These gaps enable different parts of the roof to move and rub against each other, producing the familiar creaking sounds in wind. Here is how it comes about: exposed building materials and individual parts such as the meeting points between the screws/nails and the roofing material shrink or increase in size by the temperature changes.Īnd since different materials expand and contract at different rates, tiny gaps are created in areas where any two different materials meet. This rate can in turn be determined by the size of the change in temperatures. If yes, then the noise is more likely to be a result of the normal heat-induced expansion and contraction.Įxpansion and contraction of materials do occur in cold conditions as well – it will depend on the rate of expansion/contraction. Thermal Expansion/Contraction and Movementsĭoes your roof make more noise on a hot day than on a cold one? Here are the main causes of a noisy roof on a windy day: 1. Most of the wind-related noises occur on the roof. Besides the material of the roof (metal roofs, for example, are always noisy), it could be the age of the home or overhung tree branches sweeping the roof in wind. It’s hard to tell by the sheer sound of it. (Short Answer) Why Does Your Home Creak When the Wind Blows?
