Ordinance or Law Coverage: How to Get Roof Code Upgrades Paid

An adjuster scopes a roof the way it was built — match the old shingles, replace what's damaged, done. The problem is that a roof torn off today has to go back on to today's building code, not the code from whenever the house was built. Ice barrier, drip edge, ventilation, full tear-off — current code often requires things the original roof never had.

That gap between "like for like" and "up to code" is exactly what Ordinance or Law coverage pays for. If you're not claiming code-required upgrades under it, you're leaving legitimate money — and sometimes a code-compliant roof — on the table.

What Ordinance or Law coverage is

A standard property policy pays to put the property back the way it was. But when a law or code requires you to rebuild differently, that costs more — and Ordinance or Law coverage is the part of the policy that pays the code-required difference.

It comes in three parts, usually labeled A, B, and C:

• Coverage A — undamaged portion. Pays for the value of the undamaged part of the structure that code forces you to tear out anyway.
• Coverage B — demolition. Pays to demolish and haul off that undamaged portion.
• Coverage C — increased cost of construction. Pays the extra cost of rebuilding to current code.

For roofing, Coverage C is the one that does the work — it's what covers the code upgrades a reroof triggers. One catch worth checking up front: Ordinance or Law is often capped (commonly around 10% of the dwelling limit) or sold as an endorsement, so confirm the policy actually carries it and how much.

Why code upgrades aren't "betterment"

The most common way carriers deny code items is to call them "betterment" — an upgrade that improves the home beyond its pre-loss condition, which the homeowner supposedly shouldn't get for free.

That argument fails when the upgrade is required by code. Betterment is a voluntary improvement — going from three-tab to designer shingles because you felt like it. A code upgrade isn't voluntary; the law won't let you put the roof back without it. When code mandates the work, it's covered under Ordinance or Law — not disallowed as betterment. The distinction is mandatory versus optional, and it's the whole ballgame on these denials.

The roof code upgrades Ordinance or Law commonly covers

These are the items current code frequently requires that an older roof didn't have — which makes them classic Coverage C upgrades.

A few of these are worth understanding, because adjusters push back on them:

• Drip edge wasn't required in older editions of the IRC — it became mandatory in more recent code. So on an older home, new drip edge at the eaves and rakes is a genuine code upgrade, not an add-on.
• Ice barrier (the self-adhering membrane running from the eave to a point inside the wall line) is required in regions with a history of ice damming. Many older roofs have plain felt where code now demands an ice barrier.
• Full tear-off is required, not optional, in several situations — two or more existing layers, water-damaged decking, or materials the new roof can't go over. A "recover" isn't code-legal in those cases even if the adjuster scoped one.

One important caveat: which code applies depends on the edition your jurisdiction has adopted. Codes are adopted locally, so the specific requirement — and even whether drip edge or ice barrier is mandatory — turns on your local code. Cite the version your city or county actually enforces.

The "25% rule" — mostly a Florida thing

You'll hear contractors talk about the "25% rule": if more than 25% of a roof is repaired or replaced within a 12-month period, the entire roof has to be brought up to current code. That rule is specific to Florida (Florida Building Code–Existing Building §706.1.1), not the model national code — so don't assume it applies in your state.

Florida also carved out a big exception: under SB 4-D, if the existing roof was built to the 2007 Florida Building Code or later and permitted after March 1, 2009, only the repaired portion has to meet current code.

The model IRC and IBC don't impose a 25% threshold. What they do require is full tear-off in the situations above — so even without a 25% rule, a "patch it like-for-like" scope often isn't code-compliant anyway. Know which rules your locally adopted code actually contains before you argue it.

How to claim Ordinance or Law on a roof

Getting these paid is a documentation exercise, and it looks a lot like any other supplement:

1. Confirm the coverage and the limit. Verify the policy carries Ordinance or Law and note the cap. If the code-required cost exceeds the limit, that's a conversation to have early.
2. Identify every code-triggered upgrade the reroof requires — ice barrier, drip edge, ventilation, tear-off, decking, fasteners.
3. Cite the specific code section, and the edition your jurisdiction enforces. "Code requires it" won't move an adjuster; "IRC R905.1.2, adopted by [jurisdiction]" will.
4. Claim it under the Ordinance or Law provision, not general coverage — that's the bucket the money comes from.
5. Frame it as mandatory compliance, not an upgrade. You're not improving the home; you're meeting a legal requirement to reinstall the roof at all.

This is the same discipline behind the line items adjusters miss — several of which (ice barrier, drip edge, ventilation) are code items — and it pairs with getting the labor priced correctly and the overhead and profit you're owed on the job.

Key takeaways

• Ordinance or Law coverage pays the increased cost of rebuilding to current code after a covered loss — Coverage C is the roofing-relevant piece.
• Code-required upgrades are not "betterment" — betterment is voluntary; code compliance is mandatory and covered.
• Common covered upgrades: ice barrier (IRC R905.1.2), drip edge (R905.2.8.5), ventilation (R806), and required full tear-off (R908) — subject to your locally adopted code edition.
• The "25% rule" is Florida-specific (FBC §706.1.1, with the SB 4-D post-2009 exemption), not model code.
• Claim it under the Ordinance or Law provision, cite the exact code section and local edition, and frame it as mandatory compliance.

Don't leave code upgrades unclaimed

Code upgrades are some of the highest-value — and most-denied — items on a roof claim. ClaimSpark reviews your claim documents, flags the code-required items an adjuster scoped "like for like," and builds an insurance-ready supplement package that ties each one to the code and the Ordinance or Law provision — for a flat fee per supplement, not a cut of your claim.
