They make "stick on" things that look like the saddles you use with zip 
ties to hold cables on a chassis, but made of metal or UV resistant 
plastic with a bit of curvature.

To attach those, they have double stick foam (3M VHB - Very High Bond, I 
think) that is very weather resistant (used for holding windows in on 
skyscrapers, for instance).  I have a 15-20 year old roll of VHB and 
lots of things stuck up outside for more than 5 years that are still 
stuck (in Southern California, so we don't get freezing very often, but 
it does get hot.. surface temp in the sun is probably well over 60C)

There are things which can be epoxied on, as well.  Epoxy will never 
come off, if the surface is properly prepared.
