Due to the harmful effects of grease and oil on all roofing systems, most major roofing manufacturers will recommend or specify a UL listed grease containment system for areas that will be exposed to grease and oil. The damaging effects to the roof shorten its life and increase the likelihood for premature roof repairs and replacements, costing building owners thousands of dollars. 

When obtaining a warranty for a building that has known grease and oil problems, it is standard operating procedure to submit information on the grease containment system to the Technical Services Department of the roofing Manufacturer.  In addition, approval must be obtained for your warranty at the time of the re-roof or the new roofing system.  Most roofing manufacturers will not extend a blanket authorization; they will give approvals on a site-specific nature. 

Facilitec recommends that you talk to the Technical Services Department of your Roofing Manufacturer to make sure you are covered with the proper grease containment system for your needs.
