Common Issues with Korniche Roof Lanterns

Even though Korniche roof lanterns are designed for exceptional performance that can last years, certain issues can arise due to installation errors, wear and tear, or external factors. 

Let’s explore the most frequent challenges and how to identify them.

Why Do Korniche Roof Lanterns Leak?

Leaks are among the most common concerns and issues homeowners face when it comes to roof lanterns. 

Potential roof lantern leaks can be caused by improper installation, degraded seals, or external damage from falling debris. 

Weather conditions such as heavy rain, snow, or high winds can exacerbate the problem.

By choosing to opt for professional roof lantern installation, you can significantly reduce the chances of problems after your purchase. Regular maintenance will also help you to notice any potential issues early, giving you more than enough time to contact a professional and get the issue resolved. 

Signs of Installation Problems with Roof Lanterns

The Installation of your Korniche roof lantern is key to ensuring it maintains its performance over time. 

When the installation process isn’t carried out meticulously, problems such as misaligned parts or insufficient or improper sealing can arise.

Additional indicators of installation errors can include:

  • Noisy Operation: Rattling or creaking noises, especially during windy conditions, may indicate loose fittings.
  • Fogging Between Glass Panes: This could signal improper sealing during the glazing process.
  • Visible Gaps: If daylight is visible through gaps in the frame or joints, it’s a red flag for poor installation.

What Causes Drafts in Korniche Roof Lanterns?

Drafts aren’t just annoying—the unwanted cold air they bring can also increase your energy bills! 

In most cases, drafts result from worn-out seals or a poor fitting of the roof lantern during the initial installation. 

The fluctuation in temperature between seasons can also cause materials to expand and contract, creating or exacerbating gaps over time.

Drafts are usually caused by the following:

  • Improperly fitted gaskets.
  • Wear and tear due to lack of maintenance.

Professional installation and regular roof lantern maintenance will help to reduce the chances of experiencing roof lantern drafts. 

How to Identify Operational Issues with Roof Lanterns

While operational problems, such as stiffness with the opening and closing mechanism for the vents, are less common but can still occur. 

This can often be caused by debris build-up, rusting components, or incorrect fitting.

Signs of Operational Problems:

  • Stiff Hinges: Vents that feel difficult to move might need cleaning or lubrication.
  • Uneven Movement: Misaligned parts can cause vents or panes to open at an angle.

If you experience any of the above issues, contacting your fitter or supplier is the best course of action to get the problem fixed correctly.

Fixing Leaks and Installation Errors

Troubleshooting roof lantern issues doesn’t have to be daunting. With the right tools and know-how, a trusted professional can address many problems effectively.

How to Troubleshoot Roof Lantern Leaks

If you’ve identified leaks, taking swift action and contacting your fitter is key to preventing long-term damage.

Here’s what you should look out for if you think your roof lantern may be suffering from a leak:

  1. Inspect Thoroughly: Check the perimeter of the roof lantern and any visible joints for gaps, cracks, or loose seals.
  2. Remove Debris: Leaves, moss, and other debris can weaken seals. Use a soft brush or cloth to clean the area.
  3. Repair Seals: Your fitter can apply a high-quality, weatherproof silicone sealant to damaged or cracked seals. For best results, ensure the surface is dry and clear of debris before application.
  4. Replace Worn Components: If the rubber gaskets or weatherproofing tape appear damaged, contact the supplier or fitter so that they can be replaced with compatible materials.

Steps to Fix Korniche Roof Lantern Installation Errors

When it comes to installation problems with your Korniche roof lantern, it is always best to contact the supplier or your fitter as these fixes will require a careful approach to avoid causing further damage.

What can be done to fix installation errors:

  1. Reinstall Misaligned Parts: Remove and refit misaligned glazing bars or panels using Korniche’s installation guide for reference.
  2. Add Insulation: If the draft persists, consider adding thermal tape or foam insulation around the edges of the frame.
  3. Check Fasteners: Loose screws or fasteners can lead to instability. Tighten all components to their manufacturer-recommended settings. 

Best Practices for Sealing Roof Lanterns

Sealing your Korniche roof lantern correctly ensures longevity and peak performance.

Dos and Don’ts:

  • Do use professional-grade sealants that are UV and weather-resistant.
  • Don’t over-apply sealant, as this can interfere with the frame’s operation.
  • Do inspect seals annually to catch wear before it becomes an issue.
  • Do contact a professional to rectify any issues you may have with the seal
