Maintenance Tips for Polycarbonate Roofs
Polycarbonate roofs are a popular choice for conservatories, greenhouses, and other structures requiring durable, lightweight and transparent materials. However, like any building materials, they need proper maintenance to ensure longevity and performance. This guide will provide you with essential maintenance tips to keep your polycarbonate roof sheets in top condition.
Summary
This guide covers how to keep polycarbonate roofs performing well: clean regularly with soft materials and mild detergents, then rinse and dry to maintain clarity. Inspect frequently for cracks, leaks and loose fasteners, repairing small issues promptly and resealing joints as needed. Protect against extreme bracing, UV-protected sheets, and snow/ice removal, and prevent algae or mould through routine cleaning, good ventilation, and suitable inhibitors.
The polycarbonate roof sheets are made from strong thermoplastic material known for its impact resistance and transparency. These sheets are ideal for a variety of application, including conservatory roofs, greenhouses, and commercial buildings. They are available in various thickness and can be clear or tinted to specific needs.
Polycarbonate sheets are know for their thermal insulation, UV protection and how lightweight they are. However if you have a conservatory and are looking to use it more all year round insulating your conservatory with a multi-foil insulation system will transform in into a more useable room all year round. to find out more on this click here.
Regular cleaning

Regular cleaning is crucial to maintain the clarity and appearance of your polycarbonate roof. Dust, dirt, and debris can accumulate over time, affecting both aesthetics and performance.
Steps for cleaning your polycarbonate roof:
- Use soft materials: Always use a soft sponge or cloth to clean the polycarbonate. Avoid using abrasive materials that can scratch the surface.
- Mild detergents: Use a mild soap or detergent mixed with warm water. Harsh chemicals can damage the protective coating on the polycarbonate.
- Rinse thoroughly: After washing, rinse the polycarbonate with clean water to remove any soap residue, which can attract more dirt.
- Dry gently: Allow the sheets to air dry or use a soft towel to gently wipe them dry. Avoid leaving water spots, as they can affect the sheet’s transparency.
Inspect & Repair

Regular inspection of your polycarbonate roof can prevent minor issues from becoming major problems. Look for signs of wear and tear, such as cracks, leaks, or discolouration.
Inspection tips:
- Check for Cracks: Inspect the sheets for any cracks or splits. Small cracks can be repaired with a polycarbonate-compatible adhesive. For large damages, consider replacing the affected section.
- Seal Leaks: If you notice any leaks, check the seals and joints. Re-seal any areas where water might be sweeping through.
- Examine Fasteners: Ensure that all screws and fasteners are secure. Loose fasteners can lead to misalignment or movement or the polycarbonate sheets.
Protect from Extreme Weather
Polycarbonate panels are durable, but extreme weather conditions can still cause damage over time. Protecting your polycarbonate panels from severe weather is an essential part of maintenance.
Weather Protection Tips:
- Install Wind Braces: In areas prone to strong winds, consider installing additional braces to prevent the panels from lifting or shifting.
- Use Uv Protection: Ensure your polycarbonate panels have a UV protective layer to prevent yellowing and brittleness caused by prolonged sun exposure.
- Snow and Ice Management: In colder climates, regularly remove snow and ice buildup from the roof to prevent excess weight and potential damage.
Prevent Algae and Mould Growth
Polycarbonate roof panels, especially in humid environments, cab be susceptible to algae and mould growth. These not only affect the aesthetics but can also damage the panels over time.
Prevention tips
- Regular Cleaning: As mentioned, regular cleaning can prevent algae and mould buildup.
- Improve Ventilation: Ensure proper ventilation to reduce humidity level under the roof, which can encourage mould growth.
- Use Mould Inhibitors: Consider applying a mould inhibitor specifically designed for polycarbonate materials to prevent growth.
