Question to experienced RE investors

[Allen Lucas]

I own one house in a regrowing market in MD. I have owned this property for 4 years and started living here almost 2 years ago. I bought the house with about $50,000 in equity but since then I have had tenant issues and almost lost my house to foreclosure but ended up working things out with the bank and remodifying my loan. Since then I have done a ton of work in here and although the market is going up, my contractor is telling me that I need to fix the roof(which is in fair condition) before I sell the house. But I'm ready to put it up now "as is." I bought the house for $125k. Back then it appraised for $170k. I have gotten a few rough estimates and the house is now valued approximately at $220k but the modification bumped my loan up to $136k.i have already spent about $25k in home improvements. Should I fix the roof? Would not fixing it be a huge blow to the profit?
