What do rooflight upstands & kerbs in Bicester involve?
Rooflight upstands & kerbs in Bicester means insulated kerbs built and waterproofed to suit your rooflight. We cover the OX26 district and the rest of Oxfordshire, with a survey before any price is fixed.
Larger gardens in much of the South East mean deeper rear extensions, and deeper rooms need light from above rather than only from the doors. Think of rooflight upstands & kerbs for roofs where the old kerb is low, cold or leaking.
From Bicester to Oxford, Banbury and Aylesbury, the same survey-first process applies: measure, specify, fix the price, then fit.

Do you need permission in Bicester?
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. 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. 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.
Read the planning permission guide before you commit to a design.

Common 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.
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 Bicester free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Will I need planning permission in Bicester?
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.
