Well, I saw 12 degrees and thought he was referencing temp. We measure rise and run as 3/12. Oh well, sorry about the confusion, 12 degrees on a roof is not the same as 12 degrees C.

Make sure that the screws are in straight and not crooked or run at an angle. Also make sure any flashings are in tack. If its free standing does the metal extend up past the top edge if so it should have a top flashing that extends down the fascia and down the roof, imagine and inverted L.

Oldog: don't they stap the roof before applying metal?

All the metal suppliers we have available locally want the metal panels applied to solid decking with a water proofing membrane underlayment. If you place the panels on battens you will compromise the seams when they are walked on. Battens will also cause a damming effect should moisture get behind the panels. An air space will also develop condensation behind the panel.
