Conservation rooflights in Belfast: what is involved?
We handle conservation rooflights across County Antrim, including Belfast. In short: slim, low-profile steel-look rooflights for period and listed roofs. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Wind and rain off the Atlantic make upstand and flashing details important on Northern Irish roofs. Conservation rooflights suit slate and plain-tile roofs where a quiet roofline matters.
We cover all of Belfast and the BT1 district, and nearby Castlereagh and Newtownabbey.

Planning, building control and Belfast
In Northern Ireland, roof alterations come under Class B of the 2015 order: a rooflight facing a road must not project more than 15 cm and must sit at least 0.5 m from the ridge, eaves, verge and party wall. Listed buildings also need listed building consent from the council.
Northern Ireland's energy rules assess rooflight U-values in the vertical position — unlike England and Wales — and expect 1.6 W/m²K or Band C for replacements. New dwellings must average 1.40 W/m²K across windows, roof windows and rooflights.
Read the planning permission guide before you commit to a design.
