Rooftop Grease Containment Portland


80% of the deterioration of a roof over a commercial kitchen is due to grease coming out of the exhaust fan.

A commercial kitchen exhaust fan is designed to trap the grease and other particles that are floating in the air.  They have to go somewhere and that’s to the roof top.  

Most roofs are made from rubber.  This allows the roof top to expand and contract without damage to the roof top due to hot or cold weather.  A rooftop grease containment system is designed to keep the grease from overflowing onto the roof.  If the grease does spill over in as little as two weeks it can cause damage to the roof and a hood cleaning won’t be enough to save it.  Grease is acidic, so when it accumulates onto the roof top it deteriorates the rubber which will get hard and start to crack.  

This can cause severe harm to the roof costing thousands of dollars to fix.  The other issue is an environmental one.  If the grease is flowing onto the roof and then a rainstorm happens in Portland, the grease can run off the roof with the water down the side of your structure which can cause a stain.  It will also take the natural path to the drain storm.  Not only does the grease block sewer systems, it can lead to sewer fires and contamination to water supplies.  If it is proved the grease came from your restaurant the fines and cleanup could cost thousands of dollars.

What is a rooftop grease containment system in Portland?

A rooftop grease containment system is designed to capture the grease that is sucked up through your exhaust system The National Fire Protection Association fire Code 96 actually requires all commercial kitchens to have one installed.  

These containment systems come in many sizes and shapes, so it is best to discuss your needs with a company that understands your equipment and your needs in Portland.  They are designed to trap the grease and prevent it from  overflowing on to your roof where, as mentioned above, grease on your roof is not only a fire hazard, it can also damage the rooftop itself.

Rooftop grease containment systems have hydrophobic pads that are designed to shed water keeping the grease restricted.  If you just had a grease box, the rain would mix with the grease and an overflow can happen.  

Grease is very acidic, and it can start to eat away at the rooftop material almost immediately.  This could lead to costly repairs if not caught soon enough.
