How we approach frameless structural rooflights in Leigh
Thinking about frameless structural rooflights in Leigh? The short answer: minimal glass rooflights with no visible frame from inside. The longer answer depends on your roof, which is why we survey before we price.
Exposed hillside towns in the North West need flashing and seal details that cope with wind-driven rain. Think of frameless structural rooflights for rooms where you want sky without a visible frame.
From Leigh to Atherton, Tyldesley and Golborne, the same survey-first process applies: measure, specify, fix the price, then fit.
What you can choose
- Solar-control coatings
- Heated glass on some ranges
- Triple glazing
- Shadow-gap or plastered reveal
- Low-iron extra-clear glass
- Double or triple glazed structural units
- Can run along party walls and side returns
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 Leigh
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. 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.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about frameless structural rooflights in Leigh
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.
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.
Does it cost more?
Usually, because the glass is larger and heavier and the finish needs tighter tolerances. The price table shows typical ranges.
How do I book a survey in Leigh?
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 Leigh?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
