Help Grandpa Rebuild after IRMA

Many people in South Florida are dealing with a mountain of debris on their lawns following Hurricane Irma, but one my grand father in Miami is dealing with much worse.
His neighbor's tree came crashing down on his home during the hurricane, and three weeks later, it still hasn't moved. My Grandfather was forced out of his home after the tree came crashing into his bedroom.
He said he does not have insurance. We have applied for FEMA but they have not provided any help for him yet. 
Anything you can donate is appreciated.
