Could your new roof lower your insurance bill?
Homeowners who compare quotes after a roof replacement often save hundreds of dollars a year. HowMuch.net lets you compare home insurance rates from multiple carriers in about an hour, with your new roof documented.
Does a new roof lower your home insurance?
Yes, in most cases, but the discount is the most oversold number in home improvement. A standard replacement typically moves your total premium by a single-digit percentage. The large figures you see advertised, 20% to 55%, apply only to impact-rated or certified roofs in states with credit rules, and they are applied to the wind, hail, or hurricane portion of your premium rather than the whole bill.
The bigger money is somewhere else. A new roof is often what keeps you insurable at all, and what moves your roof back to full replacement cost coverage instead of a depreciated payout that can cost you five figures on your next storm claim.
It is also the best moment you will ever have to shop your policy. Carriers price a brand-new roof very differently from one another, and homeowners who compare quotes right after a replacement often find savings of several hundred dollars a year beyond whatever credit their current insurer files.

How much does a new roof lower insurance?
Read any state program page closely and you will find the same phrasing: the credit applies to the wind, hail, or hurricane portion of the premium. That single detail is where almost all of the confusion on this topic comes from, and most roofing ads leave it out.
If you live on the Gulf Coast, wind is the majority of what you pay for, so a 30% wind credit is a large number in real dollars. If you live somewhere that wind and hail are a modest share of your rate, the same headline percentage barely moves the bill.
Geography drives the answer more than anything else. Texas shows the spread clearly. When the state ran a benchmark rate system, Commissioner's Bulletin B-0030-98 set mandatory impact-resistant roofing credits ranging from 1% in the lowest-hail territory up to 35% for a Class 4 roof in the highest-hail territories. That is the same roof in the same state earning a thirty-five-fold difference in credit, driven entirely by hail exposure. Those credits are no longer set by the state: TDI now states that the discount for each class of roofing material is established by each insurance company individually.
A realistic expectation for a like-for-like asphalt replacement outside the hail belt is somewhere between barely noticeable and a few hundred dollars a year. The large numbers show up when you upgrade the roofing system itself and live where the state has put rules behind it.
The only way to learn your own number is to get quotes with the new roof documented. The spread between carriers on the same house is routinely larger than any single credit on this page, which is why comparing after a replacement pays off even when your own insurer's discount looks small.

What your insurer is actually pricing
Underwriters score four things, and none of them is how the roof looks from the curb.
Age and remaining service life. This is the dominant variable. Claim frequency and severity climb sharply as roofs age, so age drives both your price and whether the carrier will write you at all.
Impact resistance. Roof coverings tested to UL Standard 2218 are graded Class 1 through Class 4, with Class 4 surviving the largest steel ball drop without cracking. Class 4 is the rating that earns real credits in hail markets.
How the roof is attached. In wind states, the fasteners and the sealed deck underneath matter as much as the shingle on top. Florida's wind mitigation form grades roof deck attachment from Level A up to Level D based on nail size, type, and spacing, and the higher levels carry the larger credits.
Shape and fire rating. A hip roof sheds wind load better than a gable and is credited for it. In wildfire states, a Class A fire rating is the qualifying feature instead.
Table 1: Which roof upgrades earn the largest credits
| Upgrade | What it certifies | Where it pays most |
|---|---|---|
| Class 4 impact-rated covering | Survives large hail impact without cracking (UL 2218) | Hail belt: TX, OK, CO, KS, NE, MN, WY |
| IBHS FORTIFIED Roof | Sealed roof deck, enhanced attachment, edge detailing, independently verified | Gulf and Southeast: AL, LA, MS, SC, OK, KY, NC, GA |
| Class A fire rating | Highest fire resistance classification | Wildfire states, notably CA |
| Hip roof geometry | Better wind uplift performance than a gable | Coastal wind states, notably FL |
| Upgraded deck attachment | Higher wind mitigation credit tiers | FL and other wind mitigation states |
The step up to an impact-rated or FORTIFIED system is usually a modest premium over a standard replacement, and it is often the difference between a token credit and a meaningful one. In the grant states listed further down, that upgrade may be fully funded. Use the roof replacement cost calculator to see what a standard replacement runs for your home before you price the upgrade.
Roof age and staying insurable
Roof age used to be a pricing question. It has become an eligibility question. In hail and hurricane exposed states, many carriers will not write new business on roofs past 15 or 20 years, and a growing number require an inspection at renewal on older roofs. A roof that fails that inspection can trigger non-renewal, a forced coverage change, or a demand that you replace it as a condition of keeping the policy.
Florida wrote homeowner protections into statute in response. Under Florida Statute 627.7011, an insurer cannot refuse to issue or renew a policy solely because of roof age if the roof is under 15 years old. For roofs 15 years and older, the insurer must let you obtain an inspection at your own expense, and cannot refuse solely on age if that inspection shows five or more years of useful life remaining.
Most states have no equivalent protection. In those markets, a new roof is what keeps you in the standard insurance market rather than a surplus lines or state-backed plan, and the price gap between those two is usually far wider than any discount discussed on this page.
Replacement cost vs actual cash value
This is the line item most homeowners never look at until they file a claim, and it is where the real money sits.
Replacement cost value pays what it costs to replace the roof today. Actual cash value pays that amount minus depreciation for age and wear. Many carriers now move older roofs onto an actual cash value settlement endorsement or a roof payment schedule for wind and hail losses, often once the roof passes 10 to 15 years.
Table 2: What the same claim costs under each settlement type
| Coverage type | Depreciation applied | Your out of pocket* |
|---|---|---|
| Replacement cost | None | $1,000 |
| Actual cash value | $10,000 | $11,000 |
*Based on a $20,000 roof with a $1,000 deductible, 10 years old, depreciating $1,000 per year.
A new roof frequently qualifies you to move back to full replacement cost coverage. That single change can be worth more than a decade of premium discount, which is why a roof replacement is the right time to reread your policy language along with your price.

State-by-state credits and roof grants
Several states now require insurers to discount certified roofs, and several fund grants that cover most or all of the upgrade cost. The rules changed substantially through 2026, so check current status before you sign anything.
Table 3: Mandated roof insurance credits and state grant programs
| State | Mandated insurance credit | Grant or tax incentive |
|---|---|---|
| Alabama | Yes. Ala. Code 27-31D-2 requires a discount for property retrofitted to IBHS FORTIFIED standards | Strengthen Alabama Homes: grants up to $10,000 for a FORTIFIED re-roof |
| California | Yes, conditionally. The Safer from Wildfires regulation requires insurers that vary price by wildfire risk to reflect mitigation, including a Class A roof | None statewide for roofing |
| Florida | Yes. Fla. Stat. 627.0629 requires actuarially reasonable wind mitigation discounts for roof covering, deck attachment, roof-to-wall connection, and roof shape | My Safe Florida Home: free wind mitigation inspection and grants up to $10,000 for eligible homes |
| Georgia | Not mandated | Georgia Underwriting Association mitigation program discounts |
| Kentucky | Yes. HB 256 (2024) requires insurers to offer a FORTIFIED discount, in effect since March 2026, plus an option to upgrade to FORTIFIED after a covered loss | Strengthen Kentucky Homes launched March 2026 with $5 million in initial funding: grants up to $10,000 for a FORTIFIED roof |
| Louisiana | Yes. LDI Regulation 136 sets mandatory discount benchmarks of 16% to 49% on the hurricane portion, tiered by region and FORTIFIED level (Roof, Silver, or Gold), to be implemented by January 1, 2027 | Louisiana Fortify Homes Program: grants up to $10,000 by lottery. State tax deduction up to $5,000 |
| Mississippi | Not mandated, but discounts reach up to 55% off the wind portion. MWUA offers a free FORTIFIED endorsement | Strengthen Mississippi Homes Act: grants up to $10,000, launched July 1, 2026 for wind pool policyholders of 3+ years, with statewide expansion expected in early 2027 |
| North Carolina | Not mandated | Coastal underwriting association discounts. Roughly 10,000 FORTIFIED homes statewide |
| Oklahoma | Yes. State law requires carriers to offer a discount for certified FORTIFIED roofs; filed discounts on the wind and hail portion run up to 42%, varying by carrier | Strengthen Oklahoma Homes: grants up to $10,000, available in all 77 counties. Pilot participants report average savings near $750 per year |
| South Carolina | Not mandated, but wind portion discounts reach 50% or more across numerous carriers | SC Safe Home: grants of $4,000 to $7,500. Tax credit of 25% of cost up to $1,000 |
| Texas | No longer set by the state. Insurers file their own impact-resistant credits | None statewide. A completed TDI Form PC068 is required for a TWIA credit |
| CO, KS, MN, NE, WY | Not mandated. Class 4 impact-resistant credits are widely offered voluntarily in hail-exposed territories | None statewide |
| CT, MD, NJ, NY, RI | Discounts available for specific wind-resistant features | Rhode Island offers a hurricane deductible waiver for completed mitigation |
These programs regularly close or run out of funding. Confirm current status with your state department of insurance before you sign a roofing contract, because several of these grants require approval before work begins and will not reimburse a job already underway.
What to send your insurer
The credit applies from the date you document it, and most carriers will not backdate. Collect these while your contractor is still on site, because chasing paperwork six months later is much harder.
- Final invoice showing the completion date, full scope, and total cost
- Permit and passed final inspection from your local building department
- Manufacturer specification sheets showing the UL 2218 class if impact-rated, and the fire rating
- Photos of the labeled shingle wrappers before they are hauled away, showing manufacturer, brand, year, and impact classification
- Wind mitigation inspection report if you are in a wind state, completed by a state-approved inspector
- FORTIFIED certificate and the evaluator's designation number if you built to that standard
- Contractor license number and the workmanship warranty document
Send them together, in writing, and ask three specific questions: what credit is being applied, what the effective date is, and whether your roof now qualifies for replacement cost loss settlement.
Report the roof, then re-shop the whole policy
Reporting the roof to your current carrier gets you their filed credit. Treat that number as a starting point, because another carrier may value the same roof far more.
Insurers differ enormously in how much they reward a new roof, because they differ in what they want to insure. A carrier pulling back from your zip code will apply the minimum credit it filed and keep pricing you as part of a book it is trying to shrink. A carrier actively competing for low-risk business in that same zip code will treat a certified new roof as exactly the profile it is hunting for. The same house with the same roof can come back with a very different quote.
The week your roof passes final inspection is the strongest negotiating position you will ever have on this policy. Your largest risk factor just reset to zero and the documentation is sitting in your hands. You also have not renewed yet at a rate that assumes the old roof, so waiting until renewal throws away the months in between.
Start by comparing home insurance quotes on HowMuch.net from at least three carriers on identical coverage. Check the roof loss settlement terms, the wind and hail deductible, and whether that deductible is a flat dollar amount or a percentage of your dwelling coverage. A quote that looks cheaper because it quietly moved your roof to actual cash value is not cheaper.
Frequently asked questions
Do I have to tell my insurance company I replaced my roof?
Yes, and promptly. Insurers do not receive permit data automatically. Most apply the credit from the date you document the work and will not backdate it, so every month you wait is a month of discount you do not get back.
Does a new roof lower insurance if I use the same materials?
Usually yes, because it resets your roof age, which is the variable underwriters weight most heavily. The larger credits require an upgrade to an impact-rated, wind-rated, or FORTIFIED system.
What is a Class 4 roof?
A roof covering that passed UL Standard 2218 at the highest impact resistance level, meaning it withstood the largest test impact without cracking. It is the rating that earns the largest hail-related credits, and it is worth asking your contractor to quote it as an option in hail country.
Can my insurer drop me because my roof is old?
In many states, yes. Carriers commonly decline or non-renew roofs past 15 or 20 years in hail and hurricane markets. Florida limits this by statute, but most states do not.
Is a metal roof cheaper to insure?
Often, because most metal systems carry both a Class A fire rating and strong impact and wind performance. How much it helps depends entirely on which perils your market prices for. See the metal roof cost guide for what the upgrade costs.
Will my insurance go up after a roof claim even if I replaced the roof?
A paid claim can affect your rate and your renewal regardless of the new roof. This is another argument for shopping the policy after replacement, since carriers weigh prior claims very differently from one another.
Should I wait for a state grant before replacing my roof?
If your state runs a roof grant program, check it before signing a contract. Several programs require approval in advance and will not reimburse work that has already started.
Put your policy out to bid
A new roof is the single biggest improvement you can make to how an underwriter sees your home. Make sure you are being paid for it. Compare quotes on matching coverage while the paperwork is fresh, and confirm the winning policy settles your roof at replacement cost rather than actual cash value.
Your roof just reset your biggest risk factor. See if you could save.
The week your roof passes final inspection is the strongest negotiating position you will ever have on this policy. Compare quotes on HowMuch.net before your renewal locks in a rate that assumed the old roof.
