Any recommendations for roofing felt for a shed?
It will have a new ply roof, so it's a question of what to put on it.
I'm after something better than shed felt, which usually ends up in
the middle of the lawn a couple of years later, but I'm not going to
torch on felt with buckets of molten bitumen, so something inbetween.
How good is the cold tar-like felt adhesive? Can you use it to put on
more than one layer of felt?

Torch on does not require buckets of bitumen. You just need to cut to
length, roll it up and then heat it with a torch as you unroll it. Its
pretty much all I use for any felting these days. If you get the
rubberised "modified" bitumen its pretty tough and durable stuff.
No, it already bonded to the back of the felt.
Play the heat across the back of the felt, (it has a plastic film which
disperses), and partly on the roof... sticks like the proverbial to the
blanket. Fixed as soon as it is cooled, and no titting about with cans
of messy black gloop.
One where you can stick a bigger head on it - say inch and a half to 2
inch. The big long handled torches help, but are not essential for small
areas like a shed.
Never tried a self adhesive felt so can't really comment. The torch on
systems are as good as traditional hot pour system IMHO. Butyl liners
may give you a longer life still, but are a bit more tricky to apply.
Yup, for smaller sections I use something like:
with one of the larger two heads on it, running of a small 4.7kg propane
However, something like:
is cheap enough to buy for the job...
Well went into local builders merchant this morning and came away with a
couple of rolls of IKO Coldseal
Having compared it to the torch on stuff that they had I decided that
given the size and shape (there are upturns on two sides) of the roof it
was probably the better option; less trying to heat and unroll precut
pieces around bends.
Weather permitting I will put it on tomorrow and let you know how I get on.
Thanks for all the advice.

I've now got permission to use Oduline, or similar, corrugated
bituminised sheet. It's supposed to have a 20 year life... Need to
look closely at the installation instructions, I do have concerns
about the wind getting under it. The wind has taken the whole roof
off and deposited it 25 yards away across the road on another
occasion it's rolled the entire (empty) shed upside down as a
Permission? Is your shed listed or something :-)
My felt has worn out at the nails, I hate these sort of jobs where it
feels you've only just done it and yet it needs doing again. I've done
the battening, and was hoping to fit the Onduline yesterday, but the
weather had other opinions, thankfully I did manage to fit a tarp over
it last night, which has had a couple of drenchings already ...
