For those that have owned a conservatory for a considerable number of years, the roof will naturally accumulate dirt over time. A reliable conservatory roof cleaner is a necessity to fully enjoy the benefits of the bright outdoors. Below is our guide to the 7 best conservatory roof cleaners, liquid and non-liquid. If you’re looking for something to battle the moss in your garden or roof panels, then we reviewed the best moss killers in this guide which may be more suited.

Without a clean roof, any sunlight that does make its way through will give a bleak and warped effect, dampening the ambiance that you’ve spent so many years creating. It gives a deflated feeling and edges you towards giving it the neglect you promised yourself you’d avoid.

Additionally, an unloved and dirty roof can actually cause a leak. The dirt in the roof may inadvertently cause the panels to slip in the gap sealing and cause damage. Though unlikely, is it really worth the risk?

We’ve included both liquid and non-liquid roof cleaners in the guide, necessary because lichens, moss, algae and mildew are living microscopic entities that need to be killed off with the chemical compounds in the cleaning agents. Another thing we looked at while considering the product is the environmental factors involved. 

We’ve ensured that all our products are ozone and eco friendly, ethically sourced, will not cause significant damage to the environment and that they are biodegradable. 

The guide also includes cleaning equipment. This list gives you the telescopic conservatory roof cleaners that are sort of brushes and brooms mounted on extendable poles that can be used to reach roofs without requiring a conservatory ladder. We also ensure that you can use them for other things that you find useful. We also wrote a guide on how to clean a conservatory roof, though below we investigate the 7 best conservatory roof cleaners on the web.
