Recently, we had a contractor using our on-line snow retention calculator ask this question. He had done a number of planning calculations to customize applications of our ColorGard® system for a particular project, and noticed the field for “Safety Factor” on our load information table and also the calculator. What is this? And what does it do? He wanted to know.
Why is it a bad idea to put snow guards just over doorways?
Often, we are asked to provide localized snow guards and systems (snow retention systems) over an entranceway or several of them rather than protecting the entire eave line of a standing seam metal roof. In limited cases this can be done, but extreme caution is advised.
