What do rooflight upstands & kerbs in Downpatrick involve?
For Downpatrick homes and buildings we offer rooflight upstands & kerbs: insulated kerbs built and waterproofed to suit your rooflight. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Many Northern Irish homes have later flat-roofed kitchen extensions where an old dome can be swapped for glass. In Downpatrick, as anywhere, rooflight upstands & kerbs are the usual choice for new flat-roof openings and rooflight replacements.
Downpatrick sits about 29 km from Castlereagh and 29 km from Newtownards, and we cover the whole BT30 postcode district and the roads in between.

Do you need permission in Downpatrick?
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. Listed buildings also need listed building consent from the council.
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. Extensions follow a 25% glazing allowance in Technical Booklet F1.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about rooflight upstands & kerbs in Downpatrick
How high should a rooflight upstand be?
High enough to meet the rooflight manufacturer's minimum above the finished roof surface — commonly 150 mm. On roofs with deep finishes, such as green roofs, it needs to be taller.
Does every rooflight need an upstand?
Flat and dome rooflights do. Pitched roof windows use flashing kits instead.
Can I build the upstand myself?
Your builder can, to our drawing. We check it before the rooflight is fitted, because the unit must sit square and level.
Is the survey in Downpatrick free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Can you work alongside my builder in Downpatrick?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
