We have thermoplastic polyolefin (TPO) roofing systems and I am concerned about the chemicals our HVAC contractors use to clean coils in the rooftop units. While doing a roof walk last week I noticed the cleaner running down the roof, and I am wondering if the cleaner being used might cause damage to the roof. The product being used is ACE Foam-N-Clean Coil Cleaner. Is this product safe for extensive contact with TPO roofs?
