How we approach dome rooflights in Seaham
Thinking about dome rooflights in Seaham? The short answer: polycarbonate and acrylic domes for flat roofs, new or replacement. The longer answer depends on your roof, which is why we survey before we price.
Stone villages inland in the North East can have conservation areas where low-profile rooflights are preferred. In Seaham, as anywhere, dome rooflights are the usual choice for schools, flats and commercial flat roofs.
We work across Durham, including Seaham, and in neighbouring towns such as Houghton-le-Spring and Sunderland. Access, parking and how the glass reaches the roof are all checked at the survey.
Specification options
- Polycarbonate or acrylic
- Insulated PVC or GRP upstands
- Twin, triple or quad skin
- Fall-through protection mesh
- Fixed or hinged with vent
- Light, impact-resistant domes
- Quick replacement on existing upstands
Before you order: points to check
- Plastic domes have a lower acoustic and thermal performance than glass
- Upstand condition decides whether you replace dome only or the whole unit
Building control and safety duties in Seaham
On commercial roofs the main questions are usually building control, fire classification of rooflight materials and safe access rather than householder permitted development. 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. Fragile-roof safety and access are planned before work starts.
Read the planning permission guide before you commit to a design.

Dome rooflights in Seaham: 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.
Do domes leak?
Leaks are usually at the upstand seal or the membrane. Replacing the dome and resealing often fixes it.
Are domes safe to walk on?
No. Treat any rooflight as fragile unless it is specifically certified non-fragile, and never stand on it.
How do I book a survey in Seaham?
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 Seaham?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
