Frameless structural rooflights in Keighley: what is involved?
Thinking about frameless structural rooflights in Keighley? 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.
Many Yorkshire homes have had kitchen extensions with flat roofs, where a larger glass rooflight is a straightforward upgrade from an old dome. Frameless structural rooflights suit rooms where you want sky without a visible frame.
Keighley is around 25 km from Leeds, and we survey and fit throughout that part of West Yorkshire, including the BD21 district.

Planning and building rules for Keighley
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.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. 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 Keighley: questions
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.
Can it open?
Some frameless designs include a sliding or hinged opening element, but most are fixed. Pair with an opening unit if you need ventilation.
Does it cost more?
Usually, because the glass is larger and heavier and the finish needs tighter tolerances. The price table shows typical ranges.
Will I need planning permission in Keighley?
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.
Do I need to be at home for the survey in Keighley?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
