Hello knowledgeable shed types.
The roofing has started to deteriorate on my 4X6 single apex sloping
shed roof.
It has to be 20 + years old. It looks to be covered with a kind of
plastic with little 1/2 inch square reinforcement 'string' integral to
its make up. I haven't seen any of this on a roll so. Do I just get the
heavy tar and gravel type roofing felt? The stuff that normally goes on
top of roofing laths and under tiles/slates.
Any advice thankfully received. Cheers

The "Rolls Royce" answer is three layers of roofing felt, all fastened
down and together with hot poured bitumen.

Then again, it *is* a shed, so a single layer of cheap mineral covered
felt, overlapped at the joints and nailed down is the normal answer. or
whatever other waterproof stuff you can find laying round. You might
want to make sure that the wood in the roof isn't rotten.
