Polycarbonate roofs, often found on conservatories and outdoor structures, are a popular choice of roof due to their durability and light-transmitting qualities. However, over time, dirt, debris, and algae can build on the surface, affecting both the appearance and performance of the roof.
In this guide, we’ll explore the best methods for cleaning a polycarbonate roof to keep it in top condition, ensuring it remains clear and functional.
When to clean your conservatory roof
The best time to clean your polycarbonate roof is during mild weather, ideally in the spring or early autumn, when temperatures aren’t too hot or cold. This ensures that the cleaning solution won’t dry too quickly and won’t freeze, providing optimal conditions for a thorough clean.
It’s also a good idea to clean your conservatory roof at least twice a year to remove debris and prevent buildup of dirt and algae. However, if you live in an area with lots of trees, you may need to clean more frequently to remove leaves and branches.
Safety considerations
Before you begin cleaning your polycarbonate roof, it’s important to keep safety in mind by following these steps:
- Use a stable ladder
Ensure that you use a sturdy ladder when accessing the roof and place it close to the area you’re working on to prevent over reaching. Keep it at a 75 degree angle and ensure someone is holding it down.
- Avoid walking on the roof
Polycarbonate panels are strong, but not designed to support human weight. Use a roof ladder or board to distribute your weight if necessary.
- Wear protective gear
Gloves, non-slip shoes, and safety goggles can help protect you during the cleaning process.
- Check the weather
Avoid cleaning your roof on windy or rainy days to reduce the risk of slips and falls.
Tools for the job
The following is a list of the roofing tools you’ll need to effectively clean a polycarbonate roof:
- Soft-bristle broom or brush
- Garden hose with spray attachment
- Bucket
- Mild detergent or specialised conservatory roof cleaner
- Soft sponge or cloth
- Microfiber cloth
- Ladder (with stabiliser)
- Gutter scoop or trowel
Step by step guide: cleaning a polycarbonate roof
Step one: sweep debris
The first step in cleaning a polycarbonate roof is to remove any debris, such as leaves, branches, or dirt, from the surface. Use a soft-bristle broom or brush to gently sweep away the debris, ensuring not to scratch the surface of the roof.
Step two: clear gutters
Next, clear out any debris that may have built up in the gutters around the roof. Use a gutter scoop or trowel to remove leaves and dirt, so that water can flow through the drainage system. This will prevent water buildup that could damage your roof over time.
Step three: create a soapy solution
In a bucket, mix a solution of warm water and a mild detergent. Alternatively, you can use a specialist conservatory roof cleaner that’s designed for polycarbonate surfaces. Avoid harsh chemicals or abrasive cleaners, as they can damage the roof’s surface.
Step four: clean the roof
Using a soft sponge or cloth, gently scrub the polycarbonate roof with the soapy solution. Start from the top and work your way down to ensure that dirt and water are washed away as you clean. For tough spots, use a bit of extra elbow grease but avoid using abrasive materials that could scratch the surface.
For areas that are hard to reach, use a long-handled soft brush or mop. Once the entire roof is clean, use a garden hose to rinse off the soap and grime. Ensure that all cleaning solutions are thoroughly rinsed to avoid streaks or residue.
Step five: final checks
After cleaning, do a final inspection of the roof to ensure that all areas are clean and free of debris. Look for any signs of damage, such as cracks or leaks, which may need to be addressed. Dry the roof with a microfiber cloth if necessary to prevent water spots.
How to clean the inside of a polycarbonate roof
Cleaning the inside of a polycarbonate roof is just as important as cleaning the exterior. Dust, cobwebs, and condensation stains can build up inside, especially in conservatories.
Start by dusting the surface. Use a soft cloth or duster to remove any dust or cobwebs. Similarly to the exterior cleaning process, mix a mild detergent with warm water in a bucket.
Gently clean the inside of the roof using a soft sponge or cloth, being careful not to apply too much pressure. Finally, dry the interior thoroughly using a microfiber cloth on the surface, ensuring there are no streaks or watermarks left.
How to get algae off a polycarbonate roof
Algae can be a common problem on polycarbonate roofs, especially in damp or shaded areas. To remove algae from your polycarbonate roof, follow these steps:
- Apply a mild cleaning solution: use a specialised cleaner for removing algae or mix a solution of water and white vinegar.
- Scrub gently: using a soft brush, gently scrub the affected areas to lift the algae. Be cautious not to damage the roof's surface.
- Rinse thoroughly: once the algae is removed, rinse the roof with a hose to remove any leftover solution.
Regularly cleaning your roof and preventing moisture buildup can help avoid algae growth in the future.
Can you pressure wash a polycarbonate roof?
It’s not recommended to pressure wash a polycarbonate roof, as the high-pressure water stream can damage the surface and cause cracks.
Instead, use a garden hose with a spray attachment to rinse the roof gently. If you’re dealing with stubborn dirt or stains, a soft sponge and cleaning solution will usually do the trick without the need for high pressure.
How to replace polycarbonate roof panels
If your polycarbonate roof has sustained damage, such as cracks or significant wear, you may need to replace individual panels. Below is a brief overview of the process:
- Assess the damage: identify which panels need to be replaced and measure their size.
- Remove the damaged panels: carefully unscrew or unclip the damaged panels from the roof frame.
- Install new panels: place the new panels in position and secure them with screws or clips, ensuring a watertight fit.
- Seal the edges: use a silicone sealant to seal the edges of the panels and prevent leaks.
Signs you need to replace your roof
Over time, polycarbonate roofs can show signs of wear that indicate the need for replacement. Therefore, you should watch out for the following:
- Cracks or holes: Visible damage that enables water to enter the structure.
- Discoloration: Yellowing or fogging that reduces light transmission.
- Leaking or pooling water: Persistent leaks that can’t be fixed with simple repairs.
If you notice any of these issues, it may be time to consider replacing your roof. Eurocell offers durable and high-quality polycarbonate roofing products that are designed to last, providing excellent light transmission and protection.
