After a big snowstorm, the question comes up: should I clear my roof? The answer depends on several factors.
Understanding Snow Load
Not all snow weighs the same:
Fresh powder: ~3 lbs per square foot per foot of depthPacked snow: ~15 lbs per square foot per foot of depthIce: ~57 lbs per square foot per foot of depthMost residential roofs are designed to handle 30–40 lbs per square foot. That translates to roughly 3–4 feet of fresh snow — but only 6–8 inches of ice.
When to Be Concerned
Accumulation exceeds 2 feet of heavy, wet snowMultiple storms without thawing — layers compress and add weightRain on top of snow — dramatically increases weightVisible sagging in the rooflineInterior doors sticking or drywall cracking (signs of structural stress)Creaking sounds from the roof structureWhen You Can Wait
Light, fluffy snow under 2 feet on a modern, well-built roofSnow that's actively melting and running offYour roof has adequate pitch for natural sheddingSafe Removal Methods
Roof rake from the ground — the safest DIY option for single-story homesProfessional removal — recommended for multi-story homes, steep roofs, or heavy loadsNever use a shovel on your roof — you'll damage shingles and risk fallingImportant Safety Note
Every year, people are injured or killed falling from roofs during snow removal. If you can't safely reach with a ground-level roof rake, call a professional.
