How Much Snow Can My Roof Hold?

How Much Snow Can My Roof Hold?

On average, Detroit receives 45 inches of snowfall each year. The snow piles that you see on your lawn are also stacked up on your roof. A well-installed roof is fortified to handle the weight of snow, but every building has its breaking point. Let’s review how much snow your roof can hold to determine when you need to take action.  

Average Weight of Snow

Snow weighs approximately 20 pounds per cubic foot, which equates to about 1.25 pounds per inch. However, this number can vary considerably depending on the moisture content. Some snow is “wetter” than others, which adds to the pressure on your roof. If there is dense ice on the roof, that adds an extra 5 pounds per inch of snow.

How Much Weight a New Roof Can Hold

Your local building codes will dictate the minimum weight your roof is designed to hold. For instance, roofs in warmer climates may not have as strict weight requirements as colder climates where snow is more prominent. If you have an older roof or you did not use a licensed roofing company for installation, your roof may not meet the minimum weight-bearing requirements.

Older Roofs Are More Susceptible to Snow Damage

As your roof ages, the shingles lose their structural integrity. This is why we encourage homeowners to replace their roofs before they reach the very end of their lifespan. Otherwise, your home may be susceptible to water infiltration, wind damage, snow damage, and much more.

If your roof is at least ten years old, it’s probably time to schedule an evaluation. We can assess how many years your roof likely has left before you need to replace it, and we can help you take proactive measures to extend the life of your roofing.

How to Get Snow off Your Roof

If you’re worried about the weight of snow on your roof, you can take steps to cautiously remove it. One of the most common methods for getting snow off a roof is to use a snow rake. This is a special tool designed to pull snow down from the roof to the ground. You have to be careful about where the snow lands and where you orient yourself as you complete this process, but it can give your roof a break from the weight.
