Beginning late November until the end of February is the time to prune trees. While not always necessary, the main reason your beauties may need a trim is for safety. Long branches that have previously had lateral branches removed repeatedly may be weak. They should be removed or at least shortened. Narrow branch v-shaped junctions may be in danger of breaking.
Also an issue, is disease. Naturally we can see the dead and dying branches, but when pruning it is important to not trim limbs with leaves. The leaves are food production against disease.
If your trees are looking a little rough around the edges, they may need to be trimmed for appearances.
Oak trees are frequently painted after being pruned to avoid oak wilt. You should still be able to see some sky through the canopy. A good rule to remember is to never remove more than 25% of the canopy in a year.
