When I built mine I got a large tarpaulin from Screwfix and screwed it down with battens.
OSB will take a bit of weather and moisture, but I would rather have it covered. |

If your framework is all in place then you'll be surprised how much you can get done in the day. There are many different grades of osb and moisture resistant boards are better. Have you considered breathable roofing felt under your shingles? Perhaps consider using fibreglass too.

Easy to board, and felt in a day. Doesn’t take long once you get started.

I'm not really an expert on roofing, so I'm just making it up as I go really. I've only ever done a couple of sheds before. Not familiar with fibreglass Vs felt. All I know is I want to end up with some nice looking felt shingles. I'd like it to last as well.
I could cover the OSB with tarp temporarily if I need to,. 2007 110 TDCi Station Wagon XS |

Rather than leaving the OSB exposed pre-felt I'd get a roll of 1000 gauge PVC damp proof membrane and use it to cover the work-in-progress. Or use a roofing sheet that doesn't need felt to resist the weather.

^^^ plus one, if it has good pitch, ie water will not pool, then up to a month at max.
It's best to felt it properly asap, patterned tarps will mean holes, water will get in, and get trapped causing more problems. Get it up and covered as quick as you can, but just felt it when it is bone dry.

It's a while since I did any roofing work, the last time I had to abandon the felting due to snow. I did have the foresight to use OSB3 which is moisture resistant. Two tip's, try finding OSB3 that is either tonged and grooved or with a half lap joint and the boards normally have a face or smoother side which the felt should be laid on this will prevent the board cutting into the felt. Don't make old people mad.
We don't like being old in the first place, so it doesn't take much to  us off.

I have used Onduline corrugated bitumen sheet. Easy to cut and fix and can be installed in any weather.
Available from most builders merchants or online. Bit more expensive than felt but lasts much longer. |

Felt is pretty old fashioned these days, much better materials available now, speak to your builders merchant.
I second onduline, we use extensively on the farm. I quite like the look and if well supported underneath with a decent pitch will last year's. The other option is box profile tin, in various colours, to save boarding and felting. Good luck, don't forget photos James

Thanks all, I'll do some research into the alternatives to felt. It does need to be an attractive finish, rather than purely function, as we will be looking down on it from the garden. Hence the leaning towards shingles 2007 110 TDCi Station Wagon XS

Agree with above cedar shingles look and smell great.
If your roof it at a steep enough gradient then leaving un, or part uncovered won’t be a problem. |
