Roof Guardian Grease Containment System

The Roof Guardian has a four-layer grease filtration system to help keep your roof grease-free. The top filter is porous and helps grease disperse evenly to the lower filter levels. The second layer is made of hydrophobic material which will catch and absorb grease while allowing water to run through. The third layer is plastic-backed and absorbent while adding extra rooftop protection. The fourth and final layer is the same porous material as the top layer and will keep grease saturated filters off of the roof.

Available in any size to accommodate any brand of roof-mounted ventilator fans.
