Hi everyone, this is my first post here. I have a question to you seasoned roofers.

My wife and I bought a summer home in 2011 that was built in 1977. We renovated it but left the roof untouched, it seemed to be in a good shape back then.

The house has a gabled roof, interlocking tiles are supported by diagonal battens. The tiles are tied to the battens to prevent slipping. No underlay.

We had no major issues until now. One of the diagonal battens near the chimney snapped. It pulls one of the tiles down as it sags.

Questions:

Should this be fixed ASAP? Can a strong winter wind lift the tile if it's like this? That would create a hole in the roof and increase the risk that other tiles move as well.

Is this fixable by sistering a new batten to the old one?…
