Description
Apron flashing is the metal that covers the transition between a roof slope and a roof penetration such as a dormer or chimney. Properly installed this flashing will protect the most vulnerable areas of a roofing system. Apron flashing is usually applied as part of a two piece roofing system. The apron is the lower L-shaped piece that covers the roofing material and extends up the vertical surface of the roof penetration. The second part of the system is a counter flashing that extends from the vertical surface and covers the vertical leg of the apron.
