One of the best parts of our job at Seamless Roofing is working with property owners to inspect their roofs and educate them about what’s really going on. During a recent inspection, our team was only scheduled to review the older parts of a commercial roof. But as any experienced roofer knows, you never know where a problem might pop up.
While walking the roof, we found a small but persistent leak in a section that wasn’t part of the older material. It was subtle—hardly noticeable at first glance—but the implications were significant.
This small leak proved to be a classic example of how overlooked details from other contractors can cause severe damage.
The Culprit: An "Install and Forget It" Mistake
After a closer look, the source of the leak became clear. A piece of electrical conduit was resting directly on the roof’s surface without any proper support. According to our findings, this kind of oversight is surprisingly common and highly destructive.
Unsupported rooftop equipment, like conduit, gas lines, or HVAC components, can quickly become a problem:
- Abrasion – Roof membranes expand and contract with temperature changes. An unsupported line repeatedly rubs against the surface, similar to sandpaper. This friction can create a small hole in the membrane, leading to leaks.
- Debris dams – The conduit also collects water, leaves, and dirt, forming a permanent ponding spot. Constant exposure to moisture accelerates membrane deterioration and can cause additional structural issues.
Even a small gap left unaddressed can trigger a chain reaction of damage to the roof's long-term health.
The Real Lesson: Your Roof vs. Other Contractors
Most tradespeople—electricians, plumbers, HVAC technicians—concentrate on doing their work efficiently. Their main focus is on functionality, not on the structural integrity of the roof beneath their installation. A roofer’s perspective becomes essential here.
As Eric Howland, Partner – Operations, emphasizes in a recent LinkedIn post, it’s crucial to inspect your roof to make sure gas lines, conduit, and other rooftop accessories are installed, taking roof wear and tear into account.
Correct installation looks like the following:
- Components are elevated on proper supports or "sleepers" that allow water to flow freely underneath.
- Lines do not make direct contact with the membrane, preventing abrasive wear.
- Installations are arranged to minimize debris accumulation and ponding.
- Routine inspections verify that supports remain in place and no movement has compromised the system.
By following these steps, small oversights can be prevented from turning into serious structural or water-damage problems.
Preventing Costly Roof Damage: The Importance of Professional Assessments
That "tiny leak" we discovered was more than just an inconvenience—it was a warning. A minor, often-overlooked detail that, if ignored, could grow into an expensive repair project, threatening the roof’s lifespan and the building’s overall integrity.
For property owners who have had other trades work on their rooftops, a professional inspection is crucial. Even minor, seemingly insignificant issues can cause long-term damage.

We identify the root causes, including those caused by other contractors, and provide solutions to protect your roof for years.
