How we approach sliding rooflights in Sudbury
Thinking about sliding rooflights in Sudbury? The short answer: box rooflights whose glass lid slides back for walk-out roof access. The longer answer depends on your roof, which is why we survey before we price.
Barn conversions and timber-framed homes across the East often call for conservation rooflights or bespoke glass. In Sudbury, as anywhere, sliding rooflights are the usual choice for walk-out access where a hatch would feel cramped.
Sudbury sits about 20 km from Colchester and 21 km from Haverhill, and we cover the whole CO10 postcode district and the roads in between.

- Anthracite, black or RAL frames

Things we check at survey

Planning, building control and Sudbury
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.
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.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
Is it lockable?
Yes. Units lock from inside and the drive holds the lid closed.
Can children open it?
Controls can be key-switched or placed out of reach. We will set the controls up to suit the household.
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 Sudbury?
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 Sudbury?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
