Snowfall is beautiful and with winter sports like skiing and sledging, it is also a lot of fun. All the roofs get covered with the falling snow and the entire area appears to be draped in a white blanket. However, this soft white snow on the roof tops slowly transforms into solid ice sheets, which can be extremely slippery, and result in numerous avalanches every year.
To protect your house and family from snowfall damage, you should install snow guards for metal roofs. Metal roofs with slopes between 30 to 45 degrees are most precarious and cause most avalanches. If the roof has a steeper slope than that, then the snows slips and prevents a huge snow buildup; and if the roof is flatter, then it decreases the chances of an avalanche because it requires more force to move the snow pack.
Snow sheds, fences, avalanche net and snow guards act like barricades to stop hazardous snow movements. Traditionally, people layered their roofs with stones and logs to increase resistance and protect themselves from seasonal snowfall. In the present day, contemporary snow guards for roofs have replaced these conventional methods of preventing snow slides.
What are snow guards?
Snow guards are defensive obstructions mounted on the rooftops of buildings and houses to prevent snow from falling on the ground below. These guards are fixed in rows and hold the snow effectively so that it falls in small quantities or just melts completely. The number of guards to be installed and the manner in which they should be placed depends upon the construction and style of the roof. Often, heat tapes are also installed with these guards to melt the accumulated snow and offer enhanced avalanche shield.
Selecting the right snow guards for metal roofs
These days a wide variety of snow guards are available in the market. They can be made of plastic, copper, aluminum or poly carbonate. The type of guard, which you should install on your rooftop, depends on the roof’s material. Roofs of most houses in cold areas are made of metal and the best type of roof guards for such rooftops is metal snow guard. Metal guards can be installed on both new and existing roofs.
