Can't stress how important roof safety is for us... Many owner-operators are exempt from this "rule" as far as fines are concerned. However, safety doesn't affect just yourself.

Your wife, kids, employees, other family, even your entire industry can affected by a fall.

If you are an owner-operator and don't wear a harness - STOP! No roof cleaning is worth your life. 

Side benefit - installing roof anchors is a great upsell and add-on service. Especially when you have to do it anyway. We taught all our guys to install them.
