How we approach rooflight upstands & kerbs in Wigan
For Wigan homes and buildings we offer rooflight upstands & kerbs: insulated kerbs built and waterproofed to suit your rooflight. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
The North West gets more rain than most of England, so upstand height, membrane detailing and rain sensors on opening units are not optional extras. Typical uses for rooflight upstands & kerbs include roofs where the old kerb is low, cold or leaking.
From Wigan to Hindley, Ashton-in-Makerfield and Westhoughton, the same survey-first process applies: measure, specify, fix the price, then fit.
Options we can specify in Wigan
- Timber upstands with insulation
- Upstands to suit single-ply, felt, GRP or liquid roofs

Planning, building control and Wigan
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. 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.
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. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about rooflight upstands & kerbs in Wigan
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.
Can an old upstand be reused?
If it is sound, square, insulated and the right size. Often it is cheaper to rebuild than adapt.
Can I build the upstand myself?
Your builder can, to our drawing. We check it before the rooflight is fitted, because the unit must sit square and level.
Is the survey in Wigan free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
How do I book a survey in Wigan?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
