Best shader type for brick buildings

I've searched around and can't find a decent discussion/answer to what type (and settings) of shader to use (assuming Unity's own shaders) for a brick buildings (RTS orthograpic camera view). Right now I'm using the Standard Shader (Roughness) with Roughness turned up to 1. It's quite good but from certain angles it still looks as though there's this bit of shiny reflection (I turned off Specular Reflection).

Anyone have experience with (outdoor view) buildings and how to best use shaders?

Big thanks in advance for any advice.
