How we approach pitched roof windows in Greenwich
Thinking about pitched roof windows in Greenwich? 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.
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.
Greenwich sits about 2 km from Blackheath and 3 km from Lewisham, and we cover the whole SE10 postcode district and the roads in between.

Consents for pitched roof windows in Greenwich
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. 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. 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.

Questions about pitched roof windows in Greenwich
Can a roof window be fitted from inside?
In most cases, yes — only the tiles around the opening are lifted, and much of the work is done from inside the loft.
Can roof windows be electric?

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.
