At 17, Ken Duval literally had no roof over his head. But thanks to risk-taking on an unwanted property, the sacrifice of a place on an Olympic-bound team and a lot of determination, Ken has developed an industry-leading small business in North Reading, Mass.

Duval Roofing now stands out as the only roofing contractor in the area with its own waste transfer station, and Ken employs a tight-knit team of roofers with such great organization and leadership that they finish installing most new roofs in an astonishing 8-hour day.
