Before this page goes live
- Ten of the twelve photographs are DJI low-quality previews, not full-resolution captures. They will look soft on a full-width tile. Replace them with the originals from the SD card if they still exist.
- Only twelve unique images are available for eighteen marquee slots, so some repeat. More photos would fix it.
- Confirm the scope: replacement, repair, or storm damage.
- Add the redacted permit scan and fill in the five permit points.
- Replace the marked paragraph below with what was actually found on site.

Thirty years on from the last big repair wave
Northridge housing stock is largely post-war tract, and a great deal of it was worked on after 1994.
The north-west Valley was built out fast in the decades after the war, which means whole streets here share an age, a layout and a roof structure. It also means they tend to reach the end of a roof's life at roughly the same time.
A great deal of Northridge was repaired following the 1994 earthquake, and roofs replaced during that wave are now three decades old. Add the fact that this is one of the hottest parts of the basin, with none of the marine layer that moderates the coastal side of the city, and thirty years is a long life for a roof out here.
TO CONFIRM: replace this paragraph with what was actually found on inspection. Age and condition of the existing covering, the state of the underlayment and deck, any active water intrusion, and what made this the right scope.
Six days apart
The same roof from the air, early in the job and once finished.


How the job ran
Four stages, the same sequence on every job we take on.
Assessment
We walked the roof, photographed what we found and put the condition in writing before quoting anything.
Permit
Dearborn Street sits inside City of Los Angeles limits, so this was filed with LADBS rather than the county. TO CONFIRM: permit number and dates.
The work
TO CONFIRM: what was actually done, in the order it happened.
Final inspection
Drainage checked, debris and fasteners cleared from the property, and the permit closed out with LADBS.
Day by day from the air
Six frames from the drone record, in the order the job ran.
