Flashing Between Siding And Brick
The metal flashing placed on wall top slopes back towards the building directing water inside the structure.
Flashing between siding and brick. You need to make sure each material sheds water over the top of the material below without getting behind or under the materials. In your case there is a great need for a flashing that runs along the top of any of the horizontal fascia boards. Maybe in this case the flashing extends upwards behind the building siding forming a zee shape that might reduce this risk. Flashing between brick and siding is a relatively similar process on all types of brick to siding transitions although there may be slight variations based on manufacturer recommendations.
Transition from brick to siding. Yes the proper detail is to fur out the siding over the face of the brick with at least a 4 overlap. It might be buried behind the siding where you can t see it. Details like this risk rot and insect damage to the structure.
Using a metal j flashing between these types of transitions provides a barrier between siding and transitions that protects against water intrusion. Each time you transition between materials say foundation siding brick windows doors etc.
