What do dome rooflights involve?
Our dome rooflights service in Northumberland covers polycarbonate and acrylic domes for flat roofs, new or replacement. We survey every job before fixing the price.
Coastal exposure along the North East means we look closely at frame finishes and seals. North East terraces and colliery-town housing often have rear offshoots where a rooflight brightens a narrow kitchen.

Planning and building rules in England
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. Fire classification of rooflight materials near boundaries is checked at specification.

How the job runs
- Tell us about the roof. Send the postcode, rough sizes and a photo or two through the form, WhatsApp or the guide-price tool.
- Free survey. For new installations a surveyor measures the opening, checks the roof build-up and talks through glass and options.
- Fixed written quote. You get the product, the work and the price in writing. Nothing is ordered or paid for until you agree.
- Fitting and handover. We fit, seal and make good, then hand over product data, warranties and any certificate paperwork.

Common questions
Can domes open?
Hinged and vented domes are available, manual or electric.
Why has my dome gone yellow?
UV breaks down older plastics over time. Modern domes have UV-protective layers, but all plastics age.
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.
Do you fit dome rooflights across Northumberland?
Yes. We survey and fit dome rooflights across Northumberland, including Blyth, Cramlington, Ashington.
