Why the kind of snow matters

WVU Extension says two feet of dry, powdery snow on a flat surface weighs just under 10 pounds per square foot, while two feet of wet, dense snow weighs over 40. Drifts can pile more on one part of a roof. Steeper roofs generally carry less because snow slides off more easily. If you're building or replacing a shed roof, that's one reason pitch matters: how to build a shed roof.

Fall checklist (before the first storm)

1. Clear the gutters and downspouts. WVU Extension says to make sure they flow freely each fall and before big storms, to prevent ice buildup and drain meltwater.
2. Buy a roof rake now. WVU says to clear the eaves and as far up the roof as you can reach with a snow rake from the ground. If raking won't work for your shed, it says to line up a reputable company in the fall instead of at the last minute.
3. Look up for power lines. WVU and University of Minnesota Extension both warn to stay well clear of overhead power lines, since a rake can conduct electricity.
4. Check the anchors while the ground is still workable. How to anchor a shed.

Storing the mower and the gas can

The University of Colorado Boulder's fire safety rules for its own equipment sheds are written for a campus, not a backyard, but several points carry over:

• Keep plugs or caps on fuel containers to limit flammable vapors, and store them where they won't tip or spill and not next to the doorway.
• Gasoline vapor is heavier than air and collects low in a shed, which is why the rules call for low vents.
• Don't start motorized equipment inside unless two large doors at opposite ends are open.
• Hang a fire extinguisher where you can reach it on the way out, and keep the path out of the shed clear.
• Use approved fuel containers and keep the amount of stored gasoline as low as practical.

During and after a big snow

WVU Extension says to remove snow only when needed, because clearing it carries its own injury and roof-damage risk. University of Minnesota Extension says to go after the deepest snow first, and to avoid heavy scraping or chipping at ice, which can damage the roof and cause leaks.

Warning signs that a roof is overloaded include creaking, cracking or moaning sounds and bowing framing (WVU), or a roofline that's no longer straight (University of Minnesota). If you notice any of them, get out and stay out of the shed until the snow is gone.

Common questions

How much does snow on a roof weigh?

WVU Extension says two feet of dry, powdery snow weighs just under 10 pounds per square foot, while two feet of wet, dense snow weighs over 40 pounds per square foot.

Should I shovel snow off my shed roof?

WVU Extension says to remove snow only when needed and to use a snow rake from the ground. Don't climb onto a snowy roof unless you're a professional with proper safety equipment.

What are signs a shed roof has too much snow?

WVU Extension lists creaking, cracking or moaning sounds and bowing framing. University of Minnesota Extension adds a roofline that's no longer straight. Leave the building if you notice them.

How should I store gas in a shed over winter?

University of Colorado Boulder's shed rules say to keep caps on fuel containers, store them where they won't tip and not next to the door, use approved containers, and keep the amount as low as practical.
