What do rooflight upstands & kerbs in Westbury-on-Trym involve?
For Westbury-on-Trym homes and buildings we offer rooflight upstands & kerbs: insulated kerbs built and waterproofed to suit your rooflight. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Stone cottages, slate roofs and conservation areas are common in the South West, and conservation-profile rooflights keep the roofline quiet. Think of rooflight upstands & kerbs for roofs where the old kerb is low, cold or leaking.
We work across Bristol, including Westbury-on-Trym, and in neighbouring towns such as Redland and Clifton. Access, parking and how the glass reaches the roof are all checked at the survey.

Planning, building control and Westbury-on-Trym
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. 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.

Rooflight upstands & kerbs in Westbury-on-Trym: 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.
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.
Does every rooflight need an upstand?
Flat and dome rooflights do. Pitched roof windows use flashing kits instead.
Can you work alongside my builder in Westbury-on-Trym?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Is the survey in Westbury-on-Trym free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
