Why Is My HVAC Unit Damaging the Roof Underneath It?

Your rooftop HVAC unit may be doing its job keeping the building cool, but underneath it, your roof membrane could be taking a beating. And no, the HVAC unit isn't angry—it’s just heavy, hot, and constantly vibrating. Unfortunately, your roof doesn't exactly enjoy that combination.

During the hot summer months, the roof membrane can heat up and become more vulnerable. Add an HVAC condenser sitting directly on it and vibrating all day, and you've got a recipe for tears, holes, and potential roof leaks. Basically, your HVAC unit is doing a tiny dance routine on your roof, and the membrane is getting stepped on.

A sacrificial membrane was installed underneath the HVAC condenser to act as a protective layer between the equipment and the existing roof membrane. Rubber pads can also provide protection by creating a buffer that helps reduce direct contact and wear.

Imagine of it like putting a phone case on your phone. The HVAC unit still does its job, but now the roof has some protection underneath it instead of taking all the abuse directly.
A small protective upgrade today can help prevent a much bigger flat roof repair tomorrow.
