Dome rooflights in Stevenage: what is involved?
For Stevenage homes and buildings we offer dome rooflights: polycarbonate and acrylic domes for flat roofs, new or replacement. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice. In Stevenage, as anywhere, dome rooflights are the usual choice for older flat roofs with yellowed or leaking domes.
Stevenage is around 31 km from Watford, and we survey and fit throughout that part of Hertfordshire, including the SG1 district.
Specification options
- Insulated PVC or GRP upstands
- Polycarbonate or acrylic
- Fall-through protection mesh
- Twin, triple or quad skin
- Clear, opal or tinted
- Quick replacement on existing upstands
- Fixed, hinged or vented options
Things we check at survey
- Upstand condition decides whether you replace dome only or the whole unit
- Plastic domes have a lower acoustic and thermal performance than glass
Regulations for dome rooflights in Stevenage
For non-domestic buildings, planning depends on the building and its location; building regulations cover thermal performance and the fire classification of rooflights near boundaries. Product data for building control is supplied with every quote.
For buildings other than dwellings, Approved Document L Volume 2 sets limiting U-values of 2.2 W/m²K for rooflights and 3.0 W/m²K for roof ventilators, including smoke vents. Fragile-roof safety and access are planned before work starts.
Read the planning permission guide before you commit to a design.

Common questions
Can domes open?
Hinged and vented domes are available, manual or electric.
Can you replace just the dome?
Yes, if the upstand is sound and the size matches. Otherwise we replace both.
Are domes safe to walk on?
No. Treat any rooflight as fragile unless it is specifically certified non-fragile, and never stand on it.
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.
Do I need to be at home for the survey in Stevenage?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
