From this article you will learn what kind of snow guards are needed for standing seam metal roofs. The question of snow guards in Toronto and in Ontario area overall is always on agenda, because the winters are cold and snowy.
Standing seam metal roof like any other roof requires safety snow holds installed.
Besides the fact that they provide snow retention for folding roof, snow stops also, ensure safety and facilitate the maintenance of the roof:
Therefore, it is better to comply with safety standards and install snow safety system on the roof.
There are several types of snow guards for metal roofs:
Angular stoppers are inexpensive constructions made of sheet steel; They have anti-corrosion and polymer coating; easy to install; designed for inconsiderable snow mass; best suited for lightweight construction;
Grid-like stoppers are installed on the edge of the roof and form a barrier for snow. This kind of system may even include decorative elements. The system is installed with the help of special supports or is simply nailed to the roof.
Tubular stoppers are very simple in construction: two metal tubes are aligned upright to the edge of the eave of the roof. They are secured with clamping mechanisms bolted to the roof. Sometimes when the area is known for heavy snowfalls or the roof is steep, it is recommended to use multiple rows of snow guards might be used to increase hold in the snow. The tubular design finds its perfect use with the standing seam.
The installation of safety system for standing seam is slightly different: the legs are pulled up to the crest of the seam and the integrity of the coating remains intact.
Tubular snow holders are the most durable, therefore, unlike other types, they are recommended for large snow masses, as well as for large or long roof slopes, on long slopes. As stated above, tubular snow guard is a prefabricated structure, which consists of:
The most practical and durable tubular holders are made of hot-dip galvanized steel. Often a zinc layer has also a colorful coating which not only enhances the look but also adds anti-corrosion protection.
In addition to tubes and brackets, the snow guard kit includes weatherproof EPDM washers and screws for fastening the brackets as well as special plates and bolts designed specifically for the standing seam roof.
