A flashing is
a barrier, usually aluminum, copper, galvanized steel or an
asphalt based membrane, or roll roofing that seals the
joint(s) when a roof plane is interrupted (skylights, vent
pipes, chimney, side wall, etc.) or altered (valleys,
gables, etc.). The flashing is designed to divert water away
from the joint to prevent interior water penetration.

Considerations
The HouseMaster Technical Staff notes that most roof leaks
are not the result of worn roofing materials; rather most
are caused by missing or defective flashings. There are many
types and styles of flashing available depending on the roof
style. They all have one thing in common – the requirement
for constant monitoring and periodic maintenance. If
installed improperly, or as a result of normal aging,
flashing will eventually dry out, separate, tear, or
otherwise fail and no longer provide a watertight seal.
