How we approach dome rooflights in Bangor, Gwynedd
Our dome rooflights service in Bangor, Gwynedd covers polycarbonate and acrylic domes for flat roofs, new or replacement. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Wales sees a lot of wind-driven rain, particularly in the west, so upstand height and flashing laps matter more than anywhere. Dome rooflights suit older flat roofs with yellowed or leaking domes.
Bangor, Gwynedd is the main town we list in Gwynedd; we also cover nearby Llangefni and Caernarfon.

Common 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.
Can domes open?
Hinged and vented domes are available, manual or electric.
