Grease doesn’t stop at your exhaust hood. Every time your commercial kitchen runs, grease-laden air moves through your exhaust system and exits through the rooftop fan, depositing grease directly onto your roof surface. Over time, that buildup eats through roofing membranes, voids warranties, creates a direct fire hazard, and can lead to roof replacement costs exceeding $100,000. Hood Boss supplies and installs commercial rooftop grease containment systems designed to intercept grease before it reaches your roof. As part of our Kitchen Exhaust Cleaning program, we inspect your rooftop at every service visit and recommend the right containment solution for your specific fan configuration and facility type.
Restaurant owners and facility managers often focus on what’s happening inside the kitchen, and overlook the rooftop entirely. That oversight is expensive.
Rooftop grease containment is not a one-time install, it’s an ongoing part of kitchen fire safety compliance. Hood Boss integrates rooftop monitoring into every kitchen exhaust cleaning visit. Our technicians document the condition of your roof and containment system in the after-service report, flag any buildup or saturation, and replace worn components proactively, before grease reaches the roof surface.
This means you always have a current record of your rooftop condition, documentation ready for fire marshal and insurance reviews, and a containment system that’s maintained on schedule without requiring a separate service call.
We supply and install multiple rooftop grease containment systems from Omni Containment Systems, one of the industry’s most trusted manufacturers. We’ll assess your exhaust fan type, discharge pattern, and rooftop layout to match you with the right unit. See also: Hinge Kit Installation and Access Panels; two additional products we install to support full exhaust system compliance.
Hood Boss installs three primary Omni Containment products. Each is engineered for a specific fan type and discharge pattern. We’ll identify which system is right for your rooftop during a site assessment.
The Omni Grease Gutter is the right solution when your up-blast exhaust fan discharges grease from all four sides of the fan housing. It attaches directly below the fan to catch grease before it contacts the rooftop membrane.
The Grease Gutter is the most widely deployed commercial rooftop grease containment solution in the industry and is the starting point for most Hood Boss facility assessments. Request a quote to find out if it’s right for your kitchen.
When the Grease Gutter isn’t the right fit, due to fan placement, discharge pattern, or rooftop configuration, the Roof Guardian™ is our recommended solution. It’s the most versatile rooftop grease containment system in our lineup and can be built to accommodate almost any commercial exhaust fan size or application.
The Roof Guardian’s elevated design is a meaningful improvement over legacy systems. Because it clears the roof and allows visual inspection underneath, technicians can spot any grease reaching the membrane before it causes damage, and document findings in the service report. Learn more about what our team checks during visits on our Kitchen Exhaust Cleaning page.
Not every up-blast exhaust fan discharges grease from all four sides. Some units discharge only from the drain spout, a narrower exit point that doesn’t require full perimeter coverage. The Omni Side Kick is built specifically for this configuration.
Not sure which unit your exhaust fan requires? Hood Boss will assess it during a site evaluation and identify the discharge pattern before recommending a system. Contact us to schedule an assessment.
No two rooftops are identical. Fan model, age, discharge pattern, roof pitch, and local weather conditions all influence which containment system performs best. Hood Boss assesses your specific situation before recommending a product.
Our evaluation process includes reviewing your exhaust fan type and manufacturer specs, identifying the grease discharge pattern (360° vs. drain spout only), inspecting current rooftop grease accumulation, assessing your roofing material and existing warranty terms, and recommending the Omni unit that provides the right coverage at the right cost.
Once installed, the system is maintained as part of your regular Kitchen Exhaust Cleaning schedule. Pad replacements, unit inspections, and rooftop condition reporting happen automatically, no additional scheduling required on your part.
NFPA 96 requires the entire commercial kitchen exhaust system, including the rooftop termination and surrounding areas, to be kept free of grease accumulation. This includes the surfaces around and beneath rooftop exhaust fans.
A grease-covered rooftop is a code violation. Fire marshals and insurance auditors routinely check rooftop conditions during compliance reviews. Facilities with documented grease accumulation around the exhaust fan can face citations, coverage denials, or forced shutdowns.
Hood Boss grease containment systems, combined with our regular service documentation, give you a defensible compliance record. Every service report notes rooftop conditions and any recommended corrective actions.
Replacement frequency depends on cooking volume and menu type. High-volume fryers and charbroilers generate far more grease than lighter cooking operations. Hood Boss assesses pad saturation at every service visit and replaces them as needed, no separate appointments required.
If you operate a commercial kitchen with an exhaust hood, the answer is almost certainly yes. NFPA 96 requires that grease not accumulate around rooftop exhaust fans. Whether you need a Grease Gutter, Roof Guardian, or Side Kick depends on your fan type and discharge pattern, Hood Boss determines this during a site evaluation.
Yes, and that’s exactly the risk a containment system prevents. Uncontained grease is what voids most commercial roof warranties. A properly installed and maintained containment system protects your roof membrane and provides documented evidence of proactive maintenance, which most warranty programs require.
Rooftop containment is a separate installation, but its ongoing maintenance, pad inspection and replacement, is fully integrated into your regular kitchen exhaust cleaning service schedule. No extra service calls needed.
Rooftop grease containment is one piece of a fully compliant exhaust system. Hood Boss supplies and services a complete range of products to keep your kitchen safe and code-compliant:
