Last spring a homeowner on a quiet Willow Glen street asked a question I hear about once a month: he had bought a $500 drone to look at his roof after a windstorm, flew it for six minutes over his 1956 ranch, and a neighbor told him he had broken federal law. Had he? The honest answer depends on why he flew, where he flew, and whether he had done a few things beforehand — and San Jose is one of the trickier places in the country to get all three right. I have carried a Part 107 certificate since 2017 because I fly roofs for a living. Here is how I explain the line.
The question is purpose, not the size of the drone
The FAA sorts small-drone flights by purpose. If you fly purely for enjoyment, you can operate under the recreational rules, which require passing a short free online safety test and following common-sense limits. The moment a flight has a purpose beyond recreation, it falls under Part 107, and the person at the controls needs a remote pilot certificate.
The trap is that commercial does not mean paid. Flying to document your roof so you can send the footage to an insurer or a roofer for a quote is generally treated as non-recreational. A home inspector flying a client’s roof is plainly commercial. A homeowner flying for fun who happens to notice a missing shingle is in a gray zone I would not want to argue about after a complaint. My rule: if the footage will be used to make a decision about money, assume Part 107 applies. The current rules are on the FAA website, which is the place to confirm, because the details change.
San Jose airspace is the harder problem
Even a purely recreational flight over your own backyard has a second gate here. San Jose Mineta International Airport sits in the middle of town, and its controlled airspace covers most residential neighborhoods: Willow Glen, Rose Garden, Japantown, parts of Naglee Park. Inside that airspace, any drone flight needs authorization before takeoff.
In practice that means LAANC — the automated approval system in major flight apps. Drop a pin, request an altitude, and for most of Willow Glen you get an answer in under a minute with a ceiling between 0 and 200 feet depending on the grid square. Some squares near the approach path show a zero ceiling, requiring a manual request that can take weeks. Check the specific address every time; the grid does not follow neighborhood lines. The homeowner who asked me the question had flown without authorization in a 100-foot square at roughly 60 feet. His altitude was fine. His paperwork was not.
What a certificate actually costs and what it buys
A Part 107 certificate requires passing a knowledge test at an approved center. The fee is about $175; study materials range from free to $300. Most people who study for two or three weeks pass. Recurrent training is free every 24 months. There is no practical flight test.
What the certificate buys beyond legality is a pilot who has thought through airspace charts, weather minimums, and control-link failures. For a roof survey that is not trivial. I have watched a hobbyist fly a drone into a Douglas fir because they were looking at the screen instead of the tree. Hiring a certificated pilot in Santa Clara County typically runs $150 to $350 for a flight with edited footage — less than most drones’ deductibles.
What a licensed flight looks like on a roof
When I fly a roof for a client, paperwork comes before footage: LAANC authorization, a TFR check, a battery log, and a note of who was present. The flight follows a pattern refined over a few hundred roofs — context orbit, straight-down grid, oblique passes at 12 to 15 feet above the surface, which is where problems show up. I documented one of those flights in detail in the notes on a drone roof survey before a reroof; the method is the same on a San Jose ranch as on a cedar roof in Oregon.
California has stronger privacy protections than most states, and a drone at 40 feet over a fence line sees into every neighbor’s yard. I keep the camera on the roof I am there to record, do not fly over adjacent lots, and tell the neighbors before I launch. On a 6,000-square-foot Willow Glen lot that conversation takes two minutes and has prevented more than one complaint.
Frequently asked questions
Do I need a Part 107 license to fly a drone over my own house? Not if the flight is purely recreational, but you still need to pass the free recreational safety test, register the drone if it weighs over 0.55 pounds, and get airspace authorization if you are inside San Jose’s controlled airspace, which covers most central neighborhoods. If the footage is for an insurance claim or a contractor quote, assume Part 107 applies.
How long does LAANC authorization take in San Jose? Automatic approvals in most grid squares come back in under a minute through a flight app. Squares near the SJC approach path with a zero-foot ceiling require a manual request that typically takes several weeks and is often denied.
What does it cost to hire a Part 107 pilot for a roof survey? In Santa Clara County a residential roof flight with edited clips and stills generally runs $150 to $350. Some home inspectors include it in a full inspection for an additional $75 to $150.
