7 Coverage Gaps Most Homeowners Don't Know They Have
Most coverage failures aren't dramatic — they're small omissions that compound. Here are the seven that show up most often.
A coverage gap rarely announces itself. It's the difference between what you assumed and what the policy actually says — invisible until a claim drags it into the light. These seven are the ones we see most often when reading real policies.
1. An underinsured dwelling limit
Rebuild costs have outpaced almost every policy limit. If your dwelling coverage was set when you bought the home and never adjusted, it's likely thousands below today's cost to rebuild — and a coinsurance clause can penalize you even on a partial loss.
2. Actual cash value on the roof
Even when the dwelling is covered at replacement cost, the roof is often settled at actual cash value, depreciated by age. It's a one-line distinction that can halve a roof payout.
3. No sewer or drain backup endorsement
Standard policies exclude water that backs up through sewers and drains — one of the most common and expensive home water losses. It requires a specific, inexpensive endorsement most people never add.
4. Missing ordinance or law coverage
After a major loss, you must rebuild to current building codes — which can cost far more than the original construction. Without ordinance-or-law coverage, that code-upgrade cost comes out of your pocket.
5. Personal property sub-limits
Jewelry, firearms, electronics and collectibles usually carry low category sub-limits — often a few thousand dollars total — regardless of your overall contents limit. High-value items need scheduling.
6. Inadequate loss-of-use coverage
If your home is unlivable for a year during a rebuild, your loss-of-use limit has to cover a year of alternative housing. Many are set too low for how long real rebuilds actually take.
7. No flood coverage in a 'low-risk' zone
A large share of flood claims come from outside high-risk flood zones. Because homeowners policies exclude flood entirely, 'low risk' too often becomes 'no coverage.'

Frequently asked questions
What is the most common homeowners insurance gap?
An underinsured dwelling limit. Because rebuild costs have risen faster than most policy limits were updated, a large share of homes are insured below what it would actually cost to rebuild them today.
Is sewer backup covered by homeowners insurance?
Usually not by default. Water backing up through sewers or drains is typically excluded and requires a specific endorsement, which is generally inexpensive relative to the cost of the damage it covers.
What is ordinance or law coverage?
Coverage for the extra cost of rebuilding to current building codes after a covered loss. Without it, mandatory code upgrades during a rebuild — wiring, plumbing, structural — become an out-of-pocket expense.
