After the main tower's roof was done, the team started the north flank.

It was initially thought that the roof structure could be saved and simply repaired. Further examination showed that this was not the case. It appeared that rain had been damaging the beams for over 40 years since the previous owner had simply nailed some paneling to hide areas where rain was coming in.

But it also became evident that the floor of the attic was also damaged beyond salvation, again because of the rain, and that it was necessary to replace the floor (ceiling of the master bedroom down below)

So, the roof tiles were carefully removed, the beam structure was removed, and the attic floor was removed. Scary!

The workers soon discovered that the chimneys were on the verge of collapsing and had to be rebuilt. This was done before the roof structure was put in place. First the east chimney, then the main chimney

After that, while easy access was available, all the conduits and piping for the east tower were installed. A new attic floor was installed and new roof structure was built and installed

As you can see from the photo below, this structure is constructed without any bolt screw or nail. It is all done with mortise and wood pins, like it was done 500 years ago.

Some of the roof beams could be salvaged and were used in the new roof. All new timber, originally from sawn oak,  was re-finished by handcrane to give an authentic look.

Then, like in the main tower, a layer of plywood was installed, followed by reflective insulation. Two attic windows were constructed. A first layer of lauze stones was placed on the wall to become the basis of the roof tiles and, finally, the ancient clay roof tiles were installed.
