The upper Shenandoah Valley, well outside the boundary that shapes our DC work.
Winchester measures 56.1 NM from the DCA VOR/DME — more than twenty-six miles outside the Washington DC Special Flight Rules Area. No SFRA procedures apply at the parcel level, so night capture is available on parcels verified outside the boundary, and the same lighting condition covers civil twilight. A regional airport serves the area, and where a parcel falls inside controlled airspace, prior FAA authorization under 14 CFR 107.41 applies. We pull your parcel's cell at the centroid and corners before any date is set, then fly radiometric thermal and high-resolution visual capture across 100% of the surveyed surface.
- FROM DCA
- 56.1 NM
- STANDING
- Outside the DC SFRA
- POSTURE
- Served — no SFRA procedures apply at the parcel
- CELLS
- Per-parcel. No cell value was returned at the Winchester area, so there is no published grid ceiling to quote for the town — we pull your parcel's cell at the centroid and corners and resolve altitude through the authorization path.

- Frederick County, VA
Winchester sits 56.1 NM from the DCA VOR/DME, more than twenty-six miles outside the 30-mile DC SFRA, so the standing UAS security NOTAM that governs our work closer to Washington does not reach this town. 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. The same lighting condition covers civil twilight. Night scheduling applies to parcels verified outside the boundary, and the parcel check comes first. Where a parcel falls inside controlled airspace around the area's regional airport, prior FAA authorization under 14 CFR 107.41 applies, and no date is promised before that authorization is in hand. The DC FRZ is out of scope for our aerial work — we do not fly there.

What we inspect in Winchester.
The historic downtown commercial core
Masonry commercial buildings along the walking mall and the blocks around it — parapets, patched membrane, and mechanical curbs that make a ladder survey slow and a leak hard to localize. One pass reads every roof plane on a block in the same conditions, so the record is comparable building to building.
Food processing, packaging, and manufacturing
Real local industry, and roofs where production scheduling is the constraint rather than the survey. Capture runs entirely from outside the building — no roof access, no ladders, no line stopped — and the thermal read finds wet insulation and connections running warm by section.
Hospital and institutional buildings
Long-span and multi-level roof assemblies where a roof problem competes with everything else on the plant list. Aerial thermal scopes the affected area by section, with the image pair and measurement attached, so facilities can rank the work against the budget they actually have.
Multifamily roofs across the city
The assemblies where a slow leak reaches a ceiling before anyone gets up on the roof. A dated, geolocated record names the building and the section, and gives an owner a basis for the next reserve cycle instead of a contractor's opinion.
Large-lot rural and agricultural property
Barns, outbuildings, and long-roof houses on acreage across Frederick County. Assemblies at this scale are faster to survey from the air than from a ladder, and nothing on the property has to be moved, staged, or manned to get the record.

We come back with the parcel's position relative to the SFRA boundary, the authorization picture where controlled airspace applies, and whether night capture applies to it — before anyone talks about scheduling.
Winchester, answered.
Winchester is well outside the DC SFRA. What does that change?
Three things. No SFRA procedures apply at the parcel level, night capture is available 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 town. Where a parcel falls inside controlled airspace around the area's regional airport, prior FAA authorization under 14 CFR 107.41 still applies, and we confirm that before we commit to a date.
Can you fly at night in Winchester?
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, and the same lighting condition covers civil twilight. Thermal contrast is strongest in the hours after sunset, 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 cell value was returned at the Winchester area, so there is no published grid ceiling to quote for the town — we pull your parcel's cell at the centroid and corners and resolve altitude through the authorization path. We do not publish a single number for Winchester.
Does the regional airport affect our survey?
Where a parcel falls inside controlled airspace, prior authorization from the FAA is required under 14 CFR 107.41, and we confirm whether yours does before any date is set. It sets the authorization requirement, not the deliverable — the profile is planned inside what the authorization allows, and we never promise an outcome or a date before the authorization is in hand.
We run a food-processing plant. How do you work around production?
Capture happens entirely from outside the building — no roof access, no ladders, no production stop. Missions are scheduled in windows that work around your shifts, and findings arrive as image pairs with measurements attached, written as scope for your own contractors to price. Jinki inspects only and performs no remediation.
Our roof has no safe access. Does that matter?
That is the usual case for us. Capture runs from outside the building — 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.
