What do walk-on rooflights involve?
Across Suffolk, our walk-on rooflights work covers structural glass you can stand on, set flush into terraces and floors. Survey first, fixed price second, fitting third.
Barn conversions and timber-framed homes across the East often call for conservation rooflights or bespoke glass. Flat, open landscape in much of the East means roofs take the wind, so upstand and seal details matter more than the brand of glass.

Planning and building rules in England
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.
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. 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.

Common questions
Can you see through it?
Clear glass can be seen through from both sides. A privacy interlayer or patterned frit keeps the light while obscuring the view.
Does it need a structural engineer?
Often, yes. Where the unit sits on new or altered structure, an engineer confirms the support and the manufacturer confirms the glass.
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.
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.
Will I need planning permission in Suffolk?
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.
