About straighetening of the roof

pieroabcd

Hi,
being in search of a house to buy and having viewed many, I've always wondered  if it would be possible to straighten the roof, that in all my cases was sloping on one or  two sides. I've also noticed that it's always much lower than the ceiling in the lower floors (around 2-2.10 m).
Given a proper engineering plan, would the straightening be approved by the council and by the lender (for the mortgage)? Any idea of would much would it cost to make it totally flat and as high as the lower floors (at least 2.60m) assuming an area of 25 sqm?
Or maybe keeping it sloping, but with a much higher aperture, like 150-160 degrees in order to keep the side still high?

Thanks.

Don't know what you mean by "straighten". Some pictures might help.

I mean making it totally flat and horizontal, without sloping parts

or maybe like the one on the smaller building, that has a lower pitch.

What's the reason for doing it ? 🤔

A loft conversion?

A totally flat roof is asking for trouble as water likes to make its way downwards.

They are already loft conversions, being used and furnished as bedrooms.  The idea is to have much more space available.

It can be done, where the house is and what neighbouring properties look like will be factors in the chances of PP success. However unless buying in a very expensive area I can't see it being cost effective, you'd be putting on a completely new roof when the old one is still serviceable. On top of that, I agree with other replies: houses in this country tend to have a decent pitch for good reason!

You want to buy a house with a pitch roof, and convert it to a flat roof.

Yes, it's possible.
Yes, you'll need planning permission and building regs.
Yes, it'll be bloody expensive.
No, it won't increase upstairs ceiling height unless you increase the height of the walls.

And all for a cosmetic difference that most people with experience of flat roofs would prefer to avoid...

Wouldn't it just be easier to buy a house that you like the look of?

Of course, if I found it! :-)

There are new builds, yes, but they are so far away from where I work that the cost of the season ticket would defeat the advantage of owning a house, not to speak of the backpain and the tiredness of commuting every day for 2.5 hours.

Anyway, it wouldn't be just a cosmetic difference: hitting the head against the roof every time that you try to move in the room is quite substantial, like not having enough hight for a cupboard or sweltering in summer because of the heat. Of course the walls would need raising, that goes without saying.

Thanks everyone for answering.
