Felt for shed - talk to me
Discussion
Yes there are,normally rated by years of life.
Cheap shed roof felt is generally carp and won't last long. I just used two layers of Wickes Traditional Underlay and 1 layer of traditional roofing felt. The cheap stuff didn't look like it would last ten minutes.
This is onto a sloping roof of a brick built shed, with a 5-10 degree incline. Deck consisted of (Replaced) joists of 2x4 with 11mm OSB3 ontop (I should have gone for 18mm, 11mm flexes a LOT when you walk on it, which you have to do with a flat roof!)
Nail the first layer of underlay to the deck, then tar ontop the next layer, and then tar on the top layer. I used cold set bitumen paint type adhesive. Don't have joints which overlap directly (I laid the intermediate underlay layer at right angles to the first and top layers, and offset the top layer from the bottom layer). Use Felt Capping role for the edges / awkward bits.

Still not worked out how to get my drips to stay folded under yet!

It's really expensive stuff
I replaced my shed roof with see through plastic sheeting which makes the shed a lot friendlier for working in
My shed is out of site so I don't care what it looks like
If you do go down the felt route I'd consider doing several layers at the same time so you can just peel one off when it fails
Local gumtree and eBay always seem to have it if you are not in a desperate rush

Just done my shed after moving it with the Wickes extra durable shed felt. Comparing the standard and extra durable in the shop they're miles apart, the standard stuff is very thin and tears easily whereas the extra durable was thicker and wouldn't tear. Used a brush on felt adhesive on the overlaps as well.
Can only see if it stands the test of time. The stuff I took off tore very easily and was pretty knackered, only had the shed ~5 years but was in the sunniest bit of the garden so may not have helped, it's now in the shadiest bit!
I'll report back in a few years
