Snow
Retention systems are widely implemented in Europe as a means
of preventing roof damage due to the sliding of snow and ice
masses that accumulate on roofs during winter months in alpine
regions. As snow accumulates and is retained on a roof, it serves
as an insulating blanket to promote energy efficiency. Furthermore,
by retaining snow on the roof of a building and allowing even
snow melt-off, injuries to residents/guests and property below
the roof of a building can be avoided, saving money and limiting
the possibility of personal loss.
