Sliding rooflights in Plymouth: what is involved?
Sliding rooflights in Plymouth means box rooflights whose glass lid slides back for walk-out roof access. We cover the PL1 district and the rest of Devon, with a survey before any price is fixed.
Holiday lets and second homes across the South West often want roof windows with blinds and remote opening for when the house is empty. In Plymouth, as anywhere, sliding rooflights are the usual choice for staircases that rise to a roof terrace.
Plymouth is the main town we list in Devon; we also cover nearby Plymstock and Paignton.

Do you need permission in Plymouth?
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. 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.

Box sliders weigh hundreds of kilograms, so delivery may need a crane or lifting gear, and the structure must be checked.

Fitted with a rain sensor, an electric unit closes automatically. Most also have a manual override for power cuts.
