Roof Turbine Vent Not Turning

This is not a good idea.

Roof turbine vent not turning.

Walking around my soffits yes i do have soffit vents and from the attic i can see sunlight in. 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. It s not uncommon for insulation to have been jammed tight out to the edge of the roof. They sell foam channels you can staple to the underside of the room to allow for airflow while still allowing insulation to be installed.

Every turbin in my neighborhood is turning and mine may slowely turn. The one thing i ll mention is that turbine vents need to be installed perfectly level. Also barely using my finger of course they spin freely no noise etc. This is a bad thing because it blocks the air flow.

When they re not installed level they don t turn. Normally the force of even slight breezes will cause the turbine vent to spin. Climb up into your attic and look at the vents from the inside. Fortunately it is a very fixable problem and depending on your property perhaps even one you can fix yourself.

The turbins do not turn much at all. My attic turbines are not turning step 1. I ve gone on the roof and white lithium greased both and but a level on them and they are pretty close to level. 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.

Do i have a low pressure system. The 14 inch diameter unit could provide a complete air change in the attic every 14 minutes at 15 mph. Both turbins are only about 4 years old. If the vents are blocked by insulation boxes or.

To relieve this pressure the vacuum may pull air from the inside of your home. 2 of my 3 turbine vents on my roof won t turn unless there s a stronger wind. I have sophits and gabel vents. A turbine may fail to spin if the bearings become rusty or.

Examine the turbine from the exterior from the roof. I have taken them off and oiled them and they spin freely and easily when spun with the hand. As it spins the air blown from the vent is strong enough to blow rain away from the openings between the fins. 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.

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.
