what to use at barge board corners

AlanB1976 · 4 Oct 2015

Hi all

I'm re-doing a flat mono-pitch roof and am a bit confused on what to use at the barge board corners. 3 of the sides will have the barge boards as in the following link.
http://www.steelroofsheets.co.uk/products/polyester-paint-barge-board-200mm-x-200mm/
Everything I've found deals with boards that aren't flush like these.
Can anyone point me in the right direction?

Thanks
Alan

If you post pics it would help.

Unfortunately I haven't yet installed them so can't take any pics. I've drawn the below image to hopefully explain what I mean. Where the 2 overlap, there will be that slit down the wall where there is no protection and water could get in. I could silicon them but I thought that this would be a common thing and there would be some type of solution already.

Also, I'm not actually sure on which should overlap (sides or ridge). Is there a preferred method?

Thanks for any help.

so this is a flat roof? and those pieces of timber you have drawn arrows on are fascias?
not sure what those angle-iron shaped pieces of trim are but can you get a 'corner piece' ?

Isn't a "corner piece" just a short length of the regular stuff in your link/sketch but trimmed down to size? It's got a corner already!
