I have a small (18' x 24') mountian cabin with an alum. Metal roof.
This has begun to leak, and I'm destined, next week , to go and
re-pound the nails, and replace the loose ones with roofing
screews/washers.

What I am curious about is where in the roofing should the nails be
located??

The roofing has roughly the following profile

-----------/\---/\------------/\---/\------

with a set of 'peaks' about 2 " from the edge. It would seem to make
sence to nail in the valley between peaks, but I have know clue, if
that is correct...

Any Ideas????

Thanks for your time...

I thought the "peak" was supposed to be installed on top of the "peak" on
the next panel, thus preventing water from working under the seam where the
panels meet. Looks like your roof was installed wrong, to me. Then when
nails or screws are used on top of the overlapped peaks, they are above the
flow of water coming down the roof and less likely to leak.
