In the great scheme we are about to build a shed then take down a garage (have to do it that way because the garage is full and the contents need to go in the shed before we can take it down).
However the garage is roofed with these really nice tiles which match the house and it would be good to re-use these on the shed roof.
However, we need to have both buildings up for a while so we can't use the tiles from the garage when we first build the shed.
Is there something cheap which would last a couple of years as a sloping roof before replacement (or possibly even remaining as a layer under the tiles)?
We were going to use corrugated felt stuff but it would be nice to re-use the tiles.
Do you need to move everything out of the garage if it's going to be rebuilt in the same place?
When we built our new garage we had nowhere to put the contents - which filled the space. We built the new walls and roof round the old then took down the old walls from inside. It worked beautifully.
cheap shed roofng felt sounds perfect. I expect one layer might be enough for 2 years, projects often drag on though
For all those who suggested roofing felt........
..Felted roof goes on wood (planks or ply) goes on rafters. You use felting nails to hold the felt down. You may put battens across the top for additional 'hold down'.
..Tile roof goes on battens goes on rafters. You may have some tar paper or similar beneath the battens.
So unless I am to stretch the felt over some battens (which is not the usual method) this does not seem an obvious solution. I think I am looking for some really cheap material which will keep the rain out for a couple of years and may not need stripping off afterwards.
If the answer is to put on a wood roof covered with roofing felt (standard for sheds), then put battens over the whole thing and put tiles on top, then that might be an option but again may not hit the 'cheap' button.
It is, and (apart from the roofing felt) is how roofs are constructed in Scotland, with sarking boards.
Have the tiles to be laid on battens or could they be nailed to sarking boards?
Using sarking boards strengthens the roof so you might save a bit on rafters, and something cheap like OSB off building site hoardings might be good enough. And would mean you could have a nice weatherproof loft to the shed.
With you up to the loft bit. This is a single pitch sloping roof not an apex roof.
I expect to use reasonable depth rafters so I can get some insulation up between them. I am limited on total height by the current regulations - at least by the dimensions I have to meet if I don't require buildings regulations approval.
Board over the rafters should help weather and draft proofing but is an extra layer with extra cost.
Tiles are big sod off wavy things with a lip at the top to hook over a batten. This lip has a nail hole at right angles to the main tile i.e. you nail it through the lip into the side of the batten with the nail parallel to the main tile. As far as I can see I have to use battens or the tiles will not lie right.
Can you get second hand OSB? Or is the new stuff cheap enough?
2440 * 1220 (8' * 4') for £18.56 at B&Q
Coroline in £183.99 for 15 sheets of 2m * 950mm (effectively 2000 * 750 when you allow for the 200mm overlap).
Calculator tells me that coverage by OSB is 1.984533333 times that of the Coroline.
2 sheets of Coraline cost £24.53.
Hmmm.....18mm OSB is cheaper than Coroline and probably more robust - have to pay for the roofing felt as well but a felted roof on OSB should come in as cheap as a Coroline roof.
When the tiles come free, I then get a tiled roof over the felt which should last a lot longer than a felt roof!
Looks like a plan - but can anyone come up with something even cheaper?
Cheers

P.S. just checked on sarking boards and it says you can lay the insulation on top of the sarking then lay the tiles on that. Not sure about this - might be too fancy for a simple shed.
Use 1/2" chipboard under the felt rather than ply, its very cheap and is fine for 10yrs. At tiling time its easy to knock it off. The downside with chip versus ply is that once the felt leaks, the chip doesnt last long.
It's skipped when site hoardings or shuutering are taken down
11mm stuff is =A39.97 at Wickes. 18mm is =A318.56. Would the thinner stuff do?
18mm is =A316.25 at GG Timber, and =A319.95 at Chiltern Timber, don't know if that's cheaper, it might not incl VAT.
And it's easier to lay the tiles because you've got a fairly solid roof to walk on, and you don't have to take the old roof off before tiling.

Are you in England or Wales, or Scotland (or NI, IoM, or the CI)? If E&W, then you may be confusing Planning and Building Regulations. B/Regs don't care about the height; you can build a shed as tall as Canary Wharf, but provided it's a single storey building with a floor area of no more than 30m^2 and no sleeping accommodation, it's exempt.
According to my information the maximum area before building regs comes in is accompanied by a maximum height. Logical, really - a single storey light house in your back garden might unreasonably annoy the neighbours.
e.g. from

"It is not more than 3m high for a flat roof, or 4m with a ridged roof." Don't think this site is fully up to date, though.

looks a better bet. "#Outbuildings and garages to be single storey with maximum eaves height of
2.5 metres and maximum overall height of four metres with a dual pitched roof or three metres for any other roof. #Maximum height of 2.5 metres in the case of a building, enclosure or container within two metres of a boundary of the curtilage of the dwellinghouse. #No verandas, balconies or raised platforms."
Also, 15m^2 max. if within 0.5m of a boundary unless built from mainly non-flammable materials.
As I will be building within 2m of the boundary I am limited to a maximum height of 2.5m - 0.5m higher than maximum fence height.
It'll do two years easy, our shed roof got re-felted when this happened to the shed:

's over 4 years ago and the weather up here is a bit more extreme than most places. Ordinary single layer of Marley Shed Roof Felt. It is well nailed down though every 1.5" along exposed edges and about every 4" on the covered ones.
The roof that was on in April 2005 was put on after this:

Not sure how long after but would have been early 2000, it was still in good waterproof condition in April 2005.
Did I say we get extreme weather?
For the price of a couple of sheets of OSB (I wouldn't use chipboard or ply, the latter would hard work banging felt nails into) it strikes me as cheap. The battens you'll need anyway and the OSB/felt roof and just be battened over and tiled. You'll then have a roof that will last for donky's years.
OSB can sometimes be obtained from building sites that are nearing completion. It's used as the perimeter fencing and is just chucked when the fence is no longer required.
To make a bigger garage or, especially in our case, to replace an old wooden construction (using Singer Sewing Machine Co packing cases) with a concrete block structure. As a garage there would have been no point in putting it elsewhere, a car wouldn't have been able to reach it :-) As it is, it's used as a workshop and still in the most convenient place. The car lives in the drive.
It won't be a barn dance anyway ... more likely an indoor/outdoor day- long drop-in celebration feast with mediaeval food being cooked outdoors (not a barbecue) by someone who does it for Hampton Court. And lots of champagne ...
If wet we'll erect the Viking tent and various other shelters - the Scout Hut is too far away.
Music provided by family and friends playing double bass, guitar, flutes and several period instruments - all offers accepted - it would be nice to have Scots or Northumbrian pipes.
