Walk-on rooflights in Crowthorne: what is involved?
Walk-on rooflights in Crowthorne means structural glass you can stand on, set flush into terraces and floors. We cover the RG45 district and the rest of Berkshire, with a survey before any price is fixed.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. In Crowthorne, as anywhere, walk-on rooflights are the usual choice for roof terraces, balconies and floors above basements.
Crowthorne is around 16 km from Reading, and we survey and fit throughout that part of Berkshire, including the RG45 district.

Consents for walk-on rooflights in Crowthorne
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. 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.

Common questions
Will it sit flush with my paving?
Yes — the unit is set on its own upstand so the glass finishes level with the surrounding paving or decking.
Is the glass slippery?
Walk-on glass has an anti-slip finish, usually a ceramic frit or etched pattern. Like any outdoor surface it needs cleaning to stay effective.
How much weight can a walk-on rooflight take?
It depends on the model and size. Manufacturers state a design imposed load for each unit; we only specify a unit whose rating suits the use, such as a private terrace or a busier area.
Is the survey in Crowthorne free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Can you work alongside my builder in Crowthorne?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
