Short answer: Once a month, watch and listen to your door, look over the springs, cables and rollers without touching them, and test the safety sensors and auto-reverse. A few times a year, lubricate hinges and rollers, wipe the tracks, check the bottom seal and tighten loose hinge screws. Once a year, have a professional inspect the springs and cables, balance the door and check the opener settings.

A garage door is the biggest moving thing in most homes, and it gets used every day without much thought. Most breakdowns don't come out of nowhere. They build slowly: a roller that dries out, a bolt that works loose, a cable that starts to fray. A simple routine catches those things while they are still small.
This checklist is split into three parts. The monthly checks take a few minutes. The seasonal list takes maybe half an hour. The yearly work involves springs and cables, and that part belongs to a professional.
Springs, lift cables and the bottom brackets where the cables attach are under heavy tension. They hold the weight of the door. Don't loosen, adjust or pry on any of them. Everything on this list is either looking, listening, cleaning, lubricating or tightening simple hinge and track hardware.
Unplug the opener before you work near the door or the opener rail, and keep kids and pets out of the garage while you do it.
Open and close the door once while you stand inside the garage and pay attention. You are looking for anything that changed since last month.

Doing this at the change of seasons is an easy way to remember it. Cold weather thickens old lubricant and stiffens seals, and summer heat and dust dry things out.
Door balance tells you a lot about spring health. With the door fully closed, pull the manual release so the door is off the opener. Lift the door by hand to about waist height and gently let go, keeping your hands ready.
A balanced door stays about where you left it, or drifts slowly. If it drops quickly, shoots up, or feels very heavy to lift, the springs likely need adjustment. Don't try to fix that yourself. Lower the door, reconnect the opener and have it looked at. If the door feels heavy from the start, or you already see a gap in a spring, skip this test entirely.
Once a year, have a professional go over the parts that carry the load. That usually means inspecting the springs and cables, checking and adjusting door balance, looking over the drums, pulleys and bottom brackets, testing the opener's force and travel settings, and a full safety inspection.
These are the checks that prevent the most disruptive failures, like a snapped spring on a busy morning. If you want to know what a good visit covers, see what a garage door tune-up actually checks.
Some things are worth acting on right away. Stop using the door and have it checked if you hear a loud bang from the garage, see a frayed or loose cable, notice the door hanging crooked, or find that the door won't reverse when it should. Our list of signs your door needs a tune-up covers the quieter warnings too.

A few times a year is a good rhythm for most homes, often at the change of seasons. Use a lubricant made for garage doors on hinges and roller bearings, and keep grease out of the tracks.
Much of it, yes. Watching, listening, cleaning, lubricating and tightening hinge screws are all reasonable homeowner tasks. Springs, cables and bottom brackets are under high tension and should be left to a professional.
Once a year is a sensible baseline. A yearly visit checks springs, cables, balance and opener settings, which are the parts that are unsafe to adjust yourself.
Regular WD-40 is mainly a cleaner and water displacer, not a long lasting lubricant. A lubricant made for garage doors holds up better on hinges and rollers.
