Conservation rooflights for Crowthorne: the essentials
We handle conservation rooflights across Berkshire, including Crowthorne. In short: slim, low-profile steel-look rooflights for period and listed roofs. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice. Conservation rooflights suit period, listed and conservation-area roofs.
Crowthorne is around 16 km from Reading, and we survey and fit throughout that part of Berkshire, including the RG45 district.

Do you need permission in Crowthorne?
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. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Can they open?
Yes, most are top-hung or side-hung for ventilation and cleaning, with manual or electric operation.
