Neighbor has hole in roof from Irma & slumlord doesn't care

[Virginia B.]

My poor neighbor has a really crappy landlord and I'd like to help her but I have no idea where to start. She has had one hole in her ceiling for months and now has a hole from a tree coming through into her bedroom. The landlord won't return her calls for months now (she major septic issues and had to pay out of pocket, amongst other things), has blocked her daughter on fb & she doesn't know what to do. I have the landlords address & want to give him a piece of my mind, but I know that isn't going to solve anything.. Where does she start? Other details - no lease, verbal agreement. In GA, Gwinnett county. She says has been paying on time every month. Thanks all. I can't wait to be a solid landlord.
