Polycarbonate conservatory roofs are much durable than their glass counterpart. Unlike tiles and glass panels, polycarbonate sheets will not crack or chip even in the long run.

However, they do come with some downsides of their own. If not cleaned regularly or professionally, such as by a team of expert conservatory cleaners in St Helens, polycarbonate sheets will become discoloured with the buildup of dirt and debris. And as such, your conservatory roof will become unpleasant to look at.

This article will show you all the steps you should follow when cleaning a polycarbonate conservatory roof. So keep reading to find out more.

Remove the Debris First

The first thing to do when cleaning your polycarbonate conservatory roof is to remove all the large pieces of debris. The debris may be in the form of sticks and leaves. So you can remove them by simply using any broom or maybe even a leaf blower.

But remember to be gentle when using the broom because it might damage the coating, which can cause leaks and scratches.

Check the gutters

Once you start washing or cleaning your conservatory roof, it is very likely for small dirt and debris to flow into your gutter. So make sure to detach your pipelines that go into the water collection unit before you start cleaning. This will prevent any damage to your filtration system.

Use Mild Soap or Detergent with Lukewarm Water

When washing your polycarbonate conservatory roof, make sure to use only a mild soap or a detergent powder along with lukewarm water. This will help remove the tough stains and dirt on your roof without causing any damage.

Strong detergents and soap with harsh chemicals have the tendency to damage the coating of your polycarbonate roof. And so you should avoid them at all costs. If you are not sure about the cleaning agents, then you can always ask the professionals for local St Helens driveway cleaning company.

Use Soft Sponges for Washing the Roof

Like hard detergents and soaps, rough sponges will also damage the outer coating of your polycarbonate roofs. Hence, you should always go for soft sponges to carefully clean the roof panels. You can clean by simply rubbing the sheets along the direction of the flutes.

Change the Water and Rinse the Sponge Regularly

If you keep using the dirty water to clean your conservatory, then your roof may end up looking messy from water spots. Also, scratches might appear on your polycarbonate roofs if there are any particles stuck on the sponge. Hence regular changing of water and rinsing of the sponge is an absolute necessity.

Check the Gutter Again

After you are done with the cleaning, make sure to check the gutter again before you reattach the pipes. Check if there is any debris or dirty water that can cause blockage or contaminate your stored water. You should also check for any leaks in the gutter system when you can.


Cleaning your polycarbonate conservatory is very easy and much simpler than a glass conservatory roof. All you have to do is remember to clean it regularly. Cleaning it at least once a year will be enough to keep it sparkling for the whole year.
