How to fix a shed roof is a topic that can certainly range in extremes, from simply tacking back down some loose felt, to discovering the ply or building boards (roof sheets) used to make up the structure of the roof are totally rotten, and so complete replacement becomes necessary.. Shed roof repair consists of removing the old shingles and rotted sheathing if necessary. many times when shingles start to deteriorate water seeps through the shingles and onto the plywood sheathing therefore rotting the sheathing as well..
I had a similar problem to you, but as big-all said "check all timbers especially near the ground before you buy the ply in case other parts are rotten and make repair uneconomic" but in my case it was the top, where the roof had been leaking it rotted away the back side wall (where it met the roof) i had a new shed built in the end.. 10 step shed health check 1. check the roof felt. look for holes or splits in the roof felt and check your roof felt is still waterproof. repair if: you have spotted the hole or split quickly and the roof timbers are not damaged. replace your shed if: the roof timbers are already rotten. 2. look for leaks. Roof decking, which is nailed to the roof's trusses, holds roofing materials, including felt paper and shingles and also serves to stiffen your home's structure and protect it from wind. replacing the rotten roof boards helps protect the integrity of your home and prevents damage from leaks..
