      Why PlazaDeck Systems?

      For a surprisingly modest investment, GAF PlazaDeck Waterproofing Systems add usable square footage to your property and possibly increase the resale value.


      Benefits of PlazaDeck Systems include:
      • Diamond Pledge™ Guarantee:  The industry’s premier roof guarantee with true “edge-to-edge” coverage. Includes coverage for the entire Weather Stopper™ Integrated Low-Slope Roofing System.

      • WellRoof® Guarantee Advantage:  The single best way to extend the life of your roof is to perform regular inspection and maintenance. GAF believes so strongly in this practice that it offers its unique WellRoof® Advantage program: a 25% extension of the length of your Diamond Pledge™ Guarantee — FREE — when you invest in a regular maintenance and inspection plan!1
      • Factory-certified Contractors:  Less than 3% of roofing contractors earn membership into the GAF factory-certified contractor program. GAF workmanship guarantees are available only through this exclusive group.
