Henderson Retires

After 39+ years in the business, Darrel Henderson has decided to hang up his clipboard and semi-retire. He must have roofing in his DNA, as his ancestors installed slate roofs in England back in the 1800’s. He was on the Ontario Chapter Membership Committee in 1997 and was the secretary from 2000-2001. He has lectured for RCI from 2002 until the present day, and he was involved in the creation, along with John Kataila, of the Fire-rated Roof Module for the Building Science Specialist of Ontario (BSSO) Program at the University of Toronto.

Henderson was introduced to roofing by Bruce Russell at Tremco in 1978, and to roof consulting by Doug Fishburn. He still issues the URL lists that began in 1999 and 2006 to his contacts in the industry. He can be contacted at
