Igloos might last for about six weeks, providing it can withstand the temperature changes and the harsh weather. Igloos depend upon the snow, and snow depends on the cold. All igloos will collapse when the weather becomes too warm. The spring equinox, which is March 22nd, marks the time when the days last longer.
It is during this time that the snow melts, and the structure of the igloo diminishes. Mid May is generally the cutoff time for the survival of the igloo, even in the High Arctic. The more worn an igloo gets, the colder it becomes, which means that you need to build a new igloo every few weeks or so.
The extent to which an igloo house lasts depends on the weather condition of the environment where it is being built. However, some igloos are built to be permanent, while most others are temporal. Some igloos are built to serve a very long time purpose. The materials with which they are built is a crucial determinant of how long an igloo is going to last. But the major or the common igloos are built with ordinary closely packed snow, which is in the form of ice, cut at a particular dimensional area.
The igloo houses are usually built during the winter period, because that is the time that snows dominate the land, for the snowy area. This snow only lasts as long as the weather is cold. Therefore, the normal igloos also last as long as the winter period lasts. Immediately the temperature of the atmosphere becomes high; that is, when the atmospheric condition becomes hot, the igloos start to melt.
