How to get realistic reflections on buildings

So I am working on this scene of a fly-thru in a city.

When I look at real life references, I can see irregularities in the windows of buildings gives a very interesting reflection of the environment.

However, in CG most buildings are modeled perfectly, where all the window panels are perfectly flat which gives you a perfect reflection as well.

So my question is how do I achieve this imperfection of the reflection? So I add a bump to the model? or It will be crazy for me to tweak the model randomly in this massive scene.

Thanks for the help guys!

This.

Apply a very large noise to your bump and adjust the uv coordinates for each window a bit so it's not just one big map for all wndows but a bit of variation.
