What to Do in the First 24 Hours After Water Damage

Storm damage restoration in Northern Virginia means dealing with several disasters at once — wind that tears at the roof, rain driven through the openings it creates, flooding from overwhelmed storm drains and overflowing creeks, and the water intrusion that follows all of it. The work breaks into a clear sequence: secure the property against further weather, extract and dry the water before mold starts, then repair the structural damage. For homeowners across Fairfax, Loudoun, Arlington, and Alexandria after a summer derecho or a tropical system, here is how it goes and what to do first.

Northern Virginia gets a particular mix of storm threats. Summer brings fast-moving derechos and severe thunderstorms with damaging straight-line winds; late summer and fall bring the remnants of tropical storms and hurricanes pushing up from the coast; and year-round, heavy rain overwhelms storm drainage in the region's rapidly developed areas, flooding basements that never flooded before. Each produces a different damage profile, but they share one urgent commonality: water gets inside, and water on a clock grows mold.
Once the storm has passed and it is safe to assess:
NoVA storms produce a recognizable set of damage types, often several together:
The process mirrors any serious water loss, with an added emphasis on securing the structure first. Crews start by stopping the ongoing intrusion — tarping the roof, boarding openings — so the inside is no longer getting wetter. Then comes water extraction, followed by structural drying with commercial air movers and dehumidifiers and daily moisture monitoring until the structure reaches a verified dry standard. Antimicrobial treatment prevents mold in the affected areas. Finally, reconstruction repairs what the storm and water destroyed. The mechanics of the drying phase are the same ones in our professional drying and dehumidification guide; the difference with storms is the urgency and scale of securing the building envelope first.
The homes that fare worst after a regional storm are usually the ones where water got in and sat for two or three days while the owner waited for a roofer, an insurer, and a tree service to all show up. Extract and dry first; the structural repairs can follow on a slower clock, but the water cannot wait.
It depends on how the water got in, and this is where storm claims get tricky. Wind damage and the water that enters through wind-created openings — a torn-off shingle, a tree through the roof — are typically covered by a standard homeowners policy as sudden storm damage. But flooding from rising water outside — an overflowing creek, storm surge, water rising up from saturated ground into your basement — is generally not covered by homeowners insurance and requires separate flood insurance through the NFIP. The same storm can produce both a covered wind-driven roof leak upstairs and an uncovered flood in the basement. Documenting which water came from where — wind-driven intrusion versus rising flood — is what determines coverage, so photograph the source of each, not just the damage.
You cannot stop the storm, but you can shrink what it costs you. Keep the roof maintained — loose or aging shingles are the most common storm intrusion point. Clear gutters and downspouts so heavy rain drains away from the foundation rather than pooling against it. Install or maintain a sump pump with battery backup, since storm power outages are exactly when a pump fails. Grade soil away from the foundation and address any drainage that sends water toward the house. Trim trees and remove dead limbs near the structure before storm season. And know your flood risk: check your address on the current FEMA flood map and carry flood insurance if you are anywhere near a waterway or a low point. Our water damage prevention guide covers the shut-off and monitoring basics that help here too.
When a derecho or tropical system hits the whole region, restoration demand spikes for everyone at once, and the homes that get help first are the ones that call first and have already mitigated to stop the water. This is the case for knowing your emergency water damage response plan before the storm — where your shut-offs are, who you call, and how to tarp and board until the crew arrives. Preparation is what gets you to the front of the line when everyone needs help simultaneously.
After a big regional storm, restoration capacity is the bottleneck, not the work itself. The homeowner who documented the damage, tarped the roof, and called within the hour is dry days before the one who waited to "see if it gets worse." It always gets worse.
Wind damage and water that enters through wind-created openings — a damaged roof, a tree through the wall — are typically covered as sudden storm damage. Flooding from rising water outside the home is generally not covered and requires separate NFIP flood insurance. The same storm can cause both a covered and an uncovered loss.
Check for safety hazards like downed lines and structural damage, document everything with photos and video before cleanup, make temporary repairs (tarp, board up) to stop further damage, and call your insurer and a restoration company quickly — extraction needs to start before mold begins within 24 to 48 hours.
Securing the property and extracting water happen in the first day or two; structural drying runs three to five days or more; reconstruction varies with the damage, from days to weeks or longer. Fast response shortens the whole timeline and limits mold.
Rising-water flooding from a storm is generally excluded from homeowners policies and needs separate flood insurance. Water that comes in through wind damage to the roof or windows is usually covered. Documenting how the water entered determines which applies.
