Elevate DensDeck Roof Board 1/4 in. or 1/2 in. x 4 ft. x 8 ft. Gypsum
Elevate DensDeck is a gypsum roof cover board available in 1/4 in. and 1/2 in. thicknesses, each in 4 ft. x 8 ft. sheets, with a primed 1/2 in. option also offered.

Key Features:
- Gypsum core: Built with a gypsum core designed as a durable roof cover board over insulation.
- Three variants: Offered in 1/4 in. and 1/2 in. 4 ft. x 8 ft. sheets, plus a primed 1/2 in. version.
- Large sheet size: 4 ft. x 8 ft. sheets cover roof areas efficiently with fewer seams than smaller boards.

Expert Verdict — Reviewed by the SuperArbor Pro Desk
Cover boards like DensDeck protect insulation from foot traffic and give membranes a consistent bonding surface, which is why most good single-ply specs include them. Use 1/2 in. where durability and substrate strength matter most, and 1/4 in. where a thinner overlay is specified. Stagger board joints and fasten or adhere per the membrane manufacturer's requirements.
Handle and cut gypsum board with proper lifting technique, gloves, and eye protection; board edges can be heavy and sharp.
Order Elevate DensDeck roof cover board sheets in the thickness and finish your spec calls for.
