Storm-Proof Your Trees Before MN Storm Season

The Twin Cities averages 3–5 severe wind events per summer with gusts over 60 mph. A $400 spring inspection prevents $5,000 in storm damage.

Spring checklist

1. Walk every tree

Look for:

• Dead branches over 2 inches in diameter pointed at the house, driveway, or play area.
• Co-dominant leaders (V-crotches) with included bark — major failure point.
• Cracks running along trunks or main limbs.
• Hollows or large cavities.
• Heaving root plates — soil lifted on one side of the trunk = the tree is starting to tip.
• Mushrooms at the base — internal decay, structural risk.
• Hangers (broken branches caught in the canopy) from winter ice.

2. Prune dead wood (the highest-ROI tree work)

A dead branch is a guaranteed missile in the next storm. Removing it costs $200–$600 per tree. Damage from one falling on a roof: $5,000–$50,000.

3. Cable weak unions

Co-dominant trunks with included bark fail in 50+ mph winds. Static cables ($400–$900 per cable) bind the leaders together — extends the tree's safe life by decades.

4. Reduce sail

For very tall trees with broad crowns near structures: a crown reduction or thinning (10–15% of canopy) reduces wind loading without harming the tree. Especially valuable on silver maple, willow, cottonwood, and large white pine.

5. Don't top

Topping creates weak regrowth that fails in 5–10 years. If a tree is too big for its spot, either reduce properly (drop-crotch cuts) or remove.

6. Identify removal candidates now

Trees you've been on the fence about: removing in May is 30% cheaper and 10x safer than removing the same tree from your roof in July.

Highest-risk species in the Twin Cities

• Silver maple — fast, brittle, drops big limbs.
• Cottonwood — huge, hollow at the core, drops 100-lb branches.
• Willow — soft, splits at unions.
• Boxelder — weak wood, frequent storm casualty.
• White pine — beautiful but tall and exposed; full crowns catch wind.
• Bradford pear — splits at the central union, period.

After a storm

• Stay clear of any tree on a power line — call 911 + Xcel Energy first.
• Photograph damage immediately for insurance.
• Tarp roof breaches before the next rain.
• Get a written estimate before signing anything (post-storm scams are constant).
• Verify contractor insurance — workers' comp + general liability.
