Skylight Repairs Brighton
Leaking or failed skylights repaired properly — stopping water at the source, not just resealing the glass.
Most Skylight Leaks Aren't the Skylight
When a skylight leaks, the instinct is to assume the window itself has failed — a cracked pane, a worn seal around the glass. In practice, a large share of skylight leaks actually come from the flashing and upstand around the frame, not the window unit.
Where a skylight meets the surrounding roof covering, whether that's tile, slate, or a flat roof membrane, there's a flashing detail sealing that junction. If the flashing has lifted, cracked, or was never dressed properly against the roof covering in the first place, water gets in around the frame — and it can look exactly like the glass itself has failed, even when it hasn't.
This matters because window specialists tend to focus on the skylight unit — the glass, the seals, the mechanism — since that's their trade. A roofer looks at the whole junction: the window, the flashing, and how it ties into the surrounding roof. On a lot of jobs, that's the difference between a repair that actually stops the leak and one that doesn't.

Repair or Replace Your Velux Skylight?
- Repair is usually the right call when the leak traces back to failed flashing, a perished seal, or a specific damaged component, and the window frame and glazing unit are otherwise sound.
- Replacement is worth considering when a skylight is genuinely old — foggy double-glazing, a stiff or failing opening mechanism, or a frame that's degraded beyond a straightforward reseal — since repeatedly patching an ageing unit often costs more over a few years than replacing it once.

Our Brighton Skylight Repair Services
Flashing and upstand repair — resealing or replacing failed flashing around the skylight frame, the single most common cause of a "leaking skylight" that isn't actually the window's fault.
Seal replacement — where the seal around the glass itself has genuinely perished, replacing it to restore a proper watertight seal.
Glass and pane repair — repairing or replacing cracked or failed panes, including double-glazed units that have lost their seal and fogged between the panes.
Roof covering repair around the skylight — where tiles, slate, or the flat roof membrane surrounding the skylight have been damaged or are contributing to the leak, addressing that as part of the same job rather than treating the skylight in isolation.
Older and non-Velux rooflights — a lot of Brighton's flat-roofed rear extensions have older GRP or dome-style rooflights rather than modern Velux units, particularly on properties extended some years ago. These are covered too, not just the newer opening roof windows most specialists focus on.

Skylight Repair FAQ's
My skylight is leaking but the glass looks fine — what's wrong?
Very likely the flashing around the frame, not the glass. This is the most common cause of a skylight leak and is often missed if the window itself is inspected without checking the surrounding roof detail.
Do you repair older skylights, or only Velux windows?
Both — older GRP and dome-style rooflights, common on Brighton's flat-roofed extensions, are repaired as often as modern Velux-style units.
Will fixing my skylight need scaffolding?
Usually not. The large majority of skylight repairs and replacements can be carried out without scaffolding, keeping both cost and disruption down.
How do I know if I need a repair or a full replacement?
If the issue is flashing, a seal, or a specific damaged part, repair is usually the more cost-effective option. If the unit itself is old, foggy, or mechanically failing, replacement is often the better long-term call — a proper inspection will tell you which applies.
Is a leaking skylight urgent?
Worth addressing promptly, particularly if water is visibly entering the property, since a small flashing failure left alone tends to get worse with each storm rather than staying static.
