Rooflight upstands & kerbs in Earley: what is involved?
Thinking about rooflight upstands & kerbs in Earley? The short answer: insulated kerbs built and waterproofed to suit your rooflight. The longer answer depends on your roof, which is why we survey before we price.
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. Rooflight upstands & kerbs suit roofs where the old kerb is low, cold or leaking.
From Earley to Reading, Wokingham and Crowthorne, the same survey-first process applies: measure, specify, fix the price, then fit.
Specification options
- Timber upstands with insulation
- Raised upstands for deep green or ballasted roofs
- Internal plaster-box linings
- Upstands to suit single-ply, felt, GRP or liquid roofs
- Proprietary insulated kerbs
- Built square to the rooflight size
- Correct height above the finished roof
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 Earley?
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.
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.

Rooflight upstands & kerbs in Earley: questions
Can I build the upstand myself?
Your builder can, to our drawing. We check it before the rooflight is fitted, because the unit must sit square and level.
Why is my rooflight cold around the edge?
Usually an uninsulated upstand. Insulating the kerb and lining the reveal fixes most cold spots.
What roof coverings do you work with?
Single-ply, EPDM, felt, GRP and liquid-applied systems — or we coordinate with your roofer.
Will I need planning permission in Earley?
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof.
How do I book a survey in Earley?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
