Conservation rooflights in Bath: what is involved?
For Bath 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.
Western coasts take wind-driven rain, so we pay close attention to upstand height and flashing laps on exposed roofs. Conservation rooflights suit period, listed and conservation-area roofs.
Bath is the main town we list in Somerset; we also cover nearby Trowbridge and Kingswood.
Options we can specify in Bath
- Steel or aluminium frames
- Toughened or laminated double glazing
- Flashings for slate or plain tile
- Blinds
- Manual or electric opening
- Traditional slim profile, sits low in the roof
- Often preferred by conservation officers
What to check first
- Projection above the roof line is limited — usually as flush as possible
- Lead or matching flashings may be required
Consents for conservation rooflights in Bath
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.
