Sliding rooflights in Gerrards Cross: what is involved?
Thinking about sliding rooflights in Gerrards Cross? The short answer: box rooflights whose glass lid slides back for walk-out roof access. The longer answer depends on your roof, which is why we survey before we price.
Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice. In Gerrards Cross, as anywhere, sliding rooflights are the usual choice for walk-out access where a hatch would feel cramped.
We work across Buckinghamshire, including Gerrards Cross, and in neighbouring towns such as Chalfont St Peter and Uxbridge. Access, parking and how the glass reaches the roof are all checked at the survey.

- Electric drive with safety edge

Things we check at survey

Planning, building control and Gerrards Cross
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.
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.
Read the planning permission guide before you commit to a design.
