What do conservation rooflights in Bodmin involve?
Thinking about conservation rooflights in Bodmin? 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.
Western coasts take wind-driven rain, so we pay close attention to upstand height and flashing laps on exposed roofs. In Bodmin, as anywhere, conservation rooflights are the usual choice for period, listed and conservation-area roofs.
Bodmin is around 33 km from Truro, and we survey and fit throughout that part of Cornwall, including the PL31 district.
What you can choose
- Steel or aluminium frames
- Flashings for slate or plain tile
- Manual or electric opening
- Toughened or laminated double glazing
- Central vertical glazing bar
- Often preferred by conservation officers
- Traditional slim profile, sits low in the roof
What to check first
- Lead or matching flashings may be required
- Conservation officers may specify size and position
Planning and building rules for Bodmin
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.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. 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.
