What is a Roof Lantern?

Before diving into the topic of leaks, let’s clarify what a roof lantern is. Essentially, it’s a glazed structure that sits on top of a flat roof, allowing light to penetrate into your home. Roof lanterns vary in design, but they typically feature multiple panes of glass framed by strategically placed supports. Their popularity has surged due to their ability to create an airy, spacious ambiance, making rooms feel larger and more inviting.

Why Do Roof Lanterns Leak?

The beauty of roof lanterns can sometimes overshadow concerns about their durability. So, does a roof lantern leak? The short answer is: it can, especially if not properly installed or maintained.

Common Causes of Leaks

  1. Poor Installation: If the lantern is not installed correctly, gaps can form, allowing water to seep through. This is particularly common around the edges where the lantern meets the roof.

  2. Sealant Deterioration: Over time, the sealants used in roof lantern installations can degrade due to exposure to the elements. This can result in gaps that allow rainwater to enter.

  3. Condensation: Sometimes, leaks are not from outside water but rather from condensation forming inside. This can be exacerbated in spaces with high humidity, especially in kitchens or bathrooms.

  4. Blocked Drains: If the drainage system is obstructed, water can pool on the roof, eventually finding its way into susceptible areas of the lantern.

Preventive Measures to Avoid Leakage

Now that you know the potential causes, let’s explore actionable steps you can take to minimize the risk of leaks:

  1. Professional Installation: Always opt for experienced professionals who understand the nuances of roof lantern installations. A well-installed lantern is less likely to leak.

  2. Regular Maintenance: Schedule regular inspections to check for worn sealants, blocked drains, or any signs of cracking. Address any issues promptly.

  3. Quality Materials: Invest in high-quality materials for your lantern and installation components. This may prove to be more cost-effective in the long run.

  4. Proper Ventilation: Ensure adequate ventilation in the area where the roof lantern is installed. This can help manage indoor humidity levels and reduce condensation.

  • Identify the Source: Carefully inspect the lantern and surrounding area to pinpoint where the leak is coming from.
