Sounds like some kind of mold or fungus. I get some black stuff on the north
and east side of my house but none on the south and west. Guess which sides get
the sun.

Likely suspect, as you say, is mold/mildew on the shady sides of house. May also
be sap or pollen from trees. Sap is usually a bit sticky, though. Try cleaning
it off with bleach added to your washing solution - if too high up you can use a
hose end garden sprayer. Just be careful of what you get the bleach on - will
cause rusting of metals or rotting of fiber if too strong.
You cannot prevent them from hanging around or pooping, but you can use a
garden hose to wash them off.
Hope this helps.

If they're distinct spots not much bigger than the period of a
typewriter, they're probably flyspots. Larger spots with fuzzy
boundaries would likely be mildew.

Sorry, it's fly poop ("flyspots"). The stuff is tar-like and probably
will slightly dissolve plastic under the right circumstances, hence the
pits.
Get rid of what's attracting the flies.
