Fixing Leaks in a Polycarbonate Conservatory Roof in Leicester
I have two leaks in my polycarbonate conservatory roof, but they don’t happen every time. A neighbour who’s a roofer mentioned it might depend on the wind direction. The seals around the panels may be gone.
Common Causes of Leaks in Polycarbonate Conservatory Roofs
Polycarbonate conservatory roofs are lightweight, durable, and weather-resistant, but over time, they may develop leaks due to:
- Worn or Damaged Seals: The seals around the polycarbonate panels can degrade, leading to gaps where water can enter.
- Panel Misalignment: Panels may shift slightly due to wind or temperature changes, breaking the watertight seal.
- Blocked Guttering: Debris in gutters or drainage channels can cause water to overflow and seep into the conservatory.
- Structural Damage: Cracks or warping in the panels can allow water to penetrate during strong winds or heavy rain.
Steps to Repair the Conservatory Roof
1. Inspection
- Identify Leaks: A professional will inspect the conservatory to locate the exact source of the leaks.
- Check Seals and Panels: The condition of the seals and the alignment of the panels will be evaluated.
- Guttering Check: Drainage systems will be inspected for blockages or damage.
2. Seal Replacement
- Remove Old Seals: Any degraded or worn seals will be carefully removed from the affected panels.
- Install New Seals: High-quality, weatherproof seals will be applied to restore the watertight barrier.
3. Panel Realignment
- Loose or misaligned panels will be repositioned and secured to prevent further movement.
4. Cleaning and Maintenance
- Gutters and drainage channels will be cleared of debris to ensure proper water flow.
- Panels will be cleaned to remove dirt and algae, which can contribute to seal degradation.
5. Final Testing
- The repaired roof will be tested for leaks by simulating rainfall or inspecting during wet weather.
