Siberian larch as roofing material?

[owas]

I'm knocking up a timber porch with a lean to roof, open porch not closed.
Nothing fancy but I don't want it looking modern/upvc ect

Was going to do cedar shingles but that ends up quite expensive.

Some nice looking siberian larch boards popped up on marketplace so I grabbed them,
They're feather edge 25mm>13mm 8 inch wide,

Will larch do the job on a roof? I've got enough here to overlap them as much as I need, what would be best?
Any treatment needed .. I really like the silvery grey it goes.
Do you have to use stainless nails like oak or will galvanised suffice?

feather boarding or doing shingles ?

shingles they are great for but for feather boarding they should be just as good as they are a hard material

Pine tar would be my recommendation

Pine tar would be my recommendation

but hes bought them already

Imho Aspen only. Over time, it will become a noble lead-gray color, it does not prick and is not afraid of repeated wetting, it does not rot. Galvanized nails will leave traces of oxides over time.

Pine tar would be the treatment to make them last longer if used as shingles. Pine shingles here would have a lifespan of 25 years.

give them a coat of 5 star clear wood preserver

I used galv on my cedar shingles, wish I used stainless!!

Yes to stainless nails pre drill to avoid splitting

Went with stainless screws and left them as featheredge.
