What do rooflight upstands & kerbs in Oldham involve?
Our rooflight upstands & kerbs service in Oldham 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.
Rear kitchen extensions on North West semis often have small domes from decades ago that leak or have yellowed. Rooflight upstands & kerbs suit new flat-roof openings and rooflight replacements.
Jobs in Oldham 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.

Consents for rooflight upstands & kerbs in Oldham
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.

Rooflight upstands & kerbs in Oldham: questions
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.
Why is my rooflight cold around the edge?
Usually an uninsulated upstand. Insulating the kerb and lining the reveal fixes most cold spots.
Can you work alongside my builder in Oldham?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do I need to be at home for the survey in Oldham?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
