Roof Shingles- Algae, Hail Damage or something else?

Hi Gents-
Anyone see this before? Algae? Hail Damage?
Doesn’t look like hail damage because so much, so small, and granules look in tact.

Appreciate your input.


What is around or above the roof?

Can you post pictures from further back with an overall view?

Dud you touch them? Do they feel like blisters or divots or surface stains?

What kind of large trees are near/overhanging the home?

No direct trees around roof/house currently.
Roof is 20yrs old.
I do see algae on some of the trim.
I just never saw in this pattern before.





Without more info, such as what Dom asked above, etc., I would guess algae.

Need I say more?


.

It is not raised at all like moss or lichens…
On front and back of home…

If it is algae on the trim, most likely it is algae on the shingles.
