How we approach hinged roof access rooflights in Orpington
Our hinged roof access rooflights service in Orpington covers hinged glazed hatches over a stair or ladder for roof terrace access. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Victorian and Edwardian terraces with narrow side returns are typical of much of London, and a glass roof or long flat rooflight is the usual way to keep the back rooms bright once the return is built over. Hinged roof access rooflights suit reaching a roof terrace, plant area or flat roof from a stair or ladder.
Orpington is around 21 km from central London, and we survey and fit throughout that part of Greater London, including the BR6 district.

Do you need permission in Orpington?
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. 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.

Hinged roof access rooflights in Orpington: questions
Can it replace an old loft hatch?
Where there is a flat roof above, yes. On a pitched roof, an access roof window is the equivalent.
How big does an access hatch need to be?
Big enough to climb through comfortably for the stair or ladder you have. For a stair, we size it to the stair width and the headroom; for occasional plant access a smaller hatch can work.
Can it be opened from the roof?
Many units have an external handle or key for opening from outside. If you need that, tell us at survey.
Will I need planning permission in Orpington?
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.
