Conservation rooflights for Diss: the essentials
Our conservation rooflights service in Diss covers slim, low-profile steel-look rooflights for period and listed roofs. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Coastal towns in the East of England see salty air, so we specify frame finishes and fixings with exposure in mind. Conservation rooflights suit period, listed and conservation-area roofs.
Diss is around 31 km from Norwich, and we survey and fit throughout that part of Norfolk, including the IP22 district.
Specification options
- Blinds
- Steel or aluminium frames
- Central vertical glazing bar
- Toughened or laminated double glazing
- Manual or electric opening
- Suits slate and plain-tile roofs
- Steel or aluminium frame in black or grey
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 Diss
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. 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.
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. 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.
