Replacing shed roof

ginvzt

Our shed is in need of repair. I have been thinking that we will be getting someone to do the job, as neither of us is brilliant in diy, plus OH hates it. To add to this, the shed is quite big (10' x 8'), in an awkward location (backs to the fence and one side is next to the garage, so not an easy access. But yesterday OH said that we could try and do it ourselves!

We knew we will be sorting it out in the next few months, as it has been leaking this winter (and before, but the then landlord didn't consider fixing it, and since we bought the place now, it is up to us to sort it out). And yesterday the felt has been torn off on one side and no the rotten roof boards are exposed to more rain, which started yesterday afternoon!

I think all the boards will need to be replaced, plus the wood planks on either side of the roof (I don't know how these are called). What is the best way to tackle this? I know we can get rolls of felt from B&Q - is it worth getting the more expensive stuff, or just go with the 'value' one? The 8m that come in the super one wouldn't be enough, so we would have to get two rolls, which adds up to the price. I have seen the roofing shingles on Wickes website, which look nice, but work out quite a bit more expensive.

Is there anything else I need to look out that may need to be replaced?

Are OSB boards the way forward to replace the rotted planks? And then I just put on the felt and nail it or glue it down? (how is it supposed to be?) Do I need any underlay or anything else to make it waterproof? There is electricity in the shed (light+heater).

It is a wooden shed, insulated on the inside, as was used as a workroom for one of the previous owners daughters a while ago.

I am at work now, so can't take photos, but will try and do so tonight.

use OSB 8x4 sheets from wickes. cheapest way of doing it.
pick up a leaflet from wickes about flat roofs. itll explain it all to you.

dont go mad spending a fortune on a tin pot shed roof. youll have to do it again every 5 yrs or so anyways.

Thanks ormus. A trip to Wickes and B&Q in order.

The only issue - 8x4 is not that small - will have to think how to bring them home!!!!

ormus

roof rack?
or they will deliver for a small fee.

ps.
BQ will cut them down for you.
(the superstores).

What thickness of the OSB board should be used? I can see that b&Q has them in 9, 11, 15 and 18mm.

personnaly I would go for something like this

far better than timber and felt IMHO

and probably easier to get a watertight fit

I hope someone can help with a similar query...the tarpaulin has come off the middle section of my 10yo 8'(w) x 6'(d) wooden shed. I bought a generic version of "No More Nails" to re-fix this section but couldn't reach anywhere near the rear, so have just secured it with bricks for now, which is unsatisfactory to say the least. So it looks like I am going to have to call in a man with a big ladder to do the job for me.

If I were to have the roof re-covered professionally how much should this cost? The timber appears to be in good condition.
