With its visual attractiveness and versatility, a conservatory is a place where you can escape, connect with nature, and experience the changing seasons from the perfect vantage point within your own home.

However, conservatory roofs can accumulate dirt, grime, and even moss over time, lessening their allure.

We will guide you through the process of cleaning your conservatory roof, talk about the best methods to clean each type of roof and ensure you regain its appeal, so it continues to be a welcoming oasis in your home.

So, whether you have a glass, polycarbonate, tiled or plastic roof on your conservatory, read on to find out how to clean a conservatory roof and keep it looking its best. 

 

How often should a conservatory roof be cleaned?

Regular cleaning of your conservatory roof is important to maintain its appearance and functionality. The question of how often you should clean depends on several factors, including the surrounding environment, the type of roof material, and the weather conditions in your area. 

For example, there are a number of things that are problematic with polycarbonate roofing. It is more vulnerable to chemical reactions, and chemical deposits often lead to discolouration or corrosion, so, therefore, you may have to clean it more frequently than a conservatory with solid roofing materials, which are less affected by these things.

If you’re in an area with heavy rain, it can carry dirt and debris from the air or nearby trees onto the roof. As the rainwater flows down the roof’s surface, it can leave behind streaks and stains. Glass roofing in particular is known for suffering from water streaks, especially if they haven’t been cleaned regularly. It can be frustrating when a buildup of dirt and debris is washed down by the rain, creating stains and marks.

Additionally, if the conservatory roof doesn’t have proper drainage systems, rainwater can pool in certain areas. This pooled water can collect dirt and debris, leaving behind a grimy residue.

To maintain a clean and attractive conservatory roof in these conditions, you will require proper cleaning methods, including the use of appropriate cleaning solutions and equipment. This can help prevent the harmful effects of pollution and rainfall on the roof’s appearance. As a general guideline, here’s what you need to do to keep your conservatory roof clean.

Monthly

In areas that suffer from high pollution, are surrounded by trees, or have frequent rainfall, monthly cleaning may be necessary to prevent the buildup of dirt and debris. 

High pollution, surrounding trees and excessive rainfall can contribute to the dirtiness of a conservatory roof in several ways:

  • Airborne particles: Pollution in the form of airborne particles, like dust and pollen, can settle on the conservatory roof. Over time, these particles accumulate, creating a layer of grime.
  • Chemical deposits: Some pollutants contain chemicals that, when combined with rain, can form acidic compounds. These compounds can react with the materials on the conservatory roof, potentially causing staining or corrosion.
  • Moss and algae growth: Excessive rainfall can create a moist environment on the roof, especially in shaded areas. This moisture can encourage the growth of moss, algae, or mildew, which can make the roof appear dirty and discoloured.

Quarterly

Even in moderately clean environments like suburban neighbourhoods, cleaning every three months should provide a basic level of maintenance. Cleaning quarterly will ensure that debris and contaminants which could damage the roofing material are cleared.

If you have a glass roof, you may want to clean it more regularly to ensure you’re receiving the best energy efficiency (dirty glass can prevent your conservatory from getting warm), keeping up aesthetics and maintaining a clear view to let natural light through, and to prevent staining.

Semi-Annually

For conservatories in very clean, rural areas or in regions with mild climates, cleaning the roof every six months may be adequate. However, it is not recommended for all roof types. This would be best suited to more resilient, low-maintenance roof materials like tiles and roof panels.

Annually

Conservatories with more hardy roofing materials, such as UPVC, in exceptionally clean and dry locations may only require annual cleaning to refresh your conservatory and maintain a clean appearance.

It’s essential to adjust the cleaning frequency based on your conservatory’s unique conditions.

 

Tools for cleaning a conservatory roof

Before you begin cleaning your conservatory roof, gather the necessary tools and equipment to make the process efficient and safe. Here are the essential tools you’ll need:

Cleaning Products

Mild detergent or conservatory cleaning solution: These products can effectively remove dirt, grime, and other contaminants from your conservatory roof. Be sure to choose a solution that is suitable for the specific roofing material you have.

Warm water: Using warm water helps to dissolve and rinse away dirt and cleaning solution residues. It will work far more effectively than cold water. 

Soft brush or mop: A soft-bristle brush or mop is used to scrub the roof gently. Make sure the brush or mop is non-abrasive to avoid scratching or damaging the roofing material.

Bucket for mixing the cleaning Solution: You’ll need a bucket to mix the mild detergent or conservatory cleaning solution with warm water. Follow the product’s instructions for the appropriate dilution ratio.

Telescopic Brush

A telescopic brush with soft bristles is a vital tool for cleaning hard-to-reach areas of your conservatory roof. It is perfect for cleaning roof panels, glass and other roof materials but can also be used for windows, gutters and frames. 

This allows you to extend your reach and safely clean without the need for ladders or scaffolding.

Conservatory Ladder

If your conservatory roof requires additional access, invest in a conservatory ladder designed specifically for this purpose. Safety should be a top priority when using ladders, so make sure it’s the right height and stable.

Pressure washer

A pressure washer can be a great tool for cleaning glass, plastic, tile or polycarbonate roofs, provided you use it on a low-pressure setting. It helps to remove stubborn dirt and clear grime that would not be removed with a regular hose. Be cautious not to damage the roof with excessive pressure, as this can affect the seal and coating. 

Moss killer

In cases where moss or algae have taken hold on your roof, common with many polycarbonate roofs, a moss killer or algae remover can be a valuable addition to your cleaning equipment. Follow the product’s instructions carefully to ensure safe and effective removal.

 

How to clean a conservatory roof: A step-by-step guide to the different types

Knowing how to clean a conservatory roof depends on what type of conservatory it is, the roofing material and your surrounding environment. 

The type of material your conservatory roof is made of will determine the cleaning approach. Here are the methods for cleaning different types of conservatory roofs:

How to Clean a Glass Conservatory Roof

Step 1: Clear debris

Begin the process by removing any loose debris, twigs or leaves from the roof’s surface. A soft brush or mop is suitable for this task.

Step 2: Mix cleaning solution

In a bucket, mix a mild detergent or conservatory cleaning solution with warm water. Use the detergent guidelines to get accurate measures. 

Step 3: Apply cleaning solution

Using your telescopic brush or a soft mop, apply the cleaning solution to the glass roof. Start from the top and work your way down to prevent streaks.

Step 4: Scrub gently

Gently scrub the surface to remove dirt and grime. Pay special attention to any stubborn spots.

Step 5: Rinse

Use your pressure washer on a low-pressure setting or clean water to rinse the roof thoroughly.

Step 6: Dry and buff

After rinsing, dry the roof with a clean, lint-free cloth to prevent water spots. Buff the glass to get a sparkling finish.

How to Clean a Plastic Conservatory Roof

Step 1: Debris removal

As with the glass roof, thoroughly clear any loose debris from the plastic roof’s surface, ensuring a clean starting point for the cleaning process.

Step 2: Prepare cleaning solution

In a suitable container, combine a mild detergent or a specialised conservatory cleaning solution with warm water. Ensure the solution is well-mixed and ready for application.

Step 3: Applying solution

Using a telescopic brush or a soft mop, evenly apply the prepared cleaning solution onto the plastic roof’s surface. This step is crucial for loosening and dissolving various forms of dirt and stains.

Step 4: Gentle scour

Carefully and gently scour the roof’s surface to remove accumulated dirt and grime. It is important to avoid applying too much pressure, as this may lead to nasty scratches on the plastic material.

Step 5: Rinse

After effectively cleaning the plastic conservatory roof, rinse it thoroughly with clean water to ensure the complete removal of the cleaning solution and any remaining contaminants.

How to Clean a Polycarbonate Conservatory Roof

Step 1: Clearing

Begin by eliminating any loose debris from the surface of the polycarbonate roof. Pay particular attention to this step to ensure a clean starting point for the cleaning process.

Step 2: Prepare and apply the cleaning solution

Using a bucket, prepare a cleaning solution with warm water. Use a telescopic brush or a soft mop to evenly apply the prepared cleaning solution to the polycarbonate roof. Polycarbonate roofs are more delicate than glass, so it’s crucial to use a suitable cleaning solution for this material.

Step 3: Gentle scrubbing

Gently scrub the surface to remove dirt. Take extra caution not to use excessive pressure, as polycarbonate is also prone to scratching and damage if mishandled.

Step 4: Attention to mould

Polycarbonate roofs can be susceptible to mould and algae growth due to their porous nature. If mould is present, consider using a mildew or mould remover as part of your cleaning solution and ensure thorough cleaning to prevent future growth.

Step 5: Thorough rinsing

After effectively cleaning the polycarbonate conservatory roof, rinse it thoroughly with clean water. This step is essential to remove any cleaning solution residue and prevent potential damage to the polycarbonate material.

How to Clean Conservatory Windows, Frames, and Insides

When it comes to cleaning your conservatory, it’s important to pay special attention to the windows, frames, and interior. 

These areas not only contribute to the aesthetic appeal but also affect the overall comfort of your conservatory. Here’s how to achieve a clean and well-maintained conservatory:

  • After removing any debris or dirt that may have been collected on the window, clean the glass windows using the same cleaning solution and techniques used for the roof. Remember, warm water will work best on stains.
  • Wipe down the window frames and sills with a damp cloth and a mild detergent if necessary. It is very common for badly insulated conservatories, or those which experience extreme changes in temperature, to suffer from condensation problems. Condensation can then lead to mould gathering on the walls and ledges.
  • Vacuum or sweep the interior of the conservatory to remove any dust or dirt. Keep an eye on blinds and curtains to check dust isn’t building up. Wipe down surfaces with a clean, damp cloth to keep things looking fresh.
