Skylight replacement in Rochester: what is involved?
Skylight replacement in Rochester means replacing tired domes and failed glass with a modern rooflight. We cover the ME1 district and the rest of Kent, with a survey before any price is fixed.
Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice. In Rochester, as anywhere, skylight replacement is the usual choice for yellowed domes, misted glass and leaking roof windows.
Neighbouring towns include Chatham (2 km) and Strood (2 km). We offer a survey date when we reply to your enquiry.

Do you need permission in Rochester?
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.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.
Read the planning permission guide before you commit to a design.
