Outside the SFRA, and that changes what we can fly.
Purcellville sits 35.8 NM from the DCA VOR/DME — outside the Washington DC Special Flight Rules Area, unlike nearly every other address we serve in Northern Virginia. 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.

Purcellville sits outside the DC SFRA at 35.8 NM from the DCA VOR/DME, 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. Night scheduling applies to parcels verified outside the boundary, and every parcel is checked before a date is set.

What we inspect in Purcellville.
The small-town commercial core
Low-rise commercial roofs along the main street and the blocks around it — buildings where a slow leak goes unnoticed until a tenant says something. Thermal and visual capture read every roof plane in a single pass.
Industrial and light-manufacturing roofs
Metal and membrane roofs over Purcellville's light-industrial and workshop buildings. Fastener stress, seam failures, and trapped moisture each read differently in thermal, and the report says which is which.
In-town and HOA residential
Established in-town blocks and planned communities on the edges of town. One pass produces a reserve-study-grade record for boards deciding where next year's roof budget goes.
Schools and civic buildings
Long-span roof assemblies where a partial tear-out is the expensive outcome. Aerial thermal scopes the affected area by section before anyone budgets for it.
Large-lot rural property
Barns, outbuildings, and long-roof houses on acreage west of town. 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.
Purcellville, answered.
Purcellville 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 town. Your parcel still gets its own check before we set a date.
Can you fly at night in Purcellville?
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 cell value was returned at the Purcellville 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 rather than quoting the town a single number.
Our roof has no safe access. Does that matter?
That is the usual case for us. Capture runs entirely 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.
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.
