Mike,

Don't pound the nails in. Pull each nail out,one by one, replacing
it with a screw/rubber washer which Home Depot sells. Make sure to
use a diameter large enough so that the screw threads will engage...

I've seen panels installed with fasteners in valleys, and with
fasteners on peaks. I prefer the peaks, myself, since the rain runs
into the valleys in torrents and floods the head of the fastener. The
rubber washers seal it, but, hey, nothings perfect forever. On the
peaks, the water never builds up.... However, in several types, the
manufacturers reccomment fastening to the valleys, since one can
get a tighter seal, since the peaks flex over time. That's why they
ALWAYS recommend the fasteners - screw type-- to get a nice
tight compression to the washer....

I'm afraid you have a continuing problem with your roof because of
the initial installation..... if you stay on top of it, you will not
have to
buy as many buckets to use inside.... good luck..

PS Don't drink the beer until AFTER you come down off the roof.....

You need to pull out and replace the nails that come loose. New
neopreme seals will extend the life greatly. Adding a longer nail
than you pull out will give you greater holding power. Use screws if
you like, especially in those areas where there are lots of nails
working loose. It indicates the wind plus expansion and contraction
is loosening your nails.




And stay out of the valleys. That's for the water.
