What do bespoke & shaped rooflights in Lisburn involve?
Our bespoke & shaped rooflights service in Lisburn covers triangular, angled, curved and multi-pane rooflights made to measure. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Wind and rain off the Atlantic make upstand and flashing details important on Northern Irish roofs. Typical uses for bespoke & shaped rooflights include angled ceilings, corners and architect-designed extensions.
We work across County Antrim, including Lisburn, and in neighbouring towns such as Belfast and Castlereagh. Access, parking and how the glass reaches the roof are all checked at the survey.

Do you need permission in Lisburn?
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.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
Can any shape be made?
Most straight-edged shapes can be made in glass, within the manufacturer's size and angle limits. Curved glass is possible but specialist.
Why does bespoke take longer?
Each unit is drawn, checked and manufactured to order.
Can bespoke units open?
Some can. Shaped glass is usually fixed, combined with a standard opening unit elsewhere.
Is the survey in Lisburn free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
How do I book a survey in Lisburn?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
