Spacing roof sheathing

| Posted in Building Code Questions on
My framers used APA-stamped roof sheathing stamped “Sized for Spacing” on it (photo attached). However, they installed the sheathing butted up tight with no spacing. Will this cause problems down the road or void any warranties? If it’s not done right, what would be a good solution?
The wall sheathing is also stamped “Sized for Spacing” but there are no (intentional) spaces between sheets there either.
Location is Anchorage, Alaska. My building site is very exposed on the crest of a ridge in the foothills. That means lots of snow, wind-driven rain, big temperature shifts and differentials between inside and outside temps, etc.

Paxson,
That's kind of strange. If the framing is on 16" or 24" centres, and you don't space the sheets, you soon have your ends running off their supports. I wonder how they managed to avoid it?
That aside, I've seen an awful lot of tight plywood sheets and never noticed an issue. OSB is more problematic.
Thanks for the reply. I'm attaching a photo looking up at the roof. There are lots of visible side seams (though no panel end seams as far as I can tell).
I wouldn't worry about it.
