Rooflight upstands & kerbs in St Neots: what is involved?
We handle rooflight upstands & kerbs across Cambridgeshire, including St Neots. 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.
Coastal towns in the East of England see salty air, so we specify frame finishes and fixings with exposure in mind. Typical uses for rooflight upstands & kerbs include new flat-roof openings and rooflight replacements.
From St Neots to Sandy, Huntingdon and Biggleswade, the same survey-first process applies: measure, specify, fix the price, then fit.
Options we can specify in St Neots
- Upstands to suit single-ply, felt, GRP or liquid roofs
- Upstand repairs and rebuilds
- Proprietary insulated kerbs
- Timber upstands with insulation
- Internal plaster-box linings
- Fixings and falls agreed with the rooflight maker
- Built square to the rooflight size
Things we check at survey
- Upstand size must match the unit within a tight tolerance
- Membrane compatibility with the rooflight's sealants
Do you need permission in St Neots?
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. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
What roof coverings do you work with?
Single-ply, EPDM, felt, GRP and liquid-applied systems — or we coordinate with your roofer.
Can an old upstand be reused?
If it is sound, square, insulated and the right size. Often it is cheaper to rebuild than adapt.
Does every rooflight need an upstand?
Flat and dome rooflights do. Pitched roof windows use flashing kits instead.
Is the survey in St Neots 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 St Neots?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
