Frameless structural rooflights in Dartford: what is involved?
We handle frameless structural rooflights across Kent, including Dartford. In short: minimal glass rooflights with no visible frame from inside. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. Typical uses for frameless structural rooflights include architect-led extensions and long slots of light over islands or along party walls.
Dartford is around 29 km from Maidstone, and we survey and fit throughout that part of Kent, including the DA1 district.
What you can choose
- Solar-control coatings
- Shadow-gap or plastered reveal
- Heated glass on some ranges
- Butt-jointed runs for long openings
- Low-iron extra-clear glass
- Solar-control and low-iron glass options
- Nothing but glass visible from inside
What to check first
- The internal finish (plaster, shadow gap) is agreed before order
- Large panes need lifting gear and access planning
Planning, building control and Dartford
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.

Questions about frameless structural rooflights in Dartford
Will I see the edge of the glass?
From inside, the reveal is finished up to the glass so the edge is hidden. From outside you will see the glass and its edge seal.
How is it lifted onto the roof?
Larger panes go up with a vacuum lifter, a hoist or a crane. We plan access at survey.
Is frameless glass as strong as a framed rooflight?
Yes — it is structural glass designed for the job. The support is hidden rather than missing.
How do I book a survey in Dartford?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Do I need to be at home for the survey in Dartford?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
