What is the best system of snow fences or snow guards?
I tried to get something to stop snow slide on metal roofs and met with snow fences and snow guards. Anyone have any experience using these two?
Typically, a system of snow fences will be the performance of a system of snow fence. The reason is that the guardians of the snow are arranged in rows that keeps snow and drag to drift. A row of a snow fence is usually overloaded and becomes danger with falling snow. Snow fences are useful when they are placed in rows as a snow guard system would be, but they become very expensive sometimes exceeding the cost of the roof. You can get a whole lot less snow guards on sites like http://www.roofthings.com you might be able to install two snow fences.
