The Mushroom Metal Thing On Roofs

Metal roofs can last 30 to 50 years longer than other roofing materials saving you money in the long term.

The mushroom metal thing on roofs.

Ice dams are caused by insulation ventilation. Metal shingles are formed with an airspace between the metal and the roof deck. It has nothing to do whatsoever with ice dams. They are there to prevent avalanches off the roof onto people plants etc.

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. That airspace acts as a thermal break to stop the conductive flow of heat from the surface of the roof into the attic. Plus cool metal roofing uses a reflective solar coating designed to minimize heat buildup and reduce air conditioning costs. The hooks come in all types of designs and are designed to keep the snow on the roof.

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. It s no surprise that mushroom roofs are most often found on cottages and other rural properties. The guy who called them snow guards was correct. As heat leaks out through the roof it can melt a layer on the bottom of the snowpack letting it slide.
