Can I ask for some advice for a friend of mine please with the above problem?
He owns a top floor flat in a block of four. His flat runs front to back on the right hand side of the block, with the right hand side ground floor flat below his and an up and down stairs left hand pair mirroring this configuration.
The flank tiles along the edge of the gable end roof have become insecure and the concrete fillet is missing in some places has fallen to the path below. The loft space is open to rain snow and birds and now has damp problems. It will get worse if it is not made good.
What can he do to force the leaseholders to contribute towards the cost of repairs, in the region of £2k?
