Roof Turbine Not Moving

My attic turbines are not turning step 1.

Roof turbine not moving.

Walking around my soffits yes i do have soffit vents and from the attic i can see sunlight in. Climb the ladder remove the access panel and enter the attic. A small 12 inch diameter turbine vent with a constant wind speed of 5 miles per hour mph can remove 347 cubic feet of air per minute cfm from the attic space. 2 of my 3 turbine vents on my roof won t turn unless there s a stronger wind.

Climb up into your attic and look at the vents from the inside. If air sealing hasn t been performed in the attic they ll pull air into the attic from inside the house and shouldn t be used that bears repeating. This is a standard turbine vent. These are located in the track where the pipe coming out of the roof meets the spinning part of the vent.

Since turbines are attached directly to attic spaces they can siphon. A turbine may fail to spin if the bearings become rusty or. Also barely using my finger of course they spin freely no noise etc. Be sure to lubricate the bearings.

I ve gone on the roof and white lithium greased both and but a level on them and they are pretty close to level. Do not install turbine vents if the attic has not been professionally air sealed. Find the noisy turbine and apply the lubricant to the moving parts of the turbine. Depending upon the diameter of the vents and the wind speed outdoors the turbines can expel vast quantities of humid air before it becomes a problem.

Roof vents need to move hot humid air from the attic to the outdoors so that humidity doesn t build up and cause mold rot or other moisture problems that findlay roofing regularly sees when dealing with attic issues. The other thing about turbine vents is that they really do pull air out of the attic. The faster the wind speed the faster the turbine rotates. Do i have a low pressure system.

Just hot air rising out of one will make it spin. Examine the turbine from the exterior from the roof. The benefits of using a turbine.
