Or add vent pipe penetrations ~ 1.5" OD PVC pipe and put the GPS antenna
on top of the pipe.
Allows for vertical position variations. and the soft rubber gland
allows for changes later.
Had a new roof put on last year and I added 2 each of these plumbing
vent type roof penetrations.
Also added 6 each passive roof vents to keep the heat down,
which could also be used for GPS antenna mounting and cable penetration.
Neither roof vents nor the GPS antennas (~ at ridge line) are visible
from the street.

There are ways to do it w/o drilling holes. Most all houses have vent
stacks for the plumbing, typically 3 or 4 inch cast iron or thick plastic.
You can clamp a couple of feet of pipe onto one of those and run the wire
to under an eve or through a gable end, adding a drip loop of course.
But, if it were my house and I just wanted to discipline my local
standard, I'd try the attic first. Among other things, you can get to the
antenna w/o climbing on the roof!

if
it was sufficient to simply mount my Thunderbolt GPS antenna high in the
attic.
It will work but it will be far from optimal. All you need to do is get a
big drill bit and drill through the roof and put up an iron galvanized
pipe. Put a pipe flange on the end and bolt the GPS antenna to that.
You
will need some metal flashing and roofing tar and then you will have a
first class setup. You run the coax down the pipe. The timing antennas
are pointed on top so snow falls off
