The closest Maryland address to the boundary, where the parcel check decides.
Upper Marlboro measures 13.7 NM from the DCA VOR/DME — inside the Washington DC Special Flight Rules Area, outside the Flight Restricted Zone, and closer to that boundary than any other Maryland address we serve. At this distance the town name settles nothing: your parcel's position is what decides the flight. We verify it before we promise a date, then fly radiometric thermal and high-resolution visual capture across 100% of the surveyed surface.

Upper Marlboro sits inside the DC SFRA at 13.7 NM from the DCA VOR/DME, outside the DC FRZ but the closest of our Maryland localities to that boundary — so at this distance the parcel check is what decides, not the town. We pull your parcel's position and its cell at the centroid and corners before any date is offered. Inside the SFRA the standing UAS security NOTAM is VMC-only and bars night, so flights are scheduled in daylight and twilight windows. Controlled airspace also requires prior FAA authorization, which is part of every site's setup rather than an afterthought. The DC Flight Restricted Zone is out of scope for our aerial work, and we say so at intake.
HOW THIS IS READ → THE AIRSPACE GUIDE- 13.7NM
- Great-circle distance from the DCA VOR/DME — inside the 30 NM Special Flight Rules Area, closest of the Maryland set to the FRZ boundary
- 100%
- Coverage per single mission — every section surveyed, no personnel on the membrane
- Centroid
- Altitude method — the cell pulled at your parcel's centroid and corners, never a single town ceiling
- 48HR
- Findings report targeted within 48 hours of capture — geolocated and severity-ranked
What we inspect in Upper Marlboro.
Government and institutional buildings
The county seat's civic and court buildings — long-span assemblies over public interiors, where a slow leak surfaces as a closed office or a damaged record before it surfaces as a repair line. Thermal and visual capture read every roof plane in a single pass.
Agricultural and large-lot property
Barns, outbuildings, and long-roof houses on acreage out past the town limits. Assemblies at this scale are faster to survey from the air than from a ladder, and the record stays consistent property to property.
Equestrian estates
Indoor arenas, stabling, and hay storage across the county's horse properties. Tall, wide, and often uninsulated — roof condition and any moisture path read clearly in thermal, from outside the building.
Commercial and office roofs
Low-slope assemblies across the town's commercial blocks. Moisture trapped under intact membrane is invisible from the ground and obvious in thermal — located by section, before it becomes a tear-out.
Industrial and flex roofs
Metal and membrane roofs over light-industrial and warehouse buildings. Fastener stress, seam failures, and wet insulation each read differently in thermal, and the report says which is which.

Upper Marlboro, answered.
Upper Marlboro is inside the DC SFRA. Can you fly here?
Yes — 13.7 NM from the DCA VOR/DME puts Upper Marlboro inside the 30-mile Special Flight Rules Area, and it is a servable locality for us. SFRA operations run under FAA authorization with NOTAM discipline, which is part of every site's setup rather than an afterthought. We verify the specific parcel before we commit to a date.
Upper Marlboro is your Maryland locality closest to the FRZ. Does that change anything?
It changes the answer from town-level to parcel-level, which is the point. Upper Marlboro lies outside the DC Flight Restricted Zone, but at this distance two addresses a few miles apart can land on opposite sides of a boundary, so every parcel gets its own position check at the centroid and corners. Inside the DC Flight Restricted Zone, aerial work is out of scope for us, and we say that at intake rather than halfway through a schedule.
What altitude will you fly over our property?
Whatever your parcel's cell allows, or Part 107's 400-foot limit, whichever is lower. No cell value was returned at the Upper Marlboro area, so there is no published grid ceiling to quote — altitude resolves through the authorization path. We work the parcel at its centroid and corners instead of quoting the town a single number.
Can you fly at night over the property?
Inside the SFRA, no — the standing UAS security NOTAM limits operations to clear-weather daylight and twilight. Thermal contrast does peak in the hours after sunset, so on parcels verified outside the SFRA we schedule night capture; for Upper Marlboro parcels we plan around the twilight and dry-day windows, which still produce strong ΔT separation on a wet roof.
We manage a large-lot property with barns and an arena. Is that a fit?
Yes. Large, tall, and often uninsulated assemblies are among the fastest things to survey from the air, and nobody has to walk a stable roof or set a ladder against an arena wall. Coverage per single mission — every section surveyed, with findings written as scope for your own contractor to price.
Who acts on what you find, and do you publish it?
Your own contractors and maintenance team. Jinki inspects only and performs no remediation, so the report carries no conflict of interest, and every finding arrives with the image pair and measurement attached. You get a mutual NDA by default, and we do not publish client sites, tenant names, or findings.
