Need Advice on Repairing Aluminum Roof Over Bay Window
 

We had a storm blow through last summer and it (I think) pulled part of
the edge of the aluminum roof over our bay window away from the fascia
board. The length of the edge in question is about six inches. The
remaining edging is still adhered to the fascia board. How can I
repair the edging that has been pulled away? I think when we have
wind-driven rain, the rain is blown above our ceiling in the kitchen
which eventually leaks through a light fixture.
