by mini, i meant short. Stack a bunch of 2x4s on top of each other in the middle of the floor. Use that as your peak. Now the poly will have a shallow slope to each which would promote water runoff and prevent pooling...
I did actually do that, but the frame round the outside acted like a 2" high stop, and wouldnt allow the water to run off out of the shed and still pooled.
I did actually look at tarps and was offered 2 off my friend, but actually simply forgot to go and collect them.
It does have polythene over the top now and i hope to go and buy boards and felt tomorrow, so it should be waterproof (the roof that is) by the weekend.
