What are bespoke & shaped rooflights?
Our bespoke & shaped rooflights service in Cumbria covers triangular, angled, curved and multi-pane rooflights made to measure. We survey every job before fixing the price.
Rear kitchen extensions on North West semis often have small domes from decades ago that leak or have yellowed. Converted mills and warehouses in the North West often have large rooflights or glass roofs that need specialist replacement.

Planning and building rules in England
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. 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. 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.

How the job runs
- Tell us about the roof. Send the postcode, rough sizes and a photo or two through the form, WhatsApp or the guide-price tool.
- Free survey. For new installations a surveyor measures the opening, checks the roof build-up and talks through glass and options.
- Fixed written quote. You get the product, the work and the price in writing. Nothing is ordered or paid for until you agree.
- Fitting and handover. We fit, seal and make good, then hand over product data, warranties and any certificate paperwork.

Common questions
Why does bespoke take longer?
Each unit is drawn, checked and manufactured to order.
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.
Do I need to be at home for the survey in Cumbria?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
