Skylight replacement in Southport: what is involved?
Thinking about skylight replacement in Southport? The short answer: replacing tired domes and failed glass with a modern rooflight. The longer answer depends on your roof, which is why we survey before we price.
Rear kitchen extensions on North West semis often have small domes from decades ago that leak or have yellowed. In Southport, as anywhere, skylight replacement is the usual choice for yellowed domes, misted glass and leaking roof windows.
Neighbouring towns include Formby (10 km) and Lytham St Annes (11 km). We offer a survey date when we reply to your enquiry.
Choices for your Southport project
- Misted glass unit replacement only
- Dome to flat glass upgrade
- Like-for-like size replacement
- Roof window replacement in pitched roofs
- Fixed to electric opening
- Often reuses the existing opening
- Cures most chronic leaks
Things we check at survey
- Upstand and roof condition decide the scope
- Enlarging the opening changes the structure and may need approval
Do you need permission in Southport?
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. 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.
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.

Common questions
Do I need building regulations approval to replace a rooflight?
