Improving roof insulation on old flat roof home

I own an old (1949) NDG home and recently replaced the roof due to a leak. While in the crawlspace below the roof I noticed that the insulation is very thin in places and there are mouse droppings and other debris. My plan is to replace the insulation or cover it this fall with new insulation - to improve the r factor as much as possible, but I've heard that these old houses need to breathe so I'm wondering what the best approach is. Do I replace, cover over, use sheets or spray? What type of insulation would be best - pink, foam or something else? Are there specific things to consider or avoid?

Thanks in advance.
