Convection refers to the process by which heat is transferred through the movement of air or other fluids. In the context of roofing, convection can occur when air or other fluids circulate between the roofing materials and the underlying structure, or within the roofing materials themselves.

Convection is an important factor to consider in the design and installation of roofing systems, as it can affect the overall energy efficiency and performance of the building. High levels of convection can result in heat loss or gain, depending on the direction of the air or fluid flow, which can result in increased energy costs and reduced comfort for building occupants.

To minimize the effects of convection in roofing systems, a variety of strategies may be employed. These may include the use of insulation materials to reduce the circulation of air or fluids between the roof and the building interior, as well as the use of ventilation systems to promote air circulation and minimize the buildup of heat.

Proper installation and maintenance of a roofing system is also important for minimizing the effects of convection. The roofing materials should be installed in such a way as to minimize gaps and spaces that can allow for the circulation of air or fluids. The materials should also be inspected regularly to ensure that they remain properly sealed and in good condition, and that any ventilation systems are functioning properly.
