History: a larger shed with some rotting wood I cut down to an 8x5 shed, I used the old roofing felt knowing it would not last more than a couple of years, 3 years later it has sprung a leak! No surprise.Anyhow at this time of the year the last thing I want to do is refelt it as i would rather wait til spring and a bit warmer. I cant see any obvious tears and suspect maybe where I have hammered in the felt roof nails. To tide it over til spring I have a tin of bitumen paint, is this likely to seal it to get me over the winter? The leak is within a 6 inch x 5 foot strip.
