Abstract

A roof vent member with an integrated fan assembly is disclosed. The roof vent member includes an upper plate having fasteners that extend downward below a roof deck when installed to allow for access to the fan assembly from underneath the roof deck. Thus, the fan assembly may be installed, removed, replaced, maintained, etc. from underneath the roof without having to get on the roof or otherwise disrupt the roof envelope. The roof vent may include the upper plate, a subflashing, the fan assembly, sealing elements, screens, and other features. A secondary roof vent member may be included which may include solar panels. Associated methods of using the vent members, such as installing, removing, and replacing the vent member or various components thereof, are further disclosed.

8. The roof vent of claim 7, wherein the secondary vent member is configured to couple with the roof vent member.

9. The roof vent of claim 7, wherein the secondary vent member is configured to couple with the roof deck.

10. The roof vent of claim 7, wherein the roof vent is one of a composition vent, a flat vent, an S-shaped roof vent, and an M-shaped roof vent.

11. The roof vent of claim 7, further comprising a solar panel coupled with the secondary vent member.

12. A roof vent member, comprising:

an upper plate comprising;

an upper plate body having a lower surface;

a first opening extending through the upper plate body; and

a plurality of fasteners positioned around the first opening and projecting generally downward from the lower surface;

a subflashing comprising;

a subflashing body comprising a plurality of side members;

a second opening extending through a central portion of the subflashing body, the plurality of side members surrounding and extending radially outwardly from the second opening; and

a first plurality of access holes extending through the side members around the second opening, wherein the side members are configured to provide support to and allow positioning of the subflashing above a roof deck when the subflashing is mounted on an upper surface of the roof deck, and wherein the upper plate body is configured to be positioned above the subflashing when the subflashing is mounted on the upper surface of the roof deck; and

a fan assembly comprising a fan, fan housing including sidewalls, and a motor, wherein a second plurality of access holes extend through the fan housing,

wherein the fasteners of the upper plate extend through the first plurality of access holes of the side members and the second plurality of access holes of the fan assembly to couple the upper plate and the fan assembly to the subflashing, with the subflashing positioned between the upper plate and the fan assembly, wherein the subflashing, upper plate and fan assembly are configured, such that when the fan assembly is coupled to the subflashing and the upper plate, and the subflashing is mounted on the upper surface of the roof deck, at least a first portion of the sidewalls of the fan housing of the fan assembly is positioned entirely within a roof deck opening in a plane of the roof deck and

wherein the upper plate, the subflashing, the fan assembly, and the plurality of fasteners are further configured such that the plurality of fasteners extend through the roof deck opening when the subflashing is mounted on an upper surface of the roof deck.

13. The roof vent member of claim 12, wherein the plurality of fasteners are of a unitary construction with respect to the upper plate body.

14. The roof vent member of claim 12, further comprising a plurality of complementary fastening elements configured to removeably attach to distal ends of the fasteners to couple the upper plate, the subflashing and the fan housing.

15. The roof vent member of claim 12, wherein the upper plate, the subflashing, and the fan assembly are further configured to allow the fan assembly to be removed and replaced from under the roof deck when the subflashing is mounted on the upper surface of the roof deck.
