Commercial flat roofs are designed to withstand years of exposure to the elements, but one of the biggest risks to an EPDM rubber roof often comes from people working on top of it. Heating and cooling technicians regularly access rooftops to service HVAC equipment, and while their focus is understandably on the mechanical systems, accidental roof damage can occur during routine maintenance. At The Flat Roof Guys, we’ve repaired many EPDM roofs throughout Northeastern Pennsylvania where the leak wasn’t caused by weather at all—it started with foot traffic or misplaced equipment during HVAC service.
Unlike shingles, EPDM rubber roofing relies on a continuous waterproof membrane. It is extremely durable and can last 30 to 40 years when properly installed and maintained. However, sharp tools, dragging heavy equipment, or repeated traffic in the same locations can create punctures, abrasions, or stress on seams that may not become obvious until the next heavy rain.
One common issue occurs when technicians move ladders, toolboxes, or replacement parts across the roof. Small screws, sheet metal scraps, or sharp corners can nick the membrane without anyone realizing it. Even a tiny puncture can allow water to work beneath the roofing system over time, leading to insulation damage and interior leaks.
Another problem involves rooftop HVAC units themselves. Service personnel may temporarily place equipment directly on the membrane instead of using protective pads. Compressing the rubber with heavy objects or dragging them across the surface can wear away the membrane or damage flashing around rooftop penetrations.
Repeated foot traffic is another concern. Every roof has designated walk paths or areas that receive more use than others. Without walkway pads, years of technicians walking the same routes can gradually wear the membrane’s protective surface. While EPDM is highly resilient, concentrated wear eventually increases the likelihood of leaks.
Loose access panels, dropped fasteners, and forgotten tools can also create future problems. A single screw left on the roof may not seem significant, but after months of expansion, contraction, and foot traffic, it can work its way into the membrane.
Building owners should schedule periodic roof inspections, especially after major HVAC repairs or equipment replacements. Catching minor damage early is far less expensive than waiting until water enters the building and damages insulation, ceilings, inventory, or electrical systems.
Coordination between roofing contractors and HVAC companies is also beneficial. Experienced technicians appreciate knowing where sensitive roof details, seams, and flashing are located before beginning work. Simple precautions like using protective walk pads, lifting equipment instead of dragging it, and cleaning up debris before leaving the roof can dramatically reduce the chance of accidental damage.
At The Flat Roof Guys, we specialize in inspecting, repairing, and maintaining EPDM rubber roofing systems throughout Wilkes-Barre, Scranton, Hazleton, Bloomsburg, and surrounding Northeastern Pennsylvania communities. If your building has recently had rooftop HVAC work performed, or you’ve noticed a new leak after equipment servicing, it’s worth having your roof professionally evaluated before a small puncture becomes a costly repair.
