Flat roof to pitch roof - permission?

[Monkeypeas]

We currently have a flat roof above our existing porch (porch was built as part of the house in the 70s) and plan to change this to a pitched / sloped roof similar to the image.
Imagine a brick porch and no garage.

MANY of our neighbours have had this done in the past (before we lived here) but I’m wondering if this needs planning permission.

Does anyone know? Wen I google it, it suggests pp is needed but on the examples it’s the main roof of the house So is raising the roof line not a small roof above a porch which means I’m not sure.

The planning portal has the details. I think if any of the roof is over 3m you need permission. But if your neighbours all have it then there is precedent and it should be easy.
I did my own diagrams and applied for permission, I think £200 planning and £30 for the site plan from one of the three approved vendors.

Thank you for replying.

Could you share a link to the planning portal you mentioned? My local council has one but on the roof but it only talks about roof lights (helpful).

I’ve checked back through all of the planning records for my road and there is not one planning approval for this type of roof and let’s say out of 50 houses, half of them (including 3 immediate neighbours) have pitched / sloped their roof.

So have none of them requested permission? 🧐

At my last house I had a box bay in gallows brackets and a flat roof which we wanted to change into a full bay with pitched roof. I did a pre-planning thing and needed PP for the roof part. I did my own drawings (with copies of original plans cut up and stuck on with pritt stick then photocopied!) and it went through fine.

We changed our flat garage roof (integral, sticks out the front of the house, like your picture) to a pitched roof. Didn't need planning, but a 'kindly' neighbour notified Building Control at the council whilst the builder was working on it, who came round and let us know we needed Building Regs. It was all very straightforward - an inspection during the construction, and another one on completion. Our builder was v apologetic as he'd told us we didn't need any permissions. His mistake - he went half with us on the fee!

So check out Building Regs as well as planning.

Thank you

Thanks all. Looks like I need to figure the drawings required and get it submitted then

The alteration would fall under Class B, which restricts any roof to the front/principal elevation being raised via PD. You’ll therefore require Planning.

Isn't that relating to a roof being raise above the top height of the roof? (ie making the house 'taller' than it currently is).
We definitely didn't need planning to change our flat roof to pitched (as confirmed by the council, in person, on site, whilst the work was being done).

Nope as that comes under Class B.1(b) and I’m referring to Class B.1(c)...

“any part of the dwellinghouse would, as a result of the works, extend beyond the plane of any existing roof slope which forms the principal elevation of the dwellinghouse and fronts a highway”

Doesn't 'extend beyond the plane of any existing roof slope which forms the principal elevation' mean 'go higher than the existing roof'? Which a garage roof wouldn't. I know for sure that planning wasn't needed when we did ours 7 years ago. But there's never any harm in checking.

@ReviewingTheSituation
Just read the link I posted. The rules are quite clear! The OP has got that now.

The national planning portal is a great resource for any developments you might want to do.

No it does not. Take the example of a front dormer, which sits below the existing ridge. Why do you think that would require Planning if it sits below the ridge?

I don’t know why your particular situation did not require Planning. There may have been different circumstances.

We had 2 flat roofs changed last year, one to pitch and one to mono pitch. We checked with our council and did not need planning, only building control, however neither of these were visible from the road.
Our neighbours have told us they think the house looks loads better now .
