I’ve got access–almost next door– to a lot of used 1 x 8’s (nominal), that are shiplapped. They would end up being about the same price as (thinner) sheet goods. Any reason NOT to use them on my shop roof or walls?
If not, do they need 3 nails in each stud, as they appear to have had, or just 2?
And, should they be installed slightly ‘loose’, for expansion?
Thanks.

the majority of my work is roofing on older houses with 1x8 decks.
3 8d nails at every rafter or stud location.
the stuff we encounter is almost always straight edged----but occasionally shiplapped on small flat roofs.
If the stuff is really dry and solid---why not use it?
Disclaimer******---some shingle manufacturers do not want to warranty installations over 1x8---preferring 1x6 as the maximum. I have seen instructions where shingle manufactures actually want you to cut any 1x8's on existing decks in half----presuming expansion and contraction issues.
I have used miles of 1x8---never ripped in in half----never had a problem from it.
1x8---nailed on a roof deck are gonna dry out FAST---but I would use some common sense regaurding spacing. on 1x8 shiplap I probably wouldn't use the 8d nail spacing trick------but I wouldn't try to pull the decking perfectly tight either----I would assume at least a whisper of movement.

Thanks! Sometimes common sense makes sense. <g>
