Dormer windows in West Yorkshire
West Yorkshire homeowners come to us for dormer windows and dormer loft conversions that are properly detailed at the junctions — because that is where dormers succeed or fail.
Dormers on West Yorkshire roofs
The housing stock around West Yorkshire runs to gritstone and brick terraces, back-to-backs and generous interwar semis — so the first question at survey is always which of those you have, because the structure underneath differs completely.
We survey the roof before quoting anything. Ridge height, rafter span, purlin position and the condition of the existing structure decide which dormer forms are possible — and there is no substitute for a tape measure in the loft. The survey is free and carries no obligation.
Planning permission in West Yorkshire
We run the permitted development test on your specific property: set-back from the eaves, height against the ridge, volume allowance and whether an Article 4 direction applies locally.

Judged on the junctions, not the sales pitch
“The survey was the useful bit — he told us the ridge height wouldn't take what we'd been sold elsewhere, and offered a shed dormer instead. Glad we listened.”
— Homeowner, West Yorkshire“Scaffold went up on the Monday, roof was open and weathertight by the Thursday. No drama, no surprises on the invoice.”
— Homeowner, West Yorkshire“We'd had two leaks patched by other firms. They traced it to the back gutter in an hour and it hasn't come back since.”

FAQs
Dormers in West Yorkshire — FAQs
How much does a dormer window cost?
A single flat roof dormer typically runs from around £9,000 to £20,000 supplied and fitted, depending on width, cladding finish and access. A full-width rear dormer on a semi is usually £28,000 to £45,000, and a complete dormer loft conversion including stairs, insulation, plaster and building control sign-off is more commonly £40,000 to £70,000. Our online guide-price tool gives you an indicative range in about a minute.
Will my roof be open to the weather?
No. The roof is only opened once the scaffold, temporary weather protection and materials are all on site, and the dormer is made weathertight — structure, deck, membrane and temporary glazing — before the crew leaves at the end of the opening-up phase. We do not open a roof on a Friday afternoon.
Can you build a dormer on a bungalow?
Usually yes, and bungalows often give the best results because the spans are wide and there are no party walls. The deciding factor is ridge height: you generally want at least 2.6m from the top of the ceiling joists to the underside of the ridge. We measure this at survey before committing to anything.
Why is my dormer leaking?
In our experience the window itself is the cause less than a fifth of the time. Far more often it is the apron flashing at the dormer front, the lead soakers where the cheeks meet the roof slope, the back gutter behind a pitched dormer, or a split at an upstand in the flat covering. Water then tracks along a rafter and appears somewhere else entirely, which is why we trace the path before quoting.
What insulation do dormers need?
Current building regulations want around 0.15–0.18 W/m²K for a new dormer roof and 0.18 W/m²K for the cheeks and front. In practice that is a warm-roof build-up using 100–150mm of PIR insulation above or between the structure, with a continuous vapour control layer on the warm side. Getting the VCL continuous matters more than the insulation thickness.
Do you handle the planning application?
Yes. We prepare measured drawings, elevations and sections, submit the application or the lawful development certificate, and deal with the case officer's queries. On conservation and listed work we also put together the heritage justification the application needs.
