Roof Flashings are strips of flexible metal or roofing felt that keep water from penetrating the joint between the roof covering and other roof components.
Flashings are the Achilles heel of most commercial roof problems. Whether it’s the insulation that’s wet, or the field of the roof that’s leaking, there’s a great chance that the flashings are the original point of entry. It is estimated that over 75 percent off all low-slope and flat roof failures begin at the flashings. Why? Flashings have greater exposure to weather, and will begin to deteriorate before the roof surface shows any indication of disrepair.
Additional Reasons why Flashings are particularly vulnerable
Flashings terminate the roof membrane. The angle of the membrane changes at the flashing, causing strain at the weakest point.
Flashings are also vulnerable to physical damage since they are situated over the side where work it frequently done.
Flashings are frequently composed of saturated paper that readily absorbs water.
