Rooflight upstands & kerbs in Magherafelt: what is involved?
Rooflight upstands & kerbs in Magherafelt means insulated kerbs built and waterproofed to suit your rooflight. We cover the BT45 district and the rest of County Londonderry, with a survey before any price is fixed.
Many Northern Irish homes have later flat-roofed kitchen extensions where an old dome can be swapped for glass. Typical uses for rooflight upstands & kerbs include new flat-roof openings and rooflight replacements.
Jobs in Magherafelt 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.

Planning and building rules for Magherafelt
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. 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.
For homes in Northern Ireland, Technical Booklet F1 sets 1.6 W/m²K (or WER Band C) for replacement glazing including rooflights. 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 Magherafelt
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.
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.
Will I need planning permission in Magherafelt?
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.
Can you work alongside my builder in Magherafelt?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
