Three-pipe Snow Fence System Snow Guards in Jackson, WY, USA Standing seam metal roof with Snow guards to keep snow from sliding off the roof too quickly. A snow guard is a device used to retain snow and ice from falling from one surface to a lower one; in contemporary usage, they are installed to prevent snow/ice pack from avalanching and damaging people, plants, and property below.
Ice dams may result in leaks through the roofing material, possibly resulting in damaged ceilings, walls, roof structure and insulation, or injury when the ice dam falls off or from attempts to remove ice dams. [1] The melting of roof snow comes from the combination of three basic causes: [2] Air temperatures well below freezing.
Foam glass is fireproof, waterproof, non-toxic, corrosion-resistant, non-aging, non-radioactive, and insulating. It is a stable building exterior wall and roof insulation and sound insulation material. Foam glass does not absorb water. The cells are mostly closed, so there is no capillary rise.
Installation is very streamlined and a rapid process. Depending on the size of the roof and the experience of the crew, it is possible to remove old shingles and apply new ones on 2-3 houses in one day. Life span varies. Use only on slanted roofs. [4] Rubber shingle, an alternative to asphalt shingle, slate, shake or tile.
Styrofoam insulation extruded polystyrene foam (XPS), owned and manufactured by DuPont. Styrofoam is a genericized trademarked brand of closed-cell extruded polystyrene foam (XPS), manufactured to provide continuous building insulation board used in walls, roofs, and foundations as thermal insulation and as a water barrier.
In the United States, the International Building Code and ASTM International define Exterior Insulation and Finish System (EIFS) as a non-load-bearing exterior wall cladding system that consists of an insulation board attached either adhesively, mechanically, or both, to the substrate; an integrally reinforced base coat; and a textured protective finish coat.

Screen gutter guards are among the most common and most effective. They can be snapped on or mounted, made of metal or plastic. Micromesh gutter guards provide the most protection from small and large debris. [33] PVC type gutter guards are a less costly option, however, they tend to quickly become brittle due to sun exposure.
