Dome rooflights for Blyth: the essentials
For Blyth 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.
Older flat-roofed extensions in the North East are often due a new roof covering — the right time to upgrade the rooflight too. In Blyth, as anywhere, dome rooflights are the usual choice for older flat roofs with yellowed or leaking domes.
Blyth is the main town we list in Northumberland; we also cover nearby Ashington and Cramlington.
Options we can specify in Blyth
- Twin, triple or quad skin
- Fall-through protection mesh
- Fixed or hinged with vent
- Polycarbonate or acrylic
- Insulated PVC or GRP upstands
- Fixed, hinged or vented options
- Light, impact-resistant domes
Before you order: points to check
- Upstand condition decides whether you replace dome only or the whole unit
- Fire classification matters on some roofs
Building control and safety duties in Blyth
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. We confirm the route for your building before ordering.
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. Fire classification of rooflight materials near boundaries is checked at specification.
Read the planning permission guide before you commit to a design.

Dome rooflights in Blyth: questions
Should I replace a dome or switch to glass?
A dome is cheaper and quick; glass gives a clear view and better performance. On a tight budget, or a commercial roof with many units, domes remain sensible.
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 domes open?
Hinged and vented domes are available, manual or electric.
How do I book a survey in Blyth?
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 Blyth?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
