AvatarByVictor Nealon Roof Installation


As winter approaches and the temperatures begin to drop, homeowners with metal roofs must consider the potential hazards of snow accumulation. While metal roofs are celebrated for their durability and longevity, they can also pose unique challenges when it comes to snow and ice management. This is where snow guards come into play. These essential devices help prevent dangerous avalanches of snow and ice from sliding off your roof all at once, protecting your property, landscaping, and anyone who might be below. If you’re looking to enhance the safety and functionality of your metal roof this winter, understanding how to install snow guards is a crucial step.

Snow guards come in various styles and materials, each designed to cater to different roof types and climates. The installation process can vary based on the specific design of your roof and the type of snow guards you choose. However, the general principles remain consistent: proper placement, secure attachment, and consideration of local weather patterns are vital to ensure that your snow guards effectively manage snow loads.

In this article, we will guide you through the essential steps and considerations for installing snow guards on a metal roof. From selecting the right type of guards to understanding the best installation techniques, you’ll gain the knowledge needed to protect your home from winter’s icy grip. Whether you’re a seasoned DIY

Preparation for Installation

Before installing snow guards on a metal roof, it’s essential to prepare adequately. This includes assessing the roof type, understanding the climate conditions, and gathering the necessary tools and materials.

First, identify the type of metal roofing you have, as different materials may require specific installation techniques. Additionally, consider local snowfall patterns, as heavier snow regions may necessitate more robust snow guards.

Materials Needed:

  • Snow guards (specific to your roof type)
  • Drill with metal drill bits
  • Measuring tape
  • Marking chalk
  • Safety goggles
  • Ladder or scaffolding
  • Silicone sealant (for weatherproofing)
  • Wrench or socket set

Measuring and Marking Locations

Accurate measurement is critical to the effective installation of snow guards. The placement of the guards should be strategic, typically at the lower edge of the roof and where snow is most likely to accumulate.

  1. Measure the total length of the roof edge where snow guards will be installed.
  2. Determine spacing based on the type and size of the snow guards. Common spacing is between 24 to 36 inches, but this can vary based on snowfall and roof pitch.
  3. Use marking chalk to indicate where each snow guard will be installed.

Installation Process

Begin the installation by securing the snow guards to the roof. Follow these steps to ensure proper placement:

  • Use a drill to create pilot holes at the marked locations. If your roof is insulated, be cautious not to penetrate through to the interior.
  • Align the snow guard over the pilot holes and insert the screws.
  • Tighten the screws securely, ensuring a watertight seal.

Note: If using a rubber washer screw, ensure the rubber is compressed adequately to prevent leaks.

Snow Guard Type Recommended Spacing Material Consideration
Standard Snow Guard 24-30 inches Aluminum, Stainless Steel
Heavy-Duty Snow Guard 30-36 inches Steel, Reinforced Plastic
Adhesive Snow Guard Varies Polycarbonate

Weatherproofing and Final Adjustments

After securing the snow guards, it is essential to weatherproof the installation. Apply silicone sealant around the base of each snow guard to prevent moisture penetration and potential rusting.

Finally, conduct a thorough inspection of all installations. Ensure that each guard is firmly attached and that there are no gaps or loose components. This step is crucial to ensure the longevity and effectiveness of the snow guards.

By following these detailed steps, you can effectively install snow guards on a metal roof, ensuring proper snow management and protection from potential damage.

Choosing the Right Type of Snow Guards

When selecting snow guards for a metal roof, consider the following types and their suitability for different roof styles and climates:

  • Pad Style Snow Guards: Best for flat or low-slope roofs. They provide a wide base for snow accumulation.
  • Vertical Style Snow Guards: Ideal for steeper roofs, allowing snow to slide down without releasing in large quantities.
  • Bar Style Snow Guards: Effective for roofs with high snow loads, offering a continuous barrier to control snow movement.
Type of Snow Guard Best For Advantages
Pad Style Flat/Low-slope roofs Wide base for snow support
Vertical Style Steep roofs Prevents sudden snow slides
Bar Style High snow load conditions Continuous barrier

Tools and Materials Needed

Before starting the installation, gather the necessary tools and materials:

  • Tools:
  • Drill
  • Screwdriver
  • Measuring tape
  • Level
  • Safety glasses
  • Ladder
  • Materials:
  • Snow guards (appropriate type and number)
  • Stainless steel screws
  • Sealant (for waterproofing)
  • Roof brackets (if required)

Preparing the Roof Surface

Ensure the roof surface is clean and dry before installation. Follow these steps:

  1. Inspect the roof for any existing damage or debris. Clean the area using a broom or blower.
  2. Check the roof’s slope and drainage patterns to determine the optimal placement of snow guards.
  3. Mark the locations for installation using a chalk line, ensuring proper spacing based on the manufacturer’s recommendations.

Installing the Snow Guards

Follow these steps to install snow guards effectively:

  1. Positioning: Align the snow guards according to the marked lines. Ensure they are evenly spaced to provide adequate support.
  2. Drilling: Pre-drill holes for the screws to prevent metal from cracking. Make sure to drill through the metal and into the underlying structure if possible.
  3. Securing: Attach each snow guard using stainless steel screws, ensuring they are tightened securely. Apply sealant around the screws to prevent leaks.
  4. Level Check: Use a level to verify that each snow guard is correctly positioned before moving to the next.

Post-Installation Inspection

After installation, conduct a thorough inspection:

  • Ensure all guards are securely fastened and level.
  • Check for any gaps or uneven surfaces that could allow water infiltration.
  • Confirm that the spacing between guards is consistent and adheres to the manufacturer’s guidelines.

Maintenance Tips for Snow Guards

Regular maintenance ensures the longevity and effectiveness of snow guards:

  • Inspect snow guards annually for any signs of wear or damage.
  • Clean snow guard surfaces to prevent ice buildup and ensure proper functioning.
  • Reapply sealant as necessary to maintain waterproofing around screws and joints.

Hi, I’m Victor - the voice behind Element Roofing.

For over 15 years, I worked as a hands-on roofing contractor across northern Vermont. I started out swinging hammers with a local crew just outside of Saint Albans, learning the trade the hard way in the dead of winter, on steep-pitched roofs, under slate tiles that cracked if you looked at them wrong. Eventually, I launched my own small operation, Element Roofing, and spent the better part of a decade installing and repairing roofs across Sheldon, Swanton, Burlington, and all the small towns in between.

But people wanted to understand what was happening over their heads. They asked smart questions. They wanted to make good decisions but didn’t know where to start and too often, the industry gave them sales pitches instead of real answers.

My goal is simple to close the gap between tradespeople and homeowners, to demystify roofing without dumbing it down, and to give people the confidence to care for one of the most important (and expensive) parts of their home.

So feel free to dig in, explore, and take control of what’s over your head. We’re here to help from rafter to ridge.
