Rooflights

Bring natural daylight flooding into your home with quality rooflights in London from Lord Glazing. Rooflights and skylights transform dark loft conversions, kitchen extensions, hallways and landings into bright, welcoming spaces — often delivering far more light than a vertical window of the same size. At Lord Glazing we supply and install rooflights for both flat and pitched roofs, using energy-efficient glazing that keeps heat in and glare out. With 15+ years' experience, 5,000+ completed projects and a 4.9★ rating from over 200 reviews, we make adding light to your home simple, clean and reliable.

Why choose rooflights in London

London homes are often built close together, which can leave interior rooms and extensions short on natural light. Rooflights solve this by drawing daylight in from above, brightening spaces that side windows cannot reach and reducing the need for artificial lighting. They are especially valuable in loft conversions, single-storey kitchen extensions and flat-roof projects. Modern rooflights also offer excellent thermal performance and ventilation. As a FENSA registered, GGF member installer that is TrustMark approved, Checkatrade verified and fully insured, we ensure every rooflight is fitted to be weather-tight, efficient and built to last.

Key benefits

• Maximum daylight — overhead glazing delivers more light than vertical windows.
• Brighter rooms — ideal for lofts, extensions, hallways and internal spaces.
• Energy efficiency — low-E sealed glazing reduces heat loss.
• Ventilation — opening rooflights help reduce heat and humidity.
• Added value — light-filled rooms are highly desirable to buyers.
• Weather-tight installation — properly flashed and sealed for total peace of mind.

Options & materials

We supply a range of rooflights to suit your roof type and project:

• Flat-roof rooflights — fixed or opening units for extensions and flat-roof homes.
• Pitched-roof windows — centre-pivot and top-hung skylights for loft conversions.
• Walk-on and walkable glass — for terraces and roof gardens.
• Lantern rooflights — multi-pane structures that make a stunning feature over kitchens and dining areas.
• Glass options — solar-control, self-cleaning, obscured and toughened safety glass.

Rooflights work beautifully alongside a new conservatory or garden-facing doors to create a light, open living space.

A local team can reach your home across the capital.

Where rooflights work best in London homes

Because London properties are often terraced or closely spaced, daylight can be hard to bring into the centre of a home — and that is exactly where rooflights excel. In a single-storey kitchen or dining extension, a large rooflight or a glazed roof lantern can transform the space, pouring daylight onto worktops and dining tables where side windows simply cannot reach. In loft conversions, pitched-roof windows turn dark attics into bright, airy bedrooms or studies. Rooflights also work wonderfully over stairwells, landings and internal hallways that would otherwise rely entirely on artificial light. For roof terraces and accessible flat roofs, walk-on glass lets light flow into the rooms below while creating a usable surface above. We assess orientation, structure and the path of the sun during your free no-obligation survey to position each rooflight for the best possible result.

Frequently Asked Questions

Do rooflights leak?

Not when correctly installed. Our fully insured fitters use proper flashing kits and weather-tight seals appropriate to your roof type, so your rooflight stays watertight for years, backed by our 10-year guarantee.

Can I have a rooflight on a flat roof?

Yes. We supply fixed and opening flat-roof rooflights, as well as lantern and walk-on units, all designed specifically for flat-roof applications.

Will a rooflight make my room too hot?

Modern rooflights use solar-control glass to limit heat gain and glare, and opening units provide ventilation, so your room stays bright without overheating.

Do I need planning permission for a rooflight?

Many rooflights are permitted development if they sit within set limits, but conservation areas and listed buildings have stricter rules. We advise on this during your survey.

How long does installation take?

A typical rooflight is installed within a day or two depending on the structural work required. We keep the process clean and explain the timeline before we start.
