If you look closely you will see edge of roof open. This is due to incorrect flashing application or lack of. Metal flashing should be installed on top of roof membrane and then flashed with roof material. This is one of the # 1 details that are often installed incorrectly. Resulting in water seepage which often time causes wood rot and or mold. These type of leaks often go unnoticed because are very slow and minimum and often times do not show on drywall or plaster of the walls.
