What does skylight replacement in Stevenage involve?
For Stevenage homes and buildings we offer skylight replacement: replacing tired domes and failed glass with a modern rooflight. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. Skylight replacement suits yellowed domes, misted glass and leaking roof windows.
Stevenage is around 31 km from Watford, and we survey and fit throughout that part of Hertfordshire, including the SG1 district.
Options we can specify in Stevenage
- Roof window replacement in pitched roofs
- Dome to flat glass upgrade
- Upstand rebuild and insulation

- Misted glass unit replacement only

- Usually done in a day
Before you order: points to check
- Enlarging the opening changes the structure and may need approval
- Upstand and roof condition decide the scope
Consents for skylight replacement in Stevenage
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.
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. 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.

Common questions
What do you do with the old unit?
We remove it from site and recycle what can be recycled.
Can you replace only the misted glass?
Sometimes, if the frame is sound and the maker supplies replacement units. Often a complete new rooflight costs little more and performs better.
Can I go bigger when replacing?
Possibly. Enlarging the opening means trimming joists, so we check the structure first.
How do I book a survey in Stevenage?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Can you work alongside my builder in Stevenage?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
