What Are Cover Boards ?
A cover board is a material layer that is placed on top of a flat roof’s deck and below the roofing system. It provides a smooth surface for installing roofing materials and protects the roof deck from damage. Cover boards can also improve a building’s energy efficiency by adding an insulating layer.
Roofing cover boards are used to create a watertight covering that protects the interior of a building
