Compatible with single-ply or built-up roofing, Roof-Gard™ Pads can be used on all types of new or existing roofs to provide a safe, stable and maintenance-free walkway for access to air conditioning, water supply or electrical equipment. Roof-Gard™ is non-porous and is not affected by freeze/thaw conditions. When attached to the roof, Roof-Gard™ stays in place. Proper spacing eliminates water damming. They are easily cut to conform around drain openings or other roof obstructions and can be spot sealed with an ordinary caulking gun, reducing both labor and adhesive costs.
