As Owens Corning Preferred Contractors, HAAG Certified Inspectors, and Tamko Pro Certified Contractors, we offer expert advice and services to ensure your roof withstands the harshest conditions.
Understanding Snow Load and Its Impact
Fresh Snow
Fresh snow can accumulate rapidly, and its weight can accumulate. According to the Institute for Business & Home Safety (IBHS), 10-12 inches of new snow equals approximately one inch of water, or roughly 5 pounds per square foot of roof area. This suggests that you could accumulate up to 4 feet of new snow before weight becomes an issue.
Packed Snow
Compacted snow is denser and heavier than fresh snow. According to IBHS guidelines, 3-5 inches of old snow equals approximately one inch of water, or roughly 5 pounds per square foot of roof area. Accumulations exceeding 2 feet of old snow can pose significant risks.
Combined Snow and Ice
The total weight of accumulated snow and ice can be substantial. For instance, two feet of old snow combined with two feet of new snow could weigh as much as 60 pounds per square foot, approaching the design limits of even well-constructed roofs. Additionally, ice is much heavier, with one inch of ice equating to about a foot of fresh snow.
Roof Age and Material Considerations
The age and material of your roof play crucial roles in its ability to handle snow loads:
- Older Roofs: May suffer from corrosion and reduced capacity to bear heavy snow loads.
- Lightweight Roofs: Such as those made from metal, typically have less capacity to handle high snow loads.
- Flat Roofs: The step-down areas between roof sections collect ice and snow, posing additional risks.
How Much Weight Can Your Roof Handle?
Most roof designs can support at least 20 pounds per square foot. However, design loads in the Mid-Atlantic states can range from 10 to 20 pounds per square foot. Factors such as the roof’s condition and age are critical. It is essential to consult with a professional to assess your roof’s ability to withstand a harsh winter storm.
Preventive Measures
Regular Inspections
Schedule regular inspections to ensure your roof is in good condition before the winter season. Look for signs of wear and tear, and address any issues promptly.
Snow Removal
If snow accumulations become heavy, consider professional snow removal services to prevent excessive weight from damaging your roof. Be cautious when removing snow yourself to avoid causing damage.
Roof Repairs and Reinforcements
Ensure that any necessary repairs or reinforcements are completed before winter. This may include repairing leaks, reinforcing weak areas, and ensuring proper insulation.
