Decking fascia boards

[LoganF]

Is there any problem with installing fascias so the top is flush with the top of the deck boards? Was thinking drainage may be an issue but the opposite side won’t have a fascia as it’s unseen so water can run off that side?

Heard from a few folk that it’s a neater way of doing it to hide the deck board ends.

Thanks in advance!

I think it's neater to have the deck oversailing the sides but each to their own. You don't seem to have left any gap between the 'fascia boards' as you describe them.

Put a bit of a slope on so water runs off. The grooves need to go the way the water runs so you can sweep them clean, brushing along the grooves.

You do not want water and dirt running down the house wall.

If you're going to do that it'll look much nicer if you mitre the corners.

Also, IMHO you've put your boards upside down, but I expect you did that on purpose out of personal preference.

Yes I’ll take them off and mitre - realised that when I put them on.

And I didn’t realise there was a top and bottom to the boards - what do you mean?!

Thanks. There’s a 5mm gap but not where they butt together - will be mitring that corner.

Most decking boards are ribbed on one side and smooth (or smoother) on the other. Apparently the ribs are supposed to be down, to create airflow where board meets joist. They also look better that way, but that's a matter of opinion of course.
