The longevity of a metal roof system is greatly influenced by the ability of the roof to move slightly based on thermal changes. Properly designed metal roof systems can last many years, but an improperly designed roof may show signs of roof failure in as little as five years.
The effect of thermal movement is influenced by the type of metal roof systems installed and the temperature of the base metal. The temperature of the metal can differ greatly from the air temperature. Thermal movement must be considered during the initial installation. Repairs to improperly designed systems are seldom satisfactory and often lead to a full roof replacement much sooner than originally planned on.
The underlayment used is also another important consideration. The underlayment must be able to allow for proper thermal movement and can also be used to protect the underside of the metal panels.
