What does skylight replacement in Downpatrick involve?
Skylight replacement in Downpatrick means replacing tired domes and failed glass with a modern rooflight. We cover the BT30 district and the rest of County Down, with a survey before any price is fixed.
Wind and rain off the Atlantic make upstand and flashing details important on Northern Irish roofs. In Downpatrick, as anywhere, skylight replacement is the usual choice for older extensions due a modern rooflight.
Downpatrick is around 37 km from Bangor, County Down, and we survey and fit throughout that part of County Down, including the BT30 district.

Consents for skylight replacement in Downpatrick
Northern Ireland's householder permitted development allows rooflights within limits — no more than 15 cm projection on road-facing slopes and a 0.5 m margin from ridge, eaves and party walls. 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.
See our building regulations guide for U-values, glazing limits and self-certification.
