Aa some of you might remember that ever since I built my new loft I've had problems with my choice of roof which you may remember is the corrugated bitumen sheets. A couple of years ago I had water coming in through some of the joints which I eventually managed to cure, over the last couple of years the roof has deteriorated and become very disformed with it now sagging in several places which has been a problem on race days if it's been raining as the birds would go to the back of the loft for a drink before trapping. Any after all the rain we have had recently a couple of the sags have gotten even worse so much so that birds can now bath in them and the when full the water is again getting into the loft added to that again due the bad weather a couple of weeks ago I put the winter fronts up, this has now caused me another problem as because the nights have been so mild the humidity in the loft has risen so much that the condensation that is forming on the inside of the sheets is once again soaking the inside of the loft
I know that I need to rectify this asap so in the new year intend to renew the whole roof, as cost is an issue my current plan is to buy 18mm Osb board. Now some of the corrugated sheets I have are possibly still useable so do I use those and buy a couple more to replace the really deformed ones (which is probably the cheapest option) or do I use roofing felt ???
Use board and the current sheets that will return to natural form more or less after being placed on solid surface if any dont then replace the very bad ones
On another note my loft is also very wet due to the weather and have to dry every day

Trev, I would certainly take the corrugated sheets off and put ply on. As it’s the roof with no significant weight on it you could probably get away with 12mm sheets. I would then use roofing felt personally. I don’t know what you would pay for the bitumen sheets but it looks around £19 per sheet. Good roofing felt is around £35 for a 10 metre roll. I seem to think your loft is about 16 feet, you would probably need 2 rolls. Put a decent over hang especially at the back. I have ply and roofing felt on both of mine and have no problems.
Well not until today when the youngsters knocked the top off the drinker and had a bath in it lol. I have also just done the same on the back of the shop, ply and roofing felt! Mine is fully closed in apart from when the traps are open and I get no condensation. Only ventilation is through the roof space on the youngbird loft and through a small gap along the back and front just under the roof of the main loft. I have plenty of spiders and cobwebs in there which I think is a good sign of a dry loft.
Back just enjoying club racing for the time being.

I agree Buster, I think that is my best option. I've watched video clips since using those sheets and alot of people use them on top of osb board.
Sorry to hear you are having problems too although its also good to know it's not just me, this mild and damp weather isn't good for the birds.

I will certainly look into that as an option as well Andy Funny thing with the cobwebs though is that I have loads of them in my feed store section but it's still soaking wet in there too !!! Just had a quick look at the price of Ply versus OSB and I see there isn't much difference and also felt prices seem to have come down a bit.

Sorry I meant OSB for the roof.

Thing with felt it needs replacing every few years the corrugated sheets are almost permanent, I do remember saying to you at the time it would sag eventually with no support under it
one of my lofts is felt the newer one I used the sheets on and that is perfect but the felt has gone white and brittle, the only thing stopping me sheeting it is the cost of the roof pieces as the roof is like an ''A'' shape the front couple feet slopes down so that will have to be felted but with my health conditions can no longer get on roof to do it so will have to stay until can get somebody to help me

You do need to get good quality roofing felt. I brought the rhino flex. Should last 15/20 years. The felt on my young bird loft is now 7 years old and still looks as good as new. Even took it up and relayed it when I moved the loft. It is best to use bitumen sealer along the joins. I can see the advantage to using the corrugated sheets though.

I would put the OSB over as a ceiling. Nail down well all around. Then lay 2x2 or 3x2 or whatever stock sizes you have over there, the length of the shed, one at the front, one at the back and one in the middle. Nail the outside ones down and put screws up from underneath in the middle. That is now rigid.
Screw your sheets down into those battens. That will not sag.
I hate flat roofs.

Buster, you have mentioned before that your lofts get wet. Why is that?
Is the roof leaking or is the rain getting in elsewhere?
Just wondering.
