Coverage breakdown
Policy form
Mercury Insurance: Proprietary form
Nationwide: Nationwide offers a Brand New Belongings option and an Better Roof Replacement option in many states.
Why it matters: the policy form is the contract. Two carriers can both call a product "homeowners insurance" and have meaningfully different definitions of "covered peril," "actual cash value," and how losses are settled.
Roof settlement
Mercury Insurance: Settlement basis varies by state and program. Confirm at bind.
Nationwide: Nationwide offers a Better Roof Replacement endorsement in many states that pays to rebuild with stronger, safer materials after a covered loss. Default settlement basis varies by state. Confirm at bind.
Why it matters: on a 15-year-old asphalt roof, an ACV or schedule-by-age settlement can leave the homeowner with five-figure out-of-pocket costs after a hailstorm. Read more about RCV vs ACV.
Wind / hail deductible
Mercury Insurance: Varies by state and program.
Nationwide: Varies by state and program.
Why it matters: percentage deductibles (1%–5% of Coverage A) are common in hail- and hurricane-prone states. On a $500,000 dwelling, a 2% wind/hail deductible is $10,000 — the first $10,000 of any wind or hail loss.
Water backup
Mercury Insurance: Available as endorsement
Nationwide: Available as endorsement
Ordinance or law
Mercury Insurance: Typically included at 10% of Coverage A; higher limits available.
Nationwide: Included (standard)
Which policy fits which homeowner
We don't rank carriers. The right choice depends on your home, your roof, your state, and the specific endorsements you add. A few coverage-driven considerations:
- If you have a roof over 10 years old, the roof settlement basis matters more than the premium difference.
- If you live in a hail- or hurricane-prone state, check the wind/hail deductible structure on both quotes.
- If your home was built before 1990, default 10% ordinance or law coverage is often insufficient — ask about higher limits.
- If you have a finished basement, sump pump, or septic, water backup coverage is worth pricing on both quotes.
