An igloo constructed with snow blocks will thermally insulate its interior from its exterior. It is known that, whilst snow itself has a temperature below the freezing point of water 0 °C (32 °F), it has excellent thermally insulative properties as it consists of air pockets trapped between ice crystals.

Instruments measured weather conditions on the roof, temperatures inside the building and throughout the roof layers, and air conditioning and total building power consumption. Measurements were taken with the original black rubber roofing membrane and then after replacement with a white vinyl roof with the same insulation and HVAC systems in ...
An ice dam is an ice build-up on the eaves of sloped roofs of heated buildings that results from melting snow under a snow pack reaching the eave and freezing there. Freezing at the eave impedes the drainage of meltwater, which adds to the ice dam and causes backup of the meltwater, which may cause water leakage into the roof and consequent ...
“The more salt, the more the freezing point is lowered,” Julienne Stroeve, senior scientist at the National Snow and Ice Data Center at the University of Colorado, tells Popular Mechanics.
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.

[9] [20] As per Chen et al., "to overcome this issue, dynamically switchable coatings have been developed to prevent overcooling in winter or cold environments." [ 19 ] The detriments of overcooling can be reduced by modulation of PDRCs, harnessing their passive cooling abilities during summer, while modifying them to passively heat during winter.
