How we approach conservation rooflights in Chester-le-Street
Conservation rooflights in Chester-le-Street means slim, low-profile steel-look rooflights for period and listed roofs. We cover the DH3 district and the rest of Durham, with a survey before any price is fixed.
Older flat-roofed extensions in the North East are often due a new roof covering — the right time to upgrade the rooflight too. Typical uses for conservation rooflights include slate and plain-tile roofs where a quiet roofline matters.
We work across Durham, including Chester-le-Street, and in neighbouring towns such as Washington and Houghton-le-Spring. Access, parking and how the glass reaches the roof are all checked at the survey.

Planning and building rules for Chester-le-Street
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. 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.
