Importance of Roof Drip Edge Flashing

Building code requires roof drip edge flashing on steep slope roofing. Roof edge flashing protects the edges of the roof sheathing from water damage. Without this flashing the roof sheathing is susceptible to rot and deterioration. The flashing at the eave edge also helps direct water to flow into the gutter. The roof edge flashing will protect the roof structure from costly repairs.

Roofs installed before 2012 might have been installed without using roof edge flashing. Building code did not require this flashing prior to 2012. Quality roofing contractors were already installing roof edge flashing before it had become a requirement. Unfortunately, there are still many roofing contractors that do not install roof edge flashing. This is an item that can also be overlooked by a building inspector. Due to safety constraints placed on building officials, the building inspector generally cannot access the roof. Therefore, some items that should be checked by the inspector may go undetected. The roof edge flashing on the gable ends can be spotted from the ground. However, the eave edge flashing may not be visible if the gutter has already been installed.

A roof edge flashing should have a 3/8″ to 1/2″ kick out at the end of the flashing. The kick out is also known as a drip edge. This kick out will prevent a capillary action that will keep water from traveling up behind the flashing. The roof edge flashing should be a minimum 26-gauge galvanized sheet metal that has a powder coated paint finish to protect it from corrosion.

Be sure to make sure the roofing contractor you choose is installing the required roof drip edge flashing. This flashing will help protect your investment safe from the weather elements.
