Living in areas prone to heavy snowfall requires homeowners and property owners to understand the concept of maximum snow load on a roof. Snow load refers to the weight of snow accumulation on a roof, which can pose a significant risk if it exceeds the roof’s capacity. RGB Construction, a reputable roofing company in New Jersey, understands the importance of assessing snow load and offers expert guidance and services to ensure the safety and durability of roofs in snow-prone regions.
Winter is almost here, and you want to get your roof ready for the harsh weather and cold temperatures. Snow can cause damage to your roof, which can affect the structural integrity of your home. Knowing the snow load is very important to prevent any problems with the structure. Here are a few things you will want to know to stay safe during the winter months.
Understanding Maximum Snow Load
What is Maximum Snow Load?
Maximum snow load refers to the maximum weight that a roof can safely bear without being compromised or at risk of structural failure. It is determined by various factors, including the geographical location, roof design, pitch, material, and building codes. Snow load is typically measured in pounds per square foot (PSF) and varies from region to region.
Factors Affecting Snow Load
Several factors influence the maximum snow load on a roof. These factors include:
- Geographical Location: Areas with heavy snowfall are more likely to experience higher snow loads than regions with milder winters.
- Roof Pitch: The steepness or pitch of a roof affects how snow accumulates. Steeper roofs tend to shed snow more efficiently, reducing the overall snow load.
- Roof Design: Complex roof designs with valleys, dormers, or multiple slopes can trap snow, leading to increased snow load in specific areas.
- Roof Material: Different roofing materials have varying capacities to handle snow load. Metal roofs, for example, are often preferred in snow-prone regions due to their ability to shed snow easily.
- Building Codes: Local building codes dictate the minimum requirements for roof design and snow load capacity in a specific area. Compliance with these codes ensures that roofs are built to withstand anticipated snow loads.
Assessing Maximum Snow Load
To determine the maximum snow load on a roof, it is crucial to consider the factors mentioned earlier and consult with a professional roofing company like RGB Construction. They have a team of experienced roofers in New Jersey who can accurately assess the snow load capacity of your roof and provide appropriate recommendations.
Engaging Professional Roofing Services
RGB Construction offers comprehensive roof inspection services to assess the maximum snow load capacity of roofs. Their team of skilled roofers in New Jersey will conduct a thorough examination, considering factors such as roof design, pitch, and materials. They will then provide you with a detailed report outlining the maximum snow load your roof can handle and any necessary measures to ensure its safety.
How Much Snow Can Your Roof Handle?
Many factors can affect the maximum snow load on your roof. Generally, average roofs can support about 20 pounds of heavily packed snow per inch of the roof’s surface. Sometimes, your roof can hold more fresh snow, but the snow will melt and become impacted over time. Those heavier snows can cause significant damage to your roof.
Here are a few calculations to keep in mind when determining your maximum snow load. Look at the weights of the various types of snow.
- Fresh snow: 3.75 pounds per cubic foot
- Settled snow: 15.61 pounds per cubic foot
- Very wet snow: 46.82 pounds per cubic foot
- Ice: 57.25 pounds per cubic foot
Once you know what type of snow you have on the roof, you can calculate the snow load with this formula:
Density (pounds by cubic foot) x depth of snow (foot)
However, that formula will only work for flat roofs. Those types of roofs are at the greatest risk for snow load damage. If you have a steep incline on your roof, it will allow the snow to fall off the surface.
Do you want to remove the snow from the roof as soon as it lands on the surface? No, you don’t have to go up to the roof if there are just a few inches of fresh snow. However, when there is a buildup of snow and ice, it can cause damage over time.
Densely packed or wet snow is heavier than freshly fallen snow. When you leave it on the roof, that packed snow will turn into ice. In turn, the ice creates dams, which can lead to structural problems. When the ice melts, you might notice issues with water damage around your home. Once that occurs, you could even have the roof collapse into the building.
How Much Snow Is Too Much for the Roof?
As previously mentioned, a typical roof can support about 20 inches of packed snow. When you have about 10 to 12 inches of fresh snow, that is only the equivalent of 1 inch of water. Today, modern roofs are more structurally sound than in the past. With that in mind, these roofs can support double the typical snow load, usually around 40 to 45 inches of fresh snow. If you have ice on the roof, it is slightly heavier than fresh snow. One inch of ice is the equivalent of 1 foot of snow.
Keeping Snow Off the Roof
You might think that a hot roof will prevent snow from sticking, but the opposite is true. One of the best ways to prevent snow from staying on your roof is to keep the surface cold. A cold roof prevents ice and snow from sticking, melting, and refreezing on the surface. There are several ways to lower the roof’s temperature, including improving the insulation and ventilation in the attic. You may also want to fill in cracks, add roof vents, and plug any air leaks.
When the snow piles up, you may want to take a rake and carefully remove the snow from the roof’s surface. There are a few points you need to keep in mind when clearing snow. Scraping or clearing off all the snow can actually damage the shingles. You will want to leave about 2 inches of snow on the roof’s surface. When it comes time to remove snow, never climb to the top of the roof. Ice can create an extremely hazardous surface, causing you to slip and fall. If you must clear the snow, always use a roof rake to prevent any injuries.
If there are any icicles on the roof, you do want to take a more cautious approach. Knocking down ice might seem like a smart move. However, hitting an icicle can cause damage to your downspouts, gutters, and other components on the roof. When large icicles form on your roof, you will want to call a professional to remove them.
How To Melt Snow on a Roof
If you have snow on your roof, can you melt it? You will have to be careful with any of these processes. Cooling down the attic and roof is the best approach. Some homeowners will apply a chemical deicer to the roof. Those deicers can often prevent snow and ice from forming on the surface. Also, installing snow guards will stop large amounts of snow from falling off the roof and causing damage. For those who are really concerned about the amount of snow on their roofs, it may be time to call a professional roofing company to remove the snow from the surface.
Along with the snow, you also have to worry about ice dams. When ice builds up on the roof, it can create a block that will prevent any snow from falling off your roof. Maintaining ventilation and insulation in the attic region will prevent many of these problems. Some products on the market can help to stop ice dams from forming. Once again, you will want to talk to a professional roofer to find the best solution to prevent ice dams from damaging your roof.
