I am going to felt over OSB on a garage roof. The garage is 5.2m long which means I can't get two lengths out of a 10m roll. The shortest roll I can find seems to be 8m. Am I basically stuck with wasting somewhere between 12m and 20m of felt (4 lengths required)?

Maybe if you ask the manufacturers very nicely they will make roll lengths in 1m intervals from 1m up to 20m? Thus keeping everyone happy?
What exactly are you proposing to do? ie are you taping the joints of the osb, how many felt layers and of what type are you laying etc. It's bad practice to lay a lap of layer 2 on top of a lap of layer 1 etc, you need to stagger the laps. So although your first layer might be 4 strips, your second layer should be a half strip, then 3 strips, then another half strip (or a third, then 3 full, then a two-thirds, depending on layers).
Would laying at least one layer across the way solve your problem?

just dry laying one layer of good quality felt. Four strips running the full length of the garage. The upper strips will overlap by about 400mm at the ridge
I guessed I probably would have some waste..Still, if you are doing these things yourself, you trade off this against the cost of getting somone in.
