For over a century, USG has led innovation in building and manufacturing solutions, shaping structures where we live, work and play. We passionately develop groundbreaking solutions that support communities around the world for generations to come.

USG makes several types of roof cover boards designed for different commercial roofing applications, including Securock® Gypsum-Fiber, Securock® UltraLight, Securock® Cement, and Securock® HD Polyiso cover boards. Each type varies in strength, weight, and moisture resistance to fit specific roofing system needs.

A roof cover board is a protective layer installed between the insulation and the membrane in a roofing system. It provides a smooth, stable surface for the membrane, enhances durability, and protects the insulation from damage during installation or maintenance.

Using a roof cover board helps protect the building from impact, fire, wind, and moisture damage. It increases the roof’s longevity, energy efficiency, and overall system performance by strengthening the roof assembly and maintaining the integrity of the insulation and membrane.
