How To Clean Roof Lanterns


Roof lanterns are a stylish addition to any space, providing abundant natural light and a touch of architectural elegance. 

When it comes to ensuring their longevity and pristine appearance, proper cleaning is essential. 

Whether you’re dealing with environmental debris, bird droppings, rainwater streaks, moss growth or insect residues, this guide will walk you through the process of keeping your roof lanterns in top condition. We’ll also explore the fascinating world of self-cleaning glass and answer some frequently asked questions to help you make the most of your investment. 

How do roof lanterns get dirty? 

Here are the most common ways a roof lantern can get dirty: 

Environmental debris

Roof lanterns are exposed to a range of elements, making them susceptible to environmental debris such as dust, leaves and pollen. Over time, these particles can accumulate on the surface, affecting both the appearance and the amount of natural light entering your space. 

Bird droppings 

Bird dropping can be a common issue, especially in outdoor spaces. The acidic nature of bird droppings can cause stains and damage to the glass if not addressed properly and promptly. 

Rainwater streaks 

Rainwater carries impurities that can leave streaks on the glass as it dries. This is a natural occurrence and may require regular cleaning to maintain the pristine look of your roof lantern. 

Moss growth 

In shaded or damp areas, moss can grow on the roof lantern, contributing to a less appealing aesthetic. Regular maintenance is essential to prevent moss from taking hold. 

Insect residues 

Insects may leave residues on the glass, particularly during certain seasons. These residues can accumulate and affect the clarity of the glass. 

How does self-cleaning glass work? 

Self-cleaning glass is designed with a special coating that reacts with sunlight to break down organic dirt and debris. The process, known as photocatalysis, helps to keep the glass cleaner for much longer periods by reducing the adhesion of dirt. 

Do you still need to clean roof lanterns with self-cleaning glass? 

With the innovative technology of self-cleaning glass, the need for frequent exterior cleaning becomes virtually obsolete. While you may feel the need to clean the interior of your roof lantern now and again, the self-cleaning feature ensures that the outside remains remarkably clear for extended periods, potentially sparing you from this task for many years to come. 

How to clean a roof lantern 

If you would like to clean your roof lantern, we would recommend using the following methods: 

Interior glass 

For interior glass, a mild glass cleaner and a soft cloth or sponge can be used. Wipe down the glass in a circular motion to remove any smudges or fingerprints. 

Exterior glass 

To clean roof lanterns without self-cleaning glass you just need a hose or a bucket of soapy water, along with a non-abrasive sponge. Gently scrub the glass and rinse thoroughly with water. Always avoid using harsh chemicals or abrasive materials that may damage the roof lantern.
