A historic downtown and an I-270 corridor, read after sunset too.
Frederick measures 37.6 NM from the DCA VOR/DME — outside the Washington DC Special Flight Rules Area, unlike nearly every other address we serve in the region. No SFRA procedures apply at the parcel level, so night capture is on the table wherever a parcel is verified outside the boundary. We confirm the position first, then fly radiometric thermal and high-resolution visual capture across 100% of the surveyed surface.

Frederick sits outside the DC SFRA at 37.6 NM from the DCA VOR/DME, so the standing UAS security NOTAM that governs our work closer to Washington does not reach this city. Outside the SFRA, night operations are lawful Part 107 flights with anti-collision lighting visible for at least three statute miles and a remote pilot current under the applicable training and testing requirement — no waiver required. Night scheduling applies to parcels verified outside the boundary, and every parcel is checked before a date is set.

What we inspect in Frederick.
The historic downtown commercial core
A large historic core where roof ages, pitches, and assembly types change block to block. Capture runs entirely from outside the building, so cornices and steep-slope sections get surveyed without anyone on the roof — and the record is comparable building to building.
Industrial and manufacturing roofs
Metal and membrane roofs over Frederick's manufacturing plants. Fastener stress, seam failures, and trapped moisture each read differently in thermal, and the report says which is which.
Data-center and logistics roofs along I-270
Large low-slope assemblies and long logistics roofs on the I-270 corridor. Wet insulation under intact membrane is invisible from the ground and obvious in thermal — and after sunset, on parcels verified outside the boundary, sub-surface moisture separates most cleanly from dry insulation.
HOA and planned communities
Townhome rows and planned communities across the city and the surrounding county. One pass produces a reserve-study-grade record for boards deciding where next year's roof budget goes.
Agricultural land and outbuildings
Barns, outbuildings, and long-roof houses on working acreage. Assemblies at this scale are faster to survey from the air than from a ladder, and the record stays consistent property to property.

We come back with the parcel's position relative to the SFRA boundary, the authorization picture, and whether night capture applies to it — before anyone talks about scheduling.
Frederick, answered.
Frederick is outside the DC SFRA — what does that change?
Three things. No SFRA procedures apply at the parcel level, night operations are lawful Part 107 flights on parcels verified outside the boundary, and the scheduling picture is wider because the UAS security NOTAM that shapes our work closer to Washington does not reach this city. Your parcel still gets its own check before we set a date.
Can you fly at night in Frederick?
On parcels verified outside the SFRA, yes — night operations are lawful Part 107 flights with anti-collision lighting visible for at least three statute miles and a remote pilot current under the applicable training and testing requirement. No waiver is required. Thermal contrast is strongest in the hours after sunset, which is when sub-surface moisture separates most cleanly from dry insulation. It applies parcel by parcel: the check comes first, and the SFRA boundary is the gate.
What altitude will you fly over our building?
The ceiling your parcel's authorization allows, or Part 107's 400-foot limit, whichever is lower. No published grid ceiling is quoted for the Frederick area, so altitude resolves through the authorization path. We work the parcel at its centroid and corners rather than quoting the city a single number.
Our roof has no safe access. Does that matter?
That is the usual case for us, and on the older downtown buildings it is often the whole point. Capture runs entirely from outside the structure — no ladders, no penetrations, no personnel on the membrane. Findings arrive as image pairs with the measurement attached, written as scope for your own contractor to price.
Can you keep watch on the property overnight?
No, and we are deliberate about that. Jinki flies scheduled inspection missions; your night coverage stays with your guards and cameras. What we add is a repeatable condition record — the same surfaces captured the same way — so change between missions is measurable rather than argued about.
Who acts on what you find?
Your own contractors and maintenance team. Jinki inspects only and performs no remediation, so the report carries no conflict of interest. Every finding arrives with the image pair and measurement attached.
Do you publish findings or cite us anywhere?
No. You get a mutual NDA by default, findings are prepared for you and your contractors, and we do not publish client sites, tenant names, or findings. The severity-ranked report is written as scope, not as a sales pitch.
