A large HOA portfolio, every roof on the same record.
South Riding runs across townhome rows, single-family sections, community centers and pools, a commercial center, and the flex and industrial buildings at the community's edge. All of it sits inside the Washington DC Special Flight Rules Area, so we verify your parcel's airspace before we promise a date, then fly radiometric thermal and high-resolution visual capture across 100% of the surveyed surface.

South Riding sits 22.0 NM from the DCA VOR/DME, inside the DC SFRA, so operations run under FAA authorization with NOTAM discipline. Inside the SFRA the standing UAS security NOTAM is VMC-only and bars night, so flights are scheduled in daytime and twilight windows. With no cell value returned for this area, altitude is set by the authorization itself and by Part 107's 400-foot limit, whichever is lower.
HOW THIS IS READ → THE AIRSPACE GUIDE- 22.0NM

- 100%
- Coverage per single mission — every section surveyed
- 48HR
- Findings report targeted within 48 hours of capture — geolocated and severity-ranked
- Radiometric

What we inspect in South Riding.
Cluster roofs across the association
South Riding's housing is organized into clusters and sections, each with its own build era and roof detail. Capturing them under the same conditions on the same day is what makes the comparison defensible — where a board's replacement sequence is derived from measured condition rather than from the loudest complaint.
Townhome rows
Attached rows concentrate risk: a shared valley, a party-wall flashing, or one failed transition affects several owners at once. One pass maps the full row so the finding can be scoped as a single repair instead of a series of adjacent complaints.
Community centers and pools
Pool buildings, bathhouses, and community centers carry occupancy, mechanical equipment, and the association's event calendar. Thermal capture reads roof moisture and envelope losses over occupied space, so work can be sequenced into a shoulder season rather than forced into an emergency window.
The commercial center
Low-slope roofs over retail and office bays with dense rooftop equipment and parapet detailing. Findings are geolocated by bay, which lets ownership separate structure-wide action from work that belongs to a single suite.
Flex and industrial buildings
Warehouse and flex roofs around the community's perimeter, where large uninterrupted membrane areas hide trapped moisture best. Thermal separates wet fields from dry ones across the whole deck, not just at the spots someone already suspected.

South Riding, answered.
Is South Riding inside the DC SFRA, and can you fly here?
Yes, and yes. South Riding measures 22.0 NM from the DCA VOR/DME, inside the 30-mile Special Flight Rules Area, and it is core service area 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.
What altitude will you fly over our section?
Whichever the FAA's ceiling for your parcel allows, or Part 107's 400-foot limit, whichever is lower. The South Riding area returned no grid cell value, which means altitude is resolved through the authorization path rather than an automated ceiling — so we pull the parcel check at the centroid and corners and put the profile in writing before the flight. Where our profile needs to sit above a cell ceiling, the request goes through a manual FAA path and we file early.
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 peak in the hours after sunset, so for parcels verified outside the SFRA we schedule night capture; for South Riding we plan around twilight and dry-day windows, which still produce strong ΔT separation on a wet roof.
Our roofs were installed across several build phases. Does that change the method?
It shapes the read. Different phases mean different membrane systems, details, and ages, so we capture the community in coordinated missions and report by phase as well as by building. That gives a board a phase-by-phase comparison instead of one averaged number for the whole association, and it makes the replacement sequence easier to defend.
How does this help a reserve study or capital budget?
Reserve projections depend on condition, and condition is what the report measures. You receive geolocated findings with ΔT measurements, severity ranking, and a recommended order of action — a date-stamped condition of record to compare against the next cycle, and the evidence behind any line item a board puts in front of owners.
How does this work with our existing roofer or engineer?
Findings are written to become scope: locations, extents, and priority for each item, with the imagery and measurement attached. Jinki inspects only and performs no remediation, so the report carries no conflict of interest — your contractor prices measured condition instead of a guess.
Do you publish findings or cite South Riding anywhere?
No. You get a mutual NDA by default, findings are prepared for you, your board, and your contractors, and we do not publish client sites, addresses, or findings. The severity-ranked report is written as scope, not as a sales pitch.
