Southern and Central parts of the country have experienced significant snowfall, sleet and rainfall in the past few days posing accidental risks.
The Finnish Environment Institute-SYKE has advised that roofs of huge halls should be checked to avoid the risk of collapsing.
Houses based on previous experiences in relation to the endurance of roofs are not categorised in the risk groups.
Instead, the risk is that of home owners themselves falling down when climbing the houses. It is always advisable to get help from the professionals to clear the snow from the roofs, points out SYKE.

Snow weight depends on its density, and therefore, snow-load on the roof cannot solely be assessed on the thickness of snow layer.
In recent years, air-supported structures like the so-called "bubble halls" have been affected by snow loads which resulted to injuries.
In 2013, a ten-year old died when the roof of a school collapsed.
