A wall cladding crew starts above a low roof before the base flashing and counterflashing are installed. Water will shed from the wall onto that roof edge. What is the best correction?
Correct Answer
A) Stop and install the flashing sequence so water is shingled to the exterior drainage path
Flashing must be sequenced shingle-fashion so water drains outward rather than behind the roof edge. Other choices use non-durable sealant, rely on evaporation, or delay a concealed critical layer.
