to our blog, fellow homeowners and building enthusiasts! If you live in an area with heavy snowfall, you know the struggle of constantly worrying about your metal roof collapsing under the weight of all that fluffy white stuff. While metal roofs are known for their durability and low maintenance, they can still be susceptible to damage from excessive snow load.
But fear not – we have some expert tips and tricks to share with you on how to increase snow load on metal roof. So sit back, grab a hot cup of cocoa (or coffee), and let us guide you through this important topic in a friendly and informative tone.
Whether for your home or business, these tips will help ensure that your metal roof can withstand even the heaviest of winter storms.
What Will You Need?
Before we get into the nitty-gritty of increasing snow load on your metal roof, let’s review the basic tools and materials you will need for this task. Don’t worry. It’s nothing too complex – just some common items you can easily find at any hardware store:
- A ladder (preferably a sturdy one)
- Snow rake or shovel
- Soft broom or brush
- Protective gear (gloves, goggles)
- Calcium chloride or other ice melt product
Now that you have your supplies ready, let’s dive into the steps you can take to increase the snow load on your metal roof.
10 Easy Steps on How to Increase Snow Load on Metal Roof
1. Add Snow Guards
Snow guards are metal or plastic devices that are installed on the roof to help prevent snow from sliding off in large sheets. They can be attached with screws or adhesive and should be evenly spaced across the top.
Snow guards work by creating friction between the snow and the roof, allowing it to melt and slide off in smaller amounts gradually.
2. Increase Roof Pitch
One way to increase the snow load capacity of a metal roof is to increase its pitch. This means making the angle of the roof steeper, which allows for better shedding of snow and prevents it from accumulating too heavily. However, this option may require significant structural changes and should be done by a professional.
3. Reinforce Roof Structure
If your metal roof cannot support heavy snow loads, reinforcing the structure may be necessary. This could involve adding additional trusses or supports, as well as strengthening existing ones. It’s essential to consult with a structural engineer before making any modifications to ensure they are done correctly and safely.
4. Regular Roof Maintenance
Regular maintenance is crucial to ensure the longevity of your metal roof and its ability to sustain heavy snow loads. This includes regular inspections for any signs of damage or wear and tear, cleaning the gutters and downspouts to prevent ice dams, and removing any debris that might accumulate on the roof. Proper maintenance will help you identify potential issues early and take the necessary steps to rectify them before snowfall.
5. Install Heating Cables
Heating cables are a valuable tool in managing snow load on metal roofs. They are designed to heat up and melt the snow, preventing accumulation. Run the heat cables in a zigzag pattern along the roof edge and in areas where snow and ice build-up. This can be a DIY task.
However, consider hiring a professional for installation to ensure optimal performance and safety. Remember to turn on the heating cables before a snowfall to prevent the build-up from the start.
6. Use Ice Dam Membranes
Ice dam membranes are waterproof materials installed on your roof to prevent ice dams from forming. These are especially useful in parts of the top where snow and ice accumulate, like the valleys, edges, and around chimneys or vents. Ice dam membranes create a barrier that prevents water from seeping into the roof structure, thus protecting your metal roof from potential water damage. They are typically installed when the top is being built or replaced but can also be added later as a proactive measure against heavy snow load.
7. Apply a Liquid De-Icer
Liquid de-icers are chemical solutions you can spray onto the roof to help melt the snow and ice. They work by lowering the freezing point of water, thus preventing the snow from sticking to the metal surface. You can apply a liquid de-icer as a preventative measure before a snowfall or after the snow has accumulated. Be sure to follow the manufacturer’s instructions for best results. Choose eco-friendly options that will not harm your property’s landscaping or the local wildlife.
8. Install Additional Insulation
Adding more insulation under your metal roof can help increase the roof’s snow load capacity by preventing heat loss. This reduces the chances of snow melting and refreezing, which can lead to heavy ice dams.
Insulation materials such as spray foam or insulating panels are commonly used. This step may require professional installation to ensure the insulation is fitted correctly and effectively.
9. Regular Snow Removal
One of the most effective ways to manage snow load is by regularly removing snow from your roof. This can be done using a snow rake or shovel or by hiring professional snow removal services. Be careful to remove the snow evenly across the roof to prevent imbalance and potential collapse. Avoid using metal tools that can damage the roof surface, and always work from the ground if possible to ensure your safety.
10. Consult with Roofing Professionals
Lastly, always seek advice from roofing professionals when dealing with snow load issues. They have the necessary training and expertise to assess your roof’s condition, provide practical solutions, and perform necessary repairs or modifications. Remember, dealing with snow load is not just about preventing roof damage but also about ensuring the safety of your home or building.
By following these ten steps, you can increase the snow load capacity of your metal roof and protect it from potential damage caused by heavy snowfall.
5 Things You Should Avoid
- Ignoring Snow Accumulation: It’s tempting to ignore the snow on your metal roof and let nature do its job. However, ignoring substantial snow accumulation can lead to roof damage due to the excessive weight.
- Using Sharp Tools to Remove Snow: While it may seem like a good idea to use a shovel or other sharp tools to clear off the snow, this can damage the roof surface and reduce lifespan.
- Walking on the Roof: Walking on a metal roof, especially one that’s snow-covered, is dangerous and can cause damage to the roof structure. Always hire professionals to remove snow if needed.
- Neglecting Roof Inspection: It’s crucial to have your roof inspected regularly to check for any areas that might be weak or deteriorating. An unchecked weak spot can lead to roof collapse under heavy snow load.
- Forgetting to Increase Roof Strength: If you live in an area with heavy snowfall, you should proactively increase the strength of your metal roof to withstand higher snow loads. Consider this important step.
By avoiding these common mistakes, you can ensure that your metal roof remains in good condition even under heavy snow loads.
Does Roof Pitch Affect Snow Load?
Yes, the roof pitch does affect the snow load. The steeper the slope of your roof, the less likely it is for snow to accumulate and put excessive weight on your metal roof. This is because steep roofs allow snow to slide off easily, reducing the amount of snow that can accumulate.
On the other hand, flat or low-pitched roofs are more prone to snow accumulation and may require more frequent snow removal to avoid roof damage. It’s essential to consider the pitch of your roof when planning for heavy snowfall and taking necessary precautions.
It’s best to consult a roofing professional to determine the appropriate roof pitch for your area and ensure that your metal roof can handle the expected snow load. So, if you live in a room with heavy snowfall, pay attention to the slope of your roof when installing or repairing it.
What is the Best Roof Pitch for Heavy Snow Load?
When choosing the best roof pitch for heavy snow loads, there are a few factors to consider. Generally speaking, the steeper the roof pitch, the better it is at shedding snow. This is because steep roofs allow snow to slide off quickly and prevent accumulation. However, highly steep roofs can also be prone to ice dams and other issues.
The ideal roof pitch for heavy snow load is typically between 4:12 and 6:12, with a higher pitch being more beneficial in areas with frequent heavy snowfall. Additionally, it’s essential to consider the structural integrity of your roof and whether it can support the weight of a steeper pitch.
If you are unsure about the best roof pitch for your location, consult a professional contractor with experience in handling heavy snow loads. They can assess your roof and make recommendations based on your specific needs.
