Walk-on rooflights for Rottingdean: the essentials
Our walk-on rooflights service in Rottingdean covers structural glass you can stand on, set flush into terraces and floors. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. Think of walk-on rooflights for roof terraces, balconies and floors above basements.
Neighbouring towns include Brighton (6 km) and Hove (8 km). We offer a survey date when we reply to your enquiry.

Planning and building rules for Rottingdean
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.
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. 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
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.
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.
Do I need to be at home for the survey in Rottingdean?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Will I need planning permission in Rottingdean?
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.
