The wind pressure against a roof or an entire home can be enormous.

Metal roof thermal expansion.

Standing seam roof systems were designed to allow roof movement and should be specified when roof movement is expected to be a problem due to the design of the. Also the surface temperature of metal roofing materials can range from 25 degrees. The rate of thermal movement varies by the type of metal installed and temperature of the base metal. Thermal expansion contraction is responsible for most roof leaks.

A material experiencing a rise or decrease of temperature expands or contracts respectively this poses an interesting challenge when it comes to designing metal panel roof assemblies. A formed metal component anchored to the building substrate used to secure two pieces of metal to each other or to secure metal shingles or standing seam roofing but can move with the metals expansion to allow for thermal movement. The following table provides the coefficients of linear thermal expansion and representative thermal expansion values for various building materials where possible the values were taken directly from manufacturer technical data sheets and reflect the coefficients of linear thermal expansion for specific representative products. It is important to note ambient air temperature will differ from the temperature of the metal and direct solar radia tion plays a major role in this process.

Metal roof thermal expansion. Expansion and contraction factors often are overlooked or regarded as insignifi cant in metal roof system design and construction. It might be the wind. For example expansion and contrac tion can cause metal components to.

In the long run a properly designed weather tight roof will cost less than an improperly designed leaky low cost roof. Metal roof systems can be the least forgiving of all roof sys tems if provisions for expansion and contraction are neglected. As the lumber expands it moves and it will rub against other pieces of wood that aren t moving at the same rate.

Years ago as a young builder i almost got blown off a roof while trying to carry a sheet of 4 by 8 plywood. You can demonstrate this to yourself quite easily by trying to carry something large and flat on a windy day.
