Code-required items on a roofing insurance claim are the materials and installation steps your local building code mandates that the original roof may not have had — and insurers often owe for them, not as a favor, but because most policies include coverage that pays the added cost of bringing a damaged roof up to current code. The trick is knowing which items typically apply and proving the code actually requires them.
The Four Items That Show Up Most Often
These aren't universal — code adoption varies by state and even by county — but they're the ones adjusters see (and sometimes miss) again and again.
- Drip edge: Many editions of the International Residential Code (IRC), which most states use as the base code for residential roofing, require drip edge at eaves and rakes under the underlayment. If the old roof didn't have it, adding it during a covered repair is often a code-driven line item, not a betterment.
- Ice and water shield: In regions with a history of ice damming, code typically requires a self-adhering ice barrier extending a set distance up from the eave. Whether it applies depends on your local climate zone and the specific code section your jurisdiction has adopted — this isn't a blanket requirement everywhere.
- Attic ventilation: Code sets a minimum net free ventilating area relative to attic floor space (commonly expressed as a ratio like 1/150 or 1/300, depending on vapor barrier conditions). If the existing ridge or intake vents don't meet that ratio, bringing them up to spec is a code item.
- Decking: Re-decking requirements, upgraded nailing patterns, or fastener schedules for wind resistance are frequently tied to local amendments rather than the base IRC — Florida and coastal wind-borne debris regions are a good example of jurisdictions with stricter decking and fastening rules than the national base code.
How Code Turns Into Coverage
Most homeowner policies include some form of Ordinance or Law coverage — sometimes labeled 'Building Ordinance or Law' or similar — that pays the additional cost to comply with current building code when a covered loss triggers a repair or rebuild. The coverage generally has to be triggered by an actual code requirement, usually documented through a permit or building department correspondence, not just a contractor's preference for better materials. Limits, percentages, and exact wording vary significantly by carrier and policy, so the specific dollar amount available isn't something you can assume — it has to be checked in that homeowner's declarations page. This is general information, not legal or financial advice; when the language is ambiguous, that's a conversation for the homeowner, their agent, or an attorney, not a guess on a job site.
Documenting the Local Code So the Adjuster Can't Argue
The single biggest reason code items get denied isn't that they're wrong — it's that they're undocumented. An adjuster who can't verify the code citation has every reason to push back.
- Pull the permit for the job and keep a copy in the claim file — it's proof the local Authority Having Jurisdiction (AHJ) is involved.
- Cite the specific code section your jurisdiction has adopted, not a generic national reference — code amendments differ by state and county, so 'the IRC requires it' isn't as strong as naming the local section.
- If there's any doubt, get it in writing from the building department. A short letter or plan-review comment confirming the requirement is hard to dispute.
- Photograph the non-compliant condition before it's covered up — missing drip edge, insufficient vent area, thin or damaged decking — so the before-and-after tells the story on its own.

Where This Fits Into Your Workflow
Code items are one of the more defensible pieces of a supplement because they're not subjective — the code either requires the item in that jurisdiction or it doesn't. That makes them worth tracking consistently across every claim, not just the ones where you remember to check. Building a repeatable process for citing local code, attaching permit documentation, and referencing the right policy language is what separates a supplement that gets approved on the first pass from one that bounces back for more information.
