Wind Noise

Roof noise triggered by the wind can take several forms:

  • Underlay flutter,
  • Banging of the roof itself, or things against the roof,
  • Vibration of flashings.


Underlay Flutter

Underlay flutter will be perceived as a high-pitched noise. Depending on its origin, it can be minimised using various techniques, for example:


  • If it is coming from the eaves, cutting the underlay back from the spouting and installing an eaves flashing.
  • If it is coming from the body of the roof, installing a high front gutter.
  • Installing spray-on foam insulation.

Wind Banging

Wind banging can be the pan drumming or banging against the sarking or purlin support. It normally only occurs with standing seam profiles and it is a function of the roof design, material thickness, and wind loads. These problems should be referred to the manufacturer or designer.

Flashing Vibration

Excessive movement or insufficient clearance between a penetration and the cladding may also cause noise.

Flashing vibration can be a whistling noise or a high-pitched sound like an engine, known as motor boating. The edges of all flashings should have a stiffening fold and the vertical face should be fixed to the structure or wall cladding to avoid vibration.
