Service Scope

What Professional Rooftop Containment Covers

We install, maintain, and replace grease containment systems at your rooftop exhaust fans to protect your roof membrane and eliminate grease hazards.

What We Do

  • Containment system installation — pads, pillows, or corrals sized to your fan
  • Saturated-media replacement on a recurring schedule
  • Rooftop grease cleanup around the fan base
  • Drainage check to prevent pooling
  • Fan-base and roof-membrane inspection for grease damage

We coordinate containment service with your scheduled exhaust cleaning for efficiency.

What You Receive

  • Photo-documented service report
  • Fresh containment media installed and verified
  • Roof-protection notes and condition assessment
  • Replacement cadence recommendation
  • Documentation ready for fire inspectors, landlords, and insurance
Frequency

Replacement Cadence Aligned to Your System

Containment media replacement should align with your NFPA 96 Table 12.4 exhaust cleaning schedule. High-volume kitchens saturate media faster and need more frequent replacement. Your Authority Having Jurisdiction (AHJ) may require a stricter cadence.

High-Volume Operations

  • Charbroiling, wok cooking, 24-hour kitchens
  • Containment media replaced quarterly or more frequently
  • Rooftop grease cleanup at every service visit

Moderate & Low-Volume Operations

  • Full-service restaurants, churches, seasonal kitchens
  • Containment media replaced semi-annually or annually
  • Condition checked at every exhaust cleaning visit

FAQ

Rooftop Grease Containment Questions

Why does rooftop grease containment matter for my roof?
Exhaust fans discharge grease-laden air onto your roof. Without containment, that grease pools around the fan base, saturates the roof membrane, and causes permanent damage — staining, softening, and eventually leaks. Grease damage is typically excluded from roof warranties and can void your coverage entirely. Containment catches the grease at the source before it reaches the membrane, protecting your roof investment and keeping your property compliant.
How often does the containment media need to be replaced?
Replacement frequency depends on your cooking volume and grease output. High-volume operations (charbroiling, wok, 24-hour kitchens) may need replacement quarterly or even monthly. Moderate-volume restaurants typically replace media semi-annually. We check containment condition on every scheduled exhaust cleaning visit and replace media before it becomes saturated. We recommend coordinating replacement with your NFPA 96 cleaning schedule.
My landlord requires grease containment — what do I need?
Most commercial leases require tenants to prevent grease damage to the roof. We install containment systems (pads, pillows, or corrals depending on your fan type and roof layout) that catch grease discharge at the fan base. We provide photo-documented installation reports and ongoing replacement records that satisfy landlord requirements and demonstrate you are maintaining the system. If your lease specifies a particular system, we can match it.
Does rooftop grease containment relate to NFPA 96 compliance?
NFPA 96 requires that grease discharge from exhaust systems be managed and not allowed to create a hazard. Uncontained grease on a rooftop is a slip hazard, a fire risk (grease-saturated roofing materials), and an environmental concern. While NFPA 96 does not prescribe a specific containment product, fire marshals and inspectors routinely expect to see containment in place as part of a compliant exhaust system. Having it installed demonstrates responsible maintenance.
