If the wood below the EPDM membrane is wavy or bubbly, the wood deck is probably rotting and needs to be replaced. Just working on the existing membrane to stop leaks will not stop deterioration of deck below. I would recommend an inspection of the wood deck before any repairs are attempted. I have repacked an entire roof membrane and deck due to rotting wood on one trailer, and another had to rebuild front corner due to rotting wood deck.
