Home improvement

I am looking for a grant to get a new roof for my home. I am a 67 year old contractor for a prescrition glasses company my husband is blind in his right eye from a stroke and he has bladder and prostrate cancer, He is also on dialysis for end stage renal failure. We have a leaky roof due to the last texas hurricane Nicholas. My roof is old and the wind from the storm caused leaking around the chimney so I have ceiling damage due to rain.
