Flat to pitched roof conversions

If you've patched the same flat roof three times in ten years, you aren't unlucky. You're paying instalments on a job that wants doing once.

A conversion puts a proper pitched roof over the flat one, usually on a lightweight timber frame, finished in slate or tile to match the house. The leaking stops because water runs off instead of sitting.

Where it makes sense

  • Rear extensions and kitchen extensions that have never been right
  • Garages, especially attached ones where a leak gets into the house
  • Dormers
  • Porches and utility rooms
  • Any flat roof where the fall was wrong from the day it was built and can't be economically corrected

What's involved

  1. 1A survey of what's holding the roof up.A pitched roof weighs more than a flat one. The existing walls and lintels have to take it, and that's the first thing we check.
  2. 2The flat covering comes off,back to the deck or joists.
  3. 3A timber frameis built to create the pitch, tied into the existing structure and to the house wall.
  4. 4Battens, breathable membrane and covering,in slate or tile chosen to match the main roof.
  5. 5Leadworkwhere the new roof meets the house wall, plus new flashings, valleys and abutments.
  6. 6Fascias, soffits and gutteringto finish, with the rainwater taken into the existing system.

What you get out of it

It stops leaking permanently.
A pitched roof sheds water. That's the whole point, and it's why almost nobody builds a new house with a flat roof over a habitable room.
It looks like part of the house.
Matched to the main roof, a conversion reads as original rather than as an extension with a lid on.
Insulation gets easier.
With a void above the ceiling there's room to insulate properly, which a shallow flat roof rarely allows. Rooms under converted roofs are usually warmer in winter and cooler in summer.

Planning and building regulations

Most conversions on a rear extension or garage are permitted development, but not all. It depends on the height, the position, and whether the property is listed or in a conservation area.

There are several conservation areas across the patch we cover, including around Skipton and parts of Clitheroe. In those, expect the covering material to be specified rather than chosen, and worth establishing that before you take quotes.

We'll tell you what consent we think you need before you spend anything.

Common questions

The things people ask us

That's the first thing we check, and we'll tell you before you spend anything. Most single-storey extensions built in masonry are fine. Where there's real doubt, it's a question for a structural engineer rather than a roofer, and we'll say so.

Normally yes. There'll be a day or so when the roof is open and covered with sheeting, and we plan that around the weather.

For a while. The sums turn once you're paying for scaffold more than once, or once water has started getting into the structure rather than just the ceiling.

That's the intention, and it's why we match the covering to the main roof rather than using whatever's cheapest. On a slate house the conversion should be slated.
