Ponding becomes an indoor problem
Many warehouses have wide, low-slope roofs that depend on drains, scuppers and gutters to move rain away. Debris, ice or a failed component can slow that movement. Water then collects in shallow ponds that add weight and press on seams, penetrations and flashing.
When water finds a way through, it rarely lands in a convenient place. It may travel along decking, drip at a joint far from the original weak point and fall onto racked product twenty or thirty feet below. Because the water enters from above, the first sign may be a stained ceiling panel, a drip over a rack bay or a small puddle that grows.
Collapsed ductwork and debris coated in dust inside a warehouse. One example of what this stage can look like; it is not a job connected to this site.

After the water stops
Once the roof is tarped or patched and the interior is safe, attention turns to what got wet. Insulation above a ceiling grid, acoustic panels, wall cavities near parapets and the top layer of palletized goods are common problems. Slab water is usually the easiest part of the cleanup, because extraction removes most of it. The material that held water above the floor is the harder part.
Keep a record of drip locations, the date and time of the storm and any photos of the roof. These details help separate a one-time storm event from a long-standing maintenance issue, which can matter when an insurer asks questions.
Common questions
Is a roof leak covered like other water damage?
Coverage depends on the policy and the cause. Ask the insurer early and keep records.
Should wet ceiling tiles be removed right away?
They often hold water and can fall. Assess the hazard before touching them.
