Conservation rooflights in Runcorn: what is involved?
Our conservation rooflights service in Runcorn 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.
Exposed hillside towns in the North West need flashing and seal details that cope with wind-driven rain. In Runcorn, as anywhere, conservation rooflights are the usual choice for period, listed and conservation-area roofs.
We work across Cheshire, including Runcorn, and in neighbouring towns such as Widnes and Halewood. Access, parking and how the glass reaches the roof are all checked at the survey.
Specification options
- Flashings for slate or plain tile
- Manual or electric opening
- Central vertical glazing bar
- Toughened or laminated double glazing
- Steel or aluminium frames
- Suits slate and plain-tile roofs
- Double glazed behind a period look
Before you order: points to check
- Listed building consent is needed for listed buildings
- Lead or matching flashings may be required
Do you need permission in Runcorn?
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.
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.
