Lead & Zinc Dormer Roofing in Lincolnshire
We are a dormer specialist, not a general builder who occasionally does roofs — and across Lincolnshire that focus shows up in the detailing.
Lead & Zinc Dormer Roofing — indicative geometry
Lead & Zinc Dormer Roofing for Lincolnshire homes
Lincolnshire is a mix of Victorian and Edwardian terraces, interwar semi-detached houses and post-war bungalows, and each of those wants a different dormer form — which is why we survey before quoting rather than pricing off a photograph.
Lead fails from thermal movement, not from age — which means bay sizes, code thickness and fixing centres decide whether a dormer roof lasts thirty years or three. We work to Lead Sheet Association guidance on every detail: welted bays, correct laps, chase depths and clip spacing. Standing-seam zinc gives a similar lifespan with a lighter, more contemporary line.

Planning and building control in Lincolnshire
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.
Building regulations approval is separate and always required. We submit the application, book the inspections around the programme and hand you the completion certificate at the end — the document a buyer's surveyor will ask to see.
Why homeowners in Lincolnshire use us
We only do dormers. That sounds like a limitation until you have watched a general builder improvise a back gutter on a wet Thursday.
Send us the address and roughly what you are hoping to gain, and we will come back with a realistic answer rather than an optimistic one.

FAQs
Lead & Zinc Dormer Roofing in Lincolnshire — FAQs
Does a dormer need building regulations approval?
Yes, always — permitted development covers planning, not building control. A dormer needs approval for structure, thermal performance under Part L, fire escape and protected route under Part B, and stairs under Part K if a staircase is involved. We handle the application, the inspections and the completion certificate.
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.
Will a dormer add value to my house?
A properly built and signed-off dormer conversion adding a bedroom and bathroom typically returns a meaningful share of its cost in value, and more in areas where floor space is scarce. The building control completion certificate is what makes the space count as habitable floor area on a valuation — without it, surveyors will not include it.
Is scaffolding included in the price?
Yes. Every quotation we issue includes scaffold design, erection, weekly inspection, hire for the programme and dismantling. Scaffold appearing as an extra afterwards is one of the more common complaints about dormer work, so we price it in from the start.
How wide can a dormer be?
Structurally, as wide as the roof — full-width rear dormers regularly run six to eight metres, carried on a steel ridge beam. The limits are usually planning volume allowances and the setbacks needed at eaves and ridge, rather than what can be built.
