behind the parapet, is shaped into a trough to conduct the water along
to an outlet. Very fiddly indeed, I'd say. And the flashing is old and
I can already see a split in one place.

In order to avoid the repar, both now and in years to come, I'm
contempating having a sloping tiled roof put on, over the extension.
The dimensions (looking diectly downwards as in a plan drawing) ae
about, 5ft x 15ft. Does anyone have a clue what a builder would charge
to construct that? (So I can decide whether to DIM or just try to
repair the flat roof.)


Flat roofs always go, and when they do they cause reall problems,
whereas a sloped roof at least just leaks a tiny bit.

I'd get a builder to look into a fully tiled one.

It sort of sounds like a couple of grand job to me..
Thanks,

we nad a similar problem when we moved, our extension is about 66' x
8' the flat roof was leaking quite badly, i would of liked a pitched
roof fitting instead, however it needed planing permission so we
decided not to waitand had a grp flat roof fitted (=A32,100). The quote
for the pitched roof was =A34,400 this was by a 2 man operation in North
Yorkshire, as with most things i suppose the cost will vary greatly.
one point i didnt apreciate at the time was how a pitched roof would
have made access to the main house roof difficult
