How we approach rooflight upstands & kerbs in Ashton-under-Lyne
We handle rooflight upstands & kerbs across Greater Manchester, including Ashton-under-Lyne. In short: insulated kerbs built and waterproofed to suit your rooflight. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Converted mills and warehouses in the North West often have large rooflights or glass roofs that need specialist replacement. Rooflight upstands & kerbs suit new flat-roof openings and rooflight replacements.
From Ashton-under-Lyne to Dukinfield, Stalybridge and Droylsden, the same survey-first process applies: measure, specify, fix the price, then fit.

Do you need permission in Ashton-under-Lyne?
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. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.
Read the planning permission guide before you commit to a design.

Rooflight upstands & kerbs in Ashton-under-Lyne: questions
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.
Does every rooflight need an upstand?
Flat and dome rooflights do. Pitched roof windows use flashing kits instead.
Can you work alongside my builder in Ashton-under-Lyne?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Will I need planning permission in Ashton-under-Lyne?
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.
