Essential Guide to Fixing Roof Windows: Enhancing Durability and Performance

Roof windows, also commonly referred to as skylights, are a popular architectural element in many modern homes, offering both aesthetic appeal and practical benefits like natural lighting and improved ventilation. However, due to their exposure to the elements, roof windows can be susceptible to a variety of issues, including leaks, drafts, and damage from debris. Fixing these problems promptly is crucial to maintaining the integrity and functionality of your roof windows. This article provides a detailed guide on how to identify and fix common issues associated with roof windows, ensuring they remain an asset rather than a liability.

The first step in fixing Velux roof windows is to accurately diagnose the problem. The most common issue faced by homeowners is leaking, which can occur due to several reasons such as improper installation, failure of the window’s seals, or damage to the surrounding roofing materials. Identifying the exact source of a leak is critical and can sometimes require a thorough inspection both from inside the house and on the roof. Signs of water stains on the ceiling around the skylight or visible drips during rainy weather are clear indicators of a potential leak.

Once the source of the leak has been located, the next step is to address the sealing and flashing around the roof window. Flashing is the material used to seal the gap between the skylight frame and the roof itself, and it is often the first line of defence against water intrusion. If the flashing is damaged or improperly installed, it will need to be replaced or repaired. This typically involves removing the old flashing and applying a new layer of waterproof flashing material, which must be carefully integrated with the roof shingles to create a watertight seal.

In addition to leaks, another common issue with roof windows is condensation, which can occur if there is inadequate ventilation in the roof space or if the skylight is not properly insulated. This can lead to water accumulation, which might initially appear to be a leak. To fix this issue, it’s important to ensure that there is sufficient insulation around the window and that any ventilation ducts are clear and functional. Sometimes, installing a ventilation fan or additional vents in the roof can help mitigate condensation problems.

Drafts are another concern that can decrease the energy efficiency of roof windows. These can be caused by gaps between the window frame and the roof, or by deteriorated weather stripping. To fix drafts, apply caulking around the frame where the skylight meets the roof, and replace any old or worn weather stripping around the opening of the window. This not only prevents air leaks but also improves the overall energy performance of the window.

For cracked or broken glass in roof windows, replacement is usually the most effective solution. Handling glass can be dangerous, so it’s often best to hire a professional to do this work. They will be able to measure, order, and install the correct pane of glass for your specific model of roof window.
