Nonogran, sorry to be the bearer of bad tidings but the leaves are the least of your problems. The tree roots are massive, they have to be to support the exterior structure. Tree roots that grow towards your house will eventually lift the footings of your property, that in turn will cause extensive damage like a wall cracking. The way to stop that is for the tree to be root pruned.
How I know that is because I lived in a tree lined street back when I lived in London, thankfully the trees came under the council's ownership, one call to them and they sent a parks department specialist. He it was who explained what tree roots can do to a house.
As for resolving the leaf issue, my neighbour didn't like the fern that overhung into her garden, she asked if I could have it pruned back, she even offered a payment towards the cost. I declined her offer and had the tree pruned back. She was most grateful and now I live in peace with my neighbour.
