Do Roof Lanterns Leak?


Roof lanterns, with their elegant design and ability to flood interiors with natural light, are a sought-after feature in modern homes. 

When it comes to finding the right one for your home, a common question customers have is: do roof lanterns leak? The short answer is yes, they can, but understanding the factors contributing to these leaks and knowing how to address them is essential. 

Within this article, we’ll navigate through the intricacies of roof lantern leaks, exploring their causes, common vulnerabilities, expert fixes and the assurance of high-quality solutions, empowering you to embrace these architectural marvels worry-free. 

Factors Contributing to Roof Lantern Leaks 

Several factors can contribute to roof lantern leaks, making it fundamental to pinpoint the root cause: 

Material Quality and Construction

The quality of materials used in manufacturing a roof lantern plays a significant role in its longevity. Substandard materials or poor construction can lead to vulnerabilities that result in leaks over time. 

Here at GFD Homes, we’re proud to offer a fantastic range of roof lanterns made from high-quality aluminium, which offers much more durability and strength as opposed to other materials. 

As well as the above, aluminium roof lanterns also possess the following advantages: 

Weather Resistance

One of the primary advantages of aluminium is its innate resistance to rust and corrosion. This property makes aluminium roof lanterns ideal for enduring various weather conditions, from heavy rains to scorching sunlight, without deteriorating over time. 

Lightweight and Sturdy

Despite its strength, aluminium is remarkably lightweight. This characteristic doesn’t compromise its sturdiness, allowing for the construction of sleek and elegant roof lanterns that don’t impose excessive weight on the structure they’re installed on. 

Low Maintenance

Aluminium requires minimal maintenance compared to other materials. Its resistance to rust means it won’t deteriorate due to weather exposure, reducing the need for frequent upkeep. 

Precision in Construction

Manufacturers can precisely engineer aluminium roof lanterns to exact specifications, ensuring a snug fit and impeccable alignment during installation. This precision minimises the chances of gaps or misalignment that could potentially lead to leaks. 

Superior Quality

As mentioned above, aluminium roof lanterns are revered for their exceptional quality. The material itself boasts great strength and durability, offering robustness against harsh weather conditions and the test of time. 

When considering roof lantern materials, the advantages offered by aluminium position it as the perfect choice for homeowners seeking a long-lasting and high-quality solution. 

Installation Errors and Workmanship 

Correct installation is key to preventing leaks. Even a high-quality roof lantern can develop issues if installed incorrectly. Workmanship errors, such as improper sealing or misalignment, can pave the way for leaks. 

At GFD Homes, although our roof lanterns have been meticulously engineered for quick installation (such as our Korniche roof lantern that can be fitted within minutes!), we’d still recommend opting for professional installation for your roof lantern as this will ensure a perfect fit and reduce any potential installation errors. 

Weather Conditions and Environmental Factors 

Extreme weather conditions, prolonged exposure to harsh elements and environmental factors can weaken the structure of a roof lantern, leading to leaks over time. 

If you live in an area that experiences extreme weather conditions often, choosing a higher quality roof lantern, such as the ones we supply, will mean you are less likely to experience roof lantern leakage. This is due to these industry-leading roof lanterns being designed specifically to withstand and endure challenging elements that can lead to leaks.

Common Leak Points in Roof Lanterns 

Understanding the specific areas prone to leaks can help homeowners identify and address potential issues:

Seals and Joints

Faulty or degraded seals and joints are common culprits for roof lantern leaks. Over time, these components can wear down, allowing water infiltration. 

Glass or Panel Alignment Issues 

Misaligned glass or panels can create gaps, enabling water to seep through, particularly during heavy rainfall or adverse weather conditions. 

Guttering and Drainage Problems 

Inadequate guttering or drainage systems can cause water to accumulate around the roof lantern, leading to leaks and potential water damage. 

Identifying these common leak points is the first step towards safeguarding your roof lantern against potential issues. Regular inspections and proactive maintenance are crucial to prevent leaks from developing or worsening over time. Whether it’s ensuring proper seals and joints, addressing glass alignment, or maintaining efficient guttering, a proactive approach can significantly reduce the risk of leaks in your roof lantern.
