Why Is My HVAC Condenser Base Cutting Through My Roofing Membrane and Causing Damage?

If your HVAC condenser is sitting directly on the roofing membrane, it can gradually wear down and damage the surface beneath it. Over time, you may start to notice signs that the condenser base is cutting into the roofing membrane, especially if there is no protective barrier in place.

This issue becomes more noticeable during the summer months. As the roofing membrane heats up, it softens, and when the condenser is actively running, it creates vibration and movement. That constant motion, combined with the softened surface, can cause the condenser base to press into the membrane, eventually leading to tears, punctures, and even leaks. If left unaddressed, this type of damage can worsen and compromise the integrity of your roof.

If the condensers are sitting directly on the roofing membrane without proper protection, these warning signs should not be ignored. What may start as minor wear can quickly turn into costly repairs.

At Anchor Point Roofing, we address this issue by installing a sacrificial membrane beneath the condensers. This added protective layer helps absorb movement, reduce friction, and prevent direct contact between the condenser base and the roofing membrane. It’s a simple but effective solution that helps extend the life of your roof.
