How we approach sliding rooflights in Seaham
Our sliding rooflights service in Seaham covers box rooflights whose glass lid slides back for walk-out roof access. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
North East terraces and colliery-town housing often have rear offshoots where a rooflight brightens a narrow kitchen. Think of sliding rooflights for staircases that rise to a roof terrace.
Seaham sits about 8 km from Houghton-le-Spring and 8 km from Sunderland, and we cover the whole SR7 postcode district and the roads in between.

Planning, building control and Seaham
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. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.

Sliding rooflights in Seaham: 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.
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.
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.
Can you work alongside my builder in Seaham?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do I need to be at home for the survey in Seaham?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
