Flashing back edge of log store slate roof.

[John Brown]

Just moved our ancient log store, and replaced the rotting featheredge roof with slate. Not sure how to finish the high side back edge. It's free standing, so I was thinking that some sort of unequal angle thin aluminium would do, might look neater than lead(possibly cheaper too), but don't know whether such stuff exists, or what search term to use. I'm not overly bothered about it being totally weatherproof, just want to cover the joins in the top course of slates.
Does this make sense?

Is this what you want

I'm assuming you mean something like this, but the slate is on a freestanding log store. If your flashing does not have a connection to the wall with some effort to seal between wall and flashing then I wouldn't bother. Without this seal any moisture/rain on the wall will run behind the flashing as the brick roughness will create sufficient gap, if this happens then the flashing is a waste of time/money.

Regards the flashing material I have had pretty good success in making simple items from 1mm aluminum sheet, you can trap it between two lenghts of timber and make simple profiles bending it along the trap point. I don't know how you would affix it to the wall, a bead of sealant may last some period but not for that long.

Maybe. Was hoping for something a bit cheaper...

I'm not trying to seal or fix it to the wall(it's Cotswold mudstone, so fat chance..), just want to cover the "vertical" seams and the nails of the top course. If I can't find a lead offcut(only need 1.9m) at a reasonable price I might just use flashband.

P.S. Maybe "flashing" is the wrong term.

I ve used lengths of “rectangular” upvc guttering ripped on the table saw to create such things.

I know it’s not what you are thinking of, but jfyi CT1 is brilliant stuff I "glued" slates on to form s roof on a notice board once, the peak was just black CT1 formed to a point and spread about an inch onto the slates. Lasted a few years up to now.
I was thinking you bond canvas or roofing felt to the slates with it?

From your description I think that you have a simple mono pitch structure and it's a mono pitch ridge tile that would normally be used. Expensive for a log store at £70 a pop for 'slate' type.
As suggested, a short length of square, black downspout ripped to provide an 'L' profile and then heat it with a hot air gun and reduce the angle to suit your pitch. Stick it on with Tech7. It works - I've done it for something similar.

Or a strip of lead and form a raised ridge around a brush shaft.

Thanks everyone. I'll keep looking for a lead offcut, and think about other options in the meantime. There's no hurry, as we probably won't be using logs for a few months.
