the garage roof is showing it's age. Presently it's mineral felt over felt underlay over boarding set on pitch. there are stones on top of the felt also. The boarding is not in the best of nick but not beyond it's life - well from the underside there is no signs of water damage.
The span is 22ft with a 6in fall.
What I'm considering is to sweep the loose stones off/up and then lay polyester coated roofing sheets over the existing felt.
What I'm concerned about is the fall sufficent for such roofing sheets; especially if I'm unable to obtain sheets of the right lenght.
Thoughts.
