Rooftop turbine vents is a type of an exhaust vent. They have fins that open when they turn in the wind, and this spinning action creates suction that draws hot, humid and stale air outside. In most situations, turbine vents need little or no maintenance, but it’s not impossible for problems to occur as listed below:

1. Obstructions or rust in vents :

Normally the force of even a slight breeze will cause the turbine vents to spin. As it spins, the air blown from the vent is strong enough to blow rain away from the openings between the fins. If the vent is rusted, it may be sticking and not turning as it should and this can lead to water infiltration which can lead to the vent leaking. There may also be something near or in the vent that is stopping it from turning properly.

Solution from Curvent's Maintenance Team :

We will Inspect each rooftop turbine vent and remove obstructions if any. Should there be rusted turbine vents we will replace them.

2. Loose Connections

In very high winds a turbine vent may pull loose from its standpipe. The top portion of some turbine vents are typically installed with a friction fit to the lower standpipe portion. If the flange that connects the pipe to the roof’s sheathing is poorly anchored it could provide an opening for rain.

Solution from Curvent's Maintenance Team :

Using sheet metal screws we will make sure that the top (spinning) portion is securely anchored to the standpipe of the roof turbine vent. We will inspect and secure the flashing, if it is loose, with rust-resistant screws or roofing nails. After this we will seal the exposed fastener heads properly with silicone caulk or roofing cement.

3. Unsealed Joints and Fasteners

During installation, turbine vents are sealed at several points to prevent water penetration. The base of the vent, where the flashing meets the stack, the nail heads, the bead joining the upper and lower sections, and the vertical seams in the stack are typically sealed with roofing cement or silicone caulk.

Solution from Curvent's Maintenance Team :

Inspect turbines because these seals can deteriorate over time and may need to be reapplied.

4. Improper Flashing

There could be a leak around the base of the vent.

Solution from Curvent's Maintenance Team :

Reattach any raised portion of the flashing, sealing all edges and fasteners with caulk or roofing cement. If the flashing is corroded, it might have holes that in water; in this case, replace the entire vent.
