Snow guard

A snow guard is a device used to retain snow and ice on a sloped roof, allowing it to melt or evacuate gradually rather than falling off in large, potentially dangerous chunks. Snow guards are essential in regions with heavy snowfall to prevent damage to property and injury to people.

Function

Snow guards work by creating friction and holding the snow in place. This prevents the sudden release of snow and ice, which can cause damage to roofing materials, gutters, and other structures. They are particularly important for metal roofs, which have a smooth surface that allows snow to slide off easily.

Types of Snow Guards

There are several types of snow guards, including:

• Pad-style snow guards: These are individual units that are attached to the roof. They are often made of metal or polycarbonate and are designed to hold snow in place.
• Bar-style snow guards: These consist of horizontal bars that run across the roof. They are typically used on larger roofs and can handle a greater volume of snow.
• Fence-style snow guards: These are similar to bar-style guards but have a more decorative appearance. They are often used on residential buildings.

Installation

Snow guards should be installed by a professional to ensure they are placed correctly and securely. The placement and number of snow guards depend on the roof's pitch, the type of roofing material, and the average snowfall in the area. Proper installation is crucial to their effectiveness.

Materials

Snow guards can be made from various materials, including:

• Metal: Common metals used include stainless steel, aluminum, and copper. Metal snow guards are durable and can withstand harsh weather conditions.
• Polycarbonate: This is a type of plastic that is strong and lightweight. Polycarbonate snow guards are often used on residential roofs.

Benefits

The primary benefits of snow guards include:

• Safety: Preventing large chunks of snow and ice from falling off the roof reduces the risk of injury to people and animals.
• Property protection: Snow guards help protect gutters, downspouts, and other roof structures from damage caused by falling snow and ice.
• Roof longevity: By preventing the sudden release of snow, snow guards can help extend the life of the roof by reducing the stress on roofing materials.
