Hi All,

Have a flat roof at present on an 18m2 extension. The flat roof is in need of some maintenance now, but instead of recovering etc., Im considering replacing it with a pitch roof (Hip type probably to avoid impact neighbours). The extension is block built and structurally sound. I'm just wondering what would the rough cost per square meter for the job be. Trying to put together a rough costing for a number of jobs that need doing.

I will be getting 3+ quotes closer to the time, just trying to build up the outline cost. Have a couple of threads up here on different items.

Thanks in advance,

Rob
 
As far as I can tell from my reading of the planning requirements I dont think so - i.e. under the floor area size, no material change, rear of house etc. I have read the planning act, and specifically schedule 2 - exempted development. Note: Its a single storey extension, 100% to the rear and not visible from the front.

Saying that i will explore this properly before I go further and contact the planning office etc. At this point in time just trying to cost up various elements.
 
Can't help with costs, but ensure whatever covering material is chosen is certified to perform at the angle you can achieve. You're likely to be restricted to a low pitch due to upstairs windows, and low pitches can be problematic in terms of leaks.
 
Many thanks for this. Would I be better off keeping the flat roof or installing a low pitch roof? Which are less problematic?

From an aesthetics point of view the pitch roof will look better both internally and externally in my opinion.
 
Low pitch with the right product will be better. It's more expensive than the basic felt covered flat roof, and that's why most small extensions go with the flat option. There are a number of metal sheeting options (example) that look like tiles that will work with a pitch as low as 10 degrees.

My kitchen extension has a hipped pitch roof, with wooden cladding internally and it really helps make a small extension seem more spacious.
 
Did you consider fibreglass for the flat roof?I got a felted flat roof replaced with fibreglass and it has not leaked and also looks good.
