It’s important to waterproof a shed prolong its lifespan, as well as protecting the contents inside. If water gets in to your shed, it can create mould and mildew which can smell awful and cause irritation to your skin. The water can also rust your tools and equipment. Here we look at how to approach shed waterproofing.
If you’re looking at how to weatherproof a shed, you should look first at getting the right base. If your shed sits directly on to the ground, then moisture can easily enter, making it damp.
A simple wooden base will keep your shed from directly touching the ground and will allow air to circulate which helps to prevent rot. If you have a larger, heavier shed, a concrete base is advisable.
Wood naturally shrinks over time, and this can cause cracks in your windows and door frames allowing water to seep through. This can lead to rot and damage to your shed.
When waterproofing a garden shed, fill in cracks or gaps in your window and door frames with expanding foam. If you find signs of rot, you can dig it out with a screwdriver, fill in with a wood filler and then sand and paint to look as good as new. Remember to secure your shed door to keep water as well as intruders out.
Waterproofing a shed roof involves regularly clearing out the gutters. If leaves and debris block your shed gutters, then pools of water can collect on the shed roof making it more susceptible to a leak. If you don’t have gutters, it’s worth considering installing some as they will help solve drainage problems.
Your shed roof is the most exposed to the rain and elements and therefore needs careful attention when looking at how to waterproof a shed. Regularly inspect the weak points on your roof such as the edges and ridge lines, as well as where the roofing material is nailed down.
Felt will deteriorate over time; patch it to repair worn out spots or, when the time comes to replace the entire material, you opt for a shed waterproof membrane for the ultimate in shed waterproofing.

Finally – to waterproof garden sheds – don’t forget to ventilate! Airflow prevents the build-up of moisture which protects the longevity of your shed as well as its contents. Ventilate by opening the shed door and windows on milder days or by installing vents. Find out more about shed ventilation in our guide to preparing your shed for winter.
