I am in the process of building my own house. I have now installed the sheet metal roof and will begin with the gable trim. It's a Plannja Regent sheet metal roof.

As you can see in the pictures, I laid the battens all the way against the upper fascia board to get a good attachment of the fascia board to the battens. There is also a counter batten against the upper fascia board.

What I have noticed now, and which might be a little harder to see in the pictures, is that the gable trim is about 2 cm above the profile top of the roof sheet.

In other words, what I'm wondering and am concerned about is how exposed the ends of my battens are? It feels like both snow and water could come in under the gable trim down to the battens. There is an upward slope towards the fascia board under most of the gable trim, but is that enough?

Would you take any measures for this? I don't have any desire to remove any sheets and shorten the battens so that they end under the roof sheet unless it's considered super critical. Does trying to paint the visible end of the battens help at all?

Grateful for any responses!

No worries.

I would recommend screwing the inside of the fitting into the plate where they meet each other, so you won't have any rattling when it gets windy.

You mean to screw the gable fitting down into the roof plate so that it rests against the profile top of the roof plate? (See my finger)

It certainly becomes much tighter.. Apply some paint on the bearing lath and screw down the gable fitting, maybe that will work well then?

The fact that the part of the gable fitting that sits outside the windboard sticks out a bit doesn't really make much of a difference, does it..

Yes, so I thought, "you usually" place the fascia board level with the highest point of the sheet metal or possibly a few millimeters higher to avoid all that.

It's not a necessity or requirement, and it's not guaranteed that you'll get disturbing noise, so you have to decide on-site what will be best based on the conditions you have now. Painting the battens is absolutely not necessary; just let it be as it is.
