What do pitched roof windows in Catford involve?
Pitched roof windows in Catford means centre-pivot and top-hung skylights for tiled and slate roofs. We cover the SE6 district and the rest of Greater London, with a survey before any price is fixed.
Mansard and loft conversions are common across London, and roof windows are often set out alongside dormers on the rear slope. Pitched roof windows suit pitched roofs over bedrooms, stairs and bathrooms.
Catford sits about 2 km from Lewisham and 3 km from Blackheath, and we cover the whole SE6 postcode district and the roads in between.

Planning and building rules for Catford
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.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
Can you replace an old roof window?
Yes — replacement into the same opening is usually quicker than a new install, often a few hours per window.
Can roof windows be electric?
Yes — electric and solar-powered models open by remote and many include rain sensors.
Will it need building regulations approval?
Fitting a new roof window usually involves cutting rafters and changing the thermal envelope, so building control approval (or, in England and Wales, a competent-person route) is normally needed. We tell you which applies.
Do I need to be at home for the survey in Catford?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Will I need planning permission in Catford?
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.
