How we approach pitched roof windows in Blackheath
We handle pitched roof windows across Greater London, including Blackheath. 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.
Mansard and loft conversions are common across London, and roof windows are often set out alongside dormers on the rear slope. Pitched roof windows suit lofts, attic rooms, landings and vaulted ceilings.
We work across Greater London, including Blackheath, and in neighbouring towns such as Greenwich and Catford. Access, parking and how the glass reaches the roof are all checked at the survey.

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

Common questions
Can a roof window be fitted from inside?
In most cases, yes — only the tiles around the opening are lifted, and much of the work is done from inside the loft.
Can roof windows be electric?
Yes — electric and solar-powered models open by remote and many include rain sensors.
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 work alongside my builder in Blackheath?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
How do I book a survey in Blackheath?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
