How we approach frameless structural rooflights in Melksham
Our frameless structural rooflights service in Melksham 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.
Western coasts take wind-driven rain, so we pay close attention to upstand height and flashing laps on exposed roofs. Typical uses for frameless structural rooflights include architect-led extensions and long slots of light over islands or along party walls.
From Melksham to Trowbridge, Chippenham and Devizes, the same survey-first process applies: measure, specify, fix the price, then fit.
Options we can specify in Melksham
- Butt-jointed runs for long openings
- Triple glazing
- Solar-control coatings

- Shadow-gap or plastered reveal

Before you order: points to check
- Large panes need lifting gear and access planning

Do you need permission in Melksham?
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.
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. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.
See our building regulations guide for U-values, glazing limits and self-certification.

Frameless structural rooflights in Melksham: questions
Does it cost more?
Usually, because the glass is larger and heavier and the finish needs tighter tolerances. The price table shows typical ranges.
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.
Will I need planning permission in Melksham?
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.
Is the survey in Melksham free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
