What are walk-on rooflights?
Walk-on rooflights in Dorset means structural glass you can stand on, set flush into terraces and floors. Every quote follows a survey of the roof and the room below.
Western coasts take wind-driven rain, so we pay close attention to upstand height and flashing laps on exposed roofs. Many South West towns mix Georgian and Victorian terraces with modern estates, so the right product differs street by street.

Planning and building rules in England
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. 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.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. 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.

Common questions
Can it be used inside the house?
Yes. Internal walk-on panels pass light from an upper floor or ground floor to a basement below.
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.
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.
