Our house has a tile hung dormer which faces west, into the prevailing wind. When winds are high, the vertical tiles all rattle - they are all nailed but obvioulsy a little looser than when priginally fixed. As these rattling tiles allegedly keep she who must be obeyed awake, would it be an acceptable practice to bond them together with, for example, a blob of Gripfill, No-Nails or similar?
I would also use silicone and not Gripfill. If a tile ever does break it will be much easier to cut away the silicone blob than to try and cut through hardened Gripfill.
