A bit of a random question, but can anyone recommend a cheep roofing solution that will last a couple of years.
We moved into a property last year which came with a large garage/workshop 4.5m x 8m + a 5m lean too at the back(with asbestos roof but that's fine). The main roof (4.5m span and 8m long) is supported on 5 roof joists made of 4x2"'s and 2x2" rafters at 22" centres it is then clad in T&G boards to tie it all together before felting. The recent bad weather has started lifting the roofing felt off (which has also been install in vertical strips not horizontally, and by the looks of it there are at least 3 layers of old felt underneath). My original plan was to remove the old roof back to wall plates and put a new pitched roof on, I've now found that parts of the long timber walls are badly rotten at the bottom, where soil has been piled up too high against it for years. The base plate and the bottom few inches of a number of uprights are all rotten. I am planning on pulling it down and rebuilding it completely in a couple of years when time and money permit but, in the meantime it's a godsend for storing my tools/ materials and as a dry space to do stuff while I work on the house.
I've priced up a couple of options, IKO green mineral roofing felt around £300-400, but this will be thrown away in a couple of years. Alternatively i could use the plastic coated metal sheeting 32/1000 box profile around £500-600 and i could reuse it afterwards. Due to the extremely small roof rafters and the spacing between the joists and the fact they have dropped about 5" in the centre, i don't really want to walk on the roof. I'll remove as much of the old felt to reduce the weight on the roof. I'm also concerned about the T&G close boarding underneath being rigid enough to support the felt without it moving and tearing the felt, again ideally new OSB boarding would be best but that's a lot of extra money and weight to put up there. I could add a few new 4x2 or 6x2 trusses in between the existing, but it's all money id prefer to spend on the new building, unless i could reuse some if it? I'd also struggle getting the foot of the new rafter between the wall plate and the T&G boarding, i measured a gap of about 1.5", so i'd have to reduce the size of the end of the new rafter down to 1.5" to fit
A friend did suggest a large tarpaulin and some battening to fix it in place, but I've found the modern woven tarpaulins start to leak after a short while and i'll be no better off.
Any suggestions are very welcome
