Off-ridge roof vent with internal water diverter

Abstract

The off-ridge roof vent with an internal water diverter includes a throat, a hood and a water diverter. The throat has a front throat wall, a rear throat wall and a pair of longitudinally opposed throat sidewalls. The throat has open upper and lower ends. The hood has an upper hood wall that is convex upward, a pair of longitudinally opposed hood sidewalls and a lower hood wall. A lower end of the hood has a rear portion, a central portion and a front portion, the rear portion being open, aligned with, and in open communication with the open upper end of the throat. The lower hood wall defines the central portion and projects forward from the front throat wall. The front portion is open, having a perforated grating mounted therein. A water diverter extends from the front edge of the lower hood wall and slopes above the grating.

Description

BACKGROUND1. Field[0001]The disclosure of the present patent application relates to attic and roof ventilation, and particularly to an off-ridge roof vent with an internal water diverter.2. Description of the Related Art[0002]Numerous designs for attic and roof vents are known for providing ventilation to areas beneath building roofs. The ventilation of such areas is desirable to reduce the accumulation of heat in the summer, and to reduce the accumulation of moisture at all times of the year. In providing ventilation, it is important to prevent the entry of water into the building through the vent. It is also important to prevent debris and small animals from entering the building through the vent.[0003]A common type of off-ridge roof vent uses a simple duct having a baffle mechanism over the top to prevent the entry of rain into the building. A variation of this simple design is the turbine-type roof vent, which uses a rotating element on the exterior of the duct and interior baff...

AI Technical Summary

Benefits of technology

This patent describes an off-ridge roof vent that is designed to prevent water from entering the roof through the vent. The vent has a throat, a hood, and a water diverter. The hood is attached to the throat and has a curved shape that helps to direct airflow smoothly. The water diverter is located in the hood and prevents water from getting inside the throat. The roof vent can be mounted on a roof using screws or other fasteners. Overall, this invention helps to keep water out of roofs and ensures proper ventilation.

Problems solved by technology

However, such off-ridge roof vents provide only a limited area through which air and moisture may escape from the structure.

Further, such designs typically extend a considerable height from the surface of the roof, making them vulnerable to being knocked from the roof by tree limbs, wires, or simply the wind itself.

However, such low profile designs suffer from a number of disadvantages.

For example, such vents are typically vulnerable to damage by wind or by impact from debris.

Typically, damage from the wind to such vents is in the form of bent or deformed top pieces or hoods.

Such damage makes the vent more easily penetrated by rain and debris, since portions of the vent opening are enlarged, and the damage often results in deformation of those portions of the vent that interface with the surface of the roof, thus interfering with the proper sealing of the vent to the roof surface.
