Steps for Cleaning Skylights

By following this step-by-step guide to cleaning skylights, you can clean them with complete safety. 

#1 Removing Debris And Cobwebs 

Removing debris and cobwebs is an important first step when cleaning skylights. To initiate the cleaning process, you can begin by using a soft-bristled brush to sweep away cobwebs and debris from the surface of the skylight. Additionally, you can use a vacuum cleaner with a brush attachment to suction up the larger debris, like leaves or branches. 

If the skylight is hard to reach from the floor, you can use a long-handled brush to reach its surface. It’s important to exercise caution when working on a ladder and to ensure that it is stable and placed on a flat surface. After removing debris and cobwebs, you can clean the glass or plastic surface of the skylight. 

#2 Cleaning A Glass Or Plastic Surface 

When cleaning skylights, cleaning the glass or plastic surface is essential. To begin, you can mix a small amount of mild detergent with warm water in a bucket. Using a soft cloth or sponge, apply the solution to the surface of the skylight, making sure to clean the surface thoroughly. 

Pay special attention to any spots or stains. Finally, dry the surface with a soft cloth or squeegee to ensure no water spots or streaks are left on the surface. By using a microfiber cloth, you can prevent any scratches from occurring. 

Once you have cleaned the surface, it is important to rinse it with clean water to remove any remaining detergent. 

#3 Cleaning The Frames And Seals 

Cleaning the frames and seals of skylights is essential to maintain their integrity and function. To begin, you can use a non-abrasive cleaner and a soft cloth. This will prevent any damage to the frames and seals. 

Apply the cleaner to the frames and seals and wipe them down thoroughly with a soft cloth to remove dirt, grime, and other buildups. In addition to cleaning and wiping the frames and seals, you must inspect them for any cracks or damage. If you find any cracks or damage, addressing them as soon as possible is essential to avoiding drafts and leaks. 


Tips For Different Types Of Skylights 

Different types of skylights may require different cleaning methods. Therefore, you must consult the skylight manufacturer’s instructions for specific recommendations for cleaning. 

For instance, some skylights may be made of a material that is sensitive to certain chemicals, so it’s important to make sure you’re using a cleaner that is safe for the material. Additionally, some skylights may require special cleaning methods, such as a special solution to remove stains or specialized tools to reach hard-to-reach areas. 

Safety Precautions

You can reduce the risks of hurting yourself by having proper knowledge about safety precautions. The following guide explains all the safety measures you should take to clean your skylights. 

#1 Safety Measures When Cleaning Skylights

Safety is of the utmost importance when cleaning skylights. You should start by using a stable ladder that is placed on a flat surface. Before climbing the ladder, ensure that all locks are securely in place and that the ladder is in good condition. It’s also a good idea to have someone help you by holding the ladder while climbing up and down.

#2 Tips For Preventing Injuries

If you are cleaning the skylights at a high height, you must have a safety rope with you to avoid injuries. 

Always make sure to follow the manufacturer’s instructions for cleaning and maintenance, as some skylights may require special cleaning methods or tools. When cleaning skylights, it’s important to avoid using harsh chemicals or abrasive materials that can damage the skylight or cause injury.

Maintaining Skylights

Regular maintenance is important for various reasons. Some of these include the following: 

#1 Regular Inspection  

In a residential or commercial building, by regularly inspecting your roof, you can prevent many mishaps, like glass cracking, dust accumulation, and sunlight blockage. If you find any cracks and spots while inspecting skylights, addressing them immediately can increase their lifespan. 

Additionally, make sure that skylights are properly sealed, as leaving them unintentionally open can imbalance the interior temperature and allow the external elements to enter. 

#2 Operate Them Properly

If the skylight is meant to open, make sure the mechanism is working properly and that it is properly sealed when closed. 

#3 Professional Maintenance 

Hire a professional skylight company for annual maintenance to ensure that the skylight is in good condition and catch any issues early on.
