What is Step Flashing?
Roofing Glossary · Installation
Definition
Individual rectangular pieces of metal flashing installed in an alternating staircase pattern at the junction of a vertical wall or chimney and the sloping roof surface. Each piece of step flashing is installed with one tab under a shingle course and one tab turned up against the wall. Step flashing is the building industry standard for wall-to-roof transitions and provides superior waterproofing compared to continuous or apron flashing alone.
