Snow rails, also known as snow stops, are devices that are installed on a roof to prevent snow and ice from sliding off the roof and causing damage to the building or to people below. They are similar to snow guards, but are typically larger and cover a wider area of the roof.
Snow rails are typically made of metal or plastic and are installed along the roof ridge or eave to prevent snow from sliding off the roof. They are designed to allow snow to melt gradually, instead of sliding off the roof in large sheets, which can cause damage to the roof, gutters, and other building components, as well as increase the risk of injury to people below.
Snow rails are especially important on buildings with overhangs, gutters, or other features that can be damaged by falling snow and ice. They are also commonly used on residential homes, commercial buildings, and other structures where the risk of snow and ice damage is high.
In order to be effective, snow rails must be installed correctly and must be the appropriate size and type for the roof they are being used on. It is important to work with a qualified roofing professional when installing snow rails to ensure that they are installed correctly and will provide the desired level of protection.
