How Do Snow Rails Work And What Should I know About Them?
A snow rail, or snow fence, is used along the edge of slate roofs to prevent sudden and unexpected ice and snow avalanches. These can cause damage to people, cars, shrubbery and any other property underneath. The system can also include stainless steel expanded metal which keeps slates and other debris from coming off the roof and creating a fall hazard. A standard field array of snow breaks can also be included on the roof above the snow rail for maximum protection.
Snow rail fence brackets are installed parallel to, and approximately 24″ to 36″ from the eaves. The brackets should be spaced out at least 18-24″ but not more than 42″ – 48″ apart, depending on the roof pitch and the snow load that is expected. It is recommended that you utilize through bolts and backer plate on the underside of the roof deck for optimal stability. Bronze, brass or stainless steel pipe is recommended. Copper water pipe should not be used. Areas that expect a high snow load should use a three-pipe system. If you opt for a smaller system it will need an additional snow break array on the roof above the snow block.
Mounting snow rails can seem like a daunting task to undertake, but there is an option available to you. You can do the installation yourself or have it done by a pro. Many companies have the expertise to do it for you, which can save hassles, but you can still choose to do it yourself. It will be a bit more expensive if you have it professionally installed, but it could be worth the extra expense to avoid potential disgruntlement. If you decide to install it yourself, make sure you carefully read the instructions and make sure you do a little research ahead of time.
Snow rails are permanent and provide lifetime durability. Independent testing has shown that the certain rails can withstand almost 4,000 pounds of direct mechanical force. The rivets will not come out or shear and the brass bolts will remain intact. Moreover, bronze castings will not crack due to water or age.
This system is not cheap but you get what you pay for. In addition to the railing, you may require stainless steel expanded wire mesh to keep smaller items, such as slates, from falling through the rails. This and other snow retaining systems can be found all over the country.
