Can anyone advise what is the best stuff for sealing a leaky flat
felt-covered roof?

I once used some black bitumous liquid from B&Q, but the leaks
recurred after about 2 or 3 years.

Thank you,

Drake

Or even a new felt covering. This is the minimum solution once they leak.
Factor the cost in your plans for every 10 years.

It really depends on why it's leaking. If a seam etc has failed it can be
repaired. If the felt is crumbling replacement is the only real cure.

Thanks. I saw no signs of crumbling felt when I last applied bitumous
sealing liquid a few years ago. But I'm really not sure where the leak
is, precisely. It could just be a small split that's very hard to
locate. All I know is the roughly 2ft x 2ft area where the leak is
located.

That sounds like a good solution, actually. Thanks...

Yes, I couldn't agree more. My only problem is the cost and time it
would take to construct.

Strip it all off, and re-felt is the only real answer to that question.
If you keep fixing it, there is the problem that you may not stop all of
the leaks. So when you do eventually strip it off you are faced with the
possibility of replacing loads of rotten timber as well (and ceiling
joists if its dry rot you find!).

In spite of its poor reputation, a felt roof can last well if it has a
good solid base and at least three layers of quality felt that are
bonded on with hot tar.

The cost of doing this could exceed several felt roof replacements - even
if it were practical to do so. On many flat roofs - like extensions - it's
not due to windows etc above on the main building.

Flat roofs generally have a poor reputation due to poor design and
construction.

Thanks. I'm sure that would be the most long-lasting solution. But I'm
really just looking for a quick fix that will last at least a few
months. I don't intend to be living here much longer than that.

Yes, the above all applies in my case, as it happens.

I used that bitumen faced Al tape successfully to solve leaks in
several flat roofs. No doubt it has a proper name but it is available
in the sheds.

flashband? (toolstation do a cheaper version - available in a number of
widths)

Have you considered replacing with

Well in that case, and given that you say you know the general area of
the leak. how about a big patch of felt over that area, stuck down with
the paint on bitumen glue type stuff?

Or a roll of "torch on" felt and a big blowtorch. Quick and easy to fix
and that will effect a repair that might even last a few of years.

That sounds like what I need. Thanks. Can you tell me who sells it?
B&Q? Wickes?

Ironic really, as when looking at properties with flat roofs, they are
referred to as 'duck ponds' by surveyors, but I suppose where you find
ducks you find Drakes GGG

Might be in your local DIY shed, any Builders Merchants will sell it
though I imagine. (Note to all felt is suitable for 'torch on'
application)

As for the torch, probably best off hiring one.

They're only ever duck ponds if actually flat. Which is the problem. I can
only assume most builders want the work of replacing badly made ones as it
hardly costs more to put a proper slope on them.

They may. A builders merchant will certainly have it. Price is about 50%
more than ordinary top felt. It helps if you have or hire a *big*
blowtorch, then you can simple heat it and press it on.
