What do rooflight upstands & kerbs in Limavady involve?
We handle rooflight upstands & kerbs across County Londonderry, including Limavady. In short: insulated kerbs built and waterproofed to suit your rooflight. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Northern Ireland has a mix of terraces, bungalows and rural farmhouses, and rooflights are a common upgrade when extending. Rooflight upstands & kerbs suit roofs where the old kerb is low, cold or leaking.
Jobs in Limavady are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
Specification options
- Proprietary insulated kerbs
- Upstands to suit single-ply, felt, GRP or liquid roofs
- Upstand repairs and rebuilds
- Timber upstands with insulation
- Raised upstands for deep green or ballasted roofs
- Fixings and falls agreed with the rooflight maker
- Built square to the rooflight size
Things we check at survey
- Upstand size must match the unit within a tight tolerance
- Minimum upstand height is set by the rooflight manufacturer — commonly 150 mm above the finished roof
Planning, building control and Limavady
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.

Common questions
What roof coverings do you work with?
Single-ply, EPDM, felt, GRP and liquid-applied systems — or we coordinate with your roofer.
Why is my rooflight cold around the edge?
Usually an uninsulated upstand. Insulating the kerb and lining the reveal fixes most cold spots.
Can an old upstand be reused?
If it is sound, square, insulated and the right size. Often it is cheaper to rebuild than adapt.
