7 Ways to Waterproof a Storage Shed

Having a storage shed is a great way to store garden tools, outdoor equipment, and other belongings, but protecting it from water damage can be challenging. 

Keep your possessions safe from the elements with these seven ways to waterproof a storage shed.

Buy a Shed Made from Quality Materials

Waterproofing your storage shed starts even before it’s in your yard. When you are choosing a storage shed, be sure to look for one made from durable, water-resistant materials. Metal, plastic, or pressure-treated wood sheds are good options as they are more resistant to water damage compared to untreated wood sheds.

It’s also important that your storage shed is properly and professionally built as this will decrease the likelihood of gaps and cracks that could let in moisture.

Find the Right Location

Finding the right location for your storage shed can significantly reduce the risk of water damage. Ideally, choose a high-ground location to avoid water pooling around it during heavy rain. Ensure the ground slopes away from the shed to direct water away from the structure.

Likewise, try to keep your shed away from heavy plant life. Overhanging branches and dense foliage can trap moisture and increase the risk of leaks and mold. Plus, if your shed is surrounded by plants that need water to survive, you’re more likely to attract water to the base of your shed.

Treat with Waterproof Paint or Sealant

Waterproof paint or sealant is a great way to regularly waterproof a storage shed. Applying the paint or sealant to your shed's exterior creates a durable, water-resistant barrier. When using these, look for products designed for outdoor use and make sure to cover all surfaces, including walls, doors, and trim. 

Properly Seal Doors and Windows

Doors and windows are common entry points for water. Ensure they are properly sealed using weatherstripping or caulk. Over time, exposure to the elements can cause wood and plastic to warp, creating small gaps in doorframes and window sills. Regularly check for these gaps and reseal as necessary to prevent leaks.

Maintain Your Shed’s Roof

The roof is one of the most critical components in keeping your shed dry. Regularly inspect your roof for any signs of damage or wear. Environmental factors such as high winds, heavy precipitation, and falling tree branches can all create damage to your roof.

When deciding on a storage shed, choose one with a roofing material that offers good water resistance, such as asphalt shingles or metal roofing. It’s also important to ensure the storage shed has a roof style that works well with your environment. For example, a gable roof is better structured for areas with heavy snowfall than a gambrel roof.

Add and Maintain Gutters and Downspouts

Installing gutters and downspouts on your shed helps direct rainwater away from the structure. This prevents water from pooling around the base and seeping inside. If you have them already installed, be sure to regularly clean the gutters to ensure they function properly and replace any damaged sections promptly.

Ensure Proper Ventilation

Proper ventilation is essential for maintaining a dry shed. Install vents at the roof and eaves to allow air to circulate and prevent moisture buildup. Good ventilation reduces the risk of condensation and mold growth inside your shed.

By using these ways to waterproof a storage shed, you can ensure your storage space remains dry and your belongings are protected from the elements.
