How we approach sliding rooflights in Cromer
For Cromer homes and buildings we offer sliding rooflights: box rooflights whose glass lid slides back for walk-out roof access. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Coastal towns in the East of England see salty air, so we specify frame finishes and fixings with exposure in mind. In Cromer, as anywhere, sliding rooflights are the usual choice for staircases that rise to a roof terrace.
From Cromer to Fakenham, Norwich and Wymondham, the same survey-first process applies: measure, specify, fix the price, then fit.
Options we can specify in Cromer
- Anthracite, black or RAL frames
- Integrated balustrade on some ranges
- Electric drive with safety edge
- Box (glazed sides) or flat sliding lid
- Rain sensor
- Electric operation with safety stops
- Full-width, walk-out access to a roof terrace
Before you order: points to check
- Weight and point loads need a structural check
- Needs space on the roof for the lid to slide clear
Consents for sliding rooflights in Cromer
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. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
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. 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.

Questions about sliding rooflights in Cromer
How heavy is it?
Box sliders weigh hundreds of kilograms, so delivery may need a crane or lifting gear, and the structure must be checked.
What if it is raining?
Fitted with a rain sensor, an electric unit closes automatically. Most also have a manual override for power cuts.
Is it lockable?
Yes. Units lock from inside and the drive holds the lid closed.
Do I need to be at home for the survey in Cromer?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Can you work alongside my builder in Cromer?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
