Sliding rooflights in Cambridge: what is involved?
Sliding rooflights in Cambridge means box rooflights whose glass lid slides back for walk-out roof access. We cover the CB1 district and the rest of Cambridgeshire, with a survey before any price is fixed.
Flat, open landscape in much of the East means roofs take the wind, so upstand and seal details matter more than the brand of glass. In Cambridge, as anywhere, sliding rooflights are the usual choice for walk-out access where a hatch would feel cramped.
Cambridge sits about 20 km from St Ives and 20 km from Newmarket, and we cover the whole CB1 postcode district and the roads in between.

Consents for sliding rooflights in Cambridge
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. 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.
Read the planning permission guide before you commit to a design.

Sliding rooflights in Cambridge: questions
Is a sliding rooflight better than an access hatch?
For daily use, usually yes — you walk out under open sky instead of climbing through a hinged hatch. A hatch costs less and suits occasional access.
Does it need planning permission?
A box unit that projects above the roof plane can need planning permission, especially on the front of a house or in a conservation area. We check before you order.
What if it is raining?
Fitted with a rain sensor, an electric unit closes automatically. Most also have a manual override for power cuts.
Do I need to be at home for the survey in Cambridge?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
