Hi all,
I have just finished building my 14ft x 10ft shed it has a double
layer felt roof but i still get water comeing in and i have looked for
a gap in the felt but can not see where its coming from, it has a
8inch slope on it, so instead of refelting would it be possible to
cover the roof in hot bitumen? As this might be the cheaper option as
a burner from hss is only £15 any ideas how much the bitumen is ? as i
notice BQ do a aquaseal roof repair 5 litres for £15, ideas or
suggestions please.

What sort of quality is the felt?
Some of the "shed" quality felt I've seen is so porous as to be
virtually worthless.

Our shed has torch-on felt, why I don't know - it was like it when we
bought the place, but it has never leaked in the last 9 years.
Unlike the main house roof, which has ;(

Doesn't sound like much of fall for that area, basically flat.
Capillary action is probably drawing water between the layers.

Don't get any water through the shed roof I did a couple of years
back. But it is a "traditional" 6x8 shed with a proper pitched roof.
Single layer of bog standard Marely "Shed Roof Felt", all exposed
edges clout nailed at 2" intervals. Withstood the F9 Severe Gale,
gusting to the mid 50's mph no problem, it's survived other gales as
well.

Whilst I don't have experience of the material used for roofing
purposes I wonder if glass fibre might be a better option?

Felt roofs have always proved troublesome in my experience. If I had
to do another flat roof project I'd certainly consider glass fibre as
an option.

Is it water from outside, or is it condensation building up inside the roof space ?

Definately water from outside, sorry the fall on the roof is 14inch

If you can't see any obvious holes, then the most next likely cause is capillary action through one of the
seams in the felt. Paint some liquid bitumen along the seams and it should help.
