A leaking skylight might seem like a minor issue, but if left unchecked, it can cause serious damage to your home. As we move from autumn into winter, heavy rain, wind, and colder temperatures will only make things worse.
Water leaks can lead to mould growth, rotting timber, and costly structural repairs—not to mention the heat loss that makes your home less energy-efficient. Before winter sets in is the ideal time to inspect, replace or repair your skylight; to beat the wet weather.
Whether you need a skylight repair or a complete roof skylight replacement, addressing the problem early can save you from expensive repairs down the track.
Common Causes of a Leaking Skylight
Understanding why your skylight is leaking can help you determine whether a skylight repair or replacement is needed. Some of the most common causes include:
1. Poor Skylight Installation
If a skylight isn’t properly sealed, water can seep in around the edges, leading to leaks.
2. Aging Seals and Flashing
Over time, the rubber seals and metal flashing around the skylight can deteriorate, allowing moisture to enter.
3. Condensation Issues
Sometimes mistaken for a leak, condensation can form on the inside of the skylight due to temperature differences, especially in winter.
4. Roof Damage Around the Skylight
Cracked or missing roof tiles, deteriorated shingles, or clogged gutters can all contribute to water pooling and leaking into your home.
Why You Shouldn’t Ignore a Leaking Skylight
A leaking skylight is more than just an inconvenience—it can cause serious long-term damage if ignored. Here’s why you should act fast:
Structural Damage – Water can seep into your ceiling, walls, and insulation, leading to rot and costly repairs.
Mould and Mildew Growth – A damp environment encourages mould, which can trigger allergies and respiratory issues.
Heat Loss and Higher Energy Bills – A damaged skylight can let warm air escape, making your home less energy-efficient in winter.
Rising Skylight Installation Cost – Small leaks can turn into big problems, increasing the cost of repairs or requiring a full roof skylight replacement.
How to Spot a Skylight Leak Before It Gets Worse
Catching a leaking skylight early can prevent major damage. Look out for these warning signs that your roof skylight might need replacing:
Water stains on the ceiling or walls near the skylight.
Dripping or moisture buildup during or after rain.
Condensation trapped between the skylight glass layers.
Warped or damp wooden frames surrounding the skylight.
If you notice any of these signs, don’t wait—get it checked before winter weather makes things worse.
Skylight Repair vs. Replacement: What’s the Best Option?
Not all leaks mean you need a full roof skylight replacement, but sometimes replacing an old or damaged skylight is the best long-term solution.
Temporary Fixes: A quick DIY sealant may help for minor issues, but it won’t last.
Professional Skylight Repair: If the flashing or seals are the problem, a professional skylight repair can stop leaks.
Full Skylight Installation: If your skylight is old, cracked, or poorly installed, a new skylight installation will give you better insulation, energy efficiency, and peace of mind.
How Much Does Skylight Installation Cost?
The skylight installation cost varies depending on the type, size, and complexity of the job. However, waiting too long to fix a leak could mean paying even more for extensive roof repairs.
