After a heavy Saskatchewan blizzard, it’s natural to look up at your roof and wonder: how much snow can a roof hold? As a local roofing company in Regina, we get this question all the time. The weight of snow is deceiving, and understanding the limits of your roof is key to keeping your home safe all winter long.
At Everflow, we’ve seen what our harsh winters can do. The good news is that most modern roofs are built to handle a typical snow load. However, not all snow is created equal. Let’s break down what you need to know.
It’s Not the Depth, It’s the Weight
The biggest mistake homeowners make is judging the danger of snow by its depth. The real factor is its weight, which is determined by moisture content.
A general rule of thumb is that one cubic foot of snow can weigh anywhere from 7 pounds (light snow) to over 20 pounds (heavy, wet snow).
How Much Snow is Too Much for Your Roof?
The exact roof snow load capacity depends on when your home was built and local building codes. Most modern homes in Canada are built to withstand a load of at least 35-40 pounds per square foot (psf).
So, how much snow can a roof hold in practical terms? Generally, a properly constructed roof should be able to support about two feet of fresh, dry snow or about one foot of heavy, wet snow.
If it rained or sleeted a lot and then got very cold, the danger is much higher. The type of roofing materials used can also play a role in how snow sheds or accumulates.
Warning Signs of a Stressed Roof
Your house will give you clues if the snow load is becoming too much. You should take immediate action if you notice any of these signs.
Inside Your Home
- Cracks in the Drywall: Look for new cracks appearing on interior walls or ceilings, especially around door frames.
- Sticking Doors: Interior doors that suddenly begin to stick or won’t latch properly can indicate the frame is being distorted by weight from above.
- Strange Noises: Popping, creaking, or groaning sounds are a serious red flag that the structure is under stress.
Outside Your Home
- Bowing or Sagging: A sagging roofline is the most obvious sign of heavy snow on a roof and requires immediate professional attention.
- Bent Gutters: Gutters and soffits that are bending or pulling away from the house are a sign of extreme weight from snow and ice dams.
- Water Leaks: If you see leaks or water stains on your ceiling, it could mean an ice dam has formed, which puts a heavy, concentrated load on the edge of your roof.
What Should You Do About Heavy Snow on Your Roof?
If you see any of the warning signs, the safest bet is to call a professional. Improperly removing snow can damage your shingles and, more importantly, pose a significant risk to your safety.
For homeowners looking for peace of mind, a professional inspection can ensure your roof is ready for winter. A trusted expert can assess your roof’s condition and provide advice for your specific situation. This is a core part of our roofing services in Regina.
While you’re checking your roof, it’s also a good time to inspect other parts of your home’s exterior, like your siding, to ensure everything is secure for the winter.
The Final Word on Snow Load: When in Doubt, Call a Pro
It’s time to consider snow removal when you have more than a foot of heavy, wet snow and ice accumulated. If you hear any strange noises or see your roof sagging, it’s an emergency.
