How we approach rooflight upstands & kerbs in Dewsbury
Our rooflight upstands & kerbs service in Dewsbury covers insulated kerbs built and waterproofed to suit your rooflight. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Exposed Pennine and coastal towns in Yorkshire need upstand and flashing details built for wind-driven rain. Rooflight upstands & kerbs suit new flat-roof openings and rooflight replacements.
Dewsbury is around 13 km from Leeds, and we survey and fit throughout that part of West Yorkshire, including the WF12 district.
What you can choose
- Raised upstands for deep green or ballasted roofs
- Upstands to suit single-ply, felt, GRP or liquid roofs
- Upstand repairs and rebuilds
- Internal plaster-box linings
- Timber upstands with insulation
- Built square to the rooflight size
- Matched to your roof covering
Things we check at survey
- Insulation continuity around the upstand affects condensation
- Minimum upstand height is set by the rooflight manufacturer — commonly 150 mm above the finished roof
Do you need permission in Dewsbury?
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.

Questions about rooflight upstands & kerbs in Dewsbury
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.
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.
Do I need to be at home for the survey in Dewsbury?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Will I need planning permission in Dewsbury?
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge.
