Sacrificial Membrane Under HVAC Units for Commercial Flat Roofs in Chicago

On many commercial flat roofs in Chicago, HVAC units are installed directly on the roofing surface. Over time, the constant vibration and movement from this equipment can wear down the roof membrane, leading to punctures and potential leaks. To prevent this, commercial roofing systems often use a sacrificial or loose membrane under the HVAC units.

This additional layer serves as a protective barrier, taking the brunt of the wear and tear so that the main roof membrane remains intact. By installing a sacrificial membrane, property owners can extend the lifespan of their roofing system and reduce the risk of costly water intrusion.

At Anchor Point Roofing, we provide expert commercial roofing solutions throughout Chicago, including protective measures like sacrificial membranes under rooftop HVAC systems. Our goal is to help building owners protect their investments while maintaining watertight and durable flat roof systems.
