Redefine Performance with DensDeck® Roof Board
An FMI study found that adding a cover board to a single-ply membrane roof increased its median life expectancy, reduced maintenance costs, and significantly boosted the percentage of roofs meeting their full life expectancy.
Cost Savings
Owners using a cover board as part of their low-slope commercial roof assembly saved an average of $1.40 per square foot in O&M costs over the roof’s lifetime.1
Long Lasting
Roofs with a cover board met owners life expectancy nearly twice as often as roofs without a cover board (86% vs. 52%).1
4 Years Longer
The median life expectancy of a commercial roof using a cover board increased by four years.1
