Hello!
I have a question about our house that was completed in 2010.
The lower batten was completely unpainted and with no sheets on it, and after a while, the house builder thought it might be a good idea to cover the lower batten with a sheet metal, presumably to both create a better appearance and protect against weather and wind.
It was intended to have an air gap down towards the eave plate of between 3-5mm which I think sounds a bit small, but then it ended up being between 0-3mm as you can see in the picture.
Shouldn't the air gap between the batten and the eave plate be 10-15mm or is it okay with just around 4mm?

Ideally, it should also allow water to flow down.
Almost right, it is from the top: roof tile, red metal on the battens, gray eaves flashing (the upper part is shadowy, hence it could be mistaken for roofing felt) and lastly gutter, I suppose the roofing felt doesn't extend so far over the eaves flashing.Larsa said:
If you are going by the book (AMA), the foot flashing should be attached to the sheathing and then the felt should be laid over the flashing and fastened with the adhesive edge (depending on the type of felt you have).
Most home builders and house constructors usually screw the foot flashing into the battens instead because they think it looks nicer.
If the foot flashing is placed under the felt, some people attach an extra foot flashing on the battens to avoid seeing the battens, as in this case.
Regarding the gap between the sheets, the important thing, as mentioned, is that the water that comes under the tiles can flow between. It’s not a large amount of water, but there will be some condensation water.
