My god son has just moved into a new flat and when it rains heavily, rain water leaks through the wall and exits through a door frame. He went up onto the roof and there seems to be a lot of crumbling stone work around the chimney area where it meets the flat roof.
Is there anything he can do cheaply to fix it until his landlord finally sorts out a permanent solution?
