Pitched roof windows for Seaford: the essentials
We handle pitched roof windows across East Sussex, including Seaford. In short: centre-pivot and top-hung skylights for tiled and slate roofs. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. Pitched roof windows suit lofts, attic rooms, landings and vaulted ceilings.
Seaford sits about 12 km from Rottingdean and 13 km from Eastbourne, and we cover the whole BN25 postcode district and the roads in between.

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

Common questions
Can you replace an old roof window?
Yes — replacement into the same opening is usually quicker than a new install, often a few hours per window.
Do I need planning permission for a roof window?
Often not, under householder permitted development, provided it does not project too far above the roof plane and conditions are met. Listed buildings, flats and some conservation areas are different. Our planning guide covers each nation.
Can roof windows be electric?
Yes — electric and solar-powered models open by remote and many include rain sensors.
Do I need to be at home for the survey in Seaford?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Will I need planning permission in Seaford?
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.
