What do pitched roof windows in Orpington involve?
Thinking about pitched roof windows in Orpington? The short answer: centre-pivot and top-hung skylights for tiled and slate roofs. The longer answer depends on your roof, which is why we survey before we price.
Party walls are a fact of life in London terraces, and rooflights close to a shared wall need detailing that keeps the neighbour's side dry too. Pitched roof windows suit pitched roofs over bedrooms, stairs and bathrooms.
From Orpington to Sidcup, Swanley and Bromley, the same survey-first process applies: measure, specify, fix the price, then fit.

Planning and building rules for 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. 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.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Pitched roof windows in Orpington: questions
Can roof windows be electric?
Yes — electric and solar-powered models open by remote and many include rain sensors.
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.
Centre-pivot or top-hung?
Centre-pivot windows are easy to clean and suit most rooms. Top-hung windows open out from the top for an unobstructed view and suit lower roof pitches near eye level.

Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Can you work alongside my builder in Orpington?
