Pitched roof windows in Thamesmead: what is involved?
Pitched roof windows in Thamesmead means centre-pivot and top-hung skylights for tiled and slate roofs. We cover the SE28 district and the rest of Greater London, with a survey before any price is fixed.
Party walls are a fact of life in London terraces, and rooflights close to a shared wall need detailing that keeps the neighbour's side dry too. Pitched roof windows suit pitched roofs over bedrooms, stairs and bathrooms.
We work across Greater London, including Thamesmead, and in neighbouring towns such as Barking and Welling. Access, parking and how the glass reaches the roof are all checked at the survey.

Planning, building control and Thamesmead
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. 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.
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.
