The mushroom metal thing on roofs.

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. It s no surprise that mushroom roofs are most often found on cottages and other rural properties. 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. As heat leaks out through the roof it can melt a layer on the bottom of the snowpack letting it slide.

Ice dams are caused by insulation ventilation. These oversized roof edges create a dramatic effect one that adds elements of whimsy and fantasy to any home while retaining a strong sense of harmony with nature. Metal shingles are formed with an airspace between the metal and the roof deck. The guy who called them snow guards was correct.

That airspace acts as a thermal break to stop the conductive flow of heat from the surface of the roof into the attic. The hooks come in all types of designs and are designed to keep the snow on the roof. They are to prevent snow drifts from falling on people. It has nothing to do whatsoever with ice dams.
