Conservation rooflights for Dover: the essentials
Thinking about conservation rooflights in Dover? 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.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. Typical uses for conservation rooflights include period, listed and conservation-area roofs.
From Dover to Folkestone, Deal and Canterbury, the same survey-first process applies: measure, specify, fix the price, then fit.
Specification options
- Flashings for slate or plain tile
- Toughened or laminated double glazing
- Steel or aluminium frames
- Blinds
- Central vertical glazing bar
- Traditional slim profile, sits low in the roof
- Double glazed behind a period look
What to check first
- Projection above the roof line is limited — usually as flush as possible
- Lead or matching flashings may be required
Planning, building control and Dover
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.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.
