Why are snow guards and snow rail so important?
The answer is simple. Snow Guards and snow rail protect people and the material things we value from being damaged or destroyed by falling snow and ice. When snow falls off the roof in one large sheet, it is called a rooftop avalanche. When conditions are right snow will come off any type or roof in this way. Say goodbye to anything below it.
The most common type of roof where rooftop avalanches occur are metal roofs. This would include standing seam metal roofs and exposed fastened metal roofs. Because of the nature of snow and metal, once the snow falls it will freeze itself the to roof. One would think this would be permanent, but snow is like a blanket anything warm bodied underneath the blanket will trap the heat. A roof or a house is not warm bodied, but the people that live inside the house are. When it is cold outside, the heat is turned up inside of the house, and we all know that heat rises. That being said, the roof is were most heat from inside the house escapes to the outside of the house. This is a natural process, but when a blanket of snow covers the roof, the heat is trapped beneath the snow surface causing the under layer of snow to melt. Now instead of the snow being frozen to the metal roof surface, it now sits on a slick wet surface. Then as avalanches occur in mountain top, all it takes is one thing to trigger an avalanche and it all comes down at once. The cause for a rooftop avalanche off other roof types varies, but this is an example of why rooftop avalanches generally occur on metal roof surfaces.
Sno Shield's double deck mount snow rail is a perfect solution for the scenario described above. A double bar snow rail system could also be called "a snow fence for roofs". Use Sno Shield's deck mount snow fence roof systems in areas where the roof snow load is considered medium to heavy (Note: In medium-light snow load areas it can be used in combination with a single deck mount snow rail.) The 2 bar deck mount snow fence will not keep the roof surface from becoming slick with snow melt water, but it will keep the snow on the roof when it would have otherwise come off.
This double deck mount snow fence roof system is by far our most popular snow fence product. While it will penetrate the roof surface, any leaking is prevented using a sealant such as the ChemLink DuraSil. This product is well liked for other reasons as well:
- It is easy to install,
- Looks good on the roof and
- it really keeps the snow on the roof
In summary, the double pipe Sno Shield Snow Rail Deck Mount is a pad-style snow fence roof system used for medium snow retention. It is a continuous two pipe style snow guard system that helps prevent rooftop avalanches off of metal roofs such as standing seam metal roofs, or non-standing seam metal roofs, shingled roofs or slate roofs.
