Understanding Snow Guards: Why Are They Necessary?

Snow guards, also known as snow retention systems, are strategically placed devices designed to hold snow in place on roofs. By preventing large sheets of snow from sliding off abruptly, they protect gutters, landscaping, and anyone standing below. Here’s why snow guards are essential:

Safety: Uncontrolled snow avalanches off metal roofs can fall down on walkways, cars, people, and pets. Installing snow guards ensures safety for everyone around your property.

Property Protection: Snow avalanches can damage gutters, landscaping, and other structures. Snow guards prevent these sudden slides, preserving your property.

Reduced Maintenance: Instead of battling giant snowdrifts sliding off your roof, snow guards allow snow to slide off in smaller, controlled quantities. This makes winter home maintenance much easier.

Types of Snow Guards for Metal Roofs

Before diving into installation, it’s crucial to understand the different types of snow guards available for metal roofs and determine what are the best snow guards for metal roofs:

Type 1: Clamp-On Snow Guards:

These snow guards are designed to attach to the raised portion of a standing seam metal roof. They offer a secure grip without the need for adhesive, clamping onto the seam to hold snow in place. The advantage of clamp-on snow guards is that they avoid puncturing the roof, providing effective snow retention without compromising the roof’s integrity.

Type 2: Screw-On Snow Guards:

Screw-on snow guards are installed by directly screwing them onto the roof surface. While they are effective at preventing snow buildup, this installation method requires drilling into the roof, which may not be suitable for all roofing systems. It’s important to ensure proper placement and spacing to achieve optimal snow retention without compromising the roof’s structural integrity.

Type 2: Screw-On Snow Guards:

Type 3: Glue-On Snow Guards:

These snow guards adhere to the roof using a strong adhesive. Commonly used for corrugated metal roofs, glue-on snow guards offer a secure attachment without the need for drilling or clamping. This installation method is preferred for roofs where drilling or clamping may not be feasible or desired. It’s important to follow manufacturer instructions for proper adhesive application to ensure a secure and long-lasting installation.

How To Install Snow Guards For Metal Roofs

Follow these detailed steps to install snow guards on metal roofs effectively:

Step 1: Plan Based on Roof Pitch

Before installing snow guards on your metal roof, it’s essential to assess the roof pitch. The pitch determines the layout and positioning of the snow guards. A steeper pitch typically requires more frequent spacing of snow guards to evenly distribute the weight of snow and ice. Using a pitch gauge or consulting a roofing professional can help accurately determine the roof pitch.

Step 2: Stagger the Rows

Once you’ve determined the roof pitch, it’s time to stagger the rows of snow guards. Staggered rows prevent snow from accumulating in one area, reducing the risk of ice dams and potential roof damage. Start by installing the first row of snow guards no more than halfway up the roof, then alternate the placement of subsequent rows to create a staggered pattern. Proper spacing between rows is crucial for effective snow retention.

Step 3: Prepare the Roof Surface

Preparing the roof surface is essential for ensuring proper adhesion or attachment of the snow guards. Begin by thoroughly cleaning the metal roof surface to remove any dirt, debris, or residues that could interfere with adhesion. Use a gentle detergent and water to clean the surface, rinsing thoroughly to remove all traces of cleaning agents. Allow the roof surface to dry completely before proceeding with the installation of snow guards.

Step 4: Attach the Snow Guards

Once the roof surface is clean and dry, it’s time to attach the snow guards. Depending on the type of snow guards being installed, use appropriate adhesive or clamps to secure them to the roof. Follow the manufacturer’s instructions carefully to ensure proper attachment and alignment of the snow guards. Proper attachment is crucial for the effectiveness of the snow guard system in preventing snow and ice buildup.

Step 5: Spacing and Quantity

Proper spacing and quantity of snow guards are essential for ensuring effective snow retention. For panels less than 16 inches wide, install one snow guard per panel per row. For wider panels, use two snow guards per panel per row to provide adequate support and prevent snow accumulation. Maintain spacing no more than 12 inches horizontally to evenly distribute the weight of snow across the roof surface.

Step 6: Consider Reinforcement

In some cases, additional reinforcement may be necessary to support the weight of snow and ice on the roof. If the roof structure is not adequately reinforced, the weight of snow and ice can cause damage to the roof panels and underlying structure. Consider adding reinforcement beneath the metal panels, such as using 2×4 spacers between trusses on the underside of the sheeting, to provide additional support and prevent damage from heavy snow loads.

Step 7: Ensure Proper Bonding

Proper bonding of the snow guards to the roof surface is essential for long-lasting installation. If using solder to attach the snow guards, ensure that the solder is sufficiently melted to create a strong and secure bond with the roof surface. Apply heat evenly to the snow guards to ensure proper bonding and alignment. Regularly inspect the snow guards to ensure they remain securely attached to the roof surface and make any necessary repairs or adjustments as needed.

Conclusion About Install Snow Guards

In conclusion, ensuring proper snow guard installation on your metal roof is essential for safety and property protection during winter. By following the guidelines in this guide, you’ll have peace of mind knowing that your roof is well-prepared for icy conditions.

FAQs

Where should snow guards be placed on a metal roof?

Snow guards should be strategically placed along the lower portion of the roof, typically above doorways, walkways, or areas with pedestrian traffic. Additionally, they should be installed in areas prone to snow accumulation, such as valleys or roof transitions.

How do you install a metal snow guard?

To install a metal snow guard, first, clean the roof surface thoroughly. Then, use adhesive or screws to securely attach the snow guard to the roof according to manufacturer instructions. Ensure proper spacing and alignment for effective snow retention.

How do I keep snow from sliding off my metal roof?

Installing snow guards is the most effective way to prevent snow from sliding off a metal roof. These guards create friction, holding snow in place and allowing it to melt gradually. Properly installed snow guards distribute the weight of snow evenly across the roof surface, reducing the risk of sudden snow slides.

Where do you put ice and water shield on a metal roof?

Ice and water shield should be installed along the eaves and in valleys of a metal roof to provide additional protection against water infiltration. Apply the shield directly onto the roof deck before installing the metal panels, ensuring proper coverage and adherence to manufacturer guidelines.
