Turbine fans are an important tool in ventilating an attic. Operating without electricity, they offer consistent passive ventilation that allows excess heat to pass out of the attic's interior and into the outdoor environment. These systems also reduce the risk of mold growth, condensation and mildew in the attic. On occasion, the turbines may develop an annoying squeaking sound that can be heard from within the house or while the home's occupants are enjoying time in the yard. Experienced Fort Worth roofing experts can troubleshoot the cause of the noise and fix the problem so that homeowners can enjoy peace and quiet while their fans are spinning.
Contact between the metal bearings is a common cause of irritating turbine fan sounds. To stop the metal parts from coming into contact with one another, roofers can apply a coating of lithium grease. The grease may come in a spray or solid form that is spread across all moving parts of the fan. This protective lubricant also acts to help prevent the development of rust. For maintenance reasons, the grease as well as a silicon spray should be applied once each year. These two materials work together for optimal protection against corrosion and noise.
A loss of lubricant around the fan's base is another reason why the system could be producing too much noise.

A silicon spray on lubricant is often the solution of choice for roofers fixing this problem. The lubricant is sprayed across the fan's pivot points, which are located near the bottom where the fan's base intersects with the attic's interior. The silicon should be left on for a few minutes so that it can soak in and penetrate into the materials. The roofers will rotate the turbine during this period so that the lubricants can be distributed throughout all of the bearings and internal parts. Any excess is wiped off with a soft cloth about 10 minutes after application.
Loose bolts or screws could also be the cause of noisy turbines. After a few years of regular operation, the screws or bolts may work themselves a little bit loose. Extreme temperature changes can also push these fasteners out of place. Roofers can refasten the screws or bolts with the appropriate hand tools. On occasion, the fasteners may develop rust. In this case, the roofers will replace them with intact screws or bolts. The new fasteners will have a dab of silicon caulk applied to their tops to prevent any new rusty spots from developing.
