Sliding rooflights in Thornton-Cleveleys: what is involved?
Thinking about sliding rooflights in Thornton-Cleveleys? 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.
The North West gets more rain than most of England, so upstand height, membrane detailing and rain sensors on opening units are not optional extras. Sliding rooflights suit staircases that rise to a roof terrace.
We work across Lancashire, including Thornton-Cleveleys, and in neighbouring towns such as Fleetwood and Blackpool. Access, parking and how the glass reaches the roof are all checked at the survey.
What you can choose
- Integrated balustrade on some ranges
- Electric drive with safety edge
- Double or triple glazing
- Anthracite, black or RAL frames
- Rain sensor
- Lockable from inside
- Full-width, walk-out access to a roof terrace
Things we check at survey
- Electric units need a dedicated supply and commissioning
- The stair opening and headroom must meet Building Regulations
Consents for sliding rooflights in Thornton-Cleveleys
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.
See our building regulations guide for U-values, glazing limits and self-certification.
