I want to re-roof and hence "water-proof" my garage. Currently it's more of a lean-to with an opening at the rear of the roof to provide access to a downpipe that takes rainwater into a drain inside the garage. In order to avoid having to move the drain (and hence reduce cost) I'm thinking of rerouting all guttering from the main roof into an alternative drain at the rear of the property and persuading my neighbour to let me drain rainwater from the garage roof into his gutter that's literally cm's away.
Before I enter into that conversation can you think of any good reason he may have to say no? (forewarned is forearmed afterall).
