Attic Vent Noise

Remove the screws holding the vent in place.

Attic vent noise. Be sure to lubricate the bearings. Find the noisy turbine and apply the lubricant to the moving parts of the turbine. While hardly anybody agrees on the best roof ventilation system everybody agrees some roof vents do hardly any good at all. My intention being to move the fan assembly further into the attic.

Cut through any sealer that may be present. Lift up the edges of the surrounding roof shingles so you can see the edges of the vent. If the noise drives you crazy new spring loaded backdraft dampers 9 to 30 depending on the size should solve the problem. Place the stepladder under the attic access space.

Due to regular wear and tear these bearings can become worn out or lose their lubrication ability. Usually this happens if the vents are straight across from each other so the sound doesn t have to turn any corners on its way between the two rooms. Climb onto the roof and locate the vent that is causing the noise. These are located in the track where the pipe coming out of the roof meets the spinning part of the vent.

The shape of the duct connecting vents in two different rooms to each other is enabling the passage of sound. Well there are three main reasons for noisy vents. An attic fan works by exchanging the hot air in your attic space for fresh air pulled through the vents. This can cause the fan to start making constant noise and in some cases even a loud squealing sound.

This will help to avoid premature damage to the shingles or mold building up in moist hot. Attic fans also have small ball bearings that help lubricate the fan s movement. I have roof vents so i have roof ventilation. The majority of roofing experts agree that ridge vents are the most effective and cost effective roof vents available.

Remove the old vent. Climb the ladder remove the access panel and enter the attic. Often a stiff wind will open vent dampers causing them to periodically clang shut. Noise was an issue i close the closet door to eliminate the hole to the attic effect during the day and i discovered flex duct in 18 diameter is hard to come by.

Remove the current worn out bearings and replace them.
