Winter in Maine is no joke. With heavy snowfall and icy conditions, one of the biggest concerns for homeowners is the accumulation of snow on roofs. Not only can this lead to structural damage, but it also poses safety risks. This guide will help you understand when and how to remove snow from your roof safely, incorporating guidelines from the State of Maine.
Why Snow Accumulation is a Problem
Heavy snow loads can stress your roof beyond its capacity, especially flat and low-pitched roofs commonly found in certain home designs and industrial buildings. Recognizing the warning signs of potential structural weaknesses is crucial to prevent damage or collapse.
How Much Snow is Too Much?
Understanding the weight of the snow on your roof is essential. Here are some general guidelines:
Fresh Snow: Approximately 10-12 inches of new snow equals about 5 pounds per square foot. Most roofs can handle up to 4 feet of fresh snow before becoming stressed.
Packed Snow: About 3-5 inches of old, packed snow equals the same 5 pounds per square foot. Therefore, 2 feetof packed snow could be problematic.
Ice: Just 1 inch of ice equals 1 foot of fresh snow, adding significant weight.
Example: A combination of 2 feet of old snow and 2 feet of new snow could weigh up to 60 pounds per square foot, exceeding the load capacity of many roofs.
Signs Your Roof May Be Stressed
Be on the lookout for:
Sagging sections
Severe leaks
Cracks in walls or masonry
Doors or windows that jam
Unusual creaking or popping sounds
If you notice any of these signs, evacuate the building and consult a professional immediately.
Safe Snow Removal Tips
Consider Hiring Professionals
Removing snow from roofs can be dangerous due to heights and slippery conditions. Professionals have the necessary equipment and experience.
If You Choose to DIY
Use a Roof Rake: Invest in a long-handled roof rake designed for snow removal.
Start from the Edge: Begin at the roof's edge and work your way up, removing small amounts at a time.
Avoid Damage: Leave a thin layer of snow (about 2-3 inches) to prevent damage to shingles.
Stay Grounded: Work from the ground if possible. Avoid climbing on ladders or the roof itself.
Watch for Falling Snow: Be aware of where the snow will fall to avoid injury.
Protect Yourself: Wear a hard hat and safety goggles.
What Not to Do
Don’t Use Open Flames: Never use torches or heat guns to melt snow or ice.
Avoid Electrical Devices: Keep electric heaters and hairdryers away from melting snow to prevent electrocution.
Stay Off the Roof: Walking on a snow-covered roof increases the risk of slips and falls.
Preventative Measures
Keep Gutters Clean: Clear gutters and downspouts to prevent ice dams.
Trim Overhanging Branches: Reduce the risk of additional snow falling onto your roof.
Improve Insulation: Proper attic insulation can minimize ice dams by keeping the roof surface cooler.
