Flashing
Material arranged at joints, penetrations, and transitions to collect or direct water away from vulnerable construction.
Why it matters
Continuity and termination details matter. A new roof or facade can still leak where its interfaces with adjacent work were not properly addressed.
In practice
A project example
A roof replacement needs coordinated flashing at a parapet rather than simply a new field membrane.
