This is an ordinary timber garden shed 8' x 10' (2.4m x 3m), the roof is
felt on treated sw boards on 3x2 purlins, a central ridge and a shallow
pitch of maybe 15deg. Very standard cheap wooden shed. Over 20 yrs I
have refelted and half re felted and it's leaking again, and the soffit
boards are totally rotted. The rest of the shed is of no particular
quality, and a a bit wobbly.

I was thinking of covering the roof with something better, hoping to
extend its life and usefulness - what would be good? Onduline?
galvanised steel? plywood and a rubber type sheet? some kind of new
material?

I fitted coroline on mine the first time the felt 'went' the boards were
in good condition, it's lasting very well, but not sure I'd go to the
trouble if the roof was rotten.

Depends what wood is rotten. As I remember it, replacing a rotten roof
panel was easier than the felt.

Similar to you, I have re-felted mine several times, but the water
eventually got in and caused the chipboard roof to bow inwards, eventually
to such an extent, I had to take the roof off completely. I bought a
'Tarpaulin' and covered the frame with it. I have it anchored with large
screw-in hooks fixed through the corner eyelets..........it has held fast
for 3 years so far and is water tight. The overhang edges flap a bit in
the wind, but no problem. I bought 2off 8' x 4' heavy gauge chicken wire
fence sheets to use for support, but didn't need to use them.

Refelted our shed roof at least twice but it never lasts more than
about 5 years before it starts to fail. Bog standard shed roofing
felt, clout nail it down stuff.

Last time it needed doing I put coroline(*) on it that was Sep '16
and it's still water tight and looks almost new. The hard bit was
working out the cutting list to minimise wastage as the ridge to
gutter length was a couple of feet less than a sheet. So every third
lenght you had enough "wastage" to do another length. I think the
shed is 6x8 a 8x10 might not be quite so bad.

That's because bog standard shed felt is crap! I have never been a fan
of nailing through the top coat of felt either.

(If nailing, then nail a nail prep layer on - random pattern. Then bond
undercoat to it, and cap sheet over).

I redid the one here when we moved in 12+ years ago with a couple of
layers of torch-on felt (2mm undercoat, and 4mm mineral finish cap
sheet), and its still perfect (and I would expect it to last at least as
long again!)

Last time it needed doing I put coroline(*) on it that was Sep '16
and it's still water tight and looks almost new. The hard bit was

The only decayed wood afaict is the boards that are totally exposed on
the gable end. I thought it was called a soffit but maybe I am wrong. A
board which is nailed on top of the felt along the edge, and another
vertical one.

He said wobbly does this mean the bottom corners of the uprights are

I've never had any problems with that. Anyway, they're all cut from a
flat continuous steel roll which is fed into the profile machine, then
cut to whatever length is required. So all the ends are cut.

IIRC the cheapest long-lived thing per square foot are the thin steel
plastic coated box profile sheets, but you might have to bodge the
ridge. If the boards are not too bad you could probably fit the sheets
using sticks like **** type cartridge adhesive, and save messing around
with roofing nails or screws.

I have to replace a corruline/onduline pitched roof soon, I shall
probably board it first but have not decided whether to use metal or
corruline. I have come to the conclusion that it is *only* worth using
the corrugated bitumen boards with full boarding underneath. Mine lasted
20 years but a stables that I rent has only lasted 10, owing to sagging
and splitting between rafters and purlins.

my shed roof is full 18mm T&G boarded, I added battens for the coroline
and used their ridge pieces, didn't get on quite so well with their end
pieces, but it looks in good shape ~8 years on, no sagging. It's had
just one very light pressure-washing.

Not in my case. I think the wobbliness is a slightly flimsy construction
combined with some subsidence of the blocks it's sitting on, causing a
little distortion of the whole thing. But hey, it's only a potting shed.

Get them cut to size and delivered, that's what I have always done
- and
I've never found them difficult or awkward to handle.


I was thinking of the standard 6m lengths...


Well, yes, in that case cutting them is a nightmare. Suppliers will
generally cut them to size.

The link rather illustrates another potential point - minimum
length 6ft? Sounds bit long for a typical pitch roof shed? So
then we potentially still have the faff of cutting
it...


It does say 'can be cut to length on request'. My local supplier will
cut them down to less than 1 metre.

How do you stop the cut ends going rusty though ?

I've never had any problems with that. Anyway, they're all cut from a
flat continuous steel roll which is fed into the profile machine, then
cut to whatever length is required. So all the ends are cut.


How do they gain the colours then?


That's how the steel rolls come - when I go to my supplier I see the
rolls lying around in the various colours.

IIRC the cheapest long-lived thing per square foot are the thin steel
plastic coated box profile sheets, but you might have to bodge the
ridge. If the boards are not too bad you could probably fit the sheets
using sticks like **** type cartridge adhesive, and save messing around
with roofing nails or screws.

I have to replace a corruline/onduline pitched roof soon, I shall
probably board it first but have not decided whether to use metal or
corruline. I have come to the conclusion that it is *only* worth using
the corrugated bitumen boards with full boarding underneath. Mine lasted
20 years but a stables that I rent has only lasted 10, owing to sagging
and splitting between rafters and purlins.

Chap next door had his shed roof done with a corrugated sheet that looks
remarkably like the asbestos cement that it replaced. The roofer - he lives
about 150m up the road - reckoned that it'll last about 50 years; the old
roof was about 70 yo but 10 past it's 'best before' date.
I did mine with Onduline about 3 years ago; the lean-to next to it was done
with Onduline about 10 years ago - still OK but showing its age.
The manufacturer claims 15 years if 'maintained' which, so far as I can see,
is not leaving debris, especially moss, on it for too long.
Next time I'll use the corrugated cement board or whatever it is, although
15 years might see me out (or 15 weeks the way things are going atm!).
The pitch on these roofs is about 7 deg. so I used 2m sheets on a 3m roof,
giving nearly 2m overlap (the rest is on the eaves).
Harder material would allow more overhang and that would be better at
keeping rain off the timberwork.
The roofs are fully decked under the Onduline so local pooling isn't an
issue.

On a very similar wooden structure I used 2 8x4 sheets of buffalo board.
No felt, apart from a strip on the apex. Slightly more expensive that
OSB and felt but much easier and will last longer.

Box profile sheets. Cheapish and durable.

They have a coloured polymer coating.
