If you’ve spent hours grafting away making your roof perfect only to discover condensation starting to creep in, you’ll probably feel quite annoyed. All the hours of hard work up a ladder – and for what?

Exposed to the elements day in and out, condensation can start to build up on your roofing sheets, leading to damage, rust and corrosion. But it doesn’t have to be that way. With a little care and attention, you can ensure that your roof lasts for years to come.

What causes condensation on roofing sheets?

If you find yourself wondering why your roof seems to be a condensation party, you’re not alone.

Roof condensation occurs purely because the temperatures on the inside and outside of your home or garage are different. When warm air collides with cold surfaces, water droplets from the warm air are cooled. This is what we call condensation.

Ever wondered why winter seems to be the time of year when condensation rears its head? Simply put: the condensation that you find on your roofing sheets is more prominent in winter due to the cooler outdoor temperatures.

What problems does condensation cause for your roofing sheets?

Although you might think “what harm can a little water do?”, condensation can wreak havoc on your roofing sheets.

The wet and warm conditions inside your home or outhouse can, over time, become a breeding ground for mould, mildew and bacteria. Left untreated, this can actually have some pretty nasty consequences for you and your family – especially if you live with asthma or allergy sufferers.

Aside from being bad for your health, condensation can also affect the performance of your roof. A faulty roof can lead to heat escaping which can, in turn, increase your energy bills – neither of which is good for your bank account or the pla


If you have steel roof sheets, things can become even more severe. The components in metal roofing sheets can corrode over time when exposed to water. Not only does this rust mean that you’ll need to replace your roofing sheets sooner but you may also experience some damage to your home if your roof isn’t performing optimally.

How to prevent condensation on your roofing sheets

If you’ve fallen victim to moisture within your corrugated roofing, chances are that you’ve got a condensation problem.

Luckily, there are a few things that you can do to keep condensation at bay.

Control moisture

For condensation to occur, there must be moisture in the air. Therefore, one easy way to combat condensation is to control the moisture levels in your home, shed, outhouse or office. Although it’s not reasonable – or even possible – to eliminate moisture entirely, you can reduce condensation by allowing proper ventilation.

Opening windows for a few minutes and using fans can go a long way to circulate the air and allow moisture an escape route.


As well as opening windows, another way in which you can increase the ventilation in your home is by adding ventilation holes. By doing this, you give moisture and warm air a place through which to escape, saving your roof from the wrath of condensation.

Correct insulation

As we’ve established, condensation is formed when warm air meets cool air. One way to ensure that warm air doesn’t fully reach your roof is by installing insulation. By creating a barrier between the cold underside of your roof and your home, you’ll be able to vastly reduce the amount of condensation that gathers.

What’s more, by choosing insulated roofing sheets, you’ll also be able to keep your home toasty-warm!

Choosing the correct pitch and corrugations

One way to slash your chances of falling victim to condensation is by choosing the right pitch and corrugations. Typically, the bigger the corrugations, the more chance that you have of developing condensation. This is because it is harder for excess water to run off.

The same goes for your roof pitch. By choosing a higher pitch, you’ll give the water more of a chance to run off, diffusing any humidity.

Invest in a dehumidifier

If you’re serious about tackling condensation head-on, then a dehumidifier could be a worthwhile investment.

Dehumidifiers work by drawing in warm air and allowing the condensation to collect into its water tank. The cool, moisture-free air is then released back into the atmosphere like normal. This way, once the air reaches your roof, there is very little moisture to collect – so very little chance for condensation to build up!

Use anti-condensation paint

One of the easiest and cheapest ways to fix condensation is with anti-condensation paint. Designed for small areas of condensation, the paint works by adding what’s called an elastomeric coating to prevent damp from getting to your roof.

Because the paint is so thick, it can also help to insulate your home!
