When flashing fails, the roof can start leaking even if the main surface still looks acceptable.
What flashing actually does
Flashing directs water away from vulnerable transitions and helps the roofing system stay watertight where different surfaces meet.
It is less visible than shingles or panels, but it often does just as much of the waterproofing work.
Where flashing problems usually show up
Common trouble spots include chimneys, skylights, wall transitions, valleys, roof edges, and penetrations such as vents or rooftop equipment.
When one of these areas weakens, the leak can show up far from the original entry point.

Why flashing deserves attention during repair and replacement
Many roof problems are not caused by the field material alone. That is why flashing review is built into our roof repair and roof replacement work.
The visible roofing surface and the flashing details have to perform together.
