Which laps are the gaps in, bottom or side ?. Stitch bolts and plastic
washers are used to fill old fixing holes.

Thanks for the great suggestions, everyone. the gaps are at the overlaps,
at the ends/bottoms of each sheet. I had to repair the roof using some
corrugated asbestos that was slightly different "wavelength" to the
original stuff... or maybe the original stuff had got flattened a bit over
the years. So I have bigger gaps than I would have if the whole job had
been done with identical sheets. Owing to a scarcity of spare sheets to
affect the repair, I have ended up with only 4" overlaps down one strip of
the roof. So the expanding foam will be particularly necessary, for
stopping the wind blowing rain back in, under the overlaps.
