Conservation rooflights in Streatham: what is involved?
Thinking about conservation rooflights in Streatham? The short answer: slim, low-profile steel-look rooflights for period and listed roofs. The longer answer depends on your roof, which is why we survey before we price.
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. Typical uses for conservation rooflights include slate and plain-tile roofs where a quiet roofline matters.
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.
Options we can specify in Streatham

Before you order: points to check

Do you need permission in 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.
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. 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.
Read the planning permission guide before you commit to a design.
