Grease Containment
Protecting the roof from kitchen exhaust grease is essential for fire safety, roof longevity, and clean stormwater practices. This category brings together containment systems designed for rooftop exhaust terminations.
Use this page to understand common system types, key sizing checks, and maintenance planning so you can choose a solution that fits your fan, menu, and service interval—without restricting fan performance.

Grease Containment FAQ's
What information helps size a system quickly?
Share fan make/model, duct size, roof slope/curb details, proximity to intakes or combustibles, menu type, and service frequency goals.
Do I still need a hinge kit if I install containment?
Yes. Containment does not replace safe fan access. Hinge kits and secure electrical disconnects help crews clean the fan and change media safely.
Can I drain captured grease to the roof or storm drain?
No. Prevent runoff to roof drains and manage saturated media or liquid collection in accordance with local disposal rules to avoid environmental violations.
What’s the benefit of listed grease containment hardware?
Listed systems are tested to applicable standards and are often preferred by AHJs. They help demonstrate that grease is collected without compromising fan operation.
How often should absorbent pads or media be changed?
Set intervals by inspection. Start with short checks, document actual accumulation, and adjust the schedule to your menu, hours, and seasons.
Will grease containment reduce my fan’s airflow?
A correctly sized, compatible system should not restrict airflow. Avoid makeshift trays or media that block discharge paths, and follow the product’s installation guidance.
Do I need rooftop grease containment on my exhaust fan?
Most AHJs adopt NFPA 96 or similar codes that expect rooftop terminations to include a grease collection method that does not inhibit fan performance. Check your local code or ask your AHJ.
