The NEW G2 Grease Guard Rooftop Defense Systems are so effective at containing grease and oils from rooftop exhaust systems that Underwriters Laboratories Inc. has listed it for effectiveness and safety. This is the most oil absorbent, noncombustible, rainproof, structurally sound, closed, Listed, grease containment system on the market today. Uses changeable filter pads (requires annular changes).

Your facility may be subject to unnecessary liabilities, rooftop safety hazards and code violations. Grease and oil emitted onto your rooftop by your kitchen exhaust fans result in unnecessary roof leaks, costly roof repairs, unsafe work areas and even worse— FIRE.

Not only are grease and oil the source of roof deterioration, they are also extremely flammable. Over 98% of all restaurant fires are due in part to kitchen exhaust grease and oil. A spark can travel through the exhaust system to the roof surface resulting in extensive damage to your property and investment.


  • Fiberglass Filter Hold Down Poles & Stabilizers— for quick, easy and secure installation.
  • Top Pre-Filter— a pass-thru, fire-resistant, self-extinguishing filter constructed from an open cross section polymer.
  • Fire Shield— A fire-proof barrier that protects the roof & building from any potential exhaust system fire hazards.
  • Continuous Flashing— 22 gauge galvanized steel and molded corners provide a continuous perimeter that effectively deflects all effluents directly into the filter system.
  • Anodized Aluminum Frame (6063T-5)— complies with ASTM B-221.
  • Quick Corners— molded from UL Listed, corrosion, UV and temperature resistant copolymer with 22 gauge galvanized steel connector bars.


  • Maintenance recommended at least once per year depending on discharge volume.
  • G2 Grease Guard maintenance programs are custom tailored to meet the needs of both your organization and the individual needs of each of your stores. Your concept’s style of cooking, store volume, and the number of G2 Grease Guard units you have at each facility will determine the type and frequency of the maintenance program we design for you. You can rest assured that with the G2 Grease Guard National Account Maintenance Program in place, your facilities will be protected.
