Rooftop Grease Containment

If your restaurant follows the standards set by the National Fire Protection Association, your kitchen will have a rooftop grease containment  system. This is the storage compartment of grease that your kitchen hood vacuums up. It demands professional restaurant cleaning services to ensure the safety of your staff and customers.

The kitchen exhaust system traps dirt and grease present in the atmosphere to keep your kitchen clean. This grime then goes up to the rooftop which is generally made of rubber. The benefit of rubber rooftops is that they will expand and contract according to the weather, making them durable.

What is the need for a rooftop grease containment system?

A functional rooftop grease containment system entraps the grease coming from the hood and protects it from overflowing. However, if it is not correctly working, the grease will overflow onto the rubber roof. 

The acidic nature of the grease will then react with the rubber, making it hard. This can lead to cracks and permanent roof damage. This excess grease can also flow down through the sides of the walls, leaving permanent stains. The grease will be able to flow through the drainage during rains and block that system as well. And in the worst-case scenarios, it can start a fire inside the drainage system.

The only way to avoid this is by ensuring that your rooftop grease containment system is in good condition.

Get the Right Rooftop Grease Containment

Get the right rooftop grease containment systems for your kitchen to keep the rooftop safe from grease leaks. Grease containment systems have a hydrophobic lining that keeps the water away from grease. So, even during a heavy rainstorm, the grease deposition won’t mix with water.


It’s good to get grease contaminants for each hood system in your kitchen. This will prevent the over-deposition of grease to one containment system. This way, you can be assured that your exhaust system is safe. 


Rooftop grease containment systems are available in different sizes and shapes; you should choose one according to your kitchen’s requirements. Consider factors like the size of the kitchen and the amount of grease deposition on the hood.


You should also check the guidelines of the health department in St. Louis, MO, before installing the containment system. As per their suggestions, you should hire a professional to install a grease containment system over your rooftop.

How to keep your rooftop grease containment system in good condition


Once a grease containment system has been installed, the next step is to keep it clean. Grease containment is a temporary storage area for the grime and grease of your kitchen. To keep it safe from leakage, you must clean the entire hood system regularly.


Any amount of grease stuck on the hood system for long can result in fire. It includes the rooftop containment too, where the largest amount of grease will be present. So, it is essential to ensure the maintenance and cleanliness of the tank.
