Benefits to your roofing system and the entire building
The compressive strength of DensDeck® Roof Boards helps fight the risk of punctures from heavy foot traffic and dropped tools during maintenance. This means fewer callbacks for you and more satisfied stakeholders.
Cover boards extend the life of a roof. 86% of single-ply roofs with a cover board met owner life expectancy compared to only 52% of roofs without a cover board.¹
DensDeck® Roof Boards are noncombustible per ASTM E136. Their gypsum core and fiberglass mat facers help slow the spread of flames and smoke.
DensDeck® Roof Boards’ gypsum core helps provide a rigid, consistent substrate for attaching photovoltaic systems and more rooftop installations.
Using rigid gypsum cover boards like DensDeck® Roof Boards can help absorb sound, which means occupants hear less outside noise.

One of the most dangerous threats to a commercial low-slope rooftop is the risk of catching fire. See how DensDeck® Roof Boards perform in fire testing.
When heavy winds move over and around a building, they create low pressure above the roof. Wind uplift can cause membrane delamination and fastener withdrawal. DensDeck® Roof Boards give you a rigid base of support, a superior bonding surface and enhanced strength to mitigate damage.
While small punctures may not look threatening, they can lead to serious problems over time. See how DensDeck® Roof Boards outperform HD ISO in puncture tests.
DensDeck® StormX® Prime Roof Board was the first cover board to be FM classified for Very Severe Hail (VSH) in approved single-ply assemblies. It helps provide impact protection to both the membrane and insulation of your roofing system.
