Hello To all,
Have small shop building with corrugated metal roofing.
Have small house with corrugated cement roofing.
Both roofs leak during moderate and heavy rain but not in light.
They seem to be leaking at the fasteners as the leaks are in nice neat rows.
Any thoughts on how to seal the fasteners.
Thanks,
Hank.

If you are confident that the roofing is otherwise sound and it's really the fasteners, you can tighten them or replace them (if I was going up on that roof and spending the time to tighten them all, I'd just replace them all).
Here are some sources for fastening metal to wood (I assume that's what you have) with the gasket, and for roof tile.

Best of luck.
Seeking perfection in an imperfect world is a fool's errand. Making something look perfect is a whole 'nother story . . . .
You're right; once you are up there you might as well do all of them.
The salt air here is tough on metal; I'm sure the fasteners will be corroded.
The roof material is sound as are the purlins (3x8 cedar).
Thanks,
Hank.
