An updated tower

When the work for painting the metal on the roof started last year, casually, some "older" metal suffered of the powerful washing that was performed. Well, in theory that is just a mere coincidence, but we are rather convinced that the reason why some serious holes appeared was surely not just because it was time...

Nevertheless, since our idea was to have metal sheets in titan (rheinzink), we agreed with the plater that we would have to wait this spring to have the work done, once because of course they were occupied but also because the rheinzink can be worked only when the temperature is over 10 degrees.

The metal was patched by the roof painter for surviving the winter. 

We booked so that they'd come in June and so they did. They remove most of the old metal and while I confirmed that they were going to use rheinzink, they stated that they were going to use, to my total surprise, galvanized metal.
Galvanized metal is not to be recommended to be used anymore, the roof experts say, as the passivation layer make the surface too perfect for being painted.
But this is nothing strange with the contractors. You agree on one thing and it turned out to be what they want.

"Cultural" metal sheets

Before having something we really don't want, I managed to suggest to use "cultural" metal sheets, which is metal sheet that has a prepainted layer at production. 

Luckily, not only they agreed with this and they had the material in their shed, so that is what it should be.

Eventually, everything was done and the work concluded.
So, now the roof should last with this patch even longer (I wonder why the first roof company didn't fix it).
