Is Your Garden Building Leaking? Here Are Reasons Why That Might Be!

British weather is known across the world for being notoriously wet. On average, it rains for 29 per cent of days per year and rainfalls can be extremely unpredictable. This means that garden shed leaks can be a major issue in our outdoor structures.

Our experts have recognised this problem and have determined the root causes of leaking outdoor building roofs, walls, and floors! Here are the possible causes of leaks in your garden structure and how to combat them:

1. Incorrect assembly causing shed leaks

When assembly instructions aren’t strictly followed, there could be some hidden issues in your garden buildings. When the rain starts to pour, this can take a toll. This is because there can be some gaps left in-between pieces that cause garden shed leaks.

To combat this, you can use wood fillers to fill in the gaps. You can also nail thin battens over the gaps in your building’s exterior. To avoid this problem early in the installation, on the other hand, make sure to read our assembly manual carefully. We have provided some instructions in dealing with such an issue.

2. Not laying the felt or roof covering correctly

Roof felt or other roof coverings in garden buildings act as a waterproof layer to protect underlying shingles and other roofing materials. Once it is wrongly attached, water and other elements can reach the roof and cause damage and garden shed leaks.

To avoid this, lay your roof felt properly and check for any disparity before finalising its attachment. You should also only add it after properly cleaning and drying your structure’s roof.

3. Contraction and expansion of wood

Contraction and expansion within the wood are inevitable, as relative humidity can affect its moisture content and cause wood to shrink or expand. When this happens, gaps can appear in some parts of your wooden garden building which weren’t originally there.

One of the best ways to resolve contraction among tongue and groove pieces is to simply fit them back together. You can remove the screw on the affected part and hammer them together using another chunk of wood. You can then screw them back once the gap has been closed.

4. Not following our care guide

In every garden building kit, BillyOh provides a detailed assembly manual that includes important installation tips, guide in dealing with a possible blemish in wood, and a maintenance checklist.

The list includes enabling clear access to all sides of the building during construction and having a clear 2ft boundary around its perimeter when installed. These tips are essential as overhanging hedges or trees may pierce the roofing felt or glazing and would allow water ingress.

Check out a sample of our garden buildings’ detailed manuals for more information and tips.

5. Not having a durable base

A wooden shed is not going to last long if it doesn’t sit on a nice stable base that is off the ground. If it is directly installed on the ground, water can easily enter the structure and cause floor leaks. Even metal and plastic sheds benefit from some sort of base in the long run.

If this is the case, you will have to create a proper foundation for your garden building. You can choose between an eze, concrete, or paving slab for your structure’s base.

6. Clogged guttering

Gutters in garden buildings can become clogged with pine needles, leaves, branches, and other debris. Since gutters are meant to help draw water away from the roof, blockage makes them instead pool and can lead to garden shed leaks.

You can simply combat this problem by using a ladder and cleaning out your gutters. For easy disposal, you can place a large tarp underneath the area where you are working, drop the debris, and dispose of it easily afterwards.

Experts recommend cleaning your structure’s gutters at least twice a year. But, if you live in a property surrounded by a lot of trees, you should remove debris from your gutters three to four times every year.

If your garden building has no guttering system, you are required to install one to deter rainy day problems. Many of our garden sheds come in built-in guttering options and efficient drainage systems.

7. Not treating the building fully or properly

If you have a wooden garden building and have not treated it yet, there is a higher probability of moisture coming straight through the weatherboard. This means that you have to treat the structure fully, properly, and on a regular basis to protect your wood.

You can also consider painting it is as it is one of the best maintenance techniques you can apply to protect your garden building from moisture. Most of BillyOh’s garden building designs come in a pressure-treated option that cuts out the need to treat it regularly.

8. Worn out roof

Over time, garden building roofs age and become worn out due to harsh weather conditions and exposure to sunlight. This problem makes it easier for water to sneak in. You can combat this issue through proper maintenance, repairing any damage in your roof as soon as you notice it.

However, if the roof of your outdoor structure has been totally run-down, you may have to re-install another. You can also purchase a new sturdy and durable garden building which can be a greater long-term investment.

9.  Ice dam buildup

An ice dam is a ridge of ice that forms at the edge of a roof. It happens in homes and it can happen in garden structures as well, especially among apex roofs. When the snow melts, it can drain off into your roof and damage it, causing shed leaks. The weight of the ice can also damage the roof, aside from the water sitting on its surface.

To get rid of this problem, you can invest in a roof rake. It looks like a sideways shovel with a long handle used to reach up onto the roof and remove snow from the edge. You can also do this manually to prevent ice dams from forming. Ice melt products can also help combat this winter issue.

10. Spaces in the joints

Depending on age, some of your garden structure’s joints might have broken down. You can find these joint spaces in roofs, doors, window strips, window sills, and corners. If that’s the case, you can pop them off and put some new sealing before you put them back on.

If they are some tiny holes and breaks, you can simply use some weather sealant to close them to prevent garden shed leaks.
