What do walk-on rooflights in Folkestone involve?
Our walk-on rooflights service in Folkestone 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.
Larger gardens in much of the South East mean deeper rear extensions, and deeper rooms need light from above rather than only from the doors. Typical uses for walk-on rooflights include roof terraces, balconies and floors above basements.
From Folkestone to Dover, Ashford, Kent and Deal, the same survey-first process applies: measure, specify, fix the price, then fit.

- Glass on roofs people can reach must not be fragile — check the non-fragility rating
Do you need permission in Folkestone?
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. 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.
Read the planning permission guide before you commit to a design.

Common questions
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.
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.
Do you fit walk-on rooflights in Folkestone?
Yes. We survey and fit walk-on rooflights in Folkestone and across Kent. Send your postcode and we will offer a survey date when we reply.
How do I book a survey in Folkestone?
