Preventing windstorm damage. Heavy winds and tornados are among the country's most damaging natural disasters. Although windstorms can occur at any time of year, they are most prevalent between June and September.1

What to do before the storm

Ensure your family's safety and prevent wind damage to your property and residence using these tips from our prevention advisors.


The roof of your home is usually the hardest hit by high winds. To limit damage, take the following precautions:

  • Make sure roofing components (fascia, soffits, chimney caps, etc.) are securely fastened so that the wind can't lift them.
  • Check that the roof is in good condition and repair any damage.
  • Make sure seals around chimneys, vents, skylights, dormers and other openings are in good condition.

Gutters and downspouts

Windstorms often come with heavy rain. To keep water from getting in:

  • Make sure the gutters are working properly and the downspouts are draining water well away from the foundation. You may need to add downspout extensions.

Windows and doors

  • Check that the doors and windows of the house, storage shed and garage are completely closed.

Outdoor contents

High winds can turn outdoor items into low-flying projectiles.

  • Make sure garbage cans, recycling bins, patio furniture, barbecues and any other items are properly stored and/or secured so that they don't blow away.
  • Remove the cover of your gazebo and close any awnings, if applicable.


  • Don't park your car near trees, street lights or power lines. If possible, park your car in a garage.

Propane tanks

If you have propane appliances, make sure you close the stop valve on the tank during a windstorm.

What to do after the storm

Once the storm has passed, here are a few tips to prevent any damage you may have sustained from becoming worse.

  • Secure the premises
    Pick up branches and other debris that could cause injury or damage.
  • Take the necessary steps to secure the property and prevent water damage2
    For example, board up broken windows.
  • Contact a tree pruner
    If you have a tree that is damaged or likely to fall and cause damage, call a professional.2
  • Contact a roofer if any repairs to the roof are needed2
