Thankfully, we’ve put together this blog to help you prevent and resolve any condensation in your loft. So, read on for our helpful guide to avoid a disaster.

How to stop condensation in your loft

Condensation is caused by harsh weather conditions. As your roof takes the brunt of adverse weather such as snow and heavy rainfall, it’s more prone to wear and tear. The melting and refreezing cycle is also an issue, where ice forms in the eaves and causes moisture to move up the roof and seep into the attic, where condensation wreaks havoc.

How to stop condensation in your loft space

Step one: Regulate the temperature

In order to stop heat buildup that melts snow and triggers condensation, it’s important to regulate the temperature in your loft. This includes either:

• Ensuring appropriate ventilation
• Installing airtight insulation

Soffit vents are good for making sure fresh and cool air circulates your attic at all times, while foam insulation is perfect for attics that need a consistent temperature and airtight barrier.

Step two: Repair and maintain your gutters and downpipes

Damaged gutters and downpipes allow the walls on the outside of your house to get wet and cold, which is why ensuring they’re leak-proof and secure is imperative. If left unchecked, this could lead to penetrating damp that causes structural issues.

So, why not hire one of our professionals to come and maintain your gutters? You can see how much it might set you back here.

Step three: Ensure adequate airflow throughout your property

Make sure there’s always airflow through your home, such as your chimneys, vents, bricks etc. This will help avoid condensation build-up. Be sure to clean these regularly to stop dirt and dust blocking them and allowing moisture build-up.
