Dome rooflights in Darlington: what is involved?
Thinking about dome rooflights in Darlington? 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.
Older flat-roofed extensions in the North East are often due a new roof covering — the right time to upgrade the rooflight too. Dome rooflights suit older flat roofs with yellowed or leaking domes.
Darlington is the main town we list in Durham; we also cover nearby Newton Aycliffe and Stockton-on-Tees.

Rules and responsibilities in Darlington
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.

Questions about dome rooflights in Darlington
Do domes leak?
Leaks are usually at the upstand seal or the membrane. Replacing the dome and resealing often fixes it.
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.
How do I book a survey in Darlington?
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 Darlington?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
