Pole plate - remove rendering or not?

[Roberto2019]

The pole plate (I think it is called that - I.e. the wall plate attached to the existing house on a lean to roof) - must you remove all the rendering before attaching it, or can you leave it and screw directly into the rendered brick... providing the render is sound of course.

It is a right pain to remove!

You could leave it as long as you use longer fixings to fix deep enough into the brick.

You should remove render for any flashings
