Tree pitch? Do you mean sap? It can certainly, in the right conditions, damage the finish but I haven't seen it eat through.

Is algae a problem on metal shake shingles

Algae can grow on anything if the conditions are favorable for it.

In the comparison, algae will be much, much less likely to grow on a non-porous substrate like metal as compared to something like shingles or wood shakes.
