Repairing My mother’s roof

I am the son of a 62-year old Eldery woman who lives with her in order to help her with medical and other areas of life. She moved from Texas back in 1995 to allow her mother (grandmother) top be with her son. Both have since passed on as well as her husband (my dad) and she hs incurred various alimentsm with time. Eventually she was diagnosed with Colon Cancer last year and had surgery to remove it and went through chemotherapy the first part of the year in order to make sure it did not spread to other areas. She was diagnosed years ago with COPD with emphysema and also irregualr heartbeat as wellas beinga diabetic for nearly 30 years. We have been struggling like everyone else but have been fortunate to pay our bulls had have food our table despite having most my job almost 6 months ago. However, the roof on her house is deteroriating severly. We have been tarping over it for the last couple of years through the winter and into the spring. Usually by late summer early fall though, the tarp, due to normal weather wear and tear, wears through. Our credit from past issues is very poor. Therefore, we have decided to ask for donations to have it repaired by the spring at the latest.  I am hoping we can have an acquaintance tarp over it for the winter and get to working on it in the spring if we can gain the funding for it. It can become a serious issue for her health if it gets worse. So please help us repair our roof.  It is two different heights on one side is why it seems a little higher than it should (at least that is what I have been told by two different amd reliable people.) Feel free to ask any questions if you wis, I will answer them as best as possible.
