I have a flat roof on my workshop, and since felting it some months ago, the felt has lifted and crinkled in places and is holding water in said crinkles which is now finding it's way through the joints and into the workshop,
I've just been up on the roof and tried to pour felt goop onto the joints to try and slow it down, but the whole roof looks really crinkled now. I laid this in the summer when it was warm, and if anything would have expected the felt to shrink and contract as it got colder, but it seems the revers is true and as a result it's folding and crinkling.
Short of taking it all off and starting again, anyone got a quick and relatively cheap method of repair?
Had thought about trying to find someone with a tar boiler and simply pouring tar along all the joints, but for one, I don't know anyone with a tar boiler, and my local hire shop don't hire them.
Anyone care to offer some much needed advice before my new baby gets soggy.........
