How we approach rooflight upstands & kerbs in Fareham
We handle rooflight upstands & kerbs across Hampshire, including Fareham. 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.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. Think of rooflight upstands & kerbs for roofs where the old kerb is low, cold or leaking.
From Fareham to Gosport, Portsmouth and Waterlooville, the same survey-first process applies: measure, specify, fix the price, then fit.

Consents for rooflight upstands & kerbs in Fareham
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.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.

Questions about rooflight upstands & kerbs in Fareham
What roof coverings do you work with?
Single-ply, EPDM, felt, GRP and liquid-applied systems — or we coordinate with your roofer.
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.
Can an old upstand be reused?
If it is sound, square, insulated and the right size. Often it is cheaper to rebuild than adapt.
Can you work alongside my builder in Fareham?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Is the survey in Fareham free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
