A roof penetration is a hole or opening in a roof that is made to accommodate pipes, vents, or other objects that pass through the roof. These penetrations can be a potential source of leaks and other damage if not properly sealed and maintained. In general, a roof penetration is any opening in the roof that breaks the continuity of the roofing material and allows water or other elements to enter the building. Residential roofing penetrations can include things like skylights, ventilation systems, chimneys, and any other type of equipment or feature that penetrates the roof. Other common types of roofing penetration include plumbing vents, HVAC units, and satellite dishes. These penetrations can be sealed to prevent leaks and other damage to the roof.
