What do conservation rooflights in Llangefni involve?
Thinking about conservation rooflights in Llangefni? The short answer: slim, low-profile steel-look rooflights for period and listed roofs. The longer answer depends on your roof, which is why we survey before we price.
Chapels, barns and farm buildings converted across Wales often need bespoke or conservation-style glass. Conservation rooflights suit slate and plain-tile roofs where a quiet roofline matters.
We work across Gwynedd, including Llangefni, and in neighbouring towns such as Bangor, Gwynedd and Caernarfon. Access, parking and how the glass reaches the roof are all checked at the survey.

Planning and building rules for Llangefni
In Wales a rooflight on a house is usually permitted development if it stands no more than 15 cm proud of the roof, except on protected land such as conservation areas and National Parks, where permission is needed. Listed buildings need listed building consent from the council, and flats have no householder permitted development rights.
In Wales the limiting values are 2.2 W/m²K for a rooflight and 1.4 W/m²K (or WER Band B) for a roof window in an existing house. A revised Welsh Approved Document L takes effect on 4 March 2027; rooflights in new dwellings stay at 2.2 W/m²K.
