Omega Roof Exhaust Vent

The Omega roof exhaust vent is a roof-mounted vent that lets trapped warm air and moisture escape from the roof cavity. It is a simple passive unit, which means there are no fans or wiring to install or maintain. The vent sits on the roofline and gives the moist air that rises into the roof space a way out, which helps stop condensation forming on the sarking and framing.

Key Features

• Passive roof exhaust vent with no moving parts
• Allows trapped warm air and moisture to escape the roof cavity
• Reduces condensation and heat build-up under the roof
• Weatherproof design prevents rain ingress while air flows
• Suits tiled, metal and sheet roofing
• Lightweight and quick to fit

Installation

The vent mounts at a high point on the roof where warm air collects, and the flashing is fitted to the roof profile so water stays out. Fit it clear of roof penetrations and keep the area around the vent open so air can move freely. Because it is passive, there is no wiring to run and no switch to connect, which keeps the install to a straightforward roof job.

Applications

• Roof cavity ventilation on residential and commercial roofs
• Tiled, metal and sheet roofing systems
• Reducing condensation and heat build-up in the roof space
• Homes wanting a maintenance-free ventilation unit

What You Need To Complete The Job

Where the vent connects to a duct run, use flexible foil ducting to carry the airflow. For a corrugated metal roof, the Omega corrugated square roof vent is a matching outlet. Browse the Roof Ventilation range for the full selection.

Frequently Asked Questions

Does the Omega roof exhaust vent need power?

No. It is a passive vent that works by natural airflow. Warm air rises out of the roof cavity through the vent, so there is nothing to run and nothing to maintain.

What does it do for the roof space?

It gives trapped warm air and moisture a way out of the roof cavity. That reduces condensation, which protects the sarking, framing and insulation from damp damage, and it lowers heat build-up on hot days.

What roofs does it suit?

It suits tiled, metal and sheet roofing systems. The flashing fits the roof profile it is installed on, so choose the vent version that matches your roof type.

Is it weatherproof?

Yes. The vent is designed to prevent rain ingress while still letting air flow out, so it stays weathertight on the roof through rain and wind.

Can it be used for bathroom exhaust?

Yes. The vent can carry moist air from a bathroom exhaust out of the roof, which is important now that condensation can no longer be vented into the roof cavity. Run the duct from the fan to the vent with a direct, short route for the best airflow.

Does it need a duct connection to work?

The vent works on its own as a passive roof vent, letting warm air rise out of the roof cavity. Where you want active airflow, connect it to a duct run from a fan. In both setups the weatherproof flashing keeps rain out while the air moves through.
