Roof Turbine Vent Not Turning

As it spins the air blown from the vent is strong enough to blow rain away from the openings between the fins.

Roof turbine vent not turning. The wind has to blow pretty hard for them to turn good. Walking around my soffits yes i do have soffit vents and from the attic i can see sunlight in. Normally the force of even slight breezes will cause the turbine vent to spin. I ve gone on the roof and white lithium greased both and but a level on them and they are pretty close to level.

Every turbin in my neighborhood is turning and mine may slowely turn. This is a bad thing because it blocks the air flow. The turbins do not turn much at all. Climb up into your attic and look at the vents from the inside.

If there is not enough soffit air coming in then the vents may create a partial vacuum in the attic space. 2 of my 3 turbine vents on my roof won t turn unless there s a stronger wind. This is not a good idea. They sell foam channels you can staple to the underside of the room to allow for airflow while still allowing insulation to be installed.

Also barely using my finger of course they spin freely no noise etc. The majority of the time a squeaking roof turbine vent is caused by the lubricant in the bearings drying out causing various metal parts to rub against each other which in turn generates that unpleasant squeaking noise you hear. One static vent style is the turbine vent which uses wind to power its enclosed fan all it takes is a light breeze to rotate the blades and suck heat out of the attic view example on the home. It s not uncommon for insulation to have been jammed tight out to the edge of the roof.

My attic turbines are not turning step 1. The one thing i ll mention is that turbine vents need to be installed perfectly level. When they re not installed level they don t turn. A single 12 inch diameter turbine vent could provide a complete change of air in the attic space every 52 minutes if the outside breeze was just 5 mph.

Examine the turbine from the exterior from the roof. A turbine may fail to spin if the bearings become rusty or. I ve never been a huge fan of turbine vents because i have it in my head that they may end up causing some of the same problems that powered roof vents do but the fine folks at complete building solutions swear by em and i trust those guys so i won t complain about turbine vents. I have taken them off and oiled them and they spin freely and easily when spun with the hand.

To relieve this pressure the vacuum may pull air from the inside of your home. Fortunately it is a very fixable problem and depending on your property perhaps even one you can fix yourself. I have sophits and gabel vents. Both turbins are only about 4 years old.

The 14 inch diameter unit could provide a complete air change in the attic every 14 minutes at 15 mph.
