Flat rooflights for Keighley: the essentials
For Keighley homes and buildings we offer flat rooflights: fixed double or triple glazed rooflights for flat roofs and extensions. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Stone-built terraces are common across Yorkshire, and roof windows in the rear slope are a popular way to light attic rooms. Think of flat rooflights for landings, bathrooms and rear extensions with flat roofs.
Keighley sits about 10 km from Shipley and 13 km from Guiseley, and we cover the whole BD21 postcode district and the roads in between.
What you can choose
- Frame colours: anthracite, black, white or RAL
- Square, rectangular or long-format sizes
- Double or triple glazing
- Solar-control or self-cleaning outer pane
- Insulated kerb or timber upstand built to suit
- Pairs with an opening unit where you also need ventilation
- Inner pane laminated for safety overhead
What to check first
- Rooflights count toward glazing in an extension, which matters for Building Regulations energy and overheating rules
- New openings in an existing roof need a structural check on joists
Consents for flat rooflights in 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.
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. 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.

Common questions
Can you fit into my existing flat roof?
Yes. We form a new opening, trim the joists, build and waterproof an upstand and make good the ceiling. A survey confirms the joist direction and roof build-up first.
Can a flat rooflight be walked on?
Not unless it is designed as a walk-on unit with structural laminated glass. A standard flat rooflight is for light only — if the roof is used as a terrace, choose a walk-on rooflight instead.
Will it make the room too hot?
A big unglazed-to-sky area can add solar gain in summer. Solar-control glass, a blind, or pairing a fixed unit with an opening one keeps it comfortable.
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.
Do you fit flat rooflights in Keighley?
