Bay Area winter storms have changed character. Atmospheric rivers now arrive stacked back to back, dropping enormous volumes over a few days onto ground that is already saturated, and the wind that comes with them takes down limbs off mature oaks that have stood for a century.
We handle the whole sequence: emergency tarping so it stops getting worse, extraction and drying inside, and the documentation your carrier needs. Call +1 (201) 277-9344.
Signs you need storm damage cleanup
If you recognize two or more of these, the problem is already past the point where waiting is cheaper.
Visible roof damage after wind
Lifted, cracked or missing shingles, or a limb resting on the roof. Tarp before the next system arrives.
A new ceiling stain during rain
Water is entering the roof assembly. It is usually well away from where the stain appears.
Water coming in around a window or door
Wind-driven rain through a failed seal or flashing, or a compromised opening.
Water in the garage or crawl space after heavy rain
Surface runoff. Check the drainage path uphill of the building.
A downed limb or tree contacting the structure
Do not attempt removal yourself if it is on the roof or near conductors.
A saturated slope, new cracking or ground movement
Hillside instability. This is a safety issue before it is a restoration one.
What we do in the first visit
Storm work has a strict order of operations. Stop the water coming in, then deal with the water already in.
Emergency tarping and board-up
A properly battened tarp over a damaged roof section, or plywood over a broken window or a compromised door. This is the mitigation step your policy obliges you to take, and skipping it can genuinely reduce what a carrier pays for the resulting damage.
Hazard assessment
Downed conductors, compromised trees still overhead, saturated slope movement, and structural damage from impact. On hillside properties we look uphill as well as at the house.
Water extraction
Everything that came in gets pumped and extracted. See water extraction and removal.
Debris removal
Broken material, wet insulation, saturated ceiling sections and washed-in vegetation out of the building.
Full documentation
Exterior damage, the entry path, the interior damage and the timing — photographed as a single evidence chain, because storm claims live or die on establishing what caused what.
Drying and restoration
Monitored structural drying, then reinstatement once the readings are at standard.
How Lafayette storms actually damage buildings
Roof failure under sustained rain
A composition roof at the end of its service life will keep out an ordinary shower and fail completely under 48 hours of continuous rain with wind driving it uphill under the shingle courses. Flashing at chimneys, skylights and wall intersections is where it usually starts. See roof leak water damage restoration.
Tree and limb impact
Saturated soil plus wind is the combination that brings down mature oaks and bays — the root plate loses its grip in soft ground. On the wooded lots around Happy Valley, Oak Hill Road and throughout Orinda and Moraga, limb strikes on roofs are a routine winter event. Even where the limb does not penetrate, it lifts and cracks shingles and opens the path for water.
Surface runoff and debris flow
Water sheeting off a slope carries leaf litter and soil that blocks area drains and gutters at exactly the moment they are needed most. Homes in the Canyon Road corridor sit where the runoff concentrates, and after a wildfire on nearby slopes the debris-flow risk rises sharply for several seasons because burnt ground repels water.
Wind-driven rain into the envelope
Rain arriving horizontally finds gaps that vertical rain never touches: window head flashing, siding laps, vent penetrations, the underside of eaves. The damage shows up inside as a stain on an exterior wall with no plumbing anywhere near it.
Power loss and the secondary failures
An extended outage stops a sump pump, disables a smart shutoff valve and takes out the heating that was keeping a crawl space pipe above freezing. A surprising number of the storm losses we attend were caused by the outage rather than the weather.
Wildfire zones and water damage
Lafayette sits in a Cal Fire Fire Hazard Severity Zone, with parts of Upper Happy Valley and neighboring Sleepy Hollow in the Very High category. That produces two water damage exposures people rarely think about until they happen.
- Fire suppression water. A structure fire, even a small contained one, is put out with thousands of gallons. The water damage from suppression frequently exceeds the fire damage, and it goes everywhere — down through ceilings, into wall cavities, into the crawl space.
- Exterior defensible-space sprinkler and misting systems. Increasingly common on ridge properties. They sit unused for most of the year, then a failed fitting, a cracked riser or a stuck valve floods a wall or a foundation with nobody home to notice.
The other post-fire risk is on the ground: burnt slopes repel water for several seasons, so the first significant rain after a nearby fire produces far more runoff and debris than the same rain would have before.
Storm insurance — the part people get wrong
The rule of thumb for a standard California homeowners policy is straightforward once you know it: wind and impact damage that opens the building, and the water that then comes in through that opening, is generally covered. Water that came in from the ground is generally not.
| Scenario | Usually covered? | Why |
|---|---|---|
| Wind removed shingles, rain came in through the opening | Yes | Sudden wind damage created the opening |
| A limb punctured the roof and rain followed | Yes | Impact damage from a covered peril |
| A window blew in and rain entered | Yes | Sudden accidental damage to the structure |
| Runoff came under the garage door from the driveway | No — flood policy | Surface water entering at ground level |
| A creek overflowed into the lower level | No — flood policy | Surface water |
| An old roof simply leaked under long rain | Often disputed | Carriers treat wear and deferred maintenance as excluded |
| A power cut stopped the sump pump and water rose | Sometimes, with a sump overflow endorsement | Depends on your specific endorsements |
Before the next storm
- Clear gutters and downspouts in October, not December, and extend every discharge point well away from the foundation.
- Clear and test area drains. Pour a bucket of water into each grate and confirm it goes somewhere.
- Get overhanging limbs assessed by an arborist, particularly deadwood over the roof.
- Check the roof for lifted or missing shingles and failed flashing while it is dry enough to walk.
- Have a battery backup for the sump pump if the property relies on one.
- Photograph the property in good condition — dated exterior photos are the best "before" evidence a claim can have.
You do not need to know what to ask for
You do not have to know whether this is storm damage cleanup, extraction, mitigation or a full restoration — those are stages of one job and sorting out which you need is our work, not yours.
A local person answers
Not a call center selling your emergency on to whoever bids for it.
First question
Has the water stopped? Everything about storm damage cleanup changes depending on whether it is still arriving.
Then we move
60-minute dispatch, and we talk you through the shutoff while the crew is loading.
Free, no-obligation inspection with moisture readings and a written assessment. We bill your insurer directly.
Our storm damage cleanup process
Six steps, documented at every stage, with the daily readings that prove it.
Secure the building
Emergency tarping and board-up so no more water enters.
Assess hazards
Electrical, structural, tree and slope risks, uphill and on site.
Extract and clear
Standing water pumped, debris and saturated material removed.
Document the chain
Exterior cause, entry path, interior damage, timing — as one evidence set.
Dry and monitor
Full drying to a documented standard, including cavities and crawl spaces.
Repair and reinstate
Permanent roof, envelope and interior repairs once readings are at standard.
What drives the price
We are not going to quote a number over the phone — nobody can scope a water loss without walking the property. These are the factors that decide it.
- Emergency securing scope
- Tarping area, roof pitch and height, and how many openings need board-up.
- Extent of water intrusion
- Number of rooms and levels affected, and whether it reached cavities and the crawl space.
- Debris volume
- Tree material, broken building material and washed-in soil all need removal and disposal.
- Access and height
- Steep roofs, hillside lots and limited truck access add labor and equipment.
- Surge conditions
- During a major regional storm event, materials and subcontract availability tighten across the whole East Bay.
- Permanent repair scope
- Roofing, envelope and interior reinstatement are separate from the emergency mitigation phase.
Why choose Water Lafayette for storm damage cleanup
Not the generic badges every restoration site carries — the things that actually change the outcome on this particular job.
Tarping first, at night if the roof is open
Every policy imposes a duty to mitigate, and a roof left open through the next system can reduce what your carrier pays on the additional damage. We batten properly rather than weighting a sheet.
We assess uphill, not just the building
On a Lafayette hillside the risk after a storm includes saturated slope movement and compromised retaining walls above the house. That gets looked at before anyone works below it.
One evidence chain, exterior cause to interior damage
Wind and impact damage are covered; surface runoff is not. Documenting them as one sequence is what stops a covered portion being denied alongside an excluded one.
We know the post-fire hydrology here
Burnt slopes repel water for several seasons, so the first serious rains after a fire above you produce far more runoff and debris than the same rainfall would have before.
Storm surge does not change the standard
When the whole county calls at once we triage by severity and tell you honestly where you are — rather than booking everyone for a slot we cannot keep.

Storm Damage Cleanup FAQs
Can you tarp my roof tonight?
That is the priority when a storm has opened a roof, and yes, we do it after dark with work lights where it is safe to be up there. If wind speeds or lightning make roof access genuinely unsafe we will say so, protect the interior with containment and extraction, and tarp at first light. Emergency tarping is a covered mitigation cost on virtually every policy — keep the invoice and the photographs.
Is storm damage covered by homeowners insurance in California?
Wind and impact damage that opens the building, and the water that then enters through that opening, is generally covered. Surface water entering at ground level — runoff under a garage door, creek overflow, a saturated yard — is generally excluded and needs a separate flood policy. Long-term roof wear that finally leaked under sustained rain is often disputed as deferred maintenance. We document the exterior cause and the entry path as one evidence chain so the covered portion is not denied along with the excluded one.
A tree limb hit my roof. What do I do first?
Stay out from under it and keep everyone away from any conductor the limb may be touching. Do not attempt removal from a ladder. Call us to secure the opening and extract the water, and if the limb is large or in contact with power lines we coordinate the arborist and PG&E rather than working around it. Photograph everything from a safe distance before anything is moved.
Why does my house flood during heavy rain when it never used to?
Usually because a drainage path changed without anyone noticing. A silted French drain, a blocked area drain, landscaping that regraded the fall toward the house, a downspout extension that got removed, or a neighboring property that redirected its runoff. Storms have also intensified — the same drainage that coped with historical rainfall can be overwhelmed by an atmospheric river dropping several inches in a few hours onto saturated ground.
Does a nearby wildfire increase my water damage risk?
Yes, in two ways. Burnt slopes repel water for several seasons, so the first significant rains produce much heavier runoff and debris flow than the same rain would have before. Separately, fire suppression itself causes major water damage — a structure fire is put out with thousands of gallons that go through ceilings, into wall cavities and into the crawl space, and that water damage frequently exceeds the fire damage. Exterior defensible-space sprinkler systems that sit unused most of the year are another common failure point.
