How Do I Waterproof My Shed?

How Do I Waterproof My Shed?

Rachel Halladay

If you have a garden shed, you know that it's a highly versatile storage solution designed for outdoor use, and for the most part, they tend to do this role well. Occasionally, it may be necessary to go the extra mile to keep the interiors dry year round, especially when dealing with an older or improperly installed shed. 

If you're looking for a high-quality timber for your garden, BTL Timber has a wide selection available to choose from for customers across the North East. While we aren't concerned with our sheds leaking, it's always handy to know that waterproofing can be done yourself, and can provide your shed with a longer life. Now, keep reading below for our top tips on waterproofing your shed. 

What Are The Benefits Of Waterproofing My Shed?

There are many reasons why you may decide to waterproof your shed if you notice water leaking through. While there are many good reasons, we have highlighted some of our favourite, including: 

Aesthetics: Sitting water can strip away paint and stain wood, leaving your timber shed looking shabby and unkempt. Waterproofing is a great way to ensure your shed stays looking as good as new for years to come. 

Shortened Life Span: Sheds are designed for outdoor use, so they are highly resilient to the Great British weather, but long periods of wet weather that results in leaks can significantly shorten the lifespan of your shed. 

Retain Function: Sheds are perfect for keeping tools and equipment stored inside, but if water is getting in then the shed isn't doing it's job and certain electrical equipment can become damaged and stop working. 

At BTL Timber, we are reputable timber merchants offering a wide range of quality timber supplies across the North East, and our sheds are popular with customers from Bishop Auckland, to Darlington, and beyond.

Wood Treatment or Sealant

Treating your shed's wood with a high-quality sealant is one of the most effective ways to protect it from moisture. A good wood treatment, whether oil-based or water-based, penetrates the wood fibres, creating a barrier that prevents water from seeping in and causing rot or decay. It also helps to protect the wood from UV damage, which can lead to warping and discolouration over time. For best results, apply a sealant at least once a year, focusing on areas most exposed to the elements, like the roof, walls, and any exposed joints. This simple maintenance step can significantly extend the lifespan of your shed, ensuring it remains sturdy and visually appealing for years to come.

Waterproof Roofing

The roof is your shed's first line of defence against rain, so ensuring it is properly waterproofed is essential and goes a long way towards the overall maintenance of your shed. There are several options available for waterproof roofing, including rubber roofing (such as EPDM), roofing felt, and shingles. EPDM rubber is highly durable and flexible, offering superior water resistance and longevity, while roofing felt is a more affordable option that still provides decent protection against the elements. Shingles, on the other hand, not only add a traditional aesthetic but also help in shedding water effectively. Whichever material you choose, ensure that it is properly installed with no gaps or weak points, and regularly inspect your roof for signs of wear or damage, especially after heavy storms.

Caulk Windows and Doors

Water can easily seep through small gaps around windows and doors, so caulking these areas is crucial to keeping your shed dry. Use a high-quality outdoor silicone caulk, which is flexible and waterproof, to seal any potential gaps around the frames of windows and doors. When applying caulk, ensure the surface is clean and dry to allow for a proper seal. This step not only prevents leaks but also helps with insulation, keeping the inside of your shed warmer and reducing the risk of dampness and mould growth. Regularly check the caulking for cracks or peeling and reapply as needed to maintain an effective barrier against water.

Raise the Shed Off the Ground

Raising your shed off the ground is another effective method for waterproofing, as it prevents moisture from the ground from seeping into the base. Over time, water from rainfall or damp soil can lead to wood rot or create mould issues, especially in areas with poor drainage. To avoid this, elevate your shed using materials like concrete blocks, treated wood beams, or even metal supports. This will not only keep the shed's base dry but also allow for better air circulation underneath, further protecting it from moisture buildup. A solid foundation can add years to the life of your shed and help ensure it remains functional and in good condition through all seasons.
