Detailed answer
Factors That Change The Recommendation
It's becoming more common - insurers tightening up on aging roofs, particularly in markets they're trying to exit or rebalance. The trigger isn't always 'your roof is bad.' Sometimes it's age alone, even if the roof is performing fine. Knowing where you stand before the renewal letter arrives is the move.
Carriers vary widely. Some refuse to renew on roofs over 20 years old regardless of condition. Others require an inspection and condition report from a licensed inspector. Some increase premiums or shift to actual-cash-value coverage instead of replacement-cost value - which can leave you significantly underinsured if a storm hits. Coastal homeowners (Cape May, Florida Atlantic, hurricane corridors) face the strictest rules. California has its own market constraints driven by wildfire risk, with some carriers exiting entirely. Knowing your carrier's specific roof-age policy matters - it's in the fine print, not the marketing.
If You're In California Or New Jersey
California homeowners face a tightening property insurance market with several major carriers limiting new policies; aging roofs become an easy non-renewal trigger. New Jersey coastal homeowners (Cape May County, Atlantic, Ocean) deal with storm-zone underwriting; inland is less restrictive but the trend is moving everywhere.
