How Much Snow Can a Roof Hold?
Last Updated on 01/22/2024 by Matteo Lombardo

How much snow your roof can handle depends on how it’s built, what it’s made of, and the rules in your area. Most roofs can hold up to about 20 pounds of snow for every square foot.
Think of it like this: about four feet of new snow, two feet of old snow, or a mix of new and old snow up to two to three feet can all be about 20 pounds per square foot.
It’s important to keep an eye on how much snow is on your roof and clean it off when it gets too much. This helps stop damage like leaks or the roof breaking. You can use a special tool called a roof rake or get a professional to do it safely
What’s the Big Deal with Snow on Roofs?
Why Worry About Snow Load?
- Roofs Have Limits: Just like a backpack can only hold so many books, a roof can only support so much snow.
- Safety First: Too much snow can lead to leaks or, worse, a roof collapse.
How Much is Too Much?
- Rule of Thumb: Most roofs can handle about 20 pounds of snow per square foot.
- Type Matters: Fresh, fluffy snow weighs less than wet, packed snow.
Calculating Snow Load
- Simple Math: To figure out the snow load, multiply the depth of the snow in feet by the weight of a cubic foot of snow.
Warning Signs: Is Your Roof Crying for Help?
Indoor Warning Signs
- Cracks in the Rafters: Just like cracks in a vase, these are signs of stress.
- Door Frame Changes: Doors that stick or don’t close right can signal a shift in your home’s structure.
Outdoor Warning Signs
- Sagging Roofs: If your roof looks more like a hammock, that’s a red flag.
- Gutter Issues: Broken or clogged gutters are not just a nuisance; they hint at bigger problems.
