Installing 90-degree metal angle flashing can be done easily by attaching it to the outside of your siding.
Angle Flashing
Deck flashing should extend at least two inches up the siding. This complimentary color blends well with the stained siding.

Fiber Cement Flashing
Use caulk along the top edge of the metal flashing to ensure that moisture doesn't get behind it.
