Will Insurance Pay for a New Roof in NZ?

Will insurance pay for a re-roof?

House insurance generally covers sudden damage, such as a storm lifting sheets, but excludes gradual deterioration and wear and tear ¹. The Insurance & Financial Services Ombudsman notes gradual damage is a common reason claims are declined ². Budget an old, rusting roof as maintenance: a 3-bedroom re-roof costs $18,000–$30,000 ⁴.

Usually not for an old, worn-out roof. NZ policies tend to cover sudden damage, like a southerly lifting sheets. They don't cover slow wear, tear and rust ¹².

Frequently asked questions

If my old roof leaks in a storm, am I covered?

Maybe, for sudden damage inside. Fixing a roof that was already worn out is unlikely to be covered ³.
