RCIA's very own Bill Booz will be teaching a class on roof safety at the NCE, Pressurewashing Institute event in Charleston, SC September 28 and 29th 2010. I am loading him up with lots of safety equipment we invented over the years and such. Its going to be an awesome class. He doesnt teach repeling though. In 20 years of roof cleaning we never had to repel. However you can usually contact your local fire rescue and one of the fire fighters will come out on thier own time for a buck and totally set you up!
