Ordinance or Law Coverage: Who Pays for Code Upgrades on a Roof Claim

Replacing a storm-damaged roof can trigger code items the old roof never had, such as an ice barrier at the eaves, drip edge, or a full tear-off of extra layers, and whether insurance pays for them depends on your policy’s ordinance or law coverage and its limit. Find both numbers, the coverage limit and the cost of the code items, before you sign a contract.

The assumption to drop is “if code requires it, insurance pays.” The California Department of Insurance’s guide to homeowners and renters insurance puts the risk directly: unless your policy has this coverage, “your insurance company may not pay for changes you may need to make to the structure of your home to bring it up to current building codes.”

Code Upgrades Are a Separate Cost From Storm Repair

A roof claim has two numbers, and they come from different parts of the policy.

The first is the cost to repair or replace what the storm damaged with materials of similar kind and quality. That is what the main dwelling coverage and its loss settlement terms pay, as explained in how homeowners policies cover roof damage.

The second is the extra cost of meeting today’s building code when the old roof was built to an earlier standard. If your 1990s roof had no ice barrier and your city now requires one on a re-roof, the ice barrier is not “like kind and quality” replacement; it is an upgrade the law forces. Ordinance or law coverage, sometimes called building code upgrade coverage, is the part of a policy written to pay that second number.

The California guide also warns that “some policies do not have building code upgrade (ordinance or law) coverage.” So the first question is whether you have it at all, and the second is how much it pays.

Roof Code Items That Can Raise a Claim’s Cost

Both local documents below trace back to the International Residential Code (IRC), but a model code binds you only in the form your state or city adopted, so the items that apply to your re-roof depend on that local version. Side by side, they show both the common items and how much they vary.

Lincoln, Nebraska publishes a re-roof policy (2021, based on the 2018 IRC), and Bloomington, Minnesota a reroofing information sheet (June 2023, based on the 2020 Minnesota Residential Code). Their lists compare like this:

The drip edge row shows why you cannot rely on a national list. The same IRC item is required in one city and amended out in another state. For what the code requires on a re-roof in general, see roofing building codes; for where ice barrier goes and why, see ice and water shield requirements.

Florida adds a rule of its own for partial repairs. Under section 553.844 of the 2026 Florida Statutes, when a roof built, repaired or replaced in compliance with the 2007 Florida Building Code or a later edition has 25 percent or more of its area repaired, replaced or recovered, “only the repaired, replaced, or recovered portion is required to be constructed in accordance” with the current code. Local governments may not amend that exception by ordinance. For a roof built to an earlier code, ask the building department what a repair of that size triggers, because the exception does not reach it.

Decking deserves a separate note. Sheathing replaced because the storm damaged it is a question for the main claim, while sheathing rotted by years of slow leaks is maintenance. Ask the building department whether your new roof covering carries any code requirement for the deck beneath it before you treat decking as a code upgrade.

Find Ordinance or Law Coverage and Read Its Limit

Start with the declarations page. Ordinance or law coverage may appear as its own line with a percentage or dollar limit, or as an endorsement listed by form number. Then read the endorsement itself.

Outside your own policy, state law can set a floor, and Florida is one example of a default. Section 627.7011 of the Florida Statutes (2026 edition) says a policy covering the dwelling “is deemed to include the law and ordinance coverage limited to 25 percent” of the dwelling limit unless the insured rejects it in writing, and that the insured may choose a limit of 25 percent or 50 percent. The coverage pays added costs to comply with laws and ordinances governing “the construction, use, or repair of any property,” including demolition and debris removal. These are Florida’s statutory options, not a national norm.

Hypothetical example: A policy has a $300,000 dwelling limit and ordinance or law coverage at 25 percent, a $75,000 limit. A re-roof’s code items cost $6,000 beyond like-kind replacement, so the limit covers them, subject to the endorsement’s terms. A policy with no ordinance or law coverage would leave the $6,000 to the owner.

Whatever state you are in, ask your insurer or agent these questions in writing:

1. Does my policy include ordinance or law coverage, and under which endorsement?
2. What is the limit, as a percentage of the dwelling limit or a dollar amount?
3. Does it pay only when the code work is actually completed?
4. Does it cover code work on undamaged parts of the roof that the building department requires as part of the repair?
5. Does it cover the added demolition and debris removal?

Get the Local Code List First

A request for code items is only as strong as your proof that the code requires them. Get that proof from the building department before you argue the estimate.

Ask the department, ideally in writing or from its published re-roof handout:

• Which code edition and local amendments apply to a re-roof at my address?
• How many existing layers can stay, and when is full tear-off required?
• Is an ice barrier required, and how far up the roof must it extend?
• Is drip edge required at eaves and gables?
• What underlayment is required on low-slope sections?
• Are chimney crickets required, and at what chimney width?
• Which inspections will the permit require?

The model text is the ICC’s IRC Chapter 9, Roof Assemblies, but your answer is whatever your jurisdiction adopted. Attach the department’s list to a supplement request, matched to the line items, using the checks in how to read an insurance roof estimate. The permit process itself is covered in the re-roof permit guide.

Will Your Policy Pay for These Code Upgrades?

Use the first rule that matches your policy:

• Coverage exists and the limit exceeds the code-item cost: request each code item in writing as an ordinance or law item, with the building department’s list attached.
• Coverage exists but the limit is lower than the cost: the policy pays up to the limit and you pay the rest; get the contractor to price each code item separately so the split is clear.
• No coverage: the code items are your cost. Budget for them before signing, and ask whether any of them is also needed to repair covered damage, which the main claim may cover.

If your roof is older than the current code, and especially if it has more than one layer, check this coverage at your next renewal rather than after a storm.

Before you sign a contract, find your policy’s ordinance or law limit, ask the building department for its re-roof code list, and have the code items priced separately on your contractor’s estimate.
