What term applies to any object that passes through the roof?

The term that applies to any object that passes through the roof is "penetration." In roofing terminology, penetrations refer to any openings created in the roofing system to accommodate items such as plumbing vents, exhaust fans, skylights, or HVAC equipment. These penetrations are critical points in the roofing system that require careful attention during installation to ensure that they are properly sealed and waterproofed, thus preventing leaks and other potential issues.

Understanding penetrations is essential for roofers as they must ensure that each penetration is designed and constructed to minimize the risk of water intrusion. This concept is fundamental in roofing and is a key factor in maintaining the integrity of the roofing system.
