What do rooflight upstands & kerbs in Wokingham involve?
Rooflight upstands & kerbs in Wokingham means insulated kerbs built and waterproofed to suit your rooflight. We cover the RG40 district and the rest of Berkshire, with a survey before any price is fixed.
Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice. Rooflight upstands & kerbs suit roofs where the old kerb is low, cold or leaking.
Jobs in Wokingham 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 Wokingham
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. 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. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.
Read the planning permission guide before you commit to a design.

Questions about rooflight upstands & kerbs in Wokingham
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.
Why is my rooflight cold around the edge?
Usually an uninsulated upstand. Insulating the kerb and lining the reveal fixes most cold spots.
Is the survey in Wokingham free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
