Roof Noise Wind

If the surface the wind passes over has a consistent shape the disturbance becomes tonal and at certain frequencies very annoying.

Roof noise wind.

A wind fairing s goal is to reduce the wind noises which are brought about by the roof rack you have placed in your vehicle. The wind is flexing the rafters or trusses. The wind noise we hear from some roof racks is known as aeolian no ise and is produced by wind when it passes over or through objects. It seems to be just above the eaves and is a chattering noise as if a wave is breaking against the tiles and lifting them.

If i go in the loft the noise comes from high up middle ish area and transfers down the wooden frame to the ceiling. This flexing is what s. Someone somewhere must have had this same issue or know of someone. Although wind fairings do not eliminate the noise 100 percent it does minimize it significantly to prevent you from being distracted while you are driving.

Roof popping noise can be caused by the wind. Popping in the morning and evening is thermal expansion. Back to the noise though. Roof noises traced to wind see wind noises on roofs below squeaking and creaking traced to wind blown things attached to building exteriors such as signs antennas aerials weather vanes.

A roof rack wind fairing is an easy to install plastic shield that deflects wind away from the roof rack therefore reducing wind noise. Install a roof rack wind fairing if you already own a roof rack the best option to fix the wind noise and whistling is to install a wind deflector commonly referred to as a wind fairing. The builder has brought in the roofing contractor who seems to have no idea what is causing it. It is only when the wind is 30 mph ish or greater and it s as if someone is sitting on my roof occasionally tapping with a small hammer.

Roof noises may be described as those attributed to an obvious source. The patter or even the roar of falling rain or hail popping and cracking noises perhaps due to thermal expansion and contraction of roof coverings metal roofing or roof structure and transmitted noises from other external sources such as low flying aircraft or nearby trains or auto truck traffic from a nearby highway. One of which is a wind fairing.
