What do pitched roof windows in Streatham involve?
Thinking about pitched roof windows in Streatham? The short answer: centre-pivot and top-hung skylights for tiled and slate roofs. The longer answer depends on your roof, which is why we survey before we price.
London homes often run deep from front to back, so the middle of the ground floor is the darkest space — exactly where an overhead rooflight earns its keep. In Streatham, as anywhere, pitched roof windows are the usual choice for lofts, attic rooms, landings and vaulted ceilings.
We work across Greater London, including Streatham, and in neighbouring towns such as Balham and Clapham. Access, parking and how the glass reaches the roof are all checked at the survey.

- Flashings for tiles, slates or recessed fitting

- Integral blinds and shutters
- Manual, electric or solar-powered opening

Things we check at survey

Planning and building rules for Streatham
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.
Read the planning permission guide before you commit to a design.

Questions about pitched roof windows in Streatham
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.
Centre-pivot or top-hung?
Centre-pivot windows are easy to clean and suit most rooms. Top-hung windows open out from the top for an unobstructed view and suit lower roof pitches near eye level.

Yes. We survey and fit pitched roof windows in Streatham and across Greater London. Send your postcode and we will offer a survey date when we reply.
