How Much Snow Is Too Much Snow for a Roof?

As winter is underway, it’s important to consider how much snow your roof can safely hold before sustaining damages. If you’re new to your home or have an old roof, this is an especially important issue to consider. When weather stations predict frigid temperatures and record snowfall in Ohio, it’s essential to be prepared and make sure that your roof is covered. No one wants their roof to be damaged, or even collapse, from the strain of a surprise snow load. So how much snow can a roof safely hold?

What Affects My Roof’s Snow Resistance?

Since every home is different, there is no universal answer to this question. The amount of snow that your roof can hold depends on a number of factors including the type of snow and how much it weighs, the structural design of your roof, and the material that your roof is constructed from, among other things.

The temperature, wind speed, and other factors can determine the type of precipitation covering your home. For example, wet snow can weigh up to three times more than dry, fluffy snow. This means that while a cubic foot of dry, powdery snow may weigh 5 pounds, that same amount of packed, wet snow will weigh closer to 15 lbs.

The architecture of your roof also affects how much snow your roof can handle. As a general rule, roofs that are built at an angle are typically more well-protected against snow than roofs that are flat. This is because angled roofs help divert precipitation better and are often able to withstand more weight.

The materials your roof is built from also have a huge impact on its resistance to snow. It’s important to choose a durable, high-quality roofing material like asphalt or slate shingles. Both options are great for supporting the weight of snow, but asphalt shingles are more affordable and easier to replace if needed.

Check Out Your Home and Be Prepared

If you want to get a good idea of the condition of your roof, the best place to look is indoors, in the attic. Check the rafters for any cracks or bends. If you see anything that looks problematic, keep in mind that it might not be an indication of a serious issue. There are many possible explanations for damaged rafters—for example, termites. And even if snow is to blame, you may be looking at damage from a previous winter.

If you’re concerned about potential issues with your roof, the best thing you can do is reach out to a licensed roofing professional for an evaluation.
