Openings in the Horizontal Seams
The fabrication of metal roof panels that cover the whole structure’s rafter length is tough, and periodically difficult. The length of the panels might be limited in some styles by the project designer due to growth and contraction.
Due to the limitation on panel length, the roof system should have horizontal joints set up by the installer. The standing seams in the metal roof are perpendicular to these horizontal joints.
In time, horizontal joints are prone to separation. This may make a hole in hydrostatic metal roof systems, allowing water to seep back into the structure.
Openings in Penetration Flashing
Growth and contraction prevail with metal roof systems. This is the effect of temperature level variations causing the metal panels to move. Tension is caused by this movement at the roof system’s penetrations and points of connection. The tension triggers the flashings at the penetrations to break down, which causes roof leakages at skylight and vent penetrations.
