The metal bits are positioned out on the eaves where that part of the snowpack stays frozen and the little teeth help make a wall of snow and hold everything solid. 7 things to know before choosing a metal roof if your current roof is the root of your headache and maybe even a long list of costly home repairs consider these metal roofing pros and cons.
