A skylight is designed to bring in the light—not the rain. Because skylights sit at a lower pitch than the rest of your roof, they are often the first place a leak occurs. Whether it’s a failed seal on a modern extension or a perishing flashing on a Victorian loft conversion, a leaking skylight can cause rapid damage to your internal plasterwork and flooring.
At Jade Roofing Experts, we are London’s specialists in skylight leak detection and repair. We have extensive experience with all major brands, including Velux, Fakro, and Keylite, as well as bespoke architectural rooflights.
We repair all types of skylights and rooflights, including:
1. Flashing & Seal Failure: 90% of skylight leaks occur where the window meets the roof. Over time, the lead or aluminum flashing can pull away, or debris (leaves/moss) can block the side channels, forcing water back under the tiles.
2. Condensation Between Panes: If your skylight looks “misty” or has fog inside the glass, the hermetic seal has failed. This means the insulating gas has escaped. We can often replace the glazing unit without needing to remove the entire frame.
3. Failed “Upstands” on Flat Roofs: On flat roof extensions, skylights sit on an “upstand.” If the GRP or Felt membrane hasn’t been dressed correctly up the side of this frame, water will seep through. We specialize in resealing these critical junctions.
Identifying and sealing leaks caused by flashing failure, seal breakdown, or roof defects.
Repairing or installing new lead or aluminium flashing to ensure watertight protection.
Fixing deteriorated seals, loose frames, and perimeter gaps.
Replacing cracked or damaged glass panels and domes where repair is not possible.
We will always assess whether:
You’ll get clear, honest recommendations, not upselling.
We understand the specific flashing kits required for Velux and other major brands.
We identify the leak source before we start stripping tiles, saving you time and money.
We treat your home with respect, ensuring internal furniture is protected while we work on the roof.
If a repair is only a “temporary band-aid,” we will tell you. We focus on long-term, weatherproof solutions.
🌟 Dust and soot from the city build up in the window’s side gutters.
🔍 When it rains, the water can’t escape and “overtops” into your room.
🛠 Our Service: We provide a full “Clean & Seal” service to prevent these emergencies from happening.
We don’t just look at the glass. We inspect the surrounding tiles, the internal frame, and the external flashing. We often perform a “controlled water test” to simulate rain and identify the exact entry point.
Once we find the fault (e.g., a perished seal or a blocked side-channel), we provide a clear, written quote. There are no “hidden extras”—the price we say is the price you pay.
Using brand-specific materials (like Velux genuine flashing kits or high-performance UV-resistant sealants), we execute the repair. We then clear all drainage channels to prevent future blockages.

The chimney flue is responsible for venting hot gases and smoke. Some chimneys may have more than one flue for venting several fireplaces and stoves. This section of your chimney has to deal with immense heat and smoke. With time, creosote will build up in your flue line; if left unmaintained, this build-up can lead to chimney fires. Moreover, flue lines will break down after a while and will require replacement or repairs. A damaged flue line will allow excess condensation and heat, damaging your chimney’s structure. Furthermore, it can build up dangerous fumes in your home, which can cause several health problems. Our chimney specialists can repair/replace your flue line and provide you with highly affordable Chimney Flue Repair services.
Natural hazards such as storms and torrential rains can damage your chimney beyond repair. If you see your chimney leaning towards one side, it clearly shows that it is unreliable. It threatens your home and your family because an unstable structure like that can fall at any time. Our expert Chimney Builders will provide you with the installation of a new chimney that will be highly reliable and last a lifetime.
Some chimney issues cannot wait for days and must be resolved immediately. Many of these issues can result in fire hazards and can put your life and home at risk. Our specialists are available around the clock and will reach you in the shortest possible time.
