Top Causes of Leaks in Roof Windows and How to Stop Them

Do you have to deal with roof window leaks? Have you consulted the experts to understand the cause, get the best solution, and know the leak prevention tips? If not, find out here to get peace of mind!

Adding roof windows to your home is a lovely way to let in fresh air and natural light. Roof windows are constantly exposed to the weather elements, making them susceptible to leaks. Understanding the common causes of leaks in roof windows and how to prevent them can avoid water damage and expensive repair or restoration work.

Causes of Leaks in Roof Window

Improper Installation

A faulty installation can cause leaks in a roof window. Improper fitting creates a gap that allows water penetration between the window frame and the roof structure. Installing Velux roof windows according to manufacturer guidelines ensures that all seals and flashing are in the correct position, minimising the risk of leaks.

Worn-out Seals and Gaskets

Roof windows have seals and gaskets that help prevent water from entering. Prolonged exposure to sunlight, precipitation, and varying temperatures may lead to the degradation of the seals. Brittle or cracked seals cannot keep water out when it rains heavily. Regularly inspecting seals or replacing them can help avoid leaks.

Blocked Drainage Channels

Velux roof windows have drainage channels that guide water away from the frame. When the drainage channels are clogged with debris, such as fallen leaves and dirt, the water starts gathering around your window. In extreme cases, this extra water can drip into your house and damage your ceiling or walls.

Know the Waterproofing Solutions

Regular Inspection

Always inspect your roof windows regularly, preferably before and after the rainy seasons. Examine the seal or flashing and the overall condition of the window frame. Cracks often occur long before damage that may result in a leak. Prevent leaks by identifying them early. 

Keep Drainage Channels Clear

If your roof windows have drainage channels, consider clearing all the debris. It is crucial during the fall season when leaves are likely to clog the spaces.

Do-It-Yourself Approaches and the Appropriate Time to Seek Professional Assistance 

Minor issues are ok for DIY attempts. For instance, replacing a worn-out seal or clearing out drainage channels is manageable if you understand the roof window components.

The right tools and safety gear matters when performing the do-it-yourself project.

However, if there are issues such as faulty installation or damage to flashing, call a professional. An expert can tackle the underlying problems that do-it-yourself approaches cannot resolve. Getting professional help will ensure that your roof window is watertight and secure.
