What to do about a metal roof in the Lankershim corridor in the first forty-eight hours, and what to leave until Monday.

After a storm the useful work happens in the first two days, and most of it is documentation rather than repair. This is what to do about a metal roof in the Lankershim corridor once the wind drops.

What actually matters

Metal rarely wears out. What fails is the fixing. An exposed-fastener panel is screwed through its face, and every screw carries a rubber washer that hardens in this sun. After fifteen summers those washers shrink, the screws back out, and a roof with two thousand fasteners has two thousand small opportunities to leak.

What to do in the first forty-eight hours

Document before you touch anything: wide photographs to establish the property, then close photographs of each item of damage, all dated. Thermal movement is the detail that decides everything. A long panel in this climate grows and shrinks measurably between a July afternoon and the following dawn, and a fixing system that does not allow for that movement will fight it until something gives. A tarp fixed through sound covering creates damage that was not there before.

How the Lankershim corridor changes the answer

Along the Foothill corridor the buildings are largely commercial: big low-slope areas carrying rooftop plant, walked on regularly by trades who are not thinking about the membrane. Dust off the slopes settles on the surface and washes into the drainage with every storm. Older commercial stock with large low-slope areas, parapets, and equipment that needs servicing.

What we look at on an inspection

Fastener condition on any exposed-fix section, including washer hardening
Clip engagement and any sign of thermal binding along standing seams
Seam integrity down the full run, not only at the visible ends
Coating condition, with particular attention to cut edges and scratches
Sealant at penetrations, end laps and every transition
Panel oil-canning, which is cosmetic but can point to fixing problems
Corrosion at eaves, cut edges and any point where dissimilar metals meet

Common questions

Should I get a tarp on it straight away?

Only once it is photographed, and only if it can be fixed without putting new holes through sound covering. A badly fixed tarp creates damage that was not there before.

How soon do I need to report it?

Check your policy, because most impose a reporting window. Reporting early costs nothing and protects the claim.

The honest summary

Metal is the longest-lived option available here, but only if the fixing system suits the movement. Ask how the panels are held down before you ask what they cost. In the Lankershim corridor the thing to watch is membrane condition around the rooftop plant, parapet terminations, and every drain and scupper on the roof.
