When Codes Have Changed Since Installation

Have Questions Answered About Navigating Post-Install Building Code Updates

Building codes evolve over time. When a roof was installed to code a decade ago, but that code has since changed, adjusters and roofers need a clear path forward.

Repairs and replacements must comply with applicable building codes in effect at the time of work. However, code-related repairs or upgrades may not always be covered by insurance unless specified by the policy. Understanding when code applies—and how it may impact scope or cost—helps ensure accurate estimates and prevents misunderstandings for all parties involved.

What Pros Ask Most

Why do roofing codes change?

Code changes are often driven by:

  • New product standards or testing protocols
  • Updated wind, fire, or impact resistance requirements
  • Local responses to weather events (e.g., Florida’s hurricane codes)
  • Improved energy efficiency or safety regulations
  • Wildfire Urban Interface (WUI)

Who sets the codes I need to follow?

Building codes come from a mix of:

  • Model codes like the International Residential Code (IRC) or International Building Code (IBC)
  • State-level adoption and amendments (e.g., California Title 24)
  • County or municipal enforcement agencies that may impose additional rules

When do new codes apply to a claim or repair?

Generally, if a permit is required, current codes apply—but this may depend on the scope of work, as some jurisdictions (like Florida) apply thresholds such as the 25% or 51% rule.

  • Simple Repairs that don’t require a permit may not trigger code upgrades.
  • Complex Repairs, especially those involving structural elements, large sections, or life safety concerns—typically trigger compliance with current building codes.

Always verify code requirements with the local authority having jurisdiction (AHJ), even if you’ve worked nearby. Building codes can vary block by block, so never assume past experience applies to your current job site.

Where can I access up-to-date roofing code info?

Here are trusted sources for current codes and regional updates:

  • OneClick Code – Provides jurisdiction-specific roofing code details, and code adoption by address
  • International Code Council (ICC) – Model code developed by the ICC; adoption varies by state and may follow different versions (e.g., 2009, 2015, 2021)
  • UpCodes – Easy-to-navigate interface with state and city-specific code links
  • State Building Code Agencies Directory – FEMA – Government-maintained contacts
  • Your local AHJ or permitting office – The final word on enforcement

What if the code change makes a repair impossible?

In some cases, repairing the roof may not be feasible under new code requirements—especially when:

  • Materials or construction methods are no longer compatible
  • Repair doesn’t meet wind uplift or fastening standards
  • Additional layers or materials must be removed to comply
  • Current code requires adding an additional ice barrier layer

Checking the most current building codes, and understanding what the homeowner’s policy does or doesn’t cover regarding code upgrades, helps ensure you’re using the correct and applicable requirements for the repair.

Don’t Get Caught Off Code

Code compliance is the law. Insurance carriers settling claims and roofing professionals are both required to leverage building codes in their work. With codes evolving by region and timeline, staying up to date helps avoid costly do-overs and keeps every claim on solid ground.
