Next to our miniature garden shed is a log store erected by the
previous owners of our house. A simple wooden frame butted up to the
back of a garage supporting a simple roof sloping away from the the
garage wall.

The roof appears to be some particle board (stirling) with a simple
layer of roofing felt. The felt has failed and the board is
approaching the consistency of wet weetabix (other breakfast cereals
are available).

The framework is fine, so I hope to simply put up a new board,
probably with a couple of layers of decent felt.

What board should I use? OSB? WBP ply? Something else?

I wouldn't board and felt it, I'd use (for simplicity) something that
was inherently both strong enough and waterproof. Corrugated asbestos
cement is the traditional one, or these days that probably means
Onduline.

If you do want to board it, OSB is the stuff. However there are a
couple of grades about and most builders merchants only sell the less
water resistant of the two, so check first. OSB is quite resistant to
moisture on its surface, but it does need to have the edges well
protected.

OSB is a popular choice, but use OSB3, not 1 or 2.

What about using some of that clear plastic corrugated roofing
sheeting?

I used it for a covered area I made at the back of our summer house
several years ago, built on to the wind sheltered side and its still
fine. It lets light in and some winter heat from the sun, so maybe
would help logs dry out.

if using onduline (or same from Wickes) pay close attention to the
instructions re spacings of support timbers underneath - it will warp
and sag if not supported sufficiently - I know as my woodstore is
covered with it ....

Lasting well though fairly grim to cut - I used a jigsaw with a large
toothed blade - lots of "tarry bits" kicking about for a while after
building... get the correct "mushroom headed" nails and rubber grommet
washers (Wickes do packs) if you really want to keep the rain out....

Clear plastics never last as well under UV exposure as something
opaque. If it's reachable, the extra brittleness in a few years can
lead to broken panels.

If you want clear, I'd go with twinwall polycarb these days. If you
don't need clear, I wouldn't try and use clear.

Much better transfer speed, but still backwards compatible?

Galvanised corrugated iron. Traditional and you can paint it (after a
few months) if the shininess offends. What's more in 100 years time it
will have rusted away to nothing whereas the clear plastic or the
Onduline or whatever will be in a landfill or a hedge somewhere.

If you paint it with tar varnish every three years, in a 100 years
time it will still be on top of the shed.

From my reading of technical data online, the roof of the store is of
such a low pitch that I doubt I'd get away with Onduline without
putting a decking layer under it - the current framework was built for
board and felt, so only supports the edges, basically.

I think I'll have to go with OSB and felt.

Thanks for the pointers.

Getting felt laid down on the roof? I detect the hand of Samantha.

My roof is about 8 deg. so it had to have a full deck. The dimensions are
such that there's 0.5m overlap vertically, so no chance of water getting
back up that.
The adjoining roof of the same pitch is asbestos cement with about 50mm
overlap and, if kept clear of excessive moss, has never leaked via the
overlap.

Yes, I recognized Samantha's er, hand - I do miss that programme but never
unforget to see if it's on. Thnaks for the link.
