Wrong kit for the tile type, missing lead soakers on plain tile roofs, and degraded EPDM weatherseal gaskets are the three most common causes.

The diagnostic process: identify the unit model and flashing kit specification, inspect the flashing perimeter from inside through the open window, assess lead soaker provision on plain tile roofs, and check drainage channels at the frame base.
