Rooflight upstands & kerbs for Feltham: the essentials
Rooflight upstands & kerbs in Feltham means insulated kerbs built and waterproofed to suit your rooflight. We cover the TW13 district and the rest of Greater London, with a survey before any price is fixed.
Many London roofs are reached only through the house or over neighbouring property, so lifting heavy glass is planned at survey rather than on the day. Rooflight upstands & kerbs suit roofs where the old kerb is low, cold or leaking.
Jobs in Feltham 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.
Options we can specify in Feltham
- Upstands to suit single-ply, felt, GRP or liquid roofs
- Upstand repairs and rebuilds

Things we check at survey
- Insulation continuity around the upstand affects condensation
- Minimum upstand height is set by the rooflight manufacturer — commonly 150 mm above the finished roof
Do you need permission in Feltham?
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. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. 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 Feltham
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 an old upstand be reused?
If it is sound, square, insulated and the right size. Often it is cheaper to rebuild than adapt.
Do I need to be at home for the survey in Feltham?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
