Evaluating the Cause of Grease Build Up on Your Roof Top

There is a common misunderstanding between kitchen exhaust cleaning service providers and facility managers regarding grease build up on their roof tops. Most restaurant or Facility Managers feel that if there is grease on their roof top then there must be a deficiency in the work being performed by their service provider. Often this can be the case.

The first way that grease can accumulate on the roof top is through poor waste water management during the cleaning process. This is the easiest of the three to evaluate, though it does require follow up by the restaurant staff. During the cleaning process there are a few ways that grease can accumulate on the roof top.

By doing this, the blades spin and grease and water are slung out of the fan on to wall, roof top, A/C units, etc. This can cause multiple problems but typically can be detected easily....
