I have roof moss and Roundup just doesn't seem right, maybe I'll

It's very easy to get rid of roof moss, remove whatever is shading the
roof, then spray with bathroom tile mildew remover... if you do not
remove whatever is shading the area the moss will come right back...
I'd not wait too long before rectifying your problem either, moss
indicates a moisture problem, your roof will soon be leaking as the
roofing and sheathing beneath will be ruined, and home owner insurance
will not cover your neglect.

Well, the shade can't be cured. Neighbors huge trees.
I know they won't remove them. It's pretty shady anyway, as the house
faces directly south and theses are in the back.

You can legally remove whatever parts of those trees cross your
property line, from hell to heaven, just at your expense.. might pay
to discuss this with your neihgbor and come up with a plan whereas his
trees aren't pruned so heavily that they look unsightly and then share
the cost. If that doesn't stop the moss from growing it won't be too
long you'll need your roof repaired so I suggest before your roof
leaks and does horrendous damage inside your house you have that
section replaced with a different roofing materal, possibly a roofer
will suggest metal roofing for that section.

I find it odd that you think a fungicide will work on moss.
Not really the same thing.

Not the same but it works... moss grows on my black top driveway in
front of the garage door because that faces north and never sees sun.
So each spring I spray that area with tile grout cleaner and apply
elbow grease with a stiff brushed scrubber... actually what I first
used is vinyl siding cleaner compound that contains an anti mildew
agent, I discovered it works on moss when I power washd my house and
the compound ran down my driveway, only I can't use a power washer on
blacktop or it will lift out the stones and leave holes, with heavy
use a power washer even on a low setting will destroy blacktop.
Whatever the chemical(s) in that power washer cleaner it kills moss,
then it can take a month or two for the dead moss to decay and wash
away. But naturally during the next summer it grows back, and I can't
prune my garage. The moss won't harm my driveway but it looks
unsightly.

Thanks for the pointers on the urgency. I know I have to do something.

Yes, I'd not put it off.

Good idea to seal your driveway. There is enough free space in the
composite to allow moisture intrusion and repeated freezing and thawing
will degrade it faster.
