What pruning actually buys you
Every winter, ice and wet snow find the deadwood, the cracked crotches, and the limbs that grew out over the shingles. Pruning removes them on your schedule instead of the storm's. A maple with a cleaned crown carries ice it would otherwise shed onto the porch; a pine backed off the roofline stops sanding your shingles and filling the gutters; a young tree shaped early grows into strength instead of into trouble.
Done right vs. done fast
Proper cuts happen at the branch collar, sized so the tree can close them. What you don't want is topping — hacking the crown flat — which trades one year of shorter for a lifetime of weakly attached regrowth that fails in exactly the storms you were worried about. Any pro this service connects you with will talk you out of topping, and that refusal is a mark of competence, not stubbornness.
When to do it
Dead, broken, or dangerous limbs: whenever you find them — that work doesn't wait for a season. Structural pruning is often easiest in the dormant months when the branching shows. One local note: sugar maples run sap hard in late winter and early spring and will bleed from fresh cuts then; it looks dramatic and is mostly harmless, but if it bothers you, prune maples after the leaves are out. Whatever the species, ahead of winter beats after it.
