How to Clean Rooflights

Rooflights are an excellent way to let natural light into your home. They add a touch of elegance and can significantly improve indoor lighting. However, just like any other surface in your home, rooflights can get dirty over time. In this blog, we will explore why cleaning roof windows is essential, the tools you’ll need, and step-by-step instructions on how to clean rooflights effectively and safely.

Why Clean Roof Lights?

Before diving into the cleaning process, let’s first understand why rooflights need to be cleaned regularly:

Improved Natural Light

Over time, dirt and grime, debris, and algae can build up on the surface of your rooflights. This layer of grime can significantly block sunlight, reducing the amount of natural light entering your home or building.

Preservation of Materials

If left uncleaned for extended periods, dirt, bird droppings, and other contaminants can cause the material to degrade or discolour. Cleaning ensures the longevity of your rooflights, helping you avoid costly repairs or replacements.

Aesthetic Appeal

A clean rooflight enhances the overall look of your home or building. Just like with windows, dirty rooflights detract from the overall appearance, making your space feel less fresh and inviting.

Here at Lantern Superstore, we offer the choice of clear self-cleaning glass on our Brett Martin Roof Lanterns or roof lights as an optional extra. This type of glass utilises a special coating that helps to keep the glass clean by breaking down organic dirt and preventing it from sticking, perfect for those looking for a low maintenance option.

How to Clean Rooflights

Before starting the glass cleaning process, you’ll need to gather the following cleaning equipment.

Tools

Ladder

You’ll need a sturdy ladder to safely access the roof light. Ensure the ladder is tall enough to reach the rooflight comfortably without overreaching, consider using a specialist roof ladder.

Microfibre Cloth

A soft, lint-free cloth will help wipe away dirt and grime without scratching the surface.

Bucket

You’ll need a bucket to mix your cleaning solution.

Mild Solution

Use a gentle solution like warm soapy water using a mild detergent or a commercial cleaner designed for rooflights. Avoid harsh chemicals or abrasive cleaners, as they can damage the roof light.

Long-Handled Brush

A brush with soft bristles is ideal for scrubbing hard-to-reach spots on the rooflight’s surface.

Squeegee

A squeegee can be helpful for drying the rooflight’s surface and ensuring a streak-free finish.

Extension Pole (optional)

For rooflights that are difficult to reach, an extension pole with a microfibre cloth or squeegee can help you clean from the ground.

Step-by-Step Guide to Effectively Cleaning Rooflights

Follow these steps to clean your rooflight safely and effectively.

Step 1: Inspect the Roof window

Before cleaning, assess the condition of your rooflight. Look for any cracks, chips, or signs of damage. If your rooflight is in poor condition or has significant structural damage, it may be best to call in a professional for repairs before attempting to clean it. If everything looks in order, proceed with the cleaning process.

Step 2: Set Up Safety Precautions

Ensure that you have a sturdy ladder and safety gear in place. Always follow proper safety protocols when working at heights. If you’re uncomfortable or unsure about working on the roof, consider hiring a professional cleaner to handle the task.

If you are cleaning roof lights from the ground using an extension pole, double-check that your equipment is securely attached and within reach.

Step 3: Remove Loose Dirt

Before using any cleaning solution, remove any large debris such as leaves, twigs, or bird droppings from the rooflight, be careful with sharp or abrasive objects as these will scratch your roof window. You can use a broom or a soft brush to sweep away debris, taking care not to scratch the surface. This step prevents any dirt or debris from becoming smeared across the surface when cleaning.

Step 4: Prepare Your Cleaning Solution

Next, prepare your warm soapy water solution. In a bucket, mix warm water with a small amount of mild dish soap. If your rooflight is especially dirty or has stubborn stains, you can also add a small amount of vinegar solution. Avoid using harsh chemicals, as they may damage the material of the rooflight.

Step 5: Clean the Rooflight Surface

Dip a soft cloth or sponge into the soapy water and gently wipe down the rooflight’s surface. Work in sections, starting from the top and moving downward in a circular motion. Avoid pressing too hard, as this can cause scratches and possibly damage the glass. If there are any hard-to-reach areas, use a long-handled brush with soft bristles to scrub them gently.

Step 6: Rinse Off the Cleaning Solution

After wiping down the rooflight, rinse off the soapy water using a garden hose or a bucket of clean water. Be sure to thoroughly remove all excess water from the glass surface and soap residue to avoid streaks and watermarks.

Step 7: Dry the Rooflight

Once the rooflight is rinsed, use a clean, dry cloth or a non metal window squeegee to dry off any excess water. This will prevent water spots from forming and leave the rooflight streak-free.

Step 8: Check for Stubborn Stains

After the rooflight has dried, inspect it for any remaining tough stains, spots or streaks. If you notice any, use your soft cloth to buff them away.

Step 9: Regular Maintenance

To keep your rooflights in the best condition, try to clean them at least once or twice a year, or more frequently if they are in an area prone to heavy dirt buildup or bird droppings. Regular cleaning will help maintain their appearance and functionality for many years to come.

Tips for Cleaning Rooflights Safely

  • Always check the weather: Avoid cleaning rooflights during bad weather, such as high winds, rain or snow. These conditions can make cleaning dangerous.

  • Use a professional cleaning service: If you’re unsure about cleaning your rooflights yourself or are uncomfortable working at height, consider hiring a professional roof cleaning service. They have the right tools and expertise to do the job safely and efficiently.
