We look specifically at average annual rainfall followed by the top rainfall events over the past five years. We’ll also touch on what you can do to protect your home from heavy rain damage.

How to Protect Your Home from Rain 

The lists above show that Missouri gets plenty of rain on average as well as an all-too-impressive amount during heavy rainfall and storms. That makes it important to make sure your home is protected.

Here are our recommendations of things to consider in protecting your home.

  • Gutters and downspouts. Your gutters and downspouts need to be sized adequately to carry the water that runs off your roof. Make sure to remove leaves and clear obstructions as well as repair any damage. See our article Calculating the Importance of Gutters and Drainage for more information.
  • Downspout extensions. These serve to take the water from the downspouts and route it well away from your home’s foundation. You don’t want water collecting around the walls of your basement or crawl space trying to find cracks or openings.
  • Landscaping. Grade the soil around your foundation to allow water to flow away from the foundation. When water runs off the roof, into gutters, and downspouts, it will then continue its journey away from your basement or crawl space.
  • Clay bowl effect. The soil surrounding your foundation has a different drainage factor than the surrounding soil. During construction, the soil was excavated, the foundation built, and then the soil was replaced. So it is loose, and as a result, it allows water to flow toward the basement or crawl space. It essentially forms a bowl that gathers water around the foundation.
  • Waterproofing. Inspect your foundation carefully and fix any basement or crawl space cracks as well as any openings for pipes and drain lines. Install an interior drainage system and sump pump to collect and remove leaks before they become flooding problems.

As you can tell, rainwater can find its way into your basement or crawl space, whether it’s a gentle rain or one of the torrential rainfalls we’ve listed above. 

We recommend that you consult the professionals at Foundation Recovery Systems for a free inspection and repair estimate to identify any issues with your basement or crawl space that need attention in preparation for heavy rains.
