Costs for urgent roof repairs! Missing a little & it’s really urgent.

How to even say this in short. I've got in trouble this time and i finally accepted that i can not do it all on my own.

It's really a long story so ill try to keep it short. Around 4 years ago we moved to a house on my fathers wish and we were determined to make it a really nice place. As time passed by father got cancer on pancreas and sadly passed away a bit more then a year ago. Since then i'm giving my best to keep things together. All that i have left of my family is my grand mother which is also quite ill. I'm doing this more for her than me.
The situation is bad, one side of the roof is good, i managed to repair it. The other one is a tricky one and its already leaking water in it is and falling apart. I found good people to do the job but naturally every one needs to get their payment, it's their job for a living. I have some money on side which i have been collecting, but to be only one single person against it all, it became impossible. I assume this is the amount that would save my life. So i call out all of the good people that understand my situation and have compassion for someone in need.
If you can, please help me!
