How to Clean Your Polycarbonate Roof

Polycarbonate conservatory roofs are renowned for their durability. Unlike glass panels or roof tiles, polycarbonate roofing sheets will not chip or crack throughout their lifetime. You may however notice a build-up of dirt and grime, or severe discoloration if you don’t clean the polycarbonate sheets often enough.

In this guide, we’ll be teaching you how to clean your polycarbonate conservatory roof, with steps you can use for any polycarbonate roof. We’ll reveal which soaps and tools you’ll need, as well as the most important times of year to show your conservatory roof a little tender loving care.

How Often Should You Clean Your Conservatory Roof?

Leaves, sticks and other forms of debris can build up on your roof over time throughout the year. This is especially true during the autumn and winter months when trees shed their summer leaves.

It’s because of this gradual build-up of debris that homeowners should clean their conservatory roof at least once a year. This is true whether your roof is made of glass panelling, roof tiles or polycarbonate sheets. This deep clean should reach every corner of your conservatory roof, from the panels to the glazing bars.

If your conservatory has a particularly low pitch, you’ll benefit from cleaning your polycarbonate roof twice a year. This is because low pitched roofs do not shed water or debris as easily as those with steeper pitches. So the build-up of debris and discoloration will occur at a noticeably faster rate.

How to Clear Your Polycarbonate Roof Sheets?

  1. Remove Any Large Debris

The first step is to remove large pieces of debris such as leaves and sticks. You can do this with a leaf blower or a household broom. Do ensure that you’re gentle enough not to pierce or scratch your polycarbonate panels, as this can damage the coating used to maximise their longevity or even cause leaks in future.

  1. Check Your Guttering

As you begin washing your conservatory roof, dirty water and small pieces of debris will flow into your guttering system. Be sure to clear your gutters beforehand and detach any water collection unit. This will save you time later and prevent any pressure being placed on filtration systems.

  1. Mix Mild Soap and Lukewarm Water

Strong detergents will damage the coating on your polycarbonate sheets, and should be avoided. Instead, use a mild soap that contains no harsh or abrasive chemicals. If you’re unsure, always contact the manufacturer. Mix this soap with lukewarm water to help break down tough dirt.

  1. Use a Soft Sponge to Wash Your Sheets

A rough sponge or scourer may damage the coatings on your polycarbonate sheets. You should therefore use a soft, gentle sponge to carefully clean your conservatory roof panels. Simply rub the sheets in the same direction as the flutes, which is usually vertical.

  1. Change Your Water and Rinse Your Sponge Regularly

Using dirty water will cause water spotting and may leave your polycarbonate roof looking messy. Make sure you change your water and rinse your sponge regularly while you’re cleaning your conservatory roof. Try to maintain the same mixture of soap and lukewarm water with each water change.

  1. Check Your Guttering, Again

It’s important to cast an eye over your guttering for a final time to ensure that no dirty water or debris have caused a blockage. This is also a great opportunity to make sure your guttering isn’t leaking anywhere. Don’t forget to reattach any water collection unit.

When Should I Replace My Polycarbonate Sheets?

With a life expectancy between 15 and 20 years, polycarbonate roofing sheets may need to be replaced on occasion. Failing to do so will interrupt light transmission into the space below and may lead to nightmare leaks. This could cause long-term damage to the roof and insides of your conservatory, so it’s best to keep on top of it.

In most circumstances, you needn’t worry about replacing your glazing bars. Instead, you may just need to replace the rubber gaskets that prevent water ingress, or the breather tape used along your polycarbonate roof panels.
