Are kickout flashings required by code?

Wednesday, March 18, 2020

A kickoff flashing, also called a diverter flashing, is required by the International Residential Code (IRC R093.2.1). It is installed at the termination of a roof-to-wall flashing where it meets the eave and shifts the direction of the water flowing down the roof to move it away from the end of the wall.
