Protecting Roof Integrity with a Grease Containment System

Project Spotlight: Protecting Roof Integrity with a Grease Containment System

At Cotterman & Company Inc., we recently helped a customer prevent costly damage to their TPO roofing system by addressing a common issue for restaurant rooftops: grease accumulation from exhaust systems. Grease can be particularly harmful to TPO membranes, compromising their durability and potentially voiding manufacturer warranties.

Our team tackled this by using an approved cleaning method to safely remove existing grease from the membrane. We then designed and installed a rooftop grease containment pad at the vent curb, ensuring future grease discharge is contained and diverted away from the roof surface.

The result? A safeguarded TPO membrane, a protected warranty, and peace of mind for our client!

Protecting your roof’s integrity while maintaining manufacturer warranties is what we do best. If you’re facing similar challenges or want to proactively prevent them, don’t hesitate to reach out.

Last week, after the snow and ice finally cleared here in Dayton, Cotterman & Company Inc. completed a roof evaluation on a large warehouse facility that had recently started experiencing leaks. As part of the inspection, a date stamp was located on the membrane: DL ’99. That simple marking told a big story.

After severe storms rolled through the area, our Service Department was called to a local hospital to investigate new roof leaks. Cotterman & Company responded quickly and delivered solutions that protected critical facilities with no shutdowns, no delays, and no compromises.
