central axis. The additional layers do not extend as far as central axis of the support surface, thus creating an open space between the hip beam and the support surface. A pivot point in the central axis of the support surface permits the support surface to conform to any valley flashing used.
Claims18
A roof vent device or providing air intake to the valley of a roof in combination with a valley flashing, hip beam and jack rafters, comprising:
- a support surface axing a central axis and sized for contact with a valley flashing and mounted under said flashing on a roof and in contact with said jack rafters, said support surface extending axially along the hip beam of the roof and joined to the jack rafters for the length of said central axis without providing an opening between said rafter and said flashing at the ends of said flashing;
- at least one additional layer having a smaller width than said support surface and axially equal in length thereto for increasing space between said hip beam and said central axis without providing air access to the outside, said at least one additional layer being mounted on said support surface along the length and on the side away from said flashing thereof and spaced from said central axis to create an open space between said hip beam and said support surface;
- and
- a pivot point formed along said central axis of said support surface to permit said support surface to conform to said valley flashing.
A roof vent device for providing air intake to the valley of a roof in combination with a valley flashing, hip beam and jack rafters, comprising:
- support surface means sized for contact with a valley flashing and mounted under said flashing on a roof and in contact with said jack rafter and having central axis, said support surface extending axially along the hip beam of the roof and joined to the jack rafters for the length of said central axis without providing an opening between said rafter and said flashing at the ends of said flashing;
- at least one additional layer means for increasing space between said hip beam and said central axis without providing air access to the outside and having a smaller width than said support surface means and axially equal in length thereto said at least one additional layer means being mounted on said support surface means along the length thereof and on the side way from said flashing and spaced from said central axis to create an open space between said hip beam and said support surface;
- and
- pivot point means formed along said central axis of said support surface for permitting said support surface means to conform to said valley flashing.
A method for pro ding air intake to the valley of a roof having a valley flashing, a hip beam and jack rafters, comprising the steps of:
- mounting a roof vent device to said roof, said device including a support surface having central axis on a valley flashing and mounted under said flashing on a roof and in contact with said jack rafters, said support surface extending axially along the hip beam of the roof and joining said support surface to the jack rafters for the length of said central axis without providing an opening between said rafter and said flashing at the ends of said flashing;
- at least one additional layer having a smaller width than said support surface and axially equal in length thereto for increasing space between said hip beam and said central axis without providing air access to the outside, said at least one additional layer being mounted on said support surface along the length thereof and on the side away from said flashing and spaced from said central axis to create an open space between said hip beam and said support surface;
- and a pivot point formed along said central axis of said support surface to permit said support surface to conform to said valley flashing;
- said roof vent device forming a space to provide a maximum amount of air into the roof and the least amount of heat contrast between the inside and outside of the roof is achieved.
