One of the world's richest men who made billions with a roofing company has died after falling through the garage roof at his home.
Ken Hendricks, 66, was checking on construction of the roof at his house in Illinois when the accident happened. He suffered massive head injuries.
Mr Hendricks, the 91st richest person in America, was the founder, chairman and chief executive officer of ABC Supply, a wholesale distributor of roofing materials.
He had a net worth of $3.5 billion, according to Forbes magazine's listing this year. But he seemed unaffected by his wealth.
"It doesn't make any difference to me; I can't spend it," he said in an interview with in September 2006. "I'd have to sell the company, and I'll sell the company over my dead body."
Mr Hendricks, the son of a roofer, worked side-by-side with his father growing up. A high school dropout, he started his own roofing business at 21.
Tired of having to deal with multiple suppliers scattered around the country, he and his wife, Diane, started a national supply distribution chain in 1982.
