How we approach conservation rooflights in High Wycombe
For High Wycombe 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.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. Think of conservation rooflights for period, listed and conservation-area roofs.
Jobs in High Wycombe are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
What you can choose
- Manual or electric opening
- Steel or aluminium frames
- Toughened or laminated double glazing
- Central vertical glazing bar
- Flashings for slate or plain tile
- Steel or aluminium frame in black or grey
- Traditional slim profile, sits low in the roof
What to check first
- Projection above the roof line is limited — usually as flush as possible
- Lead or matching flashings may be required
Do you need permission in High Wycombe?
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. 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.
