Attic Vent Noise

These are located in the track where the pipe coming out of the roof meets the spinning part of the vent.

Attic vent noise.

This can cause the fan to start making constant noise and in some cases even a loud squealing sound. Well there are three main reasons for noisy vents. Climb the ladder remove the access panel and enter the attic. Find the noisy turbine and apply the lubricant to the moving parts of the turbine.

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. Attic fans also have small ball bearings that help lubricate the fan s movement. 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. Lift up the edges of the surrounding roof shingles so you can see the edges of the vent.

Due to regular wear and tear these bearings can become worn out or lose their lubrication ability. Remove the screws holding the vent in place. Remove the old vent. Roof vents and power roof vents are made to work in conjunction with vented soffits so that outside air.

An attic fan works by exchanging the hot air in your attic space for fresh air pulled through the vents. This will help to avoid premature damage to the shingles or mold building up in moist hot. Be sure to lubricate the bearings. 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. While hardly anybody agrees on the best roof ventilation system everybody agrees some roof vents do hardly any good at all. The shape of the duct connecting vents in two different rooms to each other is enabling the passage of sound. Take for example ridge vents.

The majority of roofing experts agree that ridge vents are the most effective and cost effective roof vents available. Climb onto the roof and locate the vent that is causing the noise. Remove the current worn out bearings and replace them. My intention being to move the fan assembly further into the attic.

Often a stiff wind will open vent dampers causing them to periodically clang shut.
