Pitched Roof Dormers in Kent
From the first measured survey to the completion certificate, we run pitched roof dormers projects in Kent as a single, managed piece of work.
Pitched Roof Dormers — indicative geometry
Pitched Roof Dormers for Kent homes
The housing stock around Kent runs to Victorian and Edwardian villas, weatherboarded cottages and large 1930s semi-detached estates — so the first question at survey is always which of those you have, because the structure underneath differs completely.
A pitched roof dormer carries its own small ridge and two slopes, tiled or slated to match the main roof. It sheds water the way the rest of the house does, ages the same way, and is very often the only form a conservation officer will accept on a front elevation. You lose a little internal height at the head compared with a flat top, and you gain a roofline that nobody questions.
Key specification
| Typical projection | 1.2m – 3.0m wide |
|---|---|
| Pitch | 35° – 45°, usually matched to main roof |
| Roof finish | Plain tile, pantile or natural slate |
| Flashing | Code 4/5 lead soakers and back gutter |
Planning and building control in Kent
Whether you need planning permission or a lawful development certificate depends on the elevation, the volume already used and the local authority's Article 4 position — all of which we confirm before design work starts.
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 Kent use us
One quotation covers scaffold, structure, weatherproofing, glazing, plastering and sign-off. You are not coordinating four trades who each blame the last one.
Book the survey, get the fixed written price, and decide in your own time. Nothing about that process commits you to anything.

FAQs
Pitched Roof Dormers in Kent — FAQs
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.
Can I put a dormer on the front of my house?
Front-facing dormers are not covered by permitted development and always need a full planning application. Approval depends heavily on the street scene — planners look at whether other dormers already exist on the road, and at proportion, position and materials. Hipped and pitched forms are approved far more often than flat boxes on a front elevation.
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.
What is the difference between a dormer and a Velux?
A rooflight sits flush in the roof slope and gives you light without any extra height — you still have a sloping ceiling. A dormer projects out from the roof and creates vertical walls with a level ceiling behind them, so you gain genuinely usable standing space and floor area, not just daylight.
Do you work on listed buildings and in conservation areas?
Yes. That work is detail-led: matching sightlines, glazing bar widths, cill projections and cheek finishes to what survives, and specifying timber, lead and natural slate rather than modern equivalents. We prepare the drawings and heritage statement for listed building consent alongside the planning application.
