Over time, horizontal joints are prone to separation. This might make a hole in hydrostatic metal roof systems, enabling water to leak back into the structure.
Openings in Penetration Flashing
Expansion and contraction are common with metal roof systems. This is the impact of temperature variations causing the metal panels to move. Stress is caused by this movement at the roof system’s penetrations and points of connection.
