Snow guards are often overlooked when it comes to roof maintenance and protection. They are installed to keep snow from sliding off the roof in large quantities, preventing potential hazards and damage to property and people below. However, there is a common misconception that the installation of snow guards can actually cause damage to the roof itself. In this article, we will delve deeper into the topic and discuss whether snow guards can indeed damage your roof or if they are a necessary component for roof safety.
Understanding the Purpose of Snow Guards
Before determining whether snow guards can damage your roof, it is important to understand their purpose. Snow guards are installed on sloped roofs to prevent snow and ice buildup from sliding off in large quantities. When snow accumulates on the roof, it can form a heavy mass that can slide down suddenly. This can pose risks to pedestrians, vehicles, and even the structure itself. Snow guards help break up the snowpack, evenly distributing the weight and allowing it to melt or slide off in a controlled manner. They essentially act as a barrier, promoting the safe release of snow and preventing dangerous roof avalanches.
The Composition of Snow Guards
Historically, snow guards were made from metal or wood, and their installation involved drilling holes into the roof. This process often caused damage to the roofing material and compromised the integrity of the roof system. However, modern snow guards are built with the intention of minimizing roof damage. They are typically made from non-corrosive metals, such as aluminum, stainless steel, or polycarbonate, and are attached using adhesive or clamps that do not penetrate the roof surface.
Potential Risks and Damages
While snow guards are designed to prevent damage, it is crucial to consider the potential risks they may pose to the roof. One concern is that improperly installed snow guards can create weak points in the roof system. If the installation is not completed correctly, the snow guards may apply undue pressure on the roofing material, leading to cracks or leaks. Additionally, if the snow guards are not adequately spaced or placed too low on the roof, they can trap moisture or cause ice dams to form.
Proper Installation and Maintenance
To avoid potential damage caused by snow guards, it is essential to ensure their proper installation and regular maintenance. Hiring experienced professionals who specialize in snow guard installation is crucial to minimize any risks. They will be able to determine the appropriate location, spacing, and type of snow guard based on your specific roof design and geographical location.
Periodic inspection and maintenance are also important to address any issues that may arise with snow guards. Clearing debris, such as leaves or branches, from the snow guards will allow them to function optimally. Additionally, inspecting the adhesive or clamps periodically will ensure they remain secure and do not cause any damage to the roof.
While there is a potential for snow guards to cause damage to your roof if not installed or maintained properly, this risk can be mitigated by using modern, non-intrusive snow guard systems and hiring experienced professionals for installation. The benefits of snow guards in preventing roof avalanches and protecting both property and individuals below outweigh the potential risks when installed correctly. Therefore, it is highly recommended to consider the installation of snow guards if you live in an area prone to heavy snowfall.
