Squeaky Noise In My Attic

Sounds like silent knock on the attic.
Squeaky noise in my attic. Find the noisy turbine and apply the lubricant to the moving parts of the turbine. Throughout the cooler months mice tend to enter our homes or businesses searching for food and shelter. Be sure to lubricate the bearings. But when we opened the cabinet where the vent goes up in the stove we found a hole as big as a golf ball.
The air vent in my room is no where near the noise and the noise is not coming from a ceiling fan. The bad news is once inside mice tend to reproduce quickly causing an infestation before you even knew it was happening. Place the stepladder under the attic access space. No sign of vent damage.
Every morning between the hours of about 7 30 8 30 there is a persistent type of squeaking from the attic above my bed. These are located in the track where the pipe coming out of the roof meets the spinning part of the vent. Twice i heard noise in the attic above my bedroom. Remove the current worn out bearings and replace them.
We do have a tile roof and 6 year old house. Wall or attic sounds. Attic fans also have small ball bearings that help lubricate the fan s movement. If this is the main attic noise you ve been hearing it could be mice.
This can cause the fan to start making constant noise and in some cases even a loud squealing sound. Immediately shut off the system then wait a few moments and turn it back on. Due to regular wear and tear these bearings can become worn out or lose their lubrication ability.
