What do bespoke & shaped rooflights involve?
Across County Londonderry, our bespoke & shaped rooflights work covers triangular, angled, curved and multi-pane rooflights made to measure. Survey first, fixed price second, fitting third.
Bungalows are widespread in Northern Ireland, and sun tunnels or roof windows are an easy way to brighten internal hallways. Conservation areas and listed buildings in Northern Ireland are excluded from householder permitted development, so we check before quoting.

Planning and building rules in Northern Ireland
Most rooflights on houses in Northern Ireland are permitted development under Class B, but not in a conservation area or on a listed building's curtilage. A side-facing window within 15 m of a neighbouring boundary must be obscure-glazed, and non-opening unless the opening part is more than 1.7 m above the floor.
Technical Booklet F1 (2022) asks for replacement windows and rooflights in existing homes to reach WER Band C or a U-value of 1.6 W/m²K, assessed in the vertical position. New dwellings must average 1.40 W/m²K across windows, roof windows and rooflights.

How the job runs
- Tell us about the roof. Send the postcode, rough sizes and a photo or two through the form, WhatsApp or the guide-price tool.
- Free survey. For new installations a surveyor measures the opening, checks the roof build-up and talks through glass and options.
- Fixed written quote. You get the product, the work and the price in writing. Nothing is ordered or paid for until you agree.
- Fitting and handover. We fit, seal and make good, then hand over product data, warranties and any certificate paperwork.

Common questions
Will a shaped rooflight leak more?
Not if detailed properly — corners and junctions just need more care.
Do you need my architect's drawings?
They help. We still survey on site, because built openings rarely match drawings exactly.
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.
Can I cancel a bespoke order?
Made-to-measure goods are excluded from the statutory 14-day cancellation right. As a goodwill gesture you can cancel without charge until we place the order with the manufacturer, and we tell you in writing when that happens.
Do I need to be at home for the survey in County Londonderry?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
