All commercial roofs have some sort of various piping, signs, HVAC units, electrical conduit or roof vents needed to make the building functional for their intended purpose. Most of these need to be routed from the interior through to the exterior, resulting in a mechanical roof penetration. Some commercial roofs may have more penetrations than others, but the fact still remains, all penetrations can be a source of leaks if not installed and maintained properly.
