As of the writing of this article on Thursday, March 10th, 2022, the central Indiana daily forecast is predicting a high of 50 degrees today and snow showers and a low of 16 degrees tomorrow. From Saturday’s low of 18 degrees to 61 degrees on Monday, the wild temperature swings are forecasted to continue into next week. These large temperature changes in a short amount of time can cause “thermal shock” to various roofing and building components. Thermal shock refers to the damage that occurs when the roofing material on a building expands and contracts, in a short space of time, in response to temperatures rising or falling too fast.
Since these various building and roofing components are composed of different materials, they do not expand and contract at the same rate, which can lead to negative effects on varying types of roofing. This article will briefly explain how thermal shock affects various types of metal roofing.
