Skylight replacement in Wood Green: what is involved?
Thinking about skylight replacement in Wood Green? The short answer: replacing tired domes and failed glass with a modern rooflight. The longer answer depends on your roof, which is why we survey before we price.
Mansard and loft conversions are common across London, and roof windows are often set out alongside dormers on the rear slope. In Wood Green, as anywhere, skylight replacement is the usual choice for yellowed domes, misted glass and leaking roof windows.
We work across Greater London, including Wood Green, and in neighbouring towns such as Muswell Hill and Crouch End. Access, parking and how the glass reaches the roof are all checked at the survey.
Specification options

Before you order: points to check
- A replacement is a chance to meet current thermal standards
- Enlarging the opening changes the structure and may need approval
Planning, building control and Wood Green
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. 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.
