How we approach frameless structural rooflights in Welling
Our frameless structural rooflights service in Welling covers minimal glass rooflights with no visible frame from inside. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Many London roofs are reached only through the house or over neighbouring property, so lifting heavy glass is planned at survey rather than on the day. In Welling, as anywhere, frameless structural rooflights are the usual choice for rooms where you want sky without a visible frame.
Jobs in Welling are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
Choices for your Welling project
- Solar-control coatings
- Low-iron extra-clear glass
- Heated glass on some ranges
- Butt-jointed runs for long openings
- Shadow-gap or plastered reveal
- Solar-control and low-iron glass options
- Double or triple glazed structural units
Before you order: points to check
- Tolerances are tight — the opening must be built square and to size
- The internal finish (plaster, shadow gap) is agreed before order
Planning, building control and Welling
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
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. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.

Questions about frameless structural rooflights in Welling
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.
Does it cost more?
Usually, because the glass is larger and heavier and the finish needs tighter tolerances. The price table shows typical ranges.
Can a frameless rooflight be walked on?
Only if it is specified as a walk-on unit. Most frameless rooflights are for light only.
Is the survey in Welling free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Do I need to be at home for the survey in Welling?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
