So sorry to hear this. Ladders can be extremely dangerous.
I was just out yesterday with my 30-year old son who had me hold the ladder while he climbed up and checked on the roof. He wouldn’t go up or come down until he knew I was holding the ladder in place.
Green Bay Packers receiver Max McGee died after falling from the roof of his house trying to clear leaves. His wife had warned him not to climb up there. He was 75 years old.

That is standard practice for ladders. Always have a spot.
