Earthquake and windstorm: find the coverage gap before calculating a payment

What you will learn

• Separate earthquake, wind and flood coverage inquiries.
• Identify the clause or policy needed to close a stated gap.
• Calculate a percentage deductible using its supplied base.

Before you start

Before you start, review Lesson 09: Map a homeowners loss to the right coverage, Lesson 13: Commercial property: build the package, classify the loss. You can return to those lessons when a term or step is unfamiliar.

A property policy is not an every-disaster policy

A home can be insured against several causes of loss and still have an important earthquake or windstorm gap. Neither a large dwelling limit nor a label such as special coverage answers every peril question. First identify the cause of the damage. Then examine the base policy and endorsements. Only after finding an applicable coverage grant should you calculate limits and deductibles. A deductible cannot turn an excluded peril into an insured one.

Look specifically for earthquake protection

Standard homeowners and renters protection generally does not cover direct earthquake damage. Earthquake coverage may be arranged through an endorsement or a separate policy. The III discussion and NAIC guide describe both routes. Do not assume buying one route includes every property category or expense. Check the building, belongings and loss-of-use selections, their limits, deductible terms and exclusions. An endorsement changes specified terms; it does not erase every other condition in the contract.

Apply the exclusion before the dollar limit

A fictional policy insures a dwelling for $350,000 but expressly excludes direct earthquake damage, and no earthquake coverage was added. An exercise stipulates that shaking alone caused $28,000 of structural damage. The large dwelling limit does not supply missing earthquake coverage. Now change the facts: an attached endorsement covers that direct earthquake loss, subject to its stated deductible. That changes the coverage analysis. The cause and added protection—not the headline dwelling limit—made the difference.

Do not give every loss the disaster's name

A disaster can produce different causes of damage. Shaking damage and a later fire are not interchangeable facts. The III earthquake discussion notes that standard policies generally cover fire following an earthquake, even though direct earthquake damage is excluded. The actual wording and cause still matter. Do not conclude that every loss during an earthquake is excluded, or that a possible fire exception also pays for the earlier shaking damage. This lesson does not resolve complex competing-cause disputes.

Windstorm may already be covered—or may be excluded

Windstorm and hail are commonly covered under homeowners forms. But the NAIC guide explains that some policies, particularly in coastal areas, exclude them and may require separate protection. Therefore neither every home policy covers wind nor wind always needs a separate policy is reliable. Read the actual grant and exclusions, including endorsements. A policy's geographical setting may prompt closer inspection, but it cannot replace the contract facts in an exercise.

Compare three supplied arrangements

Home A's supplied policy covers windstorm damage and has no applicable wind exclusion. Home B's policy expressly excludes windstorm, with no additional wind coverage. Home C has the same exclusion in its home policy but also carries a separate policy covering the stipulated wind loss. A points to its home policy, B has the described gap, and C points to its separate wind policy. These outcomes follow from the supplied wording, not from a universal rule about every insurer.

Wind and flood still require different checks

If a storm produces both wind damage and rising floodwater, do not assign all damage to whichever policy has the largest limit. Identify the cause of each loss and apply the relevant contract. For a simplified exercise, suppose wind removes roof materials while floodwater separately damages ground-level property; the policies expressly separate those perils. Analyze each stated cause under its corresponding grant. Real causation disputes can be more complicated, and a storm's name alone does not settle them.

Read the deductible's basis, not just its percentage

A catastrophe coverage arrangement may use a deductible that differs from the ordinary deductible. When a question supplies a percentage deductible, identify exactly what amount the percentage applies to. A percentage of a stated building limit is not a percentage of the loss. Also check which event triggers it and whether property categories have separate treatment. This lesson supplies numbers for practice; it does not teach one required earthquake or windstorm percentage.

Use a fully stated exercise rule

An exercise endorsement covers the specified earthquake damage and sets its building deductible at 4% of a $300,000 building limit. It directs you to subtract that deductible from a covered $30,000 building loss, with no other adjustment. The deductible is $12,000: 0.04 × $300,000. The remaining amount is $18,000. Using 4% of the $30,000 loss would calculate $1,200, but that uses the wrong base. Neither percentage is a claim about every real earthquake policy.

Pause and predict

An exercise specifies a 5% earthquake deductible based on a $300,000 coverage amount. The damage is $40,000. Which base produces the deductible, and what error would using the damage amount create?

Use the same reading sequence for both perils

1. Identify the cause of the particular damage.
2. Locate the base grant and any exclusion.
3. Check endorsements or a separate policy that may address the gap.
4. Identify which property or expense is actually selected.
5. Apply the stated trigger, deductible basis, limits and remaining conditions.

Keep coverage selection separate from payment arithmetic.

Try finding the missing protection

1. Does a $350,000 dwelling limit override the exercise's earthquake exclusion?
2. Name two ways earthquake protection may be arranged.
3. Which home in the A/B/C wind example has the stated coverage gap?
4. Does a separate wind deductible mean wind is excluded?
5. In the 4% exercise, what is the deductible and the remaining amount?
6. Does a storm's name prove wind caused every item of damage?

Check cause, grant and calculation in order

What to remember

Earthquake often needs added protection; windstorm may be included or excluded. Read the actual arrangement instead of assuming. Identify the cause and coverage first, then calculate using the stated deductible base and limits. Neither a disaster label nor an impressive policy limit proves the loss is covered.
