What do rooflight upstands & kerbs in Rawtenstall involve?
Thinking about rooflight upstands & kerbs in Rawtenstall? The short answer: insulated kerbs built and waterproofed to suit your rooflight. The longer answer depends on your roof, which is why we survey before we price.
Exposed hillside towns in the North West need flashing and seal details that cope with wind-driven rain. Typical uses for rooflight upstands & kerbs include roofs where the old kerb is low, cold or leaking.
We work across Lancashire, including Rawtenstall, and in neighbouring towns such as Accrington and Bury. Access, parking and how the glass reaches the roof are all checked at the survey.

- Timber upstands with insulation
- Internal plaster-box linings

Do you need permission in Rawtenstall?
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. 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 Rawtenstall
Why is my rooflight cold around the edge?
Usually an uninsulated upstand. Insulating the kerb and lining the reveal fixes most cold spots.
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.
Will I need planning permission in Rawtenstall?
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.
Can you work alongside my builder in Rawtenstall?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
