Skylight replacement for Denton: the essentials
Skylight replacement in Denton means replacing tired domes and failed glass with a modern rooflight. We cover the M34 district and the rest of Greater Manchester, with a survey before any price is fixed.
Stone and brick terraces are typical across the North West, and roof windows in rear slopes are a common way to light attic rooms. Think of skylight replacement for older extensions due a modern rooflight.
Denton is around 8 km from Manchester, and we survey and fit throughout that part of Greater Manchester, including the M34 district.

Planning, building control and Denton
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.
Read the planning permission guide before you commit to a design.
