A planned city read roof by roof, village by village.
Columbia sits 22.2 NM from the DCA VOR/DME — inside the Washington DC Special Flight Rules Area. Its common property, village centers, office campuses, and flex parks are all SFRA parcels, so we verify your address before we promise a date, then fly radiometric thermal and high-resolution visual capture across 100% of the surveyed surface.

Columbia sits 22.2 NM from the DCA VOR/DME, inside the 30-mile DC SFRA. Controlled airspace requires prior FAA authorization, and inside the SFRA the standing UAS security NOTAM is VMC-only and bars night, so flights are scheduled in daytime and twilight windows. Altitude is set by your parcel's cell ceiling or Part 107's 400-foot limit, whichever is lower. The DC Flight Restricted Zone is out of scope for our aerial work, and we say so at intake.

What we inspect in Columbia.
Association common property and village centers
Columbia's common property carries an unusual load: pools, community buildings, and the village centers themselves, each with its own roof assembly and its own budget line. One pass produces a reserve-study-grade record a board can act on without commissioning separate inspections building by building.
Office and commercial campuses
Low-slope office roofs across the downtown core and the gateway campuses along the parkways. Trapped moisture under an intact membrane is invisible from the parking deck and unambiguous in thermal — located by section, before it becomes a tear-out.
Industrial and flex parks
Metal and membrane roofs over Columbia's light-industrial and flex stock. Fastener stress, seam failures, and wet insulation each read differently, and the report says which is which so your contractor prices the right repair.
Planned-community and townhome clusters
The village structure means long runs of attached roofs captured under identical conditions in a single mission. Findings rank by building and by section, so a board can see which clusters are wet now and which can wait a budget cycle.

We come back with the parcel's position inside the SFRA, the authorization path, and the flight windows that apply — before anyone talks about scheduling.
Columbia, answered.
Can you fly in Columbia? Columbia is inside the DC SFRA.
Yes. Columbia measures 22.2 NM from the DCA VOR/DME against the 30-mile boundary of the Special Flight Rules Area, so it sits inside the SFRA and outside the smaller Flight Restricted Zone. 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.
What altitude will you fly over our building?
Whatever your parcel's authorization allows, or Part 107's 400-foot limit, whichever is lower. No cell value was returned at the Columbia area, so there is no published grid ceiling to quote — altitude resolves through the authorization path instead. We pull your parcel's position at its centroid and corners rather than quoting the town a single number.
Can you fly at night to catch thermal contrast?
Inside the SFRA, no — the standing UAS security NOTAM limits operations to clear-weather daylight. Thermal contrast does build after sunset, so for parcels verified outside the SFRA we schedule night capture; for Columbia we plan twilight and dry-day windows, which still separate wet from dry roof sections cleanly.
Do you fly inside the DC Flight Restricted Zone?
No. Aerial work inside the DC FRZ requires a TSA/FAA airspace waiver process, and that airspace is out of scope for us — we say so at intake rather than partway through a schedule. Columbia is outside the FRZ, so this does not affect a Columbia parcel, but we state the line plainly because it governs where we will and will not fly.
Our association manages dozens of buildings. Is that one mission?
Usually yes, and it is the case we see most in Columbia. We capture the whole roof field under one set of conditions, then rank findings by building and by section. Findings arrive as scope for your own roofing contractors — Jinki performs no remediation, so the report carries no conflict of interest.
Do you publish findings or name us anywhere?
No. A mutual NDA is standard, 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.
