How we approach pitched roof windows in Redhill
Our pitched roof windows service in Redhill covers centre-pivot and top-hung skylights for tiled and slate roofs. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. In Redhill, as anywhere, pitched roof windows are the usual choice for pitched roofs over bedrooms, stairs and bathrooms.
Jobs in Redhill are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
Specification options
- Centre-pivot or top-hung
- Double or triple glazing
- Flashings for tiles, slates or recessed fitting
- Manual, electric or solar-powered opening
- Combination and stacked windows
- Usually fitted in a day

What to check first
- Escape-window rules can apply to loft rooms
- Insulation collars and vapour control must be detailed
Planning, building control and Redhill
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.
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. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.

Pitched roof windows in Redhill: questions
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.
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.
Can roof windows be electric?
Yes — electric and solar-powered models open by remote and many include rain sensors.
Can you work alongside my builder in Redhill?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Is the survey in Redhill free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
