What do bespoke & shaped rooflights in Farnworth involve?
Thinking about bespoke & shaped rooflights in Farnworth? The short answer: triangular, angled, curved and multi-pane rooflights made to measure. The longer answer depends on your roof, which is why we survey before we price.
The North West gets more rain than most of England, so upstand height, membrane detailing and rain sensors on opening units are not optional extras. In Farnworth, as anywhere, bespoke & shaped rooflights are the usual choice for angled ceilings, corners and architect-designed extensions.
Neighbouring towns include Walkden (4 km) and Bolton (4 km). We offer a survey date when we reply to your enquiry.

Planning, building control and Farnworth
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. 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.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. 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 bespoke & shaped rooflights in Farnworth
Do you need my architect's drawings?
They help. We still survey on site, because built openings rarely match drawings exactly.
Will a shaped rooflight leak more?
Not if detailed properly — corners and junctions just need more care.
Can bespoke units open?
Some can. Shaped glass is usually fixed, combined with a standard opening unit elsewhere.
Can you work alongside my builder in Farnworth?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do I need to be at home for the survey in Farnworth?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
