Rooflight upstands & kerbs for Gosport: the essentials
Rooflight upstands & kerbs in Gosport means insulated kerbs built and waterproofed to suit your rooflight. We cover the PO12 district and the rest of Hampshire, with a survey before any price is fixed.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. Typical uses for rooflight upstands & kerbs include roofs where the old kerb is low, cold or leaking.
From Gosport to Portsmouth, Fareham and Ryde, the same survey-first process applies: measure, specify, fix the price, then fit.

Planning and building rules for Gosport
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. 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.

Rooflight upstands & kerbs in Gosport: questions
Can an old upstand be reused?
If it is sound, square, insulated and the right size. Often it is cheaper to rebuild than adapt.
What roof coverings do you work with?
Single-ply, EPDM, felt, GRP and liquid-applied systems — or we coordinate with your roofer.
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.
Is the survey in Gosport free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
How do I book a survey in Gosport?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
