Rooflight upstands & kerbs in Hornchurch: what is involved?
Our rooflight upstands & kerbs service in Hornchurch 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.
Victorian and Edwardian terraces with narrow side returns are typical of much of London, and a glass roof or long flat rooflight is the usual way to keep the back rooms bright once the return is built over. Typical uses for rooflight upstands & kerbs include new flat-roof openings and rooflight replacements.
From Hornchurch to Romford, Dagenham and South Ockendon, the same survey-first process applies: measure, specify, fix the price, then fit.

Planning, building control and Hornchurch
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.
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. 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.
Read the planning permission guide before you commit to a design.

Questions about rooflight upstands & kerbs in Hornchurch
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.
What roof coverings do you work with?
Single-ply, EPDM, felt, GRP and liquid-applied systems — or we coordinate with your roofer.
Does every rooflight need an upstand?
Flat and dome rooflights do. Pitched roof windows use flashing kits instead.
Is the survey in Hornchurch free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Do I need to be at home for the survey in Hornchurch?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
