Sliding rooflights in Seaford: what is involved?
Sliding rooflights in Seaford means box rooflights whose glass lid slides back for walk-out roof access. We cover the BN25 district and the rest of East Sussex, with a survey before any price is fixed.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. In Seaford, as anywhere, sliding rooflights are the usual choice for staircases that rise to a roof terrace.
Neighbouring towns include Rottingdean (12 km) and Eastbourne (13 km). We offer a survey date when we reply to your enquiry.

Planning and building rules for Seaford
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. 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.
