Following on from my shed posts, I decided to try and prevent the mass leakage I am getting on my shed roof to buy some time until Summer. I don't do ANY DIY so anything more than a screwdriver turn is beyond my understanding.

Anyway, yesterday I bravely picked up a roll of sand felt, some clout nails and some felt roof adhesive (which I got all over my hands and had to spend ages getting off with white spirit and washing powder granules, evil stuff).

I literally got on top of my shed, and attended to the leaking side of the apex. (All this terminology is advanced to me and already if you told me I would be using it 6 months ago I would not have believed you). The leaking side has a seam line where the old felt overlapped, some of the nails were loose and the line runs the length of the shed. It is directly laong this line the shed is leaking. When I say leaking, I mean that when it rains outside, it rains inside on this part of the shed. All our stuff was getitng wet. What I have done is cut the felt and lay it downwards from the highest point of the centre of the shed. I have allowed the felt to fold over slightly and down the opposite side so rain can't slip down any gaps at the top. I have laid around 4 sheets with a decent sideways overlap onto each other, all from top of apex and down the leaking side to the edge. I then used a load of clout nails at the top of each sheet and used adhesive to roughly and probably quite poorly fasten what I could of the edges of the sheets. It looks abysmal, and it's an amateur job for sure, however, I have just been out in the pissing rain to find that the shed is not leaking - it's holding and the wet wood inside along the length of the shed is slowly drying despite niagra falls outside.

Is my rough method right and am I likley to find this buys some decent time? My logic is that it can't rain upwards, and other than some condensation which may cause a few damp spots, there is no reason why large mounts of water should be dripping / leaking into the shed getting things wet.

I can provide a picture of my handy work if required...

I must admit I am pretty happy that the desired result has been acheived - this is something I never would have dreamed of doing myself even a few weeks ago, hence the new shed thread.

lol thanks for the replies.

The only reason I chose to run the seams horizontal was because having figured out the weakness was along one of the existing vertical seams, I wanted to totally cover it with no gaps near it. I have overlapped the strips of felt sideways by around half a foot, so there is lot's of overlap.

For a 1st attempt it seems to have worked, just been in the shed, all surfaces bone dry and no drips. The damp beam in the roof will take some weeks to dry but for now, so far so good!

Unless its not horizontal rain that will be fine, are the overlaps glued down?
Kind of - used felt roof adhesive (horrible stuff) and stuck them down.
