How we approach conservation rooflights in Barnes
For Barnes homes and buildings we offer conservation rooflights: slim, low-profile steel-look rooflights for period and listed roofs. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
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. In Barnes, as anywhere, conservation rooflights are the usual choice for slate and plain-tile roofs where a quiet roofline matters.
Barnes sits about 2 km from Chiswick and 3 km from Putney, and we cover the whole SW13 postcode district and the roads in between.
Choices for your Barnes project
- Manual or electric opening
- Steel or aluminium frames
- Flashings for slate or plain tile
- Central vertical glazing bar
- Toughened or laminated double glazing
- Optional central glazing bar

What to check first
- Lead or matching flashings may be required
- Projection above the roof line is limited — usually as flush as possible
Do you need permission in Barnes?
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge. 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.
