DEAR BOB: My father, age 78, lives in his home alone. He has become a bit senile, but he can still be very feisty. His house badly needs a new roof. But he stubbornly refuses to have one installed because he says he can't afford it. Every time there is a heavy rain, he complains about the leaks and why he can't find a roofer to patch the leaks.
