You don’t always know what a Diablo wind event did to your roof until a few days later, when a water stain appears on the ceiling or you spot curled shingles from the driveway. For Dublin and Tri-Valley homeowners, that moment of discovery often arrives after a night of gusts pushing through the Altamont Pass, and the next question is almost always the same: what do I do first?
The order of steps matters more than most homeowners realize. Documentation done before cleanup, an independent inspection before the adjuster arrives, and understanding your policy type before you file can all affect whether you receive a fair settlement or a short one. We’ve been inspecting roofs and attending adjuster meetings across the East Bay since 1976, and we offer free inspections with written documentation you can submit directly to your carrier. Here’s how to work through the process from the moment you discover the damage.
Understand What Your Policy Covers Before You File
California standard homeowners policies cover sudden, accidental damage from named perils: wind, hail, fire, falling objects, and storm debris. They don’t cover gradual wear, deferred maintenance, or damage that predates the storm event. Before filing anything, pull your policy and confirm which type of loss settlement it provides.
Actual Cash Value (ACV)
An ACV policy pays the current depreciated value of your roof minus your deductible. For East Bay homeowners with 1980s or 1990s tract construction, this is a meaningful distinction. A 25-year-old composition shingle roof carries substantial depreciation in an insurer’s calculation, which means the payout can fall thousands of dollars short of what a full replacement actually costs. If your policy is ACV, plan for an out-of-pocket gap.
Replacement Cost Value (RCV)
An RCV policy pays full replacement cost, but not all at once. Insurers typically release an initial payment based on the ACV figure, then issue the held-back depreciation (called the recoverable depreciation) once repairs are completed and documented. Knowing you have RCV coverage changes how you plan for cash flow during the project.
Step 1: Document the Damage Before Anything Else
Before any cleanup, tarping, or debris removal begins, document everything you can see. Photograph the roof from ground level on all four sides. Capture interior evidence including water stains, wet insulation, and damaged ceiling material. Note the date and the storm event that caused it.
One detail East Bay homeowners often overlook: granule accumulation in gutters after a wind or hail event is physical evidence that shingles took impact damage. Photograph your gutters before clearing them. Those granules help establish storm causation when the adjuster arrives. They show the damage is event-related rather than gradual aging.
California law requires insurers to reimburse reasonable temporary repair costs, such as emergency tarping, when you save the receipts. Make those temporary repairs to stop active water intrusion, but don’t make permanent repairs or replace materials until after the adjuster has documented the condition. Permanent repairs before the adjuster visit can eliminate your ability to demonstrate the full scope of damage.
Step 2: Get a Professional Inspection Before the Adjuster Arrives
Insurance adjusters work on behalf of the carrier. Their job is to document damage attributable to the covered event, and they work quickly across a full schedule of inspections. A licensed contractor’s written inspection report prepared before the adjuster visit gives you an independent baseline. It helps ensure damage isn’t missed or attributed to pre-existing wear.
Our team provides free inspections with written documentation, photographs, and a scope of work you can share directly with your insurance carrier as part of the claim file. Having that report in hand when the adjuster arrives creates a more complete record and gives you a professional counterpoint if the adjuster’s estimate comes in lower than the actual scope of work.
For Dublin homes with integrated rooftop solar, the inspection should confirm whether any panels, mounting hardware, or the roof penetrations beneath them were affected. Damage to panels may involve a separate claim pathway through your homeowners policy or the equipment’s product warranty, and the penetrations beneath the mount points are a common entry path for water intrusion that an adjuster without solar experience may not examine.
Step 3: File the Claim & Understand the California Timeline
Once you have your documentation in order, contact your insurer to open the claim. Most California homeowners policies require damage to be reported promptly, and many include a one-year window from the date of loss. Filing sooner preserves evidence and gets an adjuster scheduled before conditions change.
California’s Fair Claims Settlement Practices Regulations set firm timelines: carriers must acknowledge your claim within 15 calendar days and accept or deny it within 40 calendar days of receiving your proof of claim. If your carrier is unresponsive, those regulations give you a basis for escalating. Worth knowing before the adjuster calls: under those same regulations, your insurer can’t require you to use a specific contractor or preferred vendor. You have the legal right to choose any licensed roofing contractor to perform the work.
What Adjusters Look For & What East Bay Wind Damage Actually Looks Like
Adjusters are trained to distinguish storm damage from pre-existing wear, and they document only what they can directly attribute to the reported event. In the Tri-Valley, the most common claim drivers are Diablo wind events and Altamont Pass corridor gusts: lifted shingles with broken seal strips, torn or displaced flashing along roof edges and ridges, and debris impact on field shingles. When the wind direction and recorded gusts from the event date align with the damage pattern on your roof, the causation case is straightforward. NOAA weather records for the specific storm date help when the adjuster’s notes need to establish that connection.
Adjusters will discount granule loss from UV aging, cracking consistent with long-term thermal cycling, and damage patterns inconsistent with the recorded wind direction. A pre-inspection report that maps damage to specific storm mechanics makes the adjuster’s documentation job easier and reduces friction around causation disputes.
If the adjuster’s estimate comes in lower than our assessment, a supplemental claim is the standard next step. Adjusters use Xactimate estimating software, a pricing database that sets line-item costs for materials and labor. If the initial estimate omits items, uses outdated pricing, or underestimates scope, we can prepare a supplemental claim with itemized documentation. Supplemental claims are routine in California, and adjusters expect them on legitimately underestimated losses.
Choosing the Right Contractor & Avoiding Storm Chasers
After a significant wind event, door-to-door contractors appear in East Bay neighborhoods within 24 to 48 hours. Some are legitimate local roofers. Others are storm chasers: out-of-area crews who follow storm paths, collect signatures quickly, and often disappear before warranty issues surface. There are specific warning signs worth knowing before you let anyone on your roof.
Watch for these red flags before signing anything:
- Immediate door-knocking before you’ve filed a claim, often within a day of the event
- Offers to waive or cover your deductible, which is prohibited under California Insurance Code and constitutes insurance fraud; the homeowner can also face exposure under this arrangement
- Requests to sign an Assignment of Benefits (AOB) form, which transfers control of your claim proceeds to the contractor and limits your ability to dispute the scope or settlement
- No verifiable CSLB license; California requires roofing contractors to be licensed, and you can confirm any contractor’s license status and history through the Contractors State License Board at cslb.ca.gov
A contractor familiar with Dublin’s permitting process, building codes, and Title 24 cool-roof compliance requirements eliminates a category of post-claim complications that out-of-area crews commonly create. Title 24 requires that replacement roofing in California meet minimum solar reflectance standards; selecting non-compliant materials after a claim leads to failed inspections and project delays. Our team manages permitting and code compliance for every Dublin roofing project we take on.
If you want a second opinion on an adjuster’s estimate or feel a settlement offer doesn’t reflect the actual scope of damage, a licensed public adjuster (an independent professional who represents policyholders, not insurers) can review the file and negotiate on your behalf. For most straightforward claims, a contractor with experience attending adjuster meetings and preparing supplemental documentation can be enough to reach a fair outcome without that additional layer.
