Here at Easy Frame we know a conservatory is one of the nicest and low maintenance rooms to have in your house. They let in so much light and can be incredibly peaceful rooms. However, because of the glass roof of a conservatory, they can become quite dirty. And once they’re dirty it compromises some of the wonderful natural light coming in.


Preparation for cleaning

The first thing with any cleaning project is to make sure that you’re fully prepared. When it comes to cleaning a conservatory roof, you will need to decide how you’re going to access it. Obviously standing on a conservatory roof isn’t a good idea, especially if the roof’s made of glass. You could crack a panel and end up having to replace the roof!

Access - Three Choices


  • Use an extendable brush and do it from the ground. (best option)
  • Use a step ladder to get up to the roof and lean over. (not recommended)
  • Buy a conservatory ladder designed to do the job. (best for professionals)


If you choose to clean it from the ground like some window cleaners then you will need a long tool which will allow you to reach the entire roof effectively. You’ll also need to consider several other products that will help you get your conservatory roof in tip-top shape.
