Securock Cement Roof Board

USG Corp. has introduced SECUROCK® Cement Roof Board: a durable, sustainable and high-performance roof board ideal for use in low-slope roofing systems. This product is environmentally sustainable, as its lower weight ultimately reduces embodied energy and emissions. SECUROCK enhances the entire roofing system as both a cover board and as a parapet, fire, or thermal barrier roof board. It can be used with a variety of membranes and systems including fully adhered and mechanically attached systems, but it is ideal for applications such as liquid-applied membranes and cold mastic modified bitumen. Due to its cement base, this product provides superior compressive strength, water durability and mold resistance. For more information, visit
