Conservation rooflights for Farnborough: the essentials
Our conservation rooflights service in Farnborough 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.
Larger gardens in much of the South East mean deeper rear extensions, and deeper rooms need light from above rather than only from the doors. Typical uses for conservation rooflights include slate and plain-tile roofs where a quiet roofline matters.
From Farnborough to Camberley, Aldershot and Fleet, the same survey-first process applies: measure, specify, fix the price, then fit.
What you can choose
- Blinds
- Toughened or laminated double glazing
- Flashings for slate or plain tile
- Steel or aluminium frames
- Central vertical glazing bar
- Traditional slim profile, sits low in the roof
- Optional central glazing bar
What to check first
- Projection above the roof line is limited — usually as flush as possible
- Listed building consent is needed for listed buildings
Consents for conservation rooflights in Farnborough
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.
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.
