Is your skylight leaking, draughty, or looking foggy? A damaged roof window can quickly compromise your home’s insulation and cause internal water damage. At TD Roofing Contractors, we provide specialized skylight repairs in Bristol, combining 20 years of roofing expertise with modern diagnostic technology.
Bristol’s coastal weather and urban pollution can take a toll on roof windows. We specialize in diagnosing and fixing:
Leaking Flashing: The most common cause of "skylight leaks." We repair or replace the metal flashing kits that bridge the gap between your roof and the window frame.
Blown Double Glazing (Foggy Glass): If your skylight looks "steamy" inside the glass, the vacuum seal has failed. We offer glass-only replacements, restoring your view and your window’s U-value without removing the entire frame.
Failed Gaskets & Seals: Over time, rubber seals become brittle. We install high-performance, weather-resistant gaskets that eliminate draughts and stop water ingress during heavy South West gales.
Mechanical & Motor Issues: Whether it’s a broken hinge, a snapped cord, or a faulty Velux Integra motor, we source genuine parts to get your window opening and closing smoothly again.

Free 4K Drone Surveys: Don’t pay for scaffolding just for an inspection. We use drones to get a 4K view of your skylight’s external seals and flashing, providing you with visual evidence of the problem.
Velux Expertise: We have decades of experience with the UK’s leading roof window brand. We know every model and year, ensuring we bring the right parts for a first-time fix.
Heritage & Modern Homes: We understand the specific mounting requirements for Victorian "Butterfly" roofs in Southville and modern loft conversions in Bradley Stoke.
Checkatrade Vetted: Our 20-year reputation is backed by hundreds of verified local reviews and a 10-year workmanship guarantee.
We provide rapid response for skylight emergencies and planned maintenance across:
Clifton & Redland (BS8, BS6): Period property skylight restoration.
Bedminster & Totterdown (BS3, BS4): Terrace loft window repairs.
Bradley Stoke & Filton (BS32, BS34): Modern roof light maintenance.
Keynsham & Longwell Green (BS30, BS31): Full glazing replacements.
Many older skylights in Bristol act as "thermal bridges," letting heat escape and causing condensation. During a repair, we can upgrade your unit with:
Low-E Toughened Glass: Reflects heat back into the room.
Argon Gas Filling: Improves insulation by up to 30% compared to older units.
Integrated Solar Blinds: Helping regulate temperature in those South-facing Bristol extensions.
In Bristol’s damp climate, condensation is common. If the water appears as tiny droplets across the whole pane, it’s likely humidity. If you see brown staining on the plasterboard or water dripping from the frame corners, you have a skylight leak. Our drone survey can confirm this in minutes.
Yes. If your frame is in good condition but the glass is cracked or "blown," we can perform a skylight glass replacement. This is significantly cheaper and faster than a full installation and involves minimal disruption to your interior décor.
Absolutely. All our permanent repairs are backed by a 10-year workmanship guarantee, and any replacement Velux glass or parts come with their own manufacturer warranties.
Minor seal repairs and mechanical fixes start from £150. Glass replacements and flashing overhauls vary by size but are always quoted as a fixed price after our initial assessment.
Most skylight repairs in Bristol are completed within 2 to 4 hours once we are on-site. We carry common Velux seals and parts in our vans to ensure a swift resolution.
